Handbook of molecular force spectroscopy

Modern materials science and biophysics are increasingly focused on studying and controlling intermolecular interactions on the single-molecule level. Molecular force spectroscopy was developed in the past decade as the result of several unprecedented advances in the capabilities of modern scientific instrumentation, and defines 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, which typically target a specific range of experimental systems and geometries, include atomic force microscopy, optical tweezers, surface forces apparatus, and magnetic tweezers.

Group 13 Chemistry III : Industrial Applications

The present issue of Structure and Bonding is dedicated to applied group 13 chemistry, particularly for the elements boron and aluminum, and to a lesser degree gallium and indium. Although boron is a trace element (0.01 g kg 1) in the earth's crust, it has been concentrated in a few locations by geochemical processes and is relatively easy to mine as borax. Aluminum, on the other hand, is the most abundant metal in the earth's crust (82 g kg 1) and dispersed widely throughout the globe. In the chapter Schubert explains the close relationship between the basic properties of the boron compounds and their associated uses. The remaining four chapters focus, to some degree, on aluminum. Since a great deal of literature exists in this area, these chapters are more focused on areas of emerging utility, and contain a great deal of fundamental information. Uhl's contribution in Chapter 2 provides basic synthesis and structural information for aluminum and gallium hydrazides. These types of compounds are being explored as potential molecular precursors to metal nitrides such as the important blue green laser material gallium nitride.

Groundwater Geochemistry : A Practical Guide to Modeling of Natural and Contaminated Aquatic Systems

Numerical groundwater flow, transport, and geochemical models are important tools besides classical deterministic and analytical approaches. Solving complex linear or non-linear systems of equations, commonly with hundreds of unknown parameters, is a routine task for a PC. Modeling hydrogeochemical processes requires a detailed and accurate water analysis, as well as thermodynamic and kinetic data as input. Thermodynamic data, such as complex formation constants and solubility-products, are often provided as databases within the respective programs. However, the description of surface-controlled reactions (sorption, cation exchange, surface complexation) and kinetically controlled reactions requires additional input data. Unlike groundwater flow and transport models, thermodynamic models, in principal, do not need any calibration.

Green Chemical Reactions

Green Chemistry is an inventive science based on fundamental research towards the development of new sustainable chemical processes. There is a great need to create a new type of chemistry focused on a new production system, in order to prepare the younger generation to get a greener future. The globalization pushes the chemistry community to adopt ethical issues. In this prospect Green Chemistry can achieve the approval of the society by teaching students to be confident in science and at the same time by convincing people that it is possible to attain technological development with respect and care for the environment we live in. This is why it is of foremost importance that education and fundamental research remain strictly connected, so that democracy and development can grow and progress side by side.

Granite genesis : in-situ melting and crustal evolution

In this book we suggest an alternative model for the origin of granite in terms of in-situ meltingintracrustal convection that physically determines the process from partial melting of mid-upper crustal rocks to formation of a convecting magma layer. We illustrate the model using the geological, geochemical and geophysical studies from Australia, North and South America, Europe and China, and conclude that heat convection within a crustal partial melting layer is essential for formation of granite magma and that without convection, partial melting of rocks produces migmatites rather than granites. Granite is layer-like within the crust, and shape and size of granite bodies reflect the geometric relationship between an irregular upper surface of the crystallised magma layer and erosion surface. Repeated melting of the crust generates downward-younging granite sequences. Chemical and isotopic compositions of granites indicate differentiation within the magma rather than different deep sources.

Good laboratory practice : The why and the how

The GLP regulations have developed from rules on how to exactly document the planning, conduct and reporting of toxicity studies to a quality system for the management of a multitude of study types, from the simple determination of a physical/chemical parameter to the most complex field studies or ecotoxicology studies. At the same time the term “Good Laboratory Practice” has become somewhat of a slogan with the aim to characterise any reliably conducted laboratory work.

Geology and Ecosystems

This book includes an analysis of the relationship between the different geological, hydrochemical, hydrogeological and engineering-geological processes and the processes within surface ecosystems. The analysis of specific interactions between the lithosphere and biosphere provides an integrated concept of the role of the geological environment in the evolution of the biosphere. The practical significance of the book is reflected by the analysis of modern engineering activity associated with the mining of minerals, excessive groundwater withdrawal, disposal of industrial and domestic wastes (including radioactive wastes) and their impacts on all components of the environment. Geology and Ecosystems includes a scientific approach to the complex monitoring of the environment under different natural and anthropogenic conditions, including the monitoring of permafrost regions. An important part of the book is the analysis of the "water factor" impact on ecosystems and sustainable development. Influences of intensive groundwater extraction on river flow, vegetation and land subsidence are also considered.
