R3,347 Discovery Miles 33 470 Ships in 18 - 22 working days

This thesis reports a major breakthrough in discovering the superconducting mechanism in CeCoIn5, the "hydrogen atom" among heavy fermion compounds. By developing a novel theoretical formalism, the study described herein succeeded in extracting the crucial missing element of superconducting pairing interaction from scanning tunneling spectroscopy experiments. This breakthrough provides a theoretical explanation for a series of puzzling experimental observations, demonstrating that strong magnetic interactions provide the quantum glue for unconventional superconductivity. Additional insight into the complex properties of strongly correlated and topological materials was provided by investigating their non-equilibrium charge and spin transport properties. The findings demonstrate that the interplay of magnetism and disorder with strong correlations or topology leads to complex and novel behavior that can be exploited to create the next generation of spin electronics and quantum computing devices.

Huibin Wei
R2,635 Discovery Miles 26 350 Ships in 18 - 22 working days

This thesis describes a new approach for cell analysis by the rapid developing microfluidic technology. The nominee has made great contributions to develop a new analysis platform which combined microfluidic devices with mass spectrometry to determine the trace compounds secreted by cells. Based on this analysis platform, she studied the specific cell secreting behaviors under controlled microenvironment, of which the secretion compounds were qualified and semi-quantified by mass spectrometry. A novel cell sorting device integrated homogenous porous PDMS membrane was invented to classify cells from real samples based on the size difference. The nominee further studied the signal transmission between different cells, and the signal chemicals were qualitative and quantitative monitored by the analysis platform. This indicates the potential significant application of the new cell analysis platform in medicine screening and early diagnosis.

An understanding of the fate and behaviour of organic chemicals, such as surfactants, in the environment is a prerequisite for the sustainable development of human health and ecosystems. As surfactants are being produced in huge amounts, it is important to have a detailed knowledge about their lifetime in the environment, their biodegradability in wastewater treatment plants and in natural waters, and their ecotoxicity. Parameters relevant for the assessment of long-term behaviour, such as interactions with hormonal systems need to be understood to avoid unexpected adverse effects to future generations of people and the environment. However, the identification and quantification of commercial surfactants in the environment is made more complicated and cumbersome because they comprise of tens to hundreds of homologues, oligomers and isomers of anionic, nonionic, cationic and amphoteric compounds.
The EU-funded PRISTINE project (Priority surfactants and their toxic metabolites in wastewater effluents: An integrated study; ENV4-CT97-0494) provides the basis for the content of this title. It provides policy makers and industry with detailed information on analysis and concentrations of surfactants and their degradation products in the environment.
In addition to a general introduction to surfactants, this book comprises a comprehensive variety of analytical techniques, including sample handling, for the analysis of surfactants in the aquatic environment. Readers will find all the necessary information for analyzing the different groups of surfactants, with special emphasis on transformation products. Quality assurance is also reported on in detail. Chapters on toxicity and risk assessment are also included and give a complete perspective on the surfactants problem in the aquatic environment.

High-Resolution Experiments on Strong-Field Ionization of Atoms and Molecules - Test of Tunneling Theory, the Role of Doubly Excited States, and Channel-Selective Electron Spectra (Hardcover, 1st ed. 2016)
Lutz Fechner
R2,656 Discovery Miles 26 560 Ships in 18 - 22 working days

In this thesis, the ionization of atoms and small molecules in strong laser fields is experimentally studied using a reaction microscope. The population of autoionizing doubly excited states in the laser fields is proven and a possible connection to the well-known dielectronic recombination processes is discussed. The fundamental process of tunnel ionization in strong laser fields is subject of investigation in a pump-probe experiment with ultrashort laser pulses. A coherent superposition of electronic states in singly charged argon ions is created within the first, and subsequently tunnel-ionized with the second pulse. This gives access to state-selective information about the tunneling process and allows to test common models. Moreover, the ionization of krypton and argon at different wavelengths is studied, from the multiphoton to the tunneling regime. The wavelength-dependent investigations are furthermore extended to molecular hydrogen. In addition to ionization, this system might undergo different dissociative processes. Channel-selective electron momentum distributions are presented and compared to each other.

Surface plasmon resonance (SPR) has evolved into an exciting technique in biomolecular interaction analysis. The development of commercial SPR instruments has made the te- nique available to a wide scienti?c audience, and the number of publications in which the use of SPR is described is rapidly increasing. SPR is in use for many purposes from food quality control to the study of nanoparticles. Much research is now focused on devel- ing new SPR-related applications, e.g., SPR imaging, SPR arrays, SPR ?uorescence, and combinations of SPR with mass spectrometry and with electrochemistry. Biomolecular interaction analysis is at the core of many research projects. In principle, the setup of an SPR experiment is simple: There is a sensor surface to which one of the interacting partners (the ligand) is immobilized; the other partner (the analyte) is added in a ?ow or cell-like compartment. The binding phenomenon is monitored in real time as a change in SPR angle. An important issue is the choice of surface and the immobilization strategy. With SPR, it is possible to mimic the biological environment which is relevant for an interaction. For interactions in a water environment, sensor surfaces with hydrogels are available. Many biomolecular interactions take place in a membrane environment. For this, commercial sensor surfaces are available, or surfaces can be tailor-made. This volume contains several examples of building up of lipophilic surfaces. Nature abundantly makes use of multivalent interactions; multivalency can be mimicked on a sensor surface with immobilized ligands.

