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 regeneration has been developing rapidly as evidenced by the considerable literature addressing this topic, including 21,000 journal articles, presentations, reports, reviews, and books; and more than 29,000 patents for the period of 1980 to 2012. This developing science provides the foundation for continuing, substantial improvements in the efficiency and economics of catalytic processes through development of catalyst deactivation models, more stable catalysts, and regeneration processes.This special issue focuses on recent advances in catalyst deactivation and regeneration, including advances in (1) scientific understanding of mechanisms; (2) development of improved methods and tools for investigation; and (3) more robust models of deactivation and regeneration.

Vitamin D research has expanded greatly over the last 10 years, with a more than two-fold increase in annual publications listed in Pubmed with the key word ‘vitamin D’ from 1675 in 2005 to 3953 in 2014. Part of this increase is due to research showing that vitamin D deficiency is associated with a wide range of diseases and health outcomes. Until the 1980s, the primary focus of vitamin D research (in combination with calcium supplementation) was on bone diseases. Since then, observational studies have linked vitamin D deficiency with increased risk of many diseases: both acute and chronic. This book contains publications on several of these disease groups linked to vitamin D deficiency.
