Summary: In this study, a durable transparent superhydrophobic (DTS) coating was fabricated using methylacryloxypropyltrimethoxysilane (MEMO) polymerized to PMEMO as an adhesive. Hydrophobic SiO2 nanoparticles were fixed in the swollen PMEMO network to prevent micro-roughness caused by aggregation. The coating layer exhibited high light transmission and maintained its superhydrophobicity even under impact and heat treatment. This preparation method is universal and scalable, with promising application prospects.

Summary: A novel approach inspired by traditional Chinese noodle-making process was demonstrated for the preparation of superhydrophobic membrane using electrospinning. The method involves collecting fibers on a metal substrate covered with superhydrophobic nanopowders, resulting in membranes with superhydrophobic properties, especially when the substrate is heated. This noodle-making-like electrospinning process is believed to offer a simple and new way for fabricating superhydrophobic membranes and expanding the application of electrospinning technique.

We developed a serum-free freezing solution that showed promising results in preserving differentiated neuronal cells. Evaluation of the freezing solutions was based on cell viability, recovery rate, and morphology. Cryoprotectants like fetal bovine serum, antifreeze proteins, and sugars were found to be essential for protecting against freeze damage.

Summary: This work demonstrates that photodeposition of Rh species on ZnO-ZnS heterostructure (ZnO/ZnS) can enhance their photocatalytic activity and secure their stability. As little as 0.02 at.% of Rh photodeposition can dramatically increase the activity and reduce self-corrosion of ZnO/ZnS. The optimal catalyst achieved an average H-2 production rate of 5.31 mmol(-1) g(-1) h(-1) and a maximum quantum efficiency of 22.9% at 365 nm.

Summary: Semiconductor-based photocatalyst materials have played a crucial role in the degradation of organic compounds. Photocatalysis is a simple, cost-effective, and environmentally friendly method for degrading organic compounds. In this study, vanadium pentoxide (V2O5) and V2O5/RGO (reduced graphene oxide) composite materials were synthesized using a hydrothermal method. The prepared samples were characterized using various techniques. Raman analysis confirmed the presence of RGO characteristic peaks in the composite and different vibrational modes of V2O5. The V2O5/RGO composite exhibited superior photocatalytic performance compared to V2O5, indicating the importance of both the catalyst and light in the degradation process.
