Catalyst deactivation, the loss over time of catalytic activity and/or selectivity, is a problem of great and continuing concern in the practice of industrial catalytic processes. Costs to industry for catalyst replacement and process shutdown total tens of billions of dollars per year. While catalyst deactivation is inevitable for most processes, some of its immediate, drastic consequences may be avoided, postponed, or even reversed. Accordingly, there is considerable motivation to better understand catalyst decay and regeneration. Indeed, the science of catalyst deactivation and...

The degradation of air quality by the release of volatile organic compounds (VOC) into the air particularly harms human health and our environment. Regulation of outdoor VOC emissions are required to prevent the formation of ground-level ozone, which is principally responsible for photochemical smog. Indoor emissions of VOC have been the subject of recent consideration from many governments around the world because of the adverse impact of VOC on the health of people exposed to them.

Heterogeneous catalytic oxidation is regarded as the most promising technology to control VOC...

Mercury is a serious environmental toxin that is distributed globally by large-scale atmospheric circulations. The chapters in this book cover measurements of speciated atmospheric mercury, regional modeling, continental-scale distributions across the U.S. and Canada, large-scale distributions in the free troposphere, and changes in wet deposition across the U.S. The diverse topics give snap-shots of current research areas in atmospheric mercury and some insight into policy issues in Europe. Together, the work demonstrates the complexity of atmospheric mercury and provides aspects on...

The present printed edition of the Special Issue "Surface Chemistry and Catalysis" published in Catalysts aims to cover some of the recent advances in the field of heterogeneous catalysis that can be obtained by means of advanced characterization techniques, computational calculations and time-resolved methods, with particular emphasis on structure-activity relationships (SARs). It consists of 14 high-quality theoretical and experimental studies on various aspects on catalysis, involving the electrochemical promotion in catalysis, H₂O dissociation, H₂...

In a dedicated Special Issue, the journal Polymers has compiled papers on the current trends and research directions within the preparation, characterization and application of polymer-based composite materials in electrical engineering applications. In recent times, this type of material has evolved to become one of the most thoroughly investigated materials, stimulated by the demand for the resource-efficient assembly of generators, transformers, communication devices, etc. Novel composites are to be used as insulating materials with high thermal conductivity and excellent...

Medical Microbiology is an excellent and easy-to-use textbook which explains the roles of microorganisms in human health and illness. Written in a clear and engaging manner, the book provides an overview of pathogenic organisms, their diagnosis and treatment tools as well as the molecular mechanisms of host-pathogen interactions and antimicrobial drug resistance.
