Crosslink nature in Cr(III)-polyacrylamide gels
(2001)The equilibrium constants of various candidates for the crosslinking reaction between chromium(III) and partly hydrolysed polyacrylamide have been calculated. For this purpose use has been made of a) the crosslinking index ...

The remarkable effect of oxygen on the N2 selectivity of water catalytic denitrification by hydrogen
(2007)The selective catalytic reduction of nitrates (NO3-) in pure water toward N2 formation by the use of gaseous H2 and in the presence of O2 (air) at 1 atm total pressure and 25°C has been investigated over Pd-Cu supported ...

Structure, mechanical and tribological properties of nitrogen-containing chromium coatings prepared by reactive magnetron sputtering
(1999)Cr(1-x)N(x) coatings were deposited by magnetron sputtering at a substrate temperature of 200°C onto AISI 316 stainless-steel substrates immersed in an Ar/N2 plasma. The goal of this investigation was to study the influence ...
