Описание: Recently crystallography and spectroscopy have reached a level of experimental sophistication and theoretical and computational advancements such that it is possible to understand the structure of even the most complex molecular systems, such as, proteins. The modern generation of synchrotrons and the powerful free electron lasers (X-FEL) offer new opportunities and exciting challenges in structural science, but they will require a coordinated approach of complementary methods if they are to achieve maximum impact. Researchers are constantly improving technical and computational methods to accelerate and automate characterisation processes and this is crucial to the fields to be explored in this book. Bringing together world experts in computational, crystallographic, spectroscopic, chemical, biological and numerous characterisation methods, this title will promote new interdisciplinary research and complementary approaches and techniques in the rapidly emerging areas of 'time resolved studies', leading to a greater overall understanding of structural dynamics.
Описание: Experimentalists and theoreticians discuss how new techniques for monitoring photochemical processes can complement each other, address contention and controversy, and propose future research.
Описание: Vibrational biomedical spectroscopy, near field methods and many aspects of associated biophotonics have advanced significantly in recent years. Diagnostic and prognostic tools based on these new technologies have the potential to revolutionise our clinical systems leading to improved patient outcome, more efficient public services and significant economic savings for healthcare providers and society. This meeting brings together scientists researching vibrational spectroscopy and the development of clinically relevant diagnostic tools to discuss the current challenges and emerging opportunities in this field.

Описание: This thesis presents a highly innovative study of the ultrafast structural and vibrational dynamics of hydrated phospholipids, the basic constituents of cell membranes. As a novel approach to the water-phospholipid interface, the author studies phosphate vibrations using the most advanced methods of nonlinear vibrational spectroscopy, including femtosecond two-dimensional infrared spectroscopy. He shows for the first time that the structure of interfacial water undergoes very limited fluctuations on a 300 fs time scale and that the lifetimes of hydrogen bonds with the phospholipid are typically longer than 10 ps. Such properties originate from the steric hindrance of water fluctuations at the interface and the orienting action of strong electric fields from the phospholipid head group dipoles. In an extensive series of additional experiments, the vibrational lifetimes of the different vibrations and the processes of energy dissipation are elucidated in detail.
Описание: Understanding the mechanism of physical, chemical and biological change at the microscopic scale is critical for a broad range of science and technology. A common goal is to develop this understanding to the point where it becomes possible to tailor functionality through material design, or by the application of electric, magnetic or optical fields. Across a broad range of disciplines the scientific community is currently frustrated by its inability to dynamically image matter down to the atomic scale. We can at present only observe relatively slow motion changes to structure, or infer dynamical effects via indirect measurements. Yet many critically important processes evolve on the femtosecond timescale and at the molecular and sub-cellular level requiring nanometre and sub-nanometre scale spatial resolution. The properties of light from newly developing photon sources such as free electron lasers (FELs) are dramatically different from those of storage rings (in terms of spectral brightness), and from conventional lasers (in terms of wavelength range). In the course of the last few years FELs and other sources have emerged as exceptionally exciting tools for new science – for example, solution phase chemistry, enzyme and surface catalysis and DNA photo-induced radiation damage. In this volume the topics covered include: Chemical reaction dynamics; Electron dynamics in atoms, molecules and clusters; Correlated systems, surfaces and catalysis; Nanoscale and bio imaging
Описание: This title will appeal to researchers interested in liquid structuring issues which play a defining role in determining chemical reactivity, transport properties, crystal nucleation, and other physicochemical properties important to engineering and biology.

Описание:
Resolving Spectral Mixtures: With Applications from Ultrafast Time-Resolved Spectroscopy to Superresolution Imaging offers a comprehensive look into the most important models and frameworks essential to resolving the spectral unmixing problem--from multivariate curve resolution and multi-way analysis to Bayesian positive source separation and nonlinear unmixing. Unravelling total spectral data into the contributions from individual unknown components with limited prior information is a complex problem that has attracted continuous interest for almost four decades.
Spectral unmixing is a topic of interest in statistics, chemometrics, signal processing, and image analysis. For decades, researchers from these fields were often unaware of the work in other disciplines due to their different scientific and technical backgrounds and interest in different objects or samples. This led to the development of quite different approaches to solving the same problem. This multi-authored book will bridge the gap between disciplines with contributions from a number of well-known and strongly active chemometric and signal processing research groups.
Among chemists, multivariate curve resolution methods are preferred to extract information about the nature, amount, and location in time (process) and space (imaging and microscopy) of chemical constituents in complex samples. In signal processing, assumptions are usually around statistical independence of the extracted components. However, the chapters include the complexity of the spectral data to be unmixed as well as dimensionality and size of the data sets. Advanced spectroscopy is the key thread linking the different chapters. Applications cover a large part of the electromagnetic spectrum. Time-resolution ranges from femtosecond to second in process spectroscopy and spatial resolution covers the submicronic to macroscopic scale in hyperspectral imaging.
Описание: This Faraday Discussions volume addresses the challenges in both fundamental and applied nanoelectrochemistry, where new concepts and new knowledge play key roles.
