Evaporative heat and mass transfer with solubility driven solidification of aqueous droplet flows
… water decomposition using a copper-chlorine cycle consists of a series of chemical reactions that split water into hydrogen and oxygen. This is accomplished through reactions involving intermediate copper and chlorine compounds, which act as catalysts that are recycled in the …

Theoretical and experimental studies of heterogeneous chemical processes leading to stratospheric ozone depletion
… chemists, because such reactions yield "active" chlorine compounds that are readily photolyzed to yield radicals responsible for the annual destruction of polar stratospheric ozone. Using molecular-orbital and density-functional-based computational methods that are extensively validated, partial …

Cloth Filter for Disaster Relief Water Treatment
… sachets, which contain coagulant and chlorine compounds. Following treatment with PŪR<sup>®</sup>, treated water in the waterbag is flowed through an outlet port to a filter, primarily for parasitic cyst removal. Currently, the commercial version of the waterbag uses an effective but …

The Effect of Chlorine and Chloramines on the Viability and Activity of Nitrifying Bacteria
… nitrification events, including optimizing the chlorine-to-ammonia ratio, maintaining chloramine residual throughout the distribution system, controlling pH, and temporal switching to free chlorination. Annual or semi-annual application of free chlorination is practiced by 23% of chloraminating …

Measurement and deduction of emissions of short-lived atmospheric organo-chloride compounds
… organics. Most previous studies of reactive chlorine compounds have focused solely on quantifying their ambient levels in urban and rural regions. However, for many of these organo-chlorine molecules a detailed knowledge of emissions levels, transport, and final environmental disposition …

Synthesis and characterization of 2-chloro-3-benzylthiopyrrolo[1,2-a]- benzimidazol-1-one and 2,3-di(benzylthio)pyrrolo[1,2-a]benzimidazol-1-one.
… benzimidazol-1-one as the major product. Chlorine substitution in 2,3-dichloropyrrolo[1,2-a]benzimidazol-1-one by added benzylthiol occurs in the presence of pyridine to provide the corresponding monosulfide and disulfide derivatives. The first benzylthiol ligand undergoes reaction at the …
