For most of the history of scientific endeavour, science has been recorded on paper. In this digital era, however, there is increasing pressure to abandon paper in favour of digital tools. Despite the benefits, there are barriers to the adoption of such tools, not least their usability. As the relentless development of technology changes the way we work, we need to ensure that the design of technology not only overcomes these barriers, but facilitates us as scientists and supports better practice within science. This book examines the importance of record-keeping in science, current record-keeping practices, and the role of technology for enabling the effective capture, reuse, sharing, and preservation of scientific data. Covering the essential areas of electronic laboratory notebooks (ELNs) and digital tools for recording scientific data, including an overview of the current data management technology available and the benefits and pitfalls of using these technologies, this book is a useful tool for those interested in implementing digital data solutions within their research groups or departments. This book also provides insight into important factors to consider in the design of digital tools such as ELNs for those interested in producing their own tools. Finally, it looks at the role of current technology and then considers how that technology might develop in the future to better support scientists in their work, and in capturing and sharing the scientific record.

This fully updated and expanded second edition of a highly popular text book focuses on the structure and mechanism in carbohydrate chemistry and biochemistry. Carbohydrates play important roles in biological systems as energy sources, as structural materials, and as informational structures (when they are often attached to proteins or lipids). Their chemical reactivity and conformational behaviour is governed by mechanistic and stereochemical rules, which apply as much to enzymic as to non-enzymic reactivity. The same principles of reactivity and conformation govern changes brought about in the process industries, such as pulp, paper and food. Extensively referenced with citations and a detailed index, the book contains everything the reader needs to know to start a carbohydrate research project with one of the real strengths being the treatment and integration of the important physical-chemical principles and methods (though lead references only are given to the finer points of carbohydrate synthesis). The book is suitable for both researchers who are new to the subject and those more established as well as a readership from diverse backgrounds and interests, including chemists, biochemists, food scientists and technologists involved with the processing of polysaccharides in the paper, textile, cosmetics, biofuels and other industries.

Science communication is a rapidly expanding area, and a key component of many final year undergraduate and postgraduate courses. Authored by a highly regarded chemist and science communicator, this textbook pulls together all aspects of science communication. Complete Science Communication focusses on four major aspects of science communication: writing for non-technical audiences and science journalism; writing for technical audiences and peer-reviewed journal writing; public speaking of science; and public relations. It first showcases how writing in a journalistic style is done and provides a guide for colloquially communicating science. Then, the art of writing scientific papers is conjoined to this idea to make technical manuscripts more digestible, readable, and, hence, citable. These ideas are next taken into the spoken word so that the scientist can engage in telling their science like that natural human art of campfire stories. Finally, all of these communication concepts are wrapped together in a discussion of public relations, providing the scientist with an appreciation for the marketing directors and news disseminators with whom they will work. Written in an accessible way, this textbook will provide science students with an appreciative understanding of communication, marketing, journalism, and public relations. They can incorporate these aspects into their own practices as scientists, allowing them to liaise with practitioners in the communication field.

Many of the polymers we use every day are highly flammable. Historically, a large number of home fires were caused by ignited polymeric materials until legislation was introduced requiring fire retardants to be added to these materials. Fire retardants increase the time it takes for materials to ignite, providing valuable time to prevent a fire or escape. However, it has become apparent that many of the traditional treatments used as fire retardants are harmful to human health and highly persistent in the environment. With evermore polymeric materials in our homes and lives it is still highly valuable to be able to make fire retardants, but consideration must be given to their environmental impact and sustainability. Green Fire Retardants for Polymeric Materials looks at both the choice of different materials and treatments for improving the fire retardancy of polymeric materials, as well as green approaches to synthesising these fire retardants. It is a timely resource both for green chemists interested in real world applications for their work and polymer scientists keen to increase the sustainability of their products and processes.

