A high performance hydrogen sulfide gas sensor based on porous α-Fe2O3 operates at room-temperature
Abstract Porous α-Fe2O3 nanoparticles were synthesized by simple annealing of β-FeOOH precursor derived from a facile hydrothermal route, the structures and morphologies of the as-prepared productExpand
Surface acoustic wave ammonia sensor based on ZnO/SiO2 composite film.
A surface acoustic wave resonator with ZnO/SiO2 (ZS) composite film used as an ammonia sensor has good selectivity, reversibility and stability at room temperature and can be attributed to the enhanced absorption of ammonia and unique surface reaction on composite films due to the existence of silica.

Effect of Water Vapor, Temperature, and Rapid Annealing on Formamidinium Lead Triiodide Perovskite Crystallization
Perovskite-based solar cells are one of the emerging candidates for radically lower cost photovoltaics. Herein, we report on the synthesis and crystallization of organic–inorganic formamidinium leadExpand
In situ investigation of halide incorporation into perovskite solar cells
Here we report on the material chemistry following crystallization in the presence of water vapor of chlorinated formamidinium lead-triiodide (NH2CH = NH2PbI3−xClx) perovskite films. We found in-situExpand
Reformed Mesoporous Ge for Substrate Reuse in III-V Solar Cells
Mesoporous Ge was generated by bipolar electrochemical etching of (100) Ge. Through high-temperature annealing experiments, we found that the mesoporous Ge microstructure produces pore coalescenceExpand
