Photoelectrochemical Water-splitting: Standards, Experimental Methods, and Protocols
by Eric Miller Huyen Dinh Zhebo ChenThis book outlines many of the techniques involved in materials development and characterization for photoelectrochemical (PEC) - for example, proper metrics for describing material performance, how to assemble testing cells and prepare materials for assessment of their properties, and how to perform the experimental measurements needed to achieve reliable results towards better scientific understanding. For each technique, proper procedure, benefits, limitations, and data interpretation are discussed. Consolidating this information in a short, accessible, and easy to read reference guide will allow researchers to more rapidly immerse themselves into PEC research and also better compare their results against those of other researchers to better advance materials development. This book serves as a "how-to" guide for researchers engaged in or interested in engaging in the field of photoelectrochemical (PEC) water splitting. PEC water splitting is a rapidly growing field of research in which the goal is to develop materials which can absorb the energy from sunlight to drive electrochemical hydrogen production from the splitting of water. The substantial complexity in the scientific understanding and experimental protocols needed to sufficiently pursue accurate and reliable materials development means that a large need exists to consolidate and standardize the most common methods utilized by researchers in this field.
Photoelectron Spectroscopy: Bulk and Surface Electronic Structures
by Akira Sekiyama Shigemasa SugaPhotoelectron spectroscopy is now becoming more and more required to investigate electronic structures of various solid materials in the bulk, on surfaces as well as at buried interfaces. The energy resolution was much improved in the last decade down to 1 meV in the low photon energy region. Now this technique is available from a few eV up to 10 keV by use of lasers, electron cyclotron resonance lamps in addition to synchrotron radiation and X-ray tubes. High resolution angle resolved photoelectron spectroscopy (ARPES) is now widely applied to band mapping of materials. It attracts a wide attention from both fundamental science and material engineering. Studies of the dynamics of excited states are feasible by time of flight spectroscopy with fully utilizing the pulse structures of synchrotron radiation as well as lasers including the free electron lasers (FEL). Spin resolved studies also made dramatic progress by using higher efficiency spin detectors and two dimensional spin detectors. Polarization dependent measurements in the whole photon energy spectrum of the spectra provide useful information on the symmetry of orbitals. The book deals with the fundamental concepts and approaches for the application of this technique to materials studies. Complementary techniques such as inverse photoemission, photoelectron diffraction, photon spectroscopy including infrared and X-ray and scanning tunneling spectroscopy are presented. This book provides not only a wide scope of photoelectron spectroscopy of solids but also extends our understanding of electronic structures beyond photoelectron spectroscopy.
Photoelectron-Ion Correlation in Photoionization of a Hydrogen Molecule and Molecule-Photon Dynamics in a Cavity (Springer Theses)
by Takanori NishiThis book presents the latest theoretical studies giving new predictions and interpretations on the quantum correlation in molecular dynamics induced by ultrashort laser pulses. The author quantifies the amount of correlation in terms of entanglement by employing methods developed in quantum information science, in particular applied to the photoionization of a hydrogen molecule. It is also revealed that the photoelectron–ion correlation affects the vibrational dynamics of the molecular ion and induces the attosecond-level time delay in the molecular vibration. Furthermore, the book also presents how molecular vibration can couple to photons in a plasmoic nanocavity.Physicists and chemists interested in the ultrafast molecular dynamics would be the most relevant readers. They can learn how we can employ the quantum-information-science tools to understand the correlation in the molecular dynamics and why we should consider the correlation between the photoelectron and the molecular ion to describe the ion’s dynamics. They can also learn how to treat a molecule coupled to photons in a nanocavity. All the topics are related to the state-of-the-art experiments, and so, it is important to publish these results to enhance the understanding and to induce new experiments to confirm the theory presented.

