Energy release to solid interfaces following chemical reactions is ubiquitous in a vast range of phenomena. Energy dissipation and dynamical disorder (surface entropy), surface friction and molecular diffusion control the rates of heterogeneous catalytic reactions, the efficiency of novel technology, lubrication as well as materials growth including self-assembly and nano-structures. Yet we understand little about the underlying nature of these mechanisms. Fundamentally, energy dissipation including interactions with phonons and electron-hole pairs determines the lifetime of molecular vibrations and rotations as well as the decoherence rate of quantum states. These processes form a central point for many aspects in physical chemistry, are embedded in the mechanisms that control surface dynamical processes and are critical factors in catalysis. They are equally relevant for physicochemical processes in the Earth's atmosphere and astrochemistry occurring on cosmic dust grains.
Famous for its alpine bird specialities such as Wallcreeper, Alpine Accentor, Alpine Chough and Nutcracker, Switzerland has much to offer any birder. This is a guide to 45 of the best birdwatching sites with species information, suggested times to visit and details on transport and accommodation. Each site has a map with itineraries indicated so that no time is wasted once there.

Each of the essays in this volume, originally published in 1970, touches upon a historical theme which Herbert Butterfield illuminated. It covers a wide range of topics from music and relgion in modern European history to the scientific revolution of the 17th century.
Chemical reactions and growth processes on surfaces depend on the diffusion and re-orientation of the adsorbate molecules. A fundamental understanding of the forces guiding surface motion is thus of utmost importance for the advancement of many fields of science and technology. To date, our understanding of the principles underlying surface dynamics remains extremely limited, due to the difficulties involved in measuring these processes experimentally. The helium-3 spin-echo (HeSE) technique is uniquely capable of probing such surface dynamical phenomena. The present thesis extends the field of application of HeSE from atomic and small molecular systems to more complex systems. Improvements to the supersonic helium beam source, a key component of the spectrometer, as well as a detailed investigation of a range of five-membered aromatic adsorbate species are presented. The thesis provides a comprehensive description of many aspects of the HeSE method - instrumentation, measurement and data analysis - and as such offers a valuable introduction for newcomers to the field.
Following the British withdrawal in 1971, the Gulf Region entered a heady period of political restructuring, awash with oil money that helped fund national aspirations. Infrastructure investment became a central part of the region's nation-building initiatives and fueled strong competition. Without its neighbours' oil fields, infrastructure and territorial development became particularly vital to Dubai. This book provides a unique and detailed understanding of Dubai urbanism by demonstrating that cumulative programmatic intensification and scalar amplification of its large-scale infrastructural components guided its metropolitan growth and generated a territorial organization logic that outs...