Billions of people globally live under conditions of water stress and water shortage, or with contaminated water sources. Anthropogenic contaminants pose an extra challenge as water purification technology must be constantly developed or upgraded to deal with newly fabricated pollutants. One of the UN sustainable development goals is to ensure availability and sustainable management of water and sanitation for all. Therefore, it is vital to develop novel materials and technologies for producing clean drinking water in a human safe, economically reasonable and environmentally sustainable way. Novel Materials and Water Purification introduces recent approaches to the fabrication of novel materials for water purification and discusses several significant applications including removal of heavy metals and pharmaceuticals. This is a timely work of high interest to researchers and learners in the fields of water science, water management and materials science.

Global climate change is the most important challenge humankind is facing in the modern era. One of the main scientific concerns is the monitoring of contaminants in the environment, which require the right environmental remediation strategies. In this context, nuclear magnetic resonance (NMR) techniques have a very important role in enabling the discovery of how pollutants are transformed, how they can move and how they can affect human health. This book discusses the present and the future perspectives of NMR techniques for environmental evaluations. It covers, amongst other topics, the importance of NMR as a contamination discovery tool, how to improve sensitivity in environmental NMR, and multiphase NMR for measurement of samples in their natural state. Samples include lubricant oils, soils and porous media. Due to the direct relationship between the environment and human health, there is information dedicated to the use of magnetic resonance imaging (MRI) to monitor human health as related to environmental pollution. There is also a chapter on how NMR is used in cultural heritage to measure artefacts directly affected by environmental pollution. Filling a gap in the literature, the book is for researchers explaining how to apply their knowledge of NMR techniques to solve environmental problems, and for students who want to deepen their understanding of this topic.

Tea is the world's most popular beverage. Dive into a cup of tea with a chemist and discover the rich molecular brew that can be extracted from the leaves of the Camellia sinensis plant. Tea contains over a hundred different chemical compounds which contribute to its colour, taste and scent – and its stimulating effects. The best-known is caffeine, but how does caffeine end up in tea and how can you get it out? Beginning with the leaves, Steeped explores the chemistry behind different styles of tea, from green teas to pu-erh. It tackles the age-old question of when, or even whether, to add milk. And it puts the chemistry to use with advice on how to brew a better cup.

Ionic liquids (ILs) play a crucial role in modern chemistry and chemical engineering. They remain more desirable than conventional volatile solvents and catalysts in many physical and chemical processes, often exhibiting green and designer properties for various applications. Examining the unique contribution of ILs towards current environmental challenges, this book addresses the importance of their role in the detection of micropollutants and decontamination processes in air and water compartments. It also presents a detailed review of how ILs impact the environment once released, a topic seldom covered in other books, and highlights novel chemoinformatic tools used to predict their fate, showing how advanced oxidation processes help in remediation. This is an ideal book for researchers in both academia and industry, and postgraduate students in environmental chemistry, chemical engineering and analytical chemistry looking at the potential applications of ionic liquids in addressing several environmental problems.

Proteins are an important nutrient and ingredient in food as well as in nutritional supplements. The application and take up of food proteins, especially plant proteins, has been limited due to their undesirable sensory properties, e.g. taste, odour, and chalky mouth feel. This will need to change if the availability of meat protein becomes scarcer. Documenting the latest research, this book is the first overview of the recent advances in flavour research of food proteins, with an emphasis on the major plant proteins, e.g. soy and pulse proteins. The topics to be covered include sensory and instrumental characterization of flavour compounds in food proteins, how flavour profiles in food proteins can be formed or altered, research advances of individual food proteins, the use of food protein products as flavouring ingredients, and future trends of flavouring food proteins. There is a growing interest in using plant proteins in food formulation and industrial applications, but no book has yet covered this systematically until now. Summarizing research advances in consumer studies and flavour chemistry that focus on food proteins, the book will discuss the flavour properties and problems in each major and novel food protein source for the academic and industry market.

