CoMn2O4 quantum dots of different sizes, selectively synthesized and supported on carbon nanotubes, showed a strongly size-dependent electrocatalytic performance in the oxygen reduction/evolution processes.

A new strategy was developed to improve Si/metal contacts in organic-Si heterojunction solar cells. It uses black phosphorus induced photo-doping of zinc oxide, and achieves a remarkable power conversion efficiency of 15.2%.

A novel ZnO tribotronic transistor sensor is developed by coupling a ZnO field effect transistor and triboelectric nanogenerator in free-standing mode. By applying an external mechanical force to the device for sliding electrification, the detection sensitivity and resolution of the ZnO tribotronic transistor sensor are improved.

Using molecular dynamics simulations, we demonstrate that chemical functionalization with H, O, and OH can significantly enhance the failure stress and strain of penta-graphene (PG).

We reveal the atomic-scale structure and quasiparticle band gap of chemical vapor deposition-grown monolayer WS2 on Au foil via scanning tunneling microscopy/spectroscopy (STM/STS). Due to the weak interfacial interactions between WS2 and the Au substrate, the band gap of WS2 preserves its relatively intrinsic features on the Au(001) facet, and is not modulated by the striped superstructures that are formed.

The multi-layer coating consisting of hydrophilic and hydrophobic layers successfully protects perovskite solar cells under extremely humid environment. The poly(methyl methacrylate) (PMMA)-polyurethane (PU)-SiO2 layer successfully expels water and the moderately hydrophilic PMMA layer promotes the recovery of the perovskite layer that contains a small amount of water.

1S-MX2 lateral heterostructures demonstrate the successful construction of heterojunctions with excellent stability and properties based on new “building blocks”. Black phosphorus can serve as a potential substrate and the hybrid bidirectional heterostructures possess distinguishable type-II band alignment.

We designed and fabricated heterostructured TiO2/Fe2TiO5 hollow microspheres with single-, double-, closed-double-, triple-, and core–shell structures and different Fe/Ti molar ratios using a facile sequential templating approach. When tested as oxygen evolution reaction materials for water splitting, the closed-double-shelled TiO2/Fe2TiO5 hollow microspheres with 35% Fe exhibited the highest oxygen evolution reaction rate up to 375 μmol·g−1·h−1 and good stability for 5 h, which is competitive among most Ti–Fe-based photocatalysts.

Metal atom diffusion between Pt nanoparticles and a SnNi support (under appropriate conditions) formed SnNiPt ternary alloys on the surface of an assembled three-dimensional (3D) radial nanostructure composed of SnNi nanoneedles. Combining the all-orientation accessibility of the 3D nanostructure and the advantages of the alloy catalyst, a desirable methanol oxidation electrocatalyst was well-designed with higher activity, better CO poisoning resistance, lower onset potential, and favorable stability.
