Summary: MoS2 nanoflowers modified with SnO2 quantum dots were prepared by hydrothermal method and used for ethanol detection. The composites were analyzed for morphology, structure, and composition. The results showed that SnO2 QD modified MoS2 had higher response, better selectivity, and lower operating temperature than SnO2 QD. The enhancement in ethanol sensing performance was attributed to large surface area and dangling bonds of MoS2 nanoflowers, as well as the formation of heterojunction between SnO2 and MoS2.

Summary: CsPbCl3 perovskite films were successfully grown on quartz substrates by RF-magnetron sputtering method, and their photoluminescence properties were studied over a temperature range of 10 K to 300 K. A near bandgap emission peak (around 410 nm) was observed in the violet region with a few nanoseconds lifetime at room temperature. Surprisingly, this peak exhibited a non-monotonic shift with increasing temperature, unlike traditional semiconductors or the same group of perovskites. The origin and temperature-dependent shift of this peak can be well explained by the Bose-Einstein two-oscillator model, which takes into account the interaction between electrons and phonons.

Summary: The effect of substrate on the domain structure and bulk photovoltaic property in BiFeO3 films is reported. It is observed that BiFeO3 films can be epitaxially grown on TbScO3 substrate with a 45 degrees rotation domain. Compared with LaAlO3 substrate, the TbScO3 substrate promotes the formation of periodic 71 degrees ferroelectric domain wall in BiFeO3 films, as demonstrated by piezoelectric force microscopy measurements. Illumination of the BiFeO3 film on TbScO3 substrate by 1 sun AM 1.5 G results in a higher open-circuit voltage of 9.66 V, exceeding the band gap of BiFeO3. These findings contribute to a better understanding of the relationship between domain structure and bulk photovoltaic properties in BiFeO3 films.

Summary: To improve the stability and electrochemical activity of lithium-ion battery (LIB) anodes, a new strategy was developed by doping phosphorus into a hybrid of NiCo-layered double hydroxide (NiCo-LDH) nanosheets and three-dimensional (3D) multilayered V2C MXene. The 3D conductive network and large surface area of V2C MXene enabled rapid charge transfer and electrolyte storage, while the unique structure of MXene resisted volume expansion and prevented accumulation and breakage of NiCo-LDH. This strategy resulted in high-performance LIBs with outstanding electrochemistry performance and the potential for application in other energy storage devices.