Circadian rhythms have been shown to be ubiquitous and critically important in the experimental laboratory, accounting for the difference between life and death in response to identical stimulus. The partly endogenous nature of circadian rhythms has been well documented and methods for their characterisation have been developed enabling the cellular and molecular mechanisms to be understood. Chronobiology and Chronomedicine aims to provide a review of these mechanisms underlying circadian rhythms and illustrate the role of the brain's suprachiasmatic nuclei in the ‘pace-making'process and the effects caused by ‘clock genes'present in almost all cells. Beyond the mechanisms involved, the book discusses the relationship between body systems, disease, and proper circadian function; in particular, how disruption of the circadian rhythm is associated with ill health and disease status from observations made at the organismic level. The book is organised to be an ideal introduction for the postgraduate in various fields, reviewing developments and outlining methods to show the depth and breadth of chronobiology and chronomedicine, as well as an invaluable companion to researchers and healthcare professionals working in the field with an interest in developing novel therapeutic approaches.

This book details the latest research and development in the use of magnetic resonance imaging and spectroscopy as tools to give quantitative insights concerning late stage pharmaceutical formulation, tablet manufacturing and drug dissolution behaviour. The book combines different facets of magnetic resonance and highlights the use of spatial resolution (MRI) and how this adds to the knowledge base to further our understanding of the microscopic physicochemical processes occurring during drug release from solid dosage forms. New topics, that have not been thoroughly reviewed elsewhere, are covered including the applications of solution state magnetic resonance in process scale up, reaction monitoring/understanding and process analytical technologies (PAT); dissolution testing; and counterfeit analysis. Solid state NMR and its role in understanding phase separation in dispersions, polymorphism and crystallography are included and magnetic resonance imaging and its use in assessing tablet dissolution performance, mass transport and mixing in hot melt extrusion (HME) are covered.Focusing on late stage development rather than molecular drug discovery provides a unique approach and the book will appeal to a diversity of disciplines using spectroscopy for study. Aimed at researchers in drug development, manufacture and formulation in both industry (pharmaceutical companies) and academia (pharmacy program), it includes examples, where appropriate, of studies on commercially available pharmaceutical products.

This book fills a gap in the literature by comprehensively summarizing and discussing new advanced experimental techniques for their analysis. Providing a comprehensive overview of advanced biophysical methods for the characterization of molecular mechanisms of molecular chaperones, the majority of the contributions are NMR methodology. This is the method of choice for atomic resolution studies of such systems. Additional notable biophysical approaches are considered to present all relevant current developments in exploring chaperone function and the transient and dynamic interactions with their client proteins. The book is targeted at both current practitioners of structural biology and biophysical chemistry and scientists who are interested in entering the field. It could be useful for graduate students as supplementary reading.

In recent years, there has been a lot of interest in using nanotechnology in medicine to diagnose and cure various infectious diseases. Although the precise mechanism of action is frequently challenged, many nanosized materials have been extensively explored for this purpose, using their innately unique features. Their functionality has also been enhanced by the addition of various coatings, such as those that increase chemical stability and stealth properties or contain targeting agents that lessen off-target effects while producing effective'smart'nanoplatforms for the early detection, treatment, and possibly resolution of diseases. This book aims to compile research and review articles that concentrate on the synthesis, characterization, and applications of nanomaterials, such as nanoparticles, with a focus on investigating novel ways to improve their properties and create new efficient diagnostic, therapeutic, or theranostic approaches with a clear understanding of how they work.

Flexible metal–organic frameworks (MOFs) are a unique class of porous materials that feature stimuli-responsive flexible structures and dynamic structural transformation behaviours. Exhibiting structural changes in response to physical or chemical stimuli creates related functions that can be developed for practical applications. The specific components and architectures of flexible MOFs are key to their unique properties, so understanding their chemistry is of critical importance for more targeted construction and functional research. This book provides an accessible overview of the historical background of the chemistry of flexible MOFs and their features; in particular, design and synthesis, dynamic structure analysis, flexibility, function and theoretical treatment, and interpretation of the mechanisms as well as their applications. It gives readers a fundamental understanding of this chemistry and will be of great help to young researchers, as well as those already familiar with conventional porous materials in creating new materials.

