A two-dimensional lateral transition metal disulfide-oxide-disulfide heterostructure with a configuration of an ultrathin Nb₂O₅ channel and two metallic NbS₂ electrodes is fabricated by a simple lithographyfree, laser-patterning technique. The heterostructure can be used as an ultrasensitive two-terminal sensor based on the modulation of Nb₂O₅ surface conduction through the naturally adsorbed water molecules.

A promising device for high performance and excellent stability in inorganic CsPbI₃ perovskite solar cell is demonstrated. The addition of In³⁺ into CsPbI₃ films can enter the perovskite crystal lattice and partially replace Pb²⁺, which could retard the crystallization to form the large grain, free-pinholes, and compact films, resulting in the good charge transport and stability.

A graphene/TiO₂ nanocrystals hybrid has been prepared by directly growing TiO₂ nanocrystals on graphene oxide (GO) sheets by a two-step method, in which TiO₂ was first coated on GO sheets by hydrolysis and subsequently crystallized into anatase nanocrystals by hydrothermal treatment. The graphene/TiO₂ nanocrystals hybrid shows superior photocatalytic activity to other TiO₂ materials in the degradation of rhodamine B, with an impressive three-fold photocatalytic enhancement over P25
