Processes” is a commonly used term to describe engineered systems such as oil refineries, polymer production plants, and pharmaceutical manufacturing processes that serve a commercial and societal purpose. However, the term can also capture the underlying processes that drive the behavior of complex natural systems such as communities of different organisms in the environment and networked collections of neurons in the human brain. This book provides a representative overview of current challenges and recent advances in the broadly-defined “processes” field. Contributions from leading researchers in the field are conveniently ordered according to five applications domains: chemical systems, biological systems, materials processes, computational methods, and other related topics. The 19 contributions demonstrate the broad range of application domains within the process field, including fluid flow systems, fuel gases, chemical production, polymer manufacturing, food processing, protein synthesis and separation, pharmaceutical production, and water systems. This collection shows that “processes” remain a vibrant area of research, and continued advances in the field can be expected to have a positive impact on our economy, environment, and quality of life.

"Soil Systems is a new journal devoted to publishing articles focused on biological, chemical, and physical processes operating within soils and sediments. We are particularly interested in studies or review articles that examine (or describe) coupled processes operating within these complex media that control element cycling. Processes that impact on retention and release, transport, and microbial interactions in soils are also of interest"--About, viewed March 27, 2020.

This OECD Emission Scenario Document (ESD) provides information on the sources, use patterns, and potential release pathways of chemicals used in the radiation curable products industry, specifically during application of radiation curable coatings, inks, and adhesives. The document focuses primarily on ultraviolet (UV) and electron beam (EB) curable products and presents standard approaches for estimating the environmental releases of and occupational exposures to components and additives used in radiation curable products.

This Special Issue of Atmosphere, "Atmospheric Aqueous-Phase Chemistry", comprises ten original articles dealing with different aspects of chemistry in atmospheric liquid water. Liquid water in cloud and fog droplets and in moist aerosol particles is ubiquitous in the atmosphere. Dissolved species from the soluble aerosol fraction, as well as soluble trace gases, undergo chemical reactions in the aqueous phase via different mechanisms, usually yielding different products from those in the gas phase. In addition to their different reactivity, the chemical species solubility determines their fate in the atmosphere, i.e., their involvement in gas-phase or aqueous-phase chemistry. The articles of this Special Issue can be divided into three groups: (i) the first is mostly based on field measurements and/or combined field and modeling studies giving insights into the chemical characterization of different atmospheric liquid water samples from various environments; (ii) the second group is focused on studies of aqueous-phase reactivity of some important atmospheric organic compounds; and (iii) the final group comprises articles based on predictive modeling and/or combined modeling and laboratory studies providing insight into aqueous secondary organic aerosol (SOA) formation.

This book offers a broad understanding of bioethanol production from sugarcane, although a few other substrates, except corn, will also be mentioned. The 10 chapters are grouped in five sections. The Fuel Ethanol Production from Sugarcane in Brazil section consists of two chapters dealing with the first-generation ethanol Brazilian industrial process. The Strategies for Sugarcane Bagasse Pretreatment section deals with emerging physicochemical methods for biomass pretreatment, and the non-conventional biomass source for lignocellulosic ethanol production addresses the potential of weed biomass as alternative feedstock. In the Recent Approaches for Increasing Fermentation Efficiency of Lignocellulosic Ethanol section, potential and research progress using thermophile bacteria and yeasts is presented, taking advantage of microorganisms involved in consolidating or simultaneous hydrolysis and fermentation processes. Finally, the Recent Advances in Ethanol Fermentation section presents the use of cold plasma and hydrostatic pressure to increase ethanol production efficiency. Also in this section the use of metabolic-engineered autotrophic cyanobacteria to produce ethanol from carbon dioxide is mentioned.