Simulation of materials at the atomistic level is an important tool in studying microscopic structures and processes. The atomic interactions necessary for the simulations are correctly described by Quantum Mechanics, but the size of systems and the length of processes that can be modelled are still limited. The framework of Gaussian Approximation Potentials that is developed in this thesis allows us to generate interatomic potentials automatically, based on quantum mechanical data. The resulting potentials offer several orders of magnitude faster computations, while maintaining quantum mechanical accuracy. The method has already been successfully applied for semiconductors and metals.

Scientists from many disciplines require making observations which are dependent upon the behavior of compounds in solution. This ranges from areas in geography, such as oceanography, to areas in chemistry, such as chromatography, to areas in biology, such as pharmacology. Historically, information would be obtained by observing a response for a given set of conditions and then the conditions would be changed and a new response obtained. In this approach there would be little effort made to actually understand how a compound was behaving in solution but rather just the response was noted. Understanding the behavior of compounds in solution is critical to understanding their behavior in biological systems. This has become increasingly important during the last twenty years as an understanding of the biochemistry related to human illness has become better understood. The development of the pharmaceutical industry and the need to rapidly screen large numbers of compounds has made scientists in the area of drug development aware that the pharmacological activity of compounds can be predicted by knowing their solution physical chemical properties. This is not to say that a specific drug-active site interaction can be predicted but rather a prediction can be made whether or not a compound will be absorbed, transported, or distributed within a physiological system in such a way that an interaction can occur.

Correlation Force Spectroscopy for Single Molecule Measurements (Hardcover, 2015 ed.): Milad Radiom Correlation Force Spectroscopy for Single Molecule Measurements (Hardcover, 2015 ed.)
Milad Radiom
R3,204 Discovery Miles 32 040 Ships in 18 - 22 working days

This thesis addresses the development of a new force spectroscopy tool, correlation force spectroscopy (CFS) for the measurement of the properties of very small volumes of material (molecular to m3) at kHz-MHz frequency range. CFS measures the simultaneous thermal fluctuations of two closely-spaced atomic force microscopy (AFM) cantilevers. CFS then calculates the cross-correlation in the thermal fluctuations that gives the mechanical properties of the matter that spans the gap of the two cantilevers. The book also discusses development of CFS, its advantages over AFM, and its application in single molecule force spectroscopy and micro-rheology.

The Essence of Chromatography (Paperback): Colin F. Poole The Essence of Chromatography (Paperback)
Colin F. Poole
R2,308 Discovery Miles 23 080 Ships in 10 - 15 working days

The knowledge base of chromatography continued to expand throughout the 1990s owing to its many applications to problems of contemporary interest in industry, life and environmental sciences. Organizing this information into a single text for a diverse group of scientists has become increasingly difficult. The present book stemmed from the desire to revise Chromatography Today, written by the same author with Salwa K. Poole, and published in 1991. This title is considered to be one of the definitive texts on chromatography. It was soon realized however, that a simple revision would not provide the desired result of a contemporary picture of the practice of chromatography at the turn of the century. The only workable solution was to start afresh, maintaining the same general philosophy and concept for Chromatography Today where possible, while creating essentially a new book.
The format of the new book is modular, with extensive cross-references to permit rapid location of related material using different separation concepts. Important features are extensive tabulation of essential data for performing separations and an extensive bibliography to the most recent literature.
This title is intended as a suitable text for graduate level courses in the separation sciences and as a self-study guide for professional chromatographers wishing to refresh their background in this rapidly expanding field.
The Essence of Chromatography presents a comprehensive survey of modern chromatography and is an effective replacement for Chromatography Today.
.Comprehensive and authoritative coverage of chromatographic techniques

R3,277 Discovery Miles 32 770 Ships in 10 - 15 working days

This thesis examines various aspects of excess excitation energy dissipation via dynamic changes in molecular structure, vibrational modes and solvation. The computational work is carefully described and the results are compared to experimental data obtained using femtosecond spectroscopy and x-ray scattering. The level of agreement between theory and experiment is impressive and provides both a convincing validation of the method and significant new insights into the chemical dynamics and molecular determinants of the experimental data. Hence, the method presented in the thesis has the potential to become a very important contribution to the rapidly growing field of femtosecond x-ray science, a trend reflected in the several free-electron x-ray lasers (XFELs) currently being built around the world. Light-induced chemical processes are accompanied by molecular motion of electrons and nuclei on the femtosecond time scale. Uncovering these dynamics is central to our understanding of the chemical reaction on a fundamental level. Asmus O. Dohn has implemented a highly efficient QM/MM Direct Dynamics method for predicting the solvation dynamics of transition metal complexes in solution.
