Summary: We present a method for fabricating porous polymer thin films based on chemical vapor deposition, which allows control over pore size, pore morphology, and film thickness. By co-depositing crystallizable porogen molecules with cross-linked poly(glycidyl methacrylate) thin films, we can create porous films with different pore sizes and porosities.

Summary: This study investigated the properties of Cu3Sb(Sx,Se1-x)4 thin films and found that the selenium source temperature significantly influenced the film's performance, with an increase in selenium concentration leading to a decrease in band gap. The results also showed that the thin films exhibited p-type electrical behavior and distinct photoconductivity.

Summary: In this study, a uniform superhydrophilic coating was prepared by grafting AEAOS onto nanosilica and coated on aluminum alloys to reduce water droplet generation. The surface state, composition, and roughness of the coatings were characterized using SEM, EDS, and optical profilometer. The hydrophilicity and adhesion of the coating films were evaluated. The results showed that the amino groups promote the silane grafting on the surface of nanosilica, and the 10% addition of AEAOS gives the modified silica film superhydrophilic properties.

Summary: Clusteroluminescence (CL) has gained significant attention, but the development of red emission clusteroluminogens (CLgens) with adjustable CL is still in its early stages. In this study, a simple heating process was used to prepare red emission poly(maleic anhydride-alt-vinyl acetate) (PMV) derivatives with a tunable maximum emission wavelength between 620 and 675 nm. The heating process promoted the formation of clusters and enhanced through-space conjugation, resulting in adjustable emission wavelength and higher quantum yield. Additionally, cost-effective and eco-friendly core-shell PMV particles were prepared as agricultural light conversion agents and demonstrated compatibility with polyethylene.

Summary: Highly flexible silver nanowire-based transparent conductive films (AgNWs TCFs) were successfully fabricated and further processed into transparent film heaters. By optimizing the coating parameters, low resistance, high transmittance, and good mechanical stability were achieved. The slot-die coating method shows great potential for large-scale production of AgNW-based film heaters, which can be widely used in window defrost and deicer systems.

Summary: Nanofiber membranes made of polycaprolactone and bioactive glass nanoparticles were prepared using electrospinning. The incorporation of bioactive glass increased the crystallinity of polycaprolactone, and nanofibers containing 5% bioactive glass showed the best mechanical properties. Atorvastatin-loaded nanofibers with a 10% coating polymer exhibited gradual drug release and promoted wound closure in human skin fibroblast cells.

Summary: This study prepared amorphous As33S67 thin films by both solution processing and thermal evaporation, and doped them with silver ions. The results showed that the doped films had good optical properties, such as decreased optical bandgap and increased refractive index. The doping mechanisms of the films prepared by solution processing and thermal evaporation were significantly different.

Summary: The microstructure, electrochemical responses, and passive film characteristics of FeCrMoWCBY bulk metallic glasses (BMGs) under Ar+ irradiation were studied. The BMGs maintained an amorphous structure and showed excellent corrosion resistance in 1 mol/l HCl solution at high irradiation fluence. With increasing irradiation fluence, crystal-like clusters and nanocrystals precipitated from the exterior amorphous matrix, leading to the destruction of passive films and a weakened anti-corrosion capacity. This finding facilitates the potential application of Fe-based BMGs under extreme nuclear-irradiated conditions.
