– We study polymer layers formed by irreversible adsorption from a polymer melt. Our theory describes an experiment which is a “slow” version of that proposed by Guiselin (Europhys. Lett., 17 (1992) 225) who considered instantaneously irreversibly adsorbing chains and predicted a universal density profile of the layer after swelling with solvent to produce the “Guiselin brush”. Here we ask what...

Chemical and morphological heterogeneities of carbon sorbents play important roles in gas-phase adsorption. However, the specific chemical complexes and topological structures of carbon that favor or impede elemental mercury uptake are not well understood and are the subject of this study. Temperature programmed desorption (TPD) with a model carbonaceous material (highly oriented pyrolytic grap...

We successfully synthesized SrNb2O6 with nanoplate morphology by a facile hydrothermal method. The SrNb2O6 nanoplate without any promoters or co-catalysts exhibited promising photocatalytic performance for the preferential reduction of CO2 with H2O vapour to CO and CH4 due to its high electron-hole separation and high CO2 chemisorption abilities.
