Summary: Passivation of oxide-based thin film transistors still poses a challenge due to the need for thermal treatments, which can impact the transistor characteristics. By reducing the growth temperatures of passivation layers, the performance of TFTs can be maintained within an acceptable range. Among all devices, TFTs with Al2O3 PVLs deposited at 100 degrees C using H2O as oxidant exhibit high mobility, proper threshold voltage, low subthreshold swing, and excellent stability.

Summary: Thin nanocomposite films of Co3O4-ZnO were synthesized by solid-phase pyrolysis. The films show a wurtzite phase of ZnO and a spinel structure of Co3O4. Increasing annealing temperature and Co3O4 concentration result in larger crystallite sizes. The optical properties and charge carrier mobility of the films are influenced by the Co3O4 content. Photosensors based on the films exhibit enhanced photoresponse in specific wavelength ranges.

Summary: Fabric-based nano semiconductor photocatalysts have attracted much attention recently. In this study, Ag2O/ZnO nanorod (NR)/Al-ZnO p-type/high resistivity/n-type (P-HR-N) heterojunction arrays were used to modify polyester fibers. The Al-ZnO seed layer was sputtered on the fibers and Al doping was employed to change the work function (WF) of the ZnO film. The resulting P-HR-N heterojunction sample showed enhanced photocatalytic performance due to the high and widened built-in electric field (BEF) in the multilayer film.

Summary: Thin film coatings with potent antibacterial properties are widely used in medical devices, frequently touched surfaces, and food packaging. However, achieving antibacterial performance under both light and dark conditions remains a challenge. In this study, we successfully prepared AgBr-coated ZnO nanorod thin film architecture using a unique surfactant-mediated solution-phase spin-coating approach. The resulting structures showed dual functionality as antimicrobial agents and photosensitizers, effectively enhancing the visible-light photodisinfection efficacy of ZnO nanorods. The concentration of the surfactant-based precursor solution could be modulated to control the AgBr content. Additionally, components like urea and lactic acid were found to enhance the photocatalytic efficiency of the structures.

Summary: The construction of a p-n heterojunction photocatalyst successfully overcomes the low photo-catalytic activity caused by rapid charge recombination and limited photo-response range. In this study, an interlayer of expanded MoS2 coupled with Bi2WO6 (BW-IEM) photocatalyst was synthesized, achieving a Methylene Blue (MB) removal rate of up to 97% (5.18 x10-2 min-1) under the irradiation of low power 1W LED white light. The outstanding photocatalytic performance of the p-n heterojunctions BW-IEM photocatalyst is attributed to the enhancement of light harvesting, improvement in the separation of charge carriers, and coexistence of oxygen vacancy. The main reactive oxygen species (ROS) responsible for the photo-degradation of MB were center dot Oz radicals and center dot OH. This work provides a new strategy for the potential IEM photocatalyst as a matrix in a p-n heterojunction composite.

Summary: This study investigates the effects of silica on polyacrylamide (PAM) using comprehensive rheological data. Modified PAM shows distinct chemical structures compared to bare PAM, but both are hydrophilic fluids. The rheological performance of all modified PAM shows an undulated trend for all concentrations of silica and selected temperatures, but all modified PAM perform better than bare PAM. Therefore, a formulation of 0.5 wt% silica is promising for PAM modification, even simulating the performance of bored pile drilling. In terms of thermal stability, the rheological performance of bare PAM and modified PAM shows better results at 60 and 40°C, respectively.

Summary: In this study, indium (In) ions were introduced into flexible Cu2ZnSn(S,Se)(4) (CZTSSe) solar cells to modify the back interface and passivate deep level defects in CZTSSe bulk. The results showed that In doping effectively inhibited the formation of secondary phase and V-Sn defects, decreased the barrier height at the back interface, passivated deep level defects in CZTSSe bulk, increased carrier concentration, and significantly reduced the V-OC deficit. Eventually, a flexible CZTSSe solar cell with a power conversion efficiency of 10.01% was achieved. This synergistic strategy of interface modification and bulk defects passivation through In incorporation provides a new approach for fabricating efficient flexible kesterite-based solar cells.