There is an increasing awareness that materials and chemicals produced from fossil fuels are not sustainable, both in terms of the pollution caused by the extraction and production processes, and the fact that there is only a finite supply of these fossil fuels. Therefore, there is a strong incentive to find sources for chemicals and materials from source materials that we know we can continue to generate. Plants are a source of a wide variety of chemicals, many with interesting properties, and these chemical feedstocks are considered renewable rather than finite. Green Chemistry and Green Materials from Plant Oils and Natural Acids covers the application of these natural materials in producing polymers, lubricants and plasticisers.

Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are extensively used in consumer products, despite their high persistence and other hazards. The risks posed by this chemical class to human health and the environment, which are increasingly becoming understood, have triggered regulation and policy changes. However, safer alternatives to these technically effective materials and methods to discover and use those alternatives are still under development. Remediation of PFAS contaminated sites will not solve the growing worldwide pollution, but substitution with safer substances at the formulation and manufacturing phases will at least abate the flow of PFASs into our bodies and environment. Introducing safer alternatives to some of the PFASs of concern used in select industry sectors, this book informs the reader about the processes of chemical hazard and alternatives assessment that can foster innovation. It is a valuable resource for both green chemists and industrial chemists interested in how they can make their products safer without compromising on function.

We rely upon plastics for a great many functions in everyday life, from the cases of consumer electronics to disposable cutlery, plastics are versatile and convenient. However, with the supply of fossil fuels from which fossil-based plastics are derived becoming smaller and more expensive the need for alternatives is becoming increasingly apparent. Policy makers, environmentalists and consumers are increasing pressure on plastics manufacturers to look for greener alternatives to fossil-based plastics. Bioplastics are materials that are derived wholly or partially from biomass feedstocks, making them renewable, whilst maintaining the desirable properties of fossil-based plastics. Many, although not all, bioplastics are also more readily degradable than conventional plastics, a property increasingly desired by consumers. A variety of different bioplastics have already been developed and the field continues to grow. This book provides a comprehensive overview of the diverse subjects relating to bioplastics, including materials science, manufacture and processing and social and environmental impacts. It provides a valuable introduction both for those studying plastics at a graduate level and those starting to work in the field.

The cost of drug development is increasing, and investment returns are decreasing. The number of drugs approved by FDA is in decline in terms of the number of new molecular entities (NMEs). Amongst the reasons noted for this are the adverse side effects and reduced efficiency of many of the potential compounds. This is a problem both for the pharmaceutical industry and for those suffering from diseases for which there are no or few available treatments. Advances in computational chemistry, computer science, structural biology and molecular biology have all contributed to improved drug design strategies and reduced the time taken for drug discovery. By interfacing cheminformatics and bioinformatics with systems biology we can create a powerful tool for understanding the mechanisms of patho-physiological systems and identifying lead molecules for various diseases. This integration of drug design approaches can also play a crucial role in the prediction and rationalization of drug effects and side effects, improving safety and efficacy and leading to better approval rates. Addressing the lack of knowledge on the fundamental aspects of the various computational tools for drug discovery, this book is a compilation of recent bioinformatics and cheminformatics approaches, and their integration with systems biology. Written primarily for researchers and academics in chem- and bioinformatics, it may also be a useful resource for advanced-level students.

Antibiotic resistance is a global health concern. Strains of pathogenic microorganisms that have developed resistance to multiple antibiotics, such as MRSA, are extremely difficult to treat, and alternative methods for tackling pathogenic microorganisms are in demand. One potential target for new therapeutics is inhibition of quorum sensing: how microorganisms communicate and form biofilms in a density-dependent manner. Inhibiting this system via ‘quorum quenching'(QQ) is a promising route to new pharmaceuticals and for controlling biofilm formation and growth. Quorum sensing also provides interesting possibilities in synthetic biology for producing novel products, biosensors, bioactive molecules, and so on. This book covers the biology of quorum sensing and quenching, and potential sources of QQ enzymes and other inhibitors, as well as an overview of their mechanism and potential biotech applications. The book also covers the potential for new drug development from QQ, covering a range of related topics including protein engineering, imaging and computational studies, and integrated systems. This book is an ideal companion to researchers in chemical biology and medicinal chemistry, particularly those interested in biofilm formation, quorum sensing, novel antimicrobial development, synthetic biology and enzymology.

