Photochemical reactions have tremendous scientific importance, ranging from photosynthesis to atmospheric reactions, and technologies such as sensors or displays. Due to the intrinsic complexity of photochemical reactions, they remain the least understood type of chemical process. Nonadiabatic dynamics, ultrafast time-scales, quantum effects and conical intersections are known to be important, but a detailed comprehension remains elusive. However, new experimental techniques capable of monitoring photochemical processes in unprecedented detail are appearing. Many of these techniques are being developed by research communities not traditionally concerned with photochemistry, but provide an opportunity to shed new light on photochemical dynamics. This Faraday Discussion brings together experimentalists and theoreticians working from different perspectives in the field. It provides the opportunity to identify how new techniques can complement each other, to address contention and controversy, and to propose future research.

Combining the basic concepts of photocatalysis with the synthesis of new catalysts, reactor and reaction engineering, and exploring the numerous important applications of photocatalysis, these books provide a comprehensive resource on the topic. Photocatalysis: Fundamentals and Perspectives introduces the fundamental aspects of photocatalysis before exploring the theory and experimental studies of charge carrier dynamics. Photocatalysis: Applications discusses photocatalytic processes applied to a wide range of areas, from the treatment of water and air; to photocatalysis in food packaging and biomedical and medical applications. Together these books provide a complete overview to photocatalysis. Researchers new to this field can learn the first principles, whilst experienced researchers can gain further information about applications of photocatalysis beyond their area of expertise.

The purpose of this volume is to trace the development of the
theoretical understanding of quark-gluon plasma, both in terms of the
equation of state and thermal correlation functions and in terms of
its manifestation in high energy nuclear collisions. Who among us has
not wondered how tall a mountain is on a neutron star, what happens
when matter is heated and compressed to higher and higher densities,
what happens when an object falls into a black hole, or what happened
eons ago in the early universe? The study of quark-gluon plasma is
related in one way or another to these and other thought provoking
questions. Oftentimes the most eloquent exposition is given in the
original papers. To this end a selection is made of what are the
most important pioneering papers in this field. The early 1950s was
an era when high energy multiparticle production in cosmic ray
interactions attracted the attention of some of the brightest minds
in physics, and so it should be no surprise that the first reprinted
papers deal with the introduction of statistical models of particle
production. The quark model arose in the 1960s, while QCD as such
was recognized as the theory of the strong interactions in the
1970's. The behavior of matter at high temperatures and supranuclear
densities became of wide interest in the nuclear and particle physics
communities starting in the 1970s, which is when the concept of
quark-gluon plasma became established. The history of the field has
been traced up to the early 1990s. There are three reasons for
stopping at that point in time. First, most of the key theoretical
concepts and formalisms arose before 1993, although many of them
continue to be developed today and hopefully well into the future.
Second, papers written after 1992 are much more readily available
than those writen before due to the advent of the World Wide Web and
its electronic preprint databases and journals. Finally, in making
this collection of reprints available as hardcopy one is limited in
the number of pages, and some papers in the present selection should
have been deleted in order to make room for post-1993 papers. For the
same reason the subject focus must of necessity be limited, which
means that in this reprint collection two wide subject areas are not
addressed: the behavior of nuclear matter under extreme conditions
is not reported, nor is quark matter in neutron stars. The broad
categories into which the material has been placed, reflect the
diverse studies of quark-gluon plasma and its manifestation. They
are: phase-space models of particle production, perturbative QCD
plasma, lattice gauge theory, fluid dynamics and flow, strangeness,
heavy flavor (charm), electromagnetic signals, parton cascade and
minijets, parton energy loss and jet quenching, Hanbury Brown--Twiss
(HBT) interferometry, disoriented chiral condensates, phase
transition dynamics and cosmology, and color superconductivity. Each
chapter is prefaced by an introduction, which contains a list of
significant papers which is more complete than the reprinted papers,
though by no means exhaustive. It also contains citations to most
relevant papers published up to the date of completion of this volume
(fall 2002). It is hoped that the short reviews will help bring the
reader up to date on the latest developments. The selection of
papers cited in each chapter, and in particular the ones selected for
reprinting, is solely the responsibility of the Editors. It is based
on their best judgement and experience in this field dating back to
the mid-1970s. In order to be reprinted a paper must have been
pioneering in the sense of originality and impact on the field.
Generally they have been cited over a hundred times by other papers
published in refereed journals. The final selection was reviewed and
discussed among the Editors repeatedly. Just because a paper is not
included does not mean they do not know of it or do not have a high
regard for it. All of the papers cited or reprinted are original
research contributions. There are three other types of publications
listed. The first is a compilation of books. The second is a list
of reviews, many of which contain a significant amount of original
material. The third is a list of the proceedings of the series of
Quark Matter meetings, the primary series of international
conferences in this field that is attended by both theorists and
experimentalists.

