Häufig liegen natürliche und technische partikuläre Nanomaterialien (NM) in Formulierungen (i.d.R. Suspensionen, Emulsionen oder Suspoemulsionen) und Produkten vor, welche aus mehreren dispersen Phasen und komplexen Dispersionsmedien bestehen. Dabei gilt es, spezifische Grenzflächeneigenschaften der Partikel, ihre Wechselwirkungen untereinander und mit dem Dispersionsmedium zu berücksichtigen. Beispielsweise bestimmen die Grenzflächeneigenschaften, ob sich die Partikel eher in wässriger Phase oder in Lipidphase bzw. an deren Phasengrenzen anordnen. Die Grenzflächeneigenschaften werden maßgeblich durch die Adsorption gelöster Spezies beeinflusst, hängen also von der Zusammensetzung des Dispersionsmediums ab. In dieser Arbeit werden mit theoretischer und empirischer Forschung wie methodischer Vorgehensweise neue Beiträge zur Nanopartikelcharakterisierung erarbeitet. Die notwendige Ausarbeitung von Richtlinien an SOPs für die Charakterisierung von Nanopartikelsystemen wird hierbei berücksichtigt. Diese Richtlinien ermöglichen eine Anwendung im Kontext verschiedenartiger Analyseaufgaben, und die Ergebnisse können dem Leser dieser Arbeit unmittelbar Nutzen bringen.

This book describes different aspects of characterization and detection of nanomaterials in liquid disperse systems, such as suspensions, emulsions and suspoemulsions. Natural and technical particulate nanomaterials (NMs) are often present in formulations and products consisting of several disperse phases and complex dispersion media. Specific interfacial properties of the particles, their interactions with each other and with the dispersion medium, have to be considered. For example, the interfacial properties determine whether the particles tend to be arranged in aqueous or lipid phases or at their phase boundaries. The interfacial properties are significantly influenced by the adsorption of dissolved species, i.e., they depend on the composition of the dispersion medium. This poses great challenges for the characterization of these nanoparticle systems and requires adequate preparation methods. The nanoparticle measurement techniques aim at a deep physico-chemical understanding of the dispersity state of nanoparticle systems. Since the dispersity state of nanoparticle systems in an application usually does not correspond to their original manufacturing process, the formulation of new or improved product properties is of decisive importance. The characterization of nanoparticles in complex formulations or matrices requires an adequate sample preparation based on an existing or yet to be developed Standard Operating Procedure (SOP). The structure of the SOPs includes the dispersion regulations, which are of essential importance for comparing reproducible results of nanoparticle measurement with respect to comparability and transferability worldwide. The aim is to separate and isolate relevant NMs with knowledge of the interrelationships.

Graphene–electrolyte systems are commonly found in cutting-edge research on electrochemistry, biotechnology, nanoelectronics, energy storage, materials engineering, and chemical engineering. The electrons in graphene intimately interact with ions from an electrolyte at the graphene–electrolyte interface, where the electrical or chemical properties of both graphene and electrolyte could be affected. The electronic behavior therefore determines the performance of applications in both Faradaic and non-Faradaic processes, which require intensive studies. This book systematically integrates the electronic theory and experimental techniques for both graphene and electrolytes. The theoretical sections detail the classical and quantum description of electron transport in graphene and the modern models for charges in electrolytes. The experimental sections compile common techniques for graphene growth/characterization and electrochemistry. Based on this knowledge, the final chapter reviews a few applications of graphene–electrolyte systems in biosensing, neural recording, and enhanced electronic devices, in order to inspire future developments. This multidisciplinary book is ideal for a wide audience, including physicists, chemists, biologists, electrical engineers, materials engineers, and chemical engineers.

This dissertation contributes to the understanding of fundamental issues in the highly interdisciplinary field of colloidal science. Beyond colloid science, the system also serves as a model for studying interactions in biological matter. This work quantitatively investigated the scaling laws of the characteristic lengths of the structuring of colloidal dispersions and tested the generality of these laws, thereby explaining and resolving some long-standing contradictions in literature. It revealed the effect of confinement on the structuring, independently of specific properties of the confining interfaces. In addition, it resolved the influence of roughness and charge of the confining interfaces on the structuring and as well providing a method to measure the effect of surface deformability on colloidal structuring.

This book is concerned with functional nanomaterials, materials containing specific, predictable nanostructures whose chemical composition, or interfacial structure enables them to perform a specific job: to destroy, sequester, or detect some material that constitutes an environmental threat. Nanomaterials have a number of features that make them ideally suited for this job: they have a high surface area, high reactivity, easy dispersability, and rapid diffusion, to name a few. The purpose of this book is to showcase how these features can be tailored to address some of the environmental remediation and sensing/detection problems faced by mankind today. A number of leading researchers have contributed to this volume, painting a picture of diverse synthetic strategies, structures, materials, and methods. The intent of this book is to showcase the current state of environmental nanomaterials in such a way as to be useful both as a research resource and as a graduate level textbook. We have organized this book into sections on nanoparticle-based remediation strategies, nanostructured inorganic materials (e.g. layered materials like the apatites), nanostructured organic/inorganic hybrid materials, and the use of nanomaterials to enhance the performance of sensors.

Modern materials science and biophysics has increasingly focused on studying and controlling intermolecular interactions on the single-molecule level. The peer-reviewed literature contains an increasing number of studies that either measure the interaction forces directly or use mechanical forces to deform the molecules or trigger structural transitions. Molecular force spectroscopy is the result of unprecedented advances in the capabilities of modern force measurement instruments in the past decade and describes a number of techniques that use mechanical force measurements to study interactions between single molecules and molecular assemblies in chemical and biological systems. Examples of these techniques include atomic force microscopy, optical tweezers, surface forces apparatus, and magnetic tweezers. These techniques typically target a specific range of experimental systems and geometries, but all use mechanical force transducers to apply and detect nanonewton range forces between single molecules in condensed phases. Molecular force spectroscopy measurements have been very important for studies of adhesion and friction forces, where they provided the first truly nanoscale capabilities. Force spectroscopy has been instrumental in understanding mechanical properties and nanoscale dynamics of polymer systems from elasticity to nanoscale phase segregation. In biophysics, applications range from probing protein folding to direct mapping of intermolecular interaction potentials. This volume presents a review of modern force spectroscopy, including fundamentals of intermolecular forces, technical aspects of the force measurements, and practical applications. The Handbook begins with a review of fundamental physics of loading single and multiple chemical bonds on the nanometer scale with a discussion of thermodynamic and kinetic models of binding forces and dissipation effects in nanoscale molecular contacts, covers practical aspects of modern single-molecule level techniques, and concludes with applications of force spectroscopy to chemical and biological processes. Computer modeling of force spectroscopy experiments is addressed as well. In sum, Handbook of Molecular Force Spectroscopy is a comprehensive, authoritative guide to planning, understanding, and analyzing modern molecular force spectroscopy experiments with an emphasis on biophysical research.