The book is ideal for postgraduates, analytical chemists, biomedical scientists and researchers in both academic and industrial settings working on materials science, chemical science and nanotechnology.

Sustainability from an economic and environmental perspective is linked to the way we extract and consume the earth's finite resources and is implicit in the definition of a circular economy (CE) as a model of production and consumption designed to retain value within the economic system. This can include conserving natural resources, making sustainable products by incorporating recyclability in product design, changing consumption behaviour, and adopting more sustainable business models. The UN Sustainable Development Goals (SDGs) are a set of objectives for improving health and education, reducing inequality, and protecting our shared environment globally. The CE is a key enabler to achieving these objectives. The Circular Economy explores how the concepts of CE can help address and meet targets linked to the SDGs. Taking a broad view across different industries and areas, and looking at specific SDGs, this book discusses current activities, standards, policy and legislation, challenges to achieving the SDGs and opportunities for enhancing circularity and sustainability.

In the human body, there are millions of living microorganisms involved in protecting the body from invaders, helping digestion and regulating moods, but there are also harmful pathogens that cause infectious diseases. For instance, the coronavirus (COVID-19) has caused considerable loss of life since its outbreak. Comprehensive analysis and characterization of microbes is of significant importance to understand the function and role of microorganisms, and rapid detection and identification of unknown pathogens are essential in early diagnosis, treatment monitoring and personalized medicine. Mass spectrometry is a technique to ionize molecules and detect the mass-to-charge ratio of the generated ions. The technique is widely used in hospitals for pathogenic bacteria identification, as well as in environmental science and food science for biosafety control. This book summarizes the most recent development of mass spectrometry techniques in microbial analysis, including mass spectrometry-based microbial identification, bacterial antimicrobial resistance study, data mining algorithm development, omics for microbial research, applications in clinical diagnosis, environmental science and food science, and more. It will guide researchers in the field, and those who are about to enter the field, in the most appropriate methods to characterize microbes and enable their detection.

Transportation currently takes up around a third of overall energy usage, of which the majority is petroleum-based gasoline. Petroleum is both a finite resource and a big contributor to the carbon emissions that are causing climate change. To continue to benefit from transportation whilst mitigating climate change it is essential to find alternatives to petroleum-based gasoline. Although a lot of recent developments have focused on electrifying transport the infrastructure for large scale uptake of electric vehicles is still lacking and it may be less practical in some parts of the world than others. Biofuels, therefore, still have a role to play in improving the sustainability of our transportation systems. The term green gasoline refers to biofuels intended to be direct drop-in replacements for petroleum-based gasoline. Such products allow vehicles to run on biofuel without any engine modifications and, being made from biomass, they are both renewable and have a better carbon emission profile than petroleum-based gasoline. Green Gasoline covers a range of new technologies being used to produce these biofuels and compares them to petroleum-based fuels in terms of sustainability. It will be an interesting read for those working in fuel chemistry as well as green chemists and anyone with an interest in transport sustainability.

Currently the majority of carbon-based feedstocks come from fossil fuels of which there is a finite supply. Methane is an abundantly available carbon-based feedstock, with large amounts now available through fracking and renewable sources available from biogas plants. However, methane is not very chemically reactive. One of the remaining “grand challenges” in chemistry is the development of clean, efficient, affordable processes that allow methane to be converted to other high value molecules. Highlighting the recent advances in methane activation and direct conversion processes this book discusses the progress and current state of the art for a wide variety of alternative methane activation and subsequent conversion processes, including homogeneous- and heterogeneous catalytic, electrocatalytic and pyrolytic systems. It is a useful resource for anyone working in green chemistry, catalysis and chemical engineering.