Over the past few decades, the excitation and ionization of atmospheric gases has become an area of intense research. A large amount of data have been accumulated concerning the various elementary processes which occur when photons, electrons and ions collide with atoms and molecules. This scattered information has now been collected in a handbook for the first time, and the authors give a critical analysis of relevant data.
This book is a comprehensive and detailed study of the available information and is distinguished by the following outstanding features: the consideration of a large number of atmospheric constituents, including H DEGREESO2, H, N DEGREESO2, N, O DEGREESO2, O, CO, CO DEGREESO2, H DEGREESO2O, HCl and some hydrocarbons the maximum number of space particles, including magnetospheric particles, are considered as projectiles: photons, electrons, hydrogen atoms, protons and helium ionsthe energy range under study corresponds to the real spectrum of cosmic fluxes, from threshold values for elementary processes up to several thousand keV the recommended values of cross sections, obtained from analysis of the available experimental data, are given in the handbook and their accuracy is estimated.
These features make the handbook particularly valuable to specialists in the aeronomy of planets, comets and active perturbations, as well as to experimentalists and theoreticians working in the fields of plasma physics, atomic and molecular physics, physics of the upper atmosphere, chemical physics, o

The authors expound on non-traditional phenomena for transfer theory, which are nevertheless of considerable interest in wave measurements, and bring the advances of transfer theory as close as possible to the practical needs of those working in all areas of wave physics. The book opens with a historical overview of the topic, then moves on to examine the phenomenological theory of radiative transport, blending traditional theory with original ideas. The transport equation is derived from first principles, and the ensuing discussion of the diffraction content of the transport equation and non-classical radiometry is illustrated by practical examples from various fields of physics. Popular techniques of solving the transport equation are discussed, paying particular attention to wave physics and computing the coherence function. The book also examines various problems which are no longer covered by the traditional radiative transfer theory, such as enhanced backscattering and weak localization phenomena, nonlinear transport problems and kinetic equations for waves. This monograph bridges the gap between the simple power balance description in radiative transfer theory and modern coherence theory. It will be of interest to researchers and professionals working across a wide range of fields from optics, acoustics and radar theory to astrophysics, radioastronomy and remote sensing, as well as to students in these areas.

Laser photoelectron emission not only allows investigation of interfaces between electrodes and solution, but also provides a method for fast generation of intermediate species in the vicinity of the interface and so permits study of their electrode reactions. Laser Electrochemistry of Intermediates presents the first-ever comprehensive review of this important phenomenon and its electrochemical applications.
The book explores how the innovative method of laser electron emission from metal electrodes resolves two fundamental problems inherent in current methods of intermediate species (IS) generation and detection: difficulty generating IS quickly in the vicinity of the electrode surface and low IS surface concentration. In addition, for the first time, quasi-free and solvated electrons, hydrogen atoms, simple organic and inorganic radicals, and ions with anomalous valence are systematically studied.
Laser Electrochemistry of Intermediates incorporates a unique, two-pronged analytical approach. First, the authors consider the kinetics and thermodynamics of the processes based on the participation of IS in its one-electron stages, thus allowing the assignment of real physical meaning to the electrochemical measurables. Second, they consider electrode reactions side by side with homogeneous reactions of electron transfer, facilitating understanding of the universal theory of electron transfer reactions in polar media as well as the peculiarities of these reactions occurring in the interface between electrode and solution.
