Buch. Zustand: Neu. Neuware - This book offers a unique perspective of the impact of scanning probe microscopies on our understanding of the chemistry of the surface at the nanoscale. Research oriented, with the concepts gleaned from Scanning Tunnelling Microscopy being related to the more established and accepted views in surface chemistry and catalysis the authors have addresses the question 'How do the models based on classical spectroscopic and kinetic studies stand up to scrutiny at the atom - resolved level '. In taking this approach the reader, new to the field of surface chemistry, should be able to obtain a perspective on how the evidence from STM confirms or questions long standing tenets. An emphasis is given to 'how did we get to where we are now' and a large number of figures from the literature are included along with suggestions for further reading. Topics discussed include: - the dynamics of oxygen chemisorption at metal surfaces - control of oxygen states and surface reconstruction - dissociative chemisorption of diatomic and hydrocarbon molecules - nanoparticles and chemical reactivity - STM at high pressures - structural studies of sulfur containing molecules and molecular templating This book will appeal to all those who wish to become familiar with the contribution Scanning Tunnelling Microscopy has made to the understanding of the field of surface chemistry and heterogeneous catalysis and also to those who are new to catalysis, a fascinating and important area of chemistry.

Buch. Zustand: Neu. Neuware - Faraday Discussions 137 This volume focuses on micron sized particles, with emphasis on particles spanning a size range of 100 nm to 100 m, dispersed in a gaseous or liquid medium. The role of microparticles in complex environments is poorly understood and techniques to study the chemical and physical dynamics of microparticles are continually developing. Researchers can now characterise the size, composition and morphology of microparticles and trap and manipulate single particles. Work is presented in the following areas: Optical spectroscopy of microparticles; elastic scattering, Raman scattering, fluorescence spectroscopy, non-linear spectroscopy Chemical dynamics of microparticles; including chemistry relevant to the atmosphere, soft condensed matter, dusty plasmas, combustion processes Physical dynamics of microparticles; including phase transformation, size morphology, interparticle interactions New techniques for manipulating and characterising microparticles; optical and electrodynamic methods, new analytical techniques.
