This thesis describes a proof-of-principle experiment demonstrating a technique for stable isotope enrichment called Magnetically Activated and Guided Isotope Separation (MAGIS). Over the past century many enriched isotopes have become available, thanks largely to electromagnetic separators called calutrons. Due to substantial maintenance and operating costs, the United States decommissioned the last of its calutrons in 1998, leading to demand for alternative methods of isotope separation. The work presented here suggests the promise for MAGIS as a viable alternative to the calutrons.The MAGIS technique combines optical pumping with a scalable magnetic field gradient to enrich atoms of a specific isotope in an atomic beam. Benchmarking this work against the calutron using lithium as a test case, the author demonstrated comparable enrichment in a manner that should scale to the production of similar quantities, while requiring vastly less energy input.
Electrochemical Sensor Analysis (ECSA) presents the recent advances
in electrochemical (bio)sensors and their practical applications in
real clinical, environment, food and industry related samples, as
well as in the safety and security arena. In a single source, it
covers the entire field of electrochemical (bio)sensor designs and
characterizations.
Detection of concealed explosives is a notoriously difficult problem, and many different approaches have been proposed to solve this problem. Nuclear quadrupole resonance (NQR) is unique in many ways. It operates in a safe AM radio frequency range, and it can remotely detect unique fingerprint (NQR spectrum) of many explosives, such as TNT or RDX. As such, the detection of target does not depend on the shape or material of the container, or the presence of metallic object such as triggers etc. Spectra of chemically similar compounds differ enough that their presence never causes interference or false alarms. Unfortunately, widespread use is prevented due to low sensitivity, radiofrequency interference from the noisy environment, and inability to detect liquid explosives. This book presents current state of the art of the attempts to overcome NQR sensitivity problem, either by increasing the strengths of signals generated, or by increasing the specificity of the technique through a better understanding of the factors that affect the quadrupolar parameters of specific explosives. The use of these specific quadrupolar parameters is demonstrated on signal processing techniques that can detect weak signals, which are hidden in a noisy background. The problem of differentiation of liquid explosives and benign liquids in closed containers is approached by measurements of different nuclear magnetic resonance (NMR) parameters. As shown, a couple of solutions has reached a prototype stage and could find their use in a near future."
Solid-State spectroscopy is a burgeoning field with applications in many branches of science, including physics, chemistry, biosciences, surface science, and materials science. Handbook of Applied Solid-State Spectroscopy brings together in one volume information about various spectroscopic techniques that is currently scattered in the literature of these disciplines. This concise yet comprehensive volume covers theory and applications of a broad range of spectroscopies, including NMR, NQR, EPR/ESR, ENDOR, scanning tunneling, acoustic resonance, FTIR, auger electron emission, x-ray photoelectron emission, luminescence, and optical polarization, and more. Emphasis is placed on fundamentals and current methods and procedures, together with the latest applications and developments in the field.
Dr Gy, a pioneer in every sense of the word, has spent 50 years studying the best way to take a truly representative sample. His greatest achievement perhaps has been to introduce science into the black art of sampling. The now famous and widely used formula bearing his name means that sampling is no longer a lottery but an essential analytical tool. This very readable and practical book, written by Pierre Gy himself, is the first simple guide to Pierre Gy’s method to be translated into English. Although Dr Gy’s formula was originally developed for the sampling of solid material in mines, etc., the theoretical arguments are equally valid for the sampling of liquids and multi-phase media. This book is as interesting as a historical perspective as it is useful for the practising modern day analyst.
Since the independent invention of DNA sequencing by Sanger and by
Gilbert 30 years ago, it has grown from a small scale technique
capable of reading several kilobase-pair of sequence per day into
today's multibillion dollar industry. This growth has spurred the
development of new sequencing technologies that do not involve
either electrophoresis or Sanger sequencing chemistries. Sequencing
by Synthesis (SBS) involves multiple parallel micro-sequencing
addition events occurring on a surface, where data from each round
is detected by imaging.
