Summary: In this study, a novel TiO2@g-C3N4@biochar composite photocatalyst was successfully fabricated and characterized. The composite photocatalyst exhibited high photocatalytic oxidation activity for ciprofloxacin (CIP) under UV-vis and visible light irradiation. The photocatalytic removal performance of CIP was influenced by the initial concentration, catalyst dosage, and pH value, and the composite photocatalyst showed excellent stability and reusability. The proposed mechanism of the CIP photocatalytic oxidation reaction provides an effective strategy for removing antibiotics in wastewater.

Summary: In this study, g-C3N4/diatomite composites were synthesized by mixing melamine and diatomite in hydrochloric acid aqueous solution and calcining the mixture at 550 degrees C for 2 hours. The CN/DE-10 composite exhibited the best photocatalytic performance, degrading over 95% of RhB solution in 50 minutes, with a reaction rate constant 6.4 times that of pure g-C3N4. The enhanced specific surface area, improved light absorption ability, and reduced recombination rate of electrons and holes contributed to the outstanding photocatalytic performance of CN/DE-10.

Summary: ZnO/g-C3N4 composite photocatalyst is prepared by ultrasonic dispersion method for Rhodamine B (RhB) degradation from wastewater. The ZnO/g-C3N4 showed enhanced photocatalytic activity due to the heterojunction between ZnO and g-C3N4, which promoted the effective separation of photogenerated carriers. The photocatalytic degradation mechanism of RhB conformed to the S-scheme mechanism combined with DFT calculation.

Summary: The MIL-53Fe@g-C3N4 samples were prepared by solvothermal method and recorded as CM-x. The potocatalytic activity of the MIL-53Fe@g-C3N4 was significantly higher than MIL-53Fe, possibly due to the successful construction of a heterojunction promoting the migration and separation efficiency of photo-generated electron and hole pairs.

Summary: We report Si flexoelectronic transistors (SFTs) that can convert mechanical actuations into electrical control signals and achieve electromechanical function. The metal-semiconductor interfacial Schottky barriers' heights and the channel width of SFT can be modulated using the strain gradient-induced flexoelectric polarization field in Si, resulting in tunable electronic transports with specific characteristics. These findings provide insight into the mechanism of interface gating and channel width gating in flexoelectronics and develop highly sensitive silicon-based strain sensors, which have great potential for constructing next-generation silicon electromechanical nanodevices and nanosystems.