With applications across chemistry, physics and medicine, nuclear magnetic resonance is a proven, uniquely versatile and powerful spectroscopic technique. The success of NMR and its constant redevelopment means that the literature is vast and wide-ranging. Each chapter in this volume is a distillation of the key recent literature in different areas, covering the spectrum of NMR theory and practice, and including theory and computation of nuclear shielding, NMR of soft matter, hyperpolarisation techniques and NMR of living systems. These reports are invaluable both for new researchers wishing to engage with literature for the first time, and for seasoned practitioners, particularly service managers, needing to keep in touch with the ever-expanding ways in which NMR is used.

While our five senses are doing a reasonably good job at representing the world around us on a macro-scale, we have no existing intuitive representation of the nanoworld, ruled by laws entirely foreign to our experience. This is where molecules mingle to create proteins; where you wouldn't recognize water as a liquid; and where minute morphological changes would reveal how much'solid'things, such as the ground or houses, are constantly vibrating and moving. Following in the footsteps of Nano-Society and Nanotechnology: The Future is Tiny, this title introduces a new collection of stories demonstrating recent research in the field of nanotechnology. This drives home the fact that a plethora of nanotechnology R&D will become an integral part of improved and entirely novel materials, products, and applications yet will remain entirely invisible to the user. The book gives a personal perspective on how nanotechnologies are created and developed, and will appeal to anyone who has an interest in the research and future of nanotechnology. Reviews of Nanotechnology: The Future is Tiny:'The book is recommended not only to all interested scientists, but also to students who are looking for a quick and clear introduction to various research areas of nanotechnology'Angew. Chem., 2017, 56(26), 7351–7351'Once you start reading you will find it very difficult to stop'Chromatographia, 2017, 80, 1821

The medical MRI community is by far the largest user of diffusion NMR techniques and this book captures the current surge of methods and provides a primary source to aid adoption in this field. There is a trend to adapting the more advanced diffusion encoding sequences developed by NMR researchers within the fields of porous media, chemical engineering, and colloid science to medical research.

Historically the field of heterogeneous catalysis has focused on the design and optimisation of the catalytic materials. However, as these optimisations start to reach diminishing returns, attention has turned to non-conventional means for improving reaction conditions such as the use of ultrasound, plasma, electromagnetic heating and microwave heating. Microwave-assisted catalysis has been demonstrated to be useful in a wide range of applications including ammonia synthesis, desulfurization and production of chemicals from biomass. Advances in Microwave-assisted Heterogeneous Catalysis begins with the basics of microwave heating and the role of microwaves in heterogeneous catalysis. It goes on to cover the mechanisms of microwave specific reaction rate enhancement, microwave-assisted synthesis of porous, nonporous and supported metal catalysts, microwave augmented reactor technology and microwave-induced catalysis. The application of microwave-assisted heterogeneous catalysis in various fields of energy conversion, environmental remediation, and bulk and specialty chemicals synthesis are also discussed, making this a great reference for anyone involved in catalysis research.

Completely revised and updated, this 2nd Edition of Reactivity and Mechanism in Organic Chemistry is an ideal introduction to the quantitative description of organic reactivity for students in undergraduate and masters chemistry programmes. The book proceeds logically from qualitative molecular orbital theory as a tool for the description of bonding phenomena to combining this with thermochemical data to rationalise concepts such as molecular strain and hyperconjugation. Next, transition state theory, for examining organic reactivity phenomena, is introduced and its relation to energy surfaces and simple rate equations is discussed. On this basis more specific reactivity concepts commonly used in organic chemistry are explored such as the Bell–Evans–Polanyi principle, Marcus theory, HSAB principle, Hammett correlations, the Mayr–Patz equation, and FMO theory. How these reactivity models are applied is demonstrated for pericyclic reactions and selected rearrangement reactions involving transient intermediates such as radicals, diradicals, or carbocations, and for reactions involving classical electrophile/nucleophile combinations.