This review series covers trends in modern biotechnology, including all aspects of this interdisciplinary technology, requiring knowledge, methods, and expertise from chemistry, biochemistry, microbiology, genetics, chemical engineering and computer science.

With the development of new quantitative strategies and powerful bioinformatics tools to cope with the analysis of the large amounts of data generated in proteomics experiments, liquid chromatography with tandem mass spectrometry (LC-MS/MS) is making possible the analysis of proteins on a global scale, meaning that proteomics can now start competing with cDNA microarrays for the analysis of whole genomes. In LC-MS/MS in Proteomics: Methods and Applications, experts in the field provide protocols and up-to-date reviews of the applications of LC-MS/MS, with a particular focus on MS-based methods of protein and peptide quantification and the analysis of post-translational modifications. Beginning with overviews of the use of LC-M/MS in protein analysis, the book continues with topics such as protocols for the analysis of post-translational modifications, with particular focus on phosphorylation and glycosylation, popular techniques for quantitative proteomics, such as multiple reaction monitoring, metabolic labelling, and chemical tagging, biomarker discovery in biological fluids, as well as novel applications of LC-MS/MS. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective subjects, lists of necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Comprehensive and cutting-edge, LC-MS/MS in Proteomics: Methods and Applications presents the techniques and concepts necessary in order to aid proteomic practitioners in the application of LC-MS/MS to essentially any biological problem.
Channels of nanotubular dimensions exist in a variety of materials (examples are carbon nanotubes and the nanotubular channels of zeolites and zeotypes) and show promise for numerous applications due to their unique properties.

Biosensors are making a large impact in environmental, food, biomedical, and other applications. In comparison to standard analytical detection methods, such as minimal sample preparation and handling, they offer advantages including real time detection, rapid detection of the analytes of concern, use of non-skilled personnel, and portability. The aim of this book is to focus on research related to the rapid detection of agents and weapons of bioterrorism and provide a comprehensive review of the research topics most pertinent to advancing devices applicable to the rapid real-time detection of toxicants such as microbes, pathogens, toxins, or nerve gases. The ongoing war on terrorism and the rising security concerns are driving the need for newer faster biosensors against bio-warfare agents for both military and civil defence applications. The volume brings together contributions from the most eminent international researchers in the field, covering various aspects of work not so far published in any scientific journal and often going beyond the "state of art" . Readers of these review articles will learn new technological schemes that can lead to the construction of devices that will minimize the risk of bio-terrorism."
This book is about our ordinary concept of matter in the form of enduring continuants and the processes in which they are involved in the macroscopic realm. It emphasises what science rather than philosophical intuition tells us about the world, and chemistry rather than the physics that is more usually encountered in philosophical discussions. The central chapters dealing with the nature of matter pursue key steps in the historical development of scientific conceptions of chemical substance. Like many contemporary discussions of material objects, it relies heavily on mereology. The classical principles are applied to the mereological structure of regions of space, intervals of time, processes and quantities of matter. Quantities of matter, which don't gain or lose parts over time, are distinguished from individuals, which are typically constituted of different quantities of matter at different times. The proper treatment of the temporal aspect of the features of material objects is a central issue in this book, which is addressed by investigating the conditions governing the application of predicates relating time and other entities. Of particular interest here are relations between quantities of matter and times expressing substance kind, phase and mixture. Modal aspects of these features are taken up in the final chapter.
Fluorescent proteins are intimately connected to research in the life sciences. Tagging of gene products with fluorescent proteins has revolutionized all areas of biosciences, ranging from fundamental biochemistry to clinical oncology, to environmental research. The discovery of the Green Fluorescent Protein, its first, seminal application and the ingenious development of a broad palette of fluorescence proteins of other colours, was consequently recognised with the Nobel Prize for Chemistry in 2008. "Fluorescent Proteins I" is devoted to the basic photophysical and photochemical aspects of fluorescent protein technology. Experienced experts highlight colour tuning, the exploration of switching phenomena and respective methods for their investigation. The book provides a thorough understanding of primary molecular processes allowing the design of fluorescent proteins for specific applications.
