Lasers are relatively recent additions to the analytical scientist's arsenal. Because of this, many analysts-whether their concern is research or some range of applications-are in need of a tutorial introduction not only to the principles of lasers, their optics, and radiation, but also to their already diverse and burgeoning applications. The artic1es presented in this volume, carefully enhanced and edited from lectures prepared for the ACS Division of Analytical Chemistry 1979 Summer Symposium, are designed to provide just such a broad introduction to the subject. Thus, in addition to several excellent chapters on laser fundamentals, there are many practically oriented artic1es dealing with laser analytical methodology, inc1uding techniques based on the absorption oflaser radiation, on laser-induced fluorescence, and on some of the uses of lasers in chemical instru mentation. The first of these sections is pivotal and reflects in part our philosophy in organizing this collection. The authors of the initial chapters were invited not only because of their expertise in the field of lasers and analytical chemistry, but also because their didactic approach to writing and their c1arity of presentation were well known to us. It is our hope that individual readers with little knowledge of lasers will gain from these introductory chapters sufficient information to render the later, more detailed artic1es both useful and meaningful."

Detection canines have been utilized throughout the world for over a century, and while numerous attempts have been made to replicate the canine's ability to detect substances by mechanical means, none has been as successful. The olfactory system is a highly intricate and sophisticated design for chemical sensing, and the olfactory capacity of many animals, including canines, is considered unmatched by machine due to not only their great sensitivity and superior selectivity but also their trainability and mobility. These unique features have led to the use of such animals as "whole-animal" biosensors. Amplifying the benefits and diminishing the limitations of detection canines' interdisciplinary research is crucial to understanding canine olfaction and detection and enhancing this powerful and complex detector. The past 50 years have produced vast advancements in animal behavior/training technology to develop canines into more proficient and reliable sensors, while scientific research has provided tremendous support to help practitioners better understand how to utilize this powerful sensor. This book assembles a diverse group of authors with expertise in a variety of fields relating to detection canines and the chemical sensing industry, including both research and operational perspectives on detection canines. It illustrates how science enhances our understanding of how canines are employed for solving some of the world's leading detection challenges.

This thesis represents a breakthrough in our understanding of the noise processes in Microwave Kinetic Inductance Detectors (MKIDs). While the detection of ultraviolet to near-infrared light is useful for a variety of applications from dark matter searches to biological imaging and astronomy, the performance of these detectors often limits the achievable science. The author's work explains the limits on spectral resolution broadening, and uses this knowledge to more than double the world record spectral resolution for an MKID suitable for optical and near-IR astrophysics, with emphasis on developing detectors for exoplanet detection. The techniques developed have implication for phonon control in many different devices, particularly in limiting cosmic ray-induced decoherence in superconducting qubits. In addition, this thesis is highly accessible, with a thorough, pedagogical approach that will benefit generations of students in this area.

Analytical techniques are powerful tools in a chemist's armoury. Spectroscopic data and chemical information are used routinely in laboratories to follow a chemical reaction or elucidate a chemical structure. However, the sophistication of the analytical techniques used changes rapidly, hence the routinely used method of today can all too readily be superseded by the new technology of tomorrow. More Modern Chemical Techniques identifies some applications of the important chemical techniques in use today that are less well known in schools and colleges and which illustrate how chemistry is using state-of-the-art technology to push back the frontiers of the subject. Examples include: elemental analysis such as atomic absorption spectrometry and inductively coupled plasma techniques; separations including electrophoresis, structure determination (eg x-ray diffraction and optical microscopy); and sampling and sample preparation.

This book provides a comprehensive overview of the current knowledge on the fate and interaction of pharmaceuticals in soil-crop systems. It addresses the principles of their transport, uptake and metabolism and reviews methodologies for their analytical determination. It also discusses ecotoxicological effects arising from their presence and highlights bioremediation approaches for their removal. The use of treated wastewater to irrigate crops is becoming more widespread in regions where freshwater is limited. This practice conserves freshwater resources and contributes to nutrient recycling. However, concerns remain regarding the safety of irrigation with treated wastewater since it contains residues of pharmaceuticals that have survived treatment, which means that soil and fauna are potentially exposed to these xenobiotics. Various pathways govern the fate of pharmaceuticals in crop-soil systems, including soil degradation; formation of non-extractable residues; uptake by soil-dwelling organisms (e.g. earthworms); and uptake, transport, and metabolism in agricultural crops. Investigations into these aspects have only recently been initiated, and there is still a long way to go before a meaningful assessment of the impact of wastewater has been completed.

This book focuses on the characterization of the amorphous phase of polymers, whether they are pure amorphous or semi-crystalline ones, above Tg or below Tg, by studying the relaxation of dipoles and space charges naturally found in their structure after they have been activated by the application of a voltage field. The experimental deconvolution of the relaxation modes responsible for internal motion in the amorphous phase is coupled with a mathematical procedure (Thermal-Windowing Deconvolution-TWD) that leads to the understanding of their coupling characteristics which, it is shown, relate to the state of the material itself, for instance its non-equilibrium state or its internal stress for matter belonging to interfaces between aggregated or dispersed phases. Describes quantitatively the Thermal Stimulated Depolarization techniques of polymer characterization (TSD, TWD), i.e. how to decouple the relaxation modes collectively interacting (interactive coupling) and relate it to the thermodynamic properties of the amorphous phase. Understands the results of depolarization in terms of the new physics of polymer interactions: the Dual-Phase model, here applied to the dipoles-space charge dynamics. Provides a roaster of CASE STUDIES: practical applications of the TSD and TWD characterization techniques to describe coupled molecular motions in resins, medical tissues, wood, blends and block copolymers interfaces, rubbers, can coatings, internal stress in molded parts, etc
