Comprehensive and accurate measurements of the saturated-liquid and saturated-vapour densities together with the vapour pressure of pure nitrogen were carried out from the temperatureT=64 K (triple-point temperatureTt=63.151 K) to 0.0222 K below the critical temperature. The typical values of the ...
Replacing scarce and expensive platinum (Pt) with metal–nitrogen–carbon (M–N–C) catalysts for the oxygen reduction reaction in proton exchange membrane fuel cells has largely been impeded by the low oxygen reduction reaction activity of M–N–C due to low active site density and site utili...
Finally, I demonstrate that the dopant concentration of nitrogen-doped graphene is increased at lower synthesis temperatures and higher NHconcentration, up to 1.3 %, but with an associated decrease in the growth rate. Direct visualisation, elemental confirmation, and electronic characterisation of ...
Reduction of microbial density level in wastewater activated sludge via freezing and thawing This note has employed a freeze/thaw method for treating activated sludge, with especial attention for the reduction capability of microbial density. The s... CP Chu,WC Feng,BV Chang,... - 《Water Resea...

Effect of anaerobiosis on aspects of avocado fruit ripening Avocado fruits (, cv. Fuerte) were treated with ethanol vapour (0.5%) or nitrogen (97%) for 40 hrs and stored at 17掳C for 7 days. Fruit softening was reta... S Dori,JN Burdon,E Lomaniec,... - 《Acta Horticulturae》 被引...
Measurements of atomic nitrogen flux were conducted by mass-spectrometric analysis of the products of the reaction with nitrogen monoxide. Vibrational temperature of N2 molecules was measured by plasma emissive spectroscopy. Electron temperature and density was measured by Langmuir probe....