Photoemission from Optoelectronic Materials and their Nanostructures
by Debashis De Kamakhya Prasad Ghatak Sitangshu BhattacharyaIn recent years, with the advent of fine line lithographical methods, molecular beam epitaxy, organometallic vapour phase epitaxy and other experimental techniques, low dimensional structures having quantum confinement in one, two and three dimensions (such as ultrathin films, inversion layers, accumulation layers, quantum well superlattices, quantum well wires, quantum wires superlattices, magneto-size quantizations, and quantum dots) have attracted much attention not only for their potential in uncovering new phenomena in nanoscience and technology, but also for their interesting applications in the areas of quantum effect devices. In ultrathin films, the restriction of the motion of the carriers in the direction normal to the film leads to the quantum size effect and such systems find extensive applications in quantum well lasers, field effect transistors, high speed digital networks and also in other quantum effect devices. In quantum well wires, the carriers are quantized in two transverse directions and only one-dimensional motion of the carriers is allowed.

Photofunctionalization of Molecular Switch Based on Pyrimidine Ring Rotation in Copper Complexes
by Michihiro NishikawaThis book provides a detailed description of photofunctionalization of molecular switch based on pyrimidine ring rotational isomerization in copper complexes bearing two bidentate ligands. The most important features of this work focus on the properties associated with the rotational isomerization based on the two possible coordination geometries at the copper center derived from two nitrogen atoms on the unsymmetrically substituted pyrimidine ring. The functions of systems such as dual emission and redox potential switching based on photo-driven rotation will be of particular interest to readers. Both the functions and the procedures for proving these phenomena are beneficial for the development of more functionalized systems based on material science, molecular science, nanoscience, nanotechnology, electrochemistry, photochemistry, coordination chemistry, physical chemistry, and related disciplines. The finding elucidated here holds promise for handling the photoprocesses of metal complexes, valid for both applications and novel properties. This system is expected make it possible to extract an electrochemical potential response from molecular switches, aiming to simulate the five senses of human beings at a single molecular level.

Photography and Other Media in the Nineteenth Century
by Simone Natale Nicoletta LeonardiIn this volume, leading scholars of photography and media examine photography’s vital role in the evolution of media and communication in the nineteenth century.In the first half of the nineteenth century, the introduction of telegraphy, the development of a cheaper and more reliable postal service, the rise of the mass-circulation press, and the emergence of the railway dramatically changed the way people communicated and experienced time and space. Concurrently, photography developed as a medium that changed how images were produced and circulated. Yet, for the most part, photography of the era is studied outside the field of media history. The contributors to this volume challenge those established disciplinary boundaries as they programmatically explore the intersections of photography and “new media” during a period of fast-paced change. Their essays look at the emergence and early history of photography in the context of broader changes in the history of communications; the role of the nascent photographic press in photography’s infancy; and the development of photographic techniques as part of a broader media culture that included the mass-consumed novel, sound recording, and cinema.Featuring essays by noteworthy historians in photography and media history, this discipline-shifting examination of the communication revolution of the nineteenth century is an essential addition to the field of media studies.In addition to the editors, contributors to this volume are Geoffrey Batchen, Geoffrey Belknap, Lynn Berger, Jan von Brevern, Anthony Enns, André Gaudreault, Lisa Gitelman, David Henkin, Erkki Huhtamo, Philippe Marion, Peppino Ortoleva, Steffen Siegel, Richard Taws, and Kim Timby.

Photon Management Assisted by Surface Waves on Photonic Crystals
by Angelo AngeliniThis book illustrates original pathways to manipulate light at the nanoscale by means of surface electromagnetic waves (here, Bloch surface waves, BSWs) on planar dielectric multilayers, also known as one-dimensional photonic crystals. This approach is particularly valuable as it represents an effective alternative to the widely exploited surface plasmon paradigm. After a brief overview on the fundamentals of BSWs, several significant applications of BSW-sustaining structures are described. Particular consideration is given to the propagation, guiding, and diffraction of BSW-coupled radiation. Further, the interaction of organic emitters with BSWs on planar and corrugated multilayers is investigated, including fluorescence beaming in free space. To provide greater insight into sensing applications, an illustrative example of fluorescent microarray-based detection is presented. The book is intended for scientists and researchers working on photon management opportunities in fields such as biosensing, optical circuitry, and lighting.
