Acid-base and complexation properties of gem-disubstituted phosphorus acids,viz.,methylenediphosphonic,1 -hydroxyethylidene-1,1-diphosphonic,P,P'-diphenylmethylene-diphosphinic,and P,P'-diphenyl-l-hydroxyethylidene-1,1-diphosphinic acids,were studied in aqueous solutions and in the presence of ...
proton hop.The modifications of the solvation structure and transport properties of the excess proton in concentrated acid solutions were further investigated. ... Chris Knight and Gregory A. Voth - 《Accounts of Chemical Research》 被引量: 132发表: 2012年 The Curious Case of the Hydrated Proton...
Gathered here are those chemical properties which are not covered under the general headings of phase equilibria and crystal structure. The chemical properties of a feldspar can be considered from many viewpoints: thus a crystal chemist emphasizes the ch
It is concluded that the reason for the lower acidity of phenol formaldehyde sorbents relative to phenol in an aqueous solution is the smaller amount of firmly bound water.关键词: Experimental/ organic compounds pH solutions/ acid-base properties phenol groups phenol formaldehyde sorbent acidity ...

Once inside the pathogenic cell, 0D materials can disrupt internal cellular processes (metabolic process, deoxyribonucleic acid (DNA) transcription, respiration, etc.) and also damage internal cellular material (DNA, ribosomes, and plasmids, etc.)76. The precise mechanism is dependent on the ...
Increased CO2concentrations and associated temperature may affect physicochemical soil properties and in particular weathering processes. Indeed, rising atmospheric CO2concentration was found to increasesoil acidity, although carbonic acid is only a weak proton source. This effect may be even stronger under...
