An interfacial assembly strategy has been developed for the construction of TiO2 heterostructure modified with carbon nitride nanosheets (CN-NSs). The uniform dispersion of TiO2 nanoparticles effectively restrains the re-stacking of ultrathin layers, resulting in a high specific surface area of 234.0 m2﹞g−1, and enhanced photocatalytic efficiency for the degradation of dyes and H2 production.

Water monomers,dimers,and trimers show different adsorption properties on silicene.On silicene,hydrogen bonding in dimers and trimers of water induces a transition from physisorption to chemisorption and then to dissociation.Unlike other 2D materials, silicene is hydrophilic owing to this hydrogen bond autocatalytic effect.

Penta-twinned bipyramidal Au microcrystallites with a highly corrugated morphology host unconventional non-FCC Au phases. The mole-fraction of non-face-centered cubic (non-FCC) Au is varied simply by changing the shape-directing Ag (I) content and the thermolysis temperature. The highest mole fraction of non-FCC Au achieved was 85%. The strained non-FCC phases obtained exhibited nearly three orders of magnitude higher catalytic activity compared to that from the FCC phase or from an uncatalyzed reaction. This catalytic improvement is due to the higher d-band energy associated with the non-FCC phases.

This reaction is not affected by the presence of abasic sites and 5-formyl-2'-deoxycytosine, the modified cytosine counterpart of 5fU. We further developed an oxidation-labeling strategy to detect 5-hydroxymethyl-2∩-deoxyuridine (5hmU) via the chemical oxidation of 5hmU to 5fU.

Porous Co-N/C hollow spheres were successfully prepared by carbonization of metanilic anions in the confined space between the layers of cobalt-aluminum layered double hydroxides.These Co-N/C catalysts exhibited remarkably high electrocatalytic activity and durability for the oxygen reduction reaction at different pH levels.The Co-Nx sites act as the oxygen reduction reaction (ORR) active sites in acidic and neutral solutions,but have a negligible effect on ORR activity in alkaline conditions.

A theoretical analysis of the stimulated emission of monolayer MoS2, taking into consideration the piezoelectric effect, has been conducted using quantum mechanics. It is observed that the extra piezoelectric charges induced by the applied mechanical forces increase the overall charge density of MoS2, subsequently enhancing the emission intensity.
