Anthraquinone Sulfonates as Water‐Soluble Photocatalysts: Synthetic Applications and Perspectives
ChemPhotoChem, EarlyView.The development of photochemistry in water is rapidly advancing, and the demand for water‐soluble photocatalysts is increasing. Accordingly, anthraquinone sulfonates are interesting options for the activation of organic molecules through H‐atom transfer, proton‐coupled electron transfer, or the generation of reactive oxygen species.

Method of neutralizing the corrosive surface of amine-cured epoxy resins [PDF]
, 1982 The corrosive alkaline surface layer of an epoxy resin product formed by the curing of the epoxy with an aliphatic amine is eliminated by first applying a non-solvent to remove most or all of the free unreacted amine and then applying a layer of a ...

Limnology and Oceanography, EarlyView.Abstract Purple sulfur bacteria (PSB) of the family Chromatiaceae (Gammaproteobacteria) can perform chemo‐ and photo‐lithoautotrophy (through anoxygenic photosynthesis) in anoxic layers of freshwater stratified (including meromictic) lakes. This group has been extensively studied via physiological and ecological approaches, albeit their genomics has ...

Preparation of highly fluorinated polyurethanes [PDF]
, 1971 New polyurethanes, formed from a reaction of a prepolymer diol and a perfluorinated diisocyanate, are nonflammable and possess high corrosion resistance and good low temperature flexibility.

ChemistryOpen, EarlyView.The direct electrochemical carboxylation of organic halides was carried out in an undivided cell fitted with a sacrificial magnesium anode and a nickel foam cathode. Mechanism investigations account for the in situ generation of an anionic species that is not a genuine Grignard reagent.
