The last two decades have seen a renaissance in interest in the chemistry of the main group elements. In particular research on the metals of group 13 (aluminium, gallium, indium and thallium) has led to the synthesis and isolation of some very novel and unusual molecules, with implications for organometallic synthesis, new materials development, and with biological, medical and, environmental relevance. The Group 13 Metals Aluminium, Gallium, Indium and Thallium aims to cover new facts, developments and applications in the context of more general patterns of physical and chemical behaviour. Particular attention is paid to the main growth areas, including the chemistry of lower formal oxidation states, cluster chemistry, the investigation of solid oxides and hydroxides, advances in the formation of III-V and related compounds, the biological significance of Group 13 metal complexes, and the growing importance of the metals and their compounds in the mediation of organic reactions. Chapters cover: general features of the group 13 elements group 13 metals in the +3 oxidation state: simple inorganic compounds formal oxidation state +3: organometallic chemistry formal oxidation state +2: metal-metal bonded vs. mononuclear derivatives group 13 metals in the +1 oxidation state mixed or intermediate valence group 13 metal compounds aluminium and gallium clusters: metalloid clusters and their relation to the bulk phases, to naked clusters, and to nanoscaled materials simple and mixed metal oxides and hydroxides: solids with extended structures of different dimensionalities and porosities coordination and solution chemistry of the metals: biological, medical and, environmental relevance III-V and related semiconductor materials group 13 metal-mediated organic reactions The Group 13 Metals Aluminium, Gallium, Indium and Thallium provides a detailed, wide-ranging, and up-to-date review of the chemistry of this important group of metals. It will find a place on the bookshelves of practitioners, researchers and students working in inorganic, organometallic, and materials chemistry.

A compelling and compassionate case study approach to a broad range of neuropsychological disorders Neuropsychological Assessment and Intervention for Childhood and Adolescent Disorders focuses on the neuropsychological assessment and evidence-based practices available for assessing and treating children living with the etiological and neurological components of various disorders. Each chapter provides one or more case studies along with helpful background information, assessment results, and recommendations based on assessment data. Bridging science and practice, the book reviews the scientific literature, research on clinical implications, and evidence-based treatment of such disorders as: Dyslexia and Dyscalculia Specific Language Impairment/Dysphasia Autism Spectrum Disorders Attention-Deficit/Hyperactivity Disorder Tourette Syndrome Traumatic Brain Injury Childhood Cancer Epilepsy Cerebrovascular Disease Low Birth Weight Environmental Toxin Exposure Neurotoxins, Pregnancy, and Subsequent Disorders Chromosomal Anomalies Neurocutaneous Disorders Metabolic Disorders Each case study complements the content of each chapter by illustrating how the assessment process can inform intervention efforts for children. In addition, the cases humanize the effects of various disorders and demonstrate the usefulness of neuropsychological information in treatment and intervention planning, especially within children's educational and social contexts.

Each of the many different varieties of silica is characterised by its crystalline or amorphous structure and its specific physico-chemical surface properties. It is these surface characteristics which determine the applications of the silica, be it for chromatography, dehydration, polymer reinforcement or other processes. All the recent advances in the use of established and more modern methods for the determination of the surface and morphological characteristics of silicas, are found in this book written by a team of European experts. Analytical methods discussed include: solid state nuclear magnetic resonance, infra-red spectroscopy and adsorption methods. Emphasis is given to the nature and distribution of hydroxyl groups on silica surfaces; the final chapter gives a general survey of the health and safety aspects of silica.
