From a stunning new voice in hard science fiction comes the thrilling story of one woman’s quest to wrest truth from chaos, love from violence, and reality from illusion in a post-human universe of emergent AIs, genetic constructs, and illegal wetware. . . . UN Peacekeeper Major Catherine Li has made thirty-seven faster-than-light jumps in her lifetime—and has probably forgotten more than most people remember. But that’s what backup hard drives are for. And Li should know; she’s been hacking her memory for fifteen years in order to pass as human. But no memory upgrade can prepare Li for what she finds on Compson’s World: a mining colony she once called home and to which she is sent after a botched raid puts her on the bad side of the powers that be. A dead physicist who just happens to be her cloned twin. A missing dataset that could change the interstellar balance of power and turn a cold war hot. And a mining “accident” that is starting to look more and more like murder. . . . Suddenly Li is chasing a killer in an alien world miles underground where everyone has a secret. And one wrong turn in streamspace, one misstep in the dark alleys of blackmarket tech and interstellar espionage, one risky hookup with an AI could literally blow her mind.

It has long been recognized that metal spin states play a central role in the reactivity of important biomolecules, in industrial catalysis and in spin crossover compounds. As the fields of inorganic chemistry and catalysis move towards the use of cheap, non-toxic first row transition metals, it is essential to understand the important role of spin states in influencing molecular structure, bonding and reactivity. Spin States in Biochemistry and Inorganic Chemistry provides a complete picture on the importance of spin states for reactivity in biochemistry and inorganic chemistry, presenting both theoretical and experimental perspectives. The successes and pitfalls of theoretical methods such as DFT, ligand-field theory and coupled cluster theory are discussed, and these methods are applied in studies throughout the book. Important spectroscopic techniques to determine spin states in transition metal complexes and proteins are explained, and the use of NMR for the analysis of spin densities is described. Topics covered include: DFT and ab initio wavefunction approaches to spin states Experimental techniques for determining spin states Molecular discovery in spin crossover Multiple spin state scenarios in organometallic reactivity and gas phase reactions Transition-metal complexes involving redox non-innocent ligands Polynuclear iron sulfur clusters Molecular magnetism NMR analysis of spin densities This book is a valuable reference for researchers working in bioinorganic and inorganic chemistry, computational chemistry, organometallic chemistry, catalysis, spin-crossover materials, materials science, biophysics and pharmaceutical chemistry.

In this stunning follow-up to the critically acclaimed novel Spin State, Chris Moriarty depicts a grim future in which the final frontier may well be extinction. For as far-flung planets are terraformed and Earth’s age-old conflicts are contracted out to AIs, humanity is losing the only war that counts: the war for survival. Call Arkady a clone with a conscience. Or call him a traitor. A member of the space-faring Syndicates, Arkady has defected to Israel with a hot commodity: a genetic weapon powerful enough to wipe out humanity. But Israel’s not buying it. They’re selling it—and Arkady—to the highest bidder. As the auction heats up, the Artificial Life Emancipation Front sends in Major Catherine Li. Already drummed out of the Peacekeepers for “war crimes,” Li has now literally hooked up with an AI who has lived many lifetimes and shunted through many bodies. And while they each have their own definition of victory, together they have only one chance at survival. . . .

The purpose of this collective book is to present a non-exhaustive survey of sp- related phenomena in semiconductors with a focus on recent research. In some sense it may be regarded as an updated version of theOpticalOrientation book, which was entirely devoted to spin physics in bulk semiconductors. During the 24 years that have elapsed, we have witnessed, on the one hand, an extraordinary development in the wonderful semiconductor physics in two dim- sions with the accompanying revolutionary applications. On the other hand, during the last maybe 15 years there was a strong revival in the interest in spin phen- ena, in particular in low-dimensional semiconductor structures. While in the 1970s and 1980s the entire world population of researchers in the ?eld never exceeded 20 persons, now it can be counted by the hundreds and the number of publications by the thousands. This explosive growth is stimulated, to a large extent, by the hopes that the electron and/or nuclear spins in a semiconductor will help to accomplish the dream of factorizing large numbers by quantum computing and eventually to develop a new spin-based electronics, or “spintronics”. Whether any of this will happen or not, still remains to be seen. Anyway, these ideas have resulted in a large body of interesting and exciting research, which is a good thing by itself. The ?eld of spin physics in semiconductors is extremely rich and interesting with many spectacular effects in optics and transport.