Ever wondered if the chemical processes taking place in space could be related to the origins of life? The authors of this book, both experienced astrochemists, embark on a discussion to find the answers to this question and more, and include a general introduction to astrochemistry for chemistry students. They explore chemistry occurring in the universe from its very early beginnings until the present era. Based on our current understanding, astrochemistry is known to occur in interstellar gas, on dust grains and in interstellar ices, in stellar atmospheres and envelopes, in dense star- and planet-forming regions, and on planets and other bodies in planetary systems. Recent observational discoveries supported by remarkable laboratory work emphasize chemical complexity, leading to answers to the tantalizing question: can this complexity be related to the origin of life? This book provides the tools to enable chemistry students to make their own computational investigations of astrochemistry and directs study across the chemical sciences and astronomy. Concentrating on fundamental processes, this book is a useful teaching aid.

This annual review provides critical analysis of the literature on photochemistry and its applications for anyone wanting to keep up to date with the field. Combining reviews on the latest advances in photochemical research with specific topical highlights, this book is the primary resource for anyone wanting succinct and rich information. The volume starts with periodical reports of the recent literature on physical and inorganic aspects, including the molecules of colour, light induced reactions in cryogenic matrices, photobiological systems studied by time-resolved infrared spectroscopy, photophysics and photochemistry of transition metal complexes, recent advances in photocatalytic water splitting, and finally a chapter on time-resolved spectroscopy application of LFP to heterogeneous photocatalysis. Coverage continues in the second part with highlighted topics including, among others, transition metal complexes-based photochemotherapy, advances in polaritonic photochemistry, synthetic strategies based on halogen atom transfer processes and photochemical water oxidation using metal-based chromospheres. This volume will again include a third section entitled SPR Lectures on Photochemistry, providing examples introducing academic readers to a photochemistry topic and precious help for students in photochemistry.

Mass spectrometry is one of the most versatile analytical techniques due to the vast range of analytes that it can detect and quantify and, as such, for its contribution to a significant number of life science fields. The legal and forensics community has certainly benefited from this technique, which has been able to provide reliable evidence in court cases. Liquid Chromatography/Gas Chromatography–Mass Spectrometry (LC/GC–MS) still have a dominant role in the provision of forensic intelligence. However, in the past decade new and exciting MS-based techniques have emerged and are or have evolved to be at an operational deployment maturity, enabling either fast, ambient, non-destructive, or portable screening (or encompass all of these features). In this book, developments of LC–MS and GC–MS based techniques are covered with respect to operational practice and new applications, accompanied by other MS-based techniques that are increasing forensic opportunities and that operate on a variety of evidence types. Whilst the underpinning working principles of each relevant mass spectrometry technique are summarised, each chapter primarily focuses on its implementation in criminal investigation and court cases. In the last chapters, this book additionally covers emerging MS technologies that are at the beginning of their operational implementation journey as well as niche applications outside the fields of traditional forensic science but with a clear potential to impact future investigations (forensics beyond the courtroom). This book provides an up-to-date reference for the mass spectrometry-based tools that are currently available both as established and as emerging methods within forensic practice. It will help casework commissioning managers and forensic providers worldwide to make more informed decisions as to the forensic strategy and workflow when examining exhibits. It is also recommended to postgraduates and early career investigators with reference to the contribution that these techniques and methods could make if applied to classic forensic science practice.

Over the last decade, there has been a significant shift from traditional mechanistic and empirical modelling into statistical and data-driven modelling for applications in reaction engineering. In particular, the integration of machine learning and first-principle models has demonstrated significant potential and success in the discovery of (bio)chemical kinetics, prediction and optimisation of complex reactions, and scale-up of industrial reactors. Summarising the latest research and illustrating the current frontiers in applications of hybrid modelling for chemical and biochemical reaction engineering, Machine Learning and Hybrid Modelling for Reaction Engineering fills a gap in the methodology development of hybrid models. With a systematic explanation of the fundamental theory of hybrid model construction, time-varying parameter estimation, model structure identification and uncertainty analysis, this book is a great resource for both chemical engineers looking to use the latest computational techniques in their research and computational chemists interested in new applications for their work.