The phenomenon of spin-crossover has a large impact on the physical properties of a solid material, including its colour, magnetic moment, and electrical resistance. Some materials also show a structural phase change during the transition. Several practical applications of spin-crossover materials have been demonstrated including display and memory devices, electrical and electroluminescent devices, and MRI contrast agents. Switchable liquid crystals, nanoparticles, and thin films of spin-crossover materials have also been achieved. Spin-Crossover Materials: Properties and Applications presents a comprehensivesurvey of recent developments in spin-crossover research, highlighting the multidisciplinary nature of this rapidly expanding field. Following an introductory chapter which describes the spin-crossover phenomenon and historical development of the field, the book goes on to cover a wide range of topics including Spin-crossover in mononuclear, polynuclear and polymeric complexes Structure: function relationships in molecular spin-crossover materials Charge-transfer-induced spin-transitions Reversible spin-pairing in crystalline organic radicals Spin-state switching in solution Spin-crossover compounds in multifunctional switchable materials and nanotechnology Physical and theoretical methods for studying spin-crossover materials Spin-Crossover Materials: Properties and Applications is a valuable resource for academic researchers working in the field of spin-crossover materials and topics related to crystal engineering, solid state chemistry and physics, and molecular materials. Postgraduate students will also find this book useful as a comprehensive introduction to the field.

Sometimes a ghost of a chance is all you get. Award-winning author Chris Moriarty returns to a dazzling cyber-noir far future in this gritty, high-stakes thriller where the only rule is “Evolve . . . or die.” The Age of Man is ending. The UN’s sprawling interstellar empire is failing as its quantum teleportation network collapses, turning once-viable colonies into doomed island outposts. Humanity’s only hope of survival is the Drift: a mysterious region of space where faster-than-light travel—or something far stranger—seems possible. As mercenaries and pirates flock to the Drift, the cold war between the human-led UN and the clone-dominated Syndicates heats up. Whoever controls the Drift will chart the future course of human evolution—and no one wants to be left behind in a universe where the price of failure is extinction. When the AI called Cohen ventures into the Drift, he dies—allegedly by his own hand—and his consciousness is scattered across the cosmos. Some of his ghosts are still self-aware. Some are insane. And one of them hides a secret worth killing for. Enter Major Catherine Li, Cohen’s human (well, partly human) lover, who embarks on a desperate search to solve the mystery of Cohen’s death—and put him back together. But Li isn’t the only one interested in Cohen’s ghosts. Astrid Avery, a by-the-book UN navy captain, is on the hunt. So is William Llewellyn, a pirate who has one of the ghosts in his head, which is slowly eating him alive. Even the ghosts have their own agendas. And lurking behind them all is a pitiless enemy who will stop at nothing to make sure the dead don’t walk again. Praise for Ghost Spin “Complexity is the watchword here, of thought, idea, narrative, character and plot. . . . Highly rewarding.”—Kirkus Reviews “Rewarding . . . The adaptations humans make to survive in the hostile environments of other worlds, a galaxy teetering on the edge of singularity . . . are genuinely visionary.”—Publishers Weekly “This stand-along ‘spin-off’ offers a compelling tale of adventure/suspense blended with cybernoir and high-tech sf.”—Library Journal “An excellent read: gripping, fast-paced, provocative and handsome.”—Tordotcom “A brilliant mix of space opera, cyberpunk, and just plain great writing, Moriarty’s work is some of the most impressive in science fiction today.”—SFRevu

These volumes contain 365 of the 505 papers presented at the VUV-11 Conference, held at Rikkyo University, Tokyo, from August 27th to September 1st 1995. The papers are divided into three sections: atomic and molecular spectroscopy, solid state spectroscopy and instrumentation and technological applications. New aspects presented were both quantitative and qualitative improvements in fluorescence spectroscopy and magnetic circular dichroism measurements. The fluorescence data are complementary to those of photoemission in a sense but they appear to open up a new method to analyze the optical excitation and relaxation processes. The application of magnetic circular dichroism has proved to be useful not only in analyzing the electronic structures of magnetic materials but also in practical applications to material engineering as found in experiments combined with photoelectron microscopy. Excellent developments in applications are only found in the field of surface photochemistry, where the technique of etching using VUV light has been appreciably refined. Although the majority of distinctive scientific features in the VUV-11 Conference have been brought about by the application of synchrotron radiation, experiments using a different type of light source appear to have progressed steadily. This is evident in the studies of plasma radiation.

In this collection, the author has compiled a set of his papers representing some of the highlights of materials chemistry. It features a section on oxidic materials, which includes high-temperature superconductivity, colossal magnetoresistance, electronic phase separation and multiferroics. The author has also included novel methods for making gallium nitride, boron nitride and such materials, by using precursors and the urea decomposition route. Moreover, there is a section dealing with open-framework and hybrid materials of which the latter has a great future since one can make use of the rigidity of inorganic structures and the functionality and flexibility of the organic residues to design materials with novel properties.
