Summary: 2D materials have unique properties and easy processability, making them attractive for printed electronics. Hexagonal boron nitride (h-BN) is commonly used as a dielectric in printed devices, but its limitations in low-voltage applications have led to the exploration of anatase TiO2 nanosheets (TiO2-NS) as a printable dielectric ink. In this work, water-based and printable solvent formulations of TiO2-NS are demonstrated to have sub-micron thickness and can be used in printed diodes and transistors, showcasing their potential for printed electronics.

Summary: 1T-MoS2 is grown in situ on TiO2 nanotubes using a hydrothermal method to form a 1T-MoS2@TNTs composite, showing enhanced photocatalytic performance for tetracycline hydrochloride degradation under visible light. The optimized photocatalytic activity is closely related to the loading amount of 1T-MoS2, where 0.5 wt % 1T-MoS2@TNTs can degrade 57% in 1 hour, the highest efficiency observed experimentally so far. The introduction of 1T-MoS2 is speculated to improve light absorption and charge separation/transport, with identified active species and proposed reaction mechanism.

Summary: Wide bandgap oxide semiconductors have attracted significant attention, but the lack of high mobility p-type oxide semiconductors has limited their applications. This study focuses on beta-TeO2 as a promising p-type oxide semiconductor. Through experimental and computational methods, the electronic structure of beta-TeO2 is investigated, revealing that its valence band is composed of hybridized Te 5s, Te 5p, and O 2p states, while its conduction band is dominated by unoccupied Te 5p states. The hybridization between Te 5s(2) and O 2p states helps to reduce localization in the valence band, leading to high hole mobility. The structural distortions of beta-TeO2 lattice contribute to the stability of the hybridized states. Overall, beta-TeO2 is a highly competitive material for next-generation opto-electronic devices due to its large bandgap, high hole mobility, two-dimensional structure, and excellent stability.

Summary: In this study, ultrafine Pr-ZrSiO4 yellow pigments with a remarkably narrow size distribution were obtained by modulating the fluorine-assisted crystallization of zircon in a facile way. Through the comprehensive analysis of reflection, absorption, excitation, and emission spectra, the coloration mechanism of Pr-ZrSiO4 yellow pigments was systematically revealed. Both Pr4+ and Pr3+ coexisted in the pigments, with Pr4+ contributing primarily to the ligand-to-metal charge transfer and generating the yellow hue, while Pr3+ tended to discolor the pigments. Therefore, an oxidizing atmosphere is preferable for the production of brilliant Pr-ZrSiO4 pigments with enhanced chromatic properties.

Summary: In this study, we present a strategy of using single-layer perovskite quantum dots film to solve the electroluminescence spectra shift in pure-blue perovskite LEDs, and improve the LED efficiency by co-doping copper and potassium. Our results show that we achieved stable electroluminescence spectra centered at 469 nm in pure-blue halide perovskite QD-LEDs, even at a current density of 1,617 mA.cm(-2). The optimal device exhibited a maximum external quantum efficiency (EQE) of 2.0%. The average maximum EQE and luminance of the LEDs increased by 62% and 66%, respectively, compared with the control LEDs. This study provides an effective strategy for achieving spectra-stable and highly efficient pure-blue perovskite LEDs.

Summary: Constructing a heterojunction of hierarchical and porous NiO/TiO2 layers is effective for improving gas sensing properties. The hydrogen sensor designed in this study consists of NiO nanowalls with exposed (111) facets on top and (002) oriented TiO2 nanorod arrays at the bottom. The heterojunction-induced high energy crystal surfaces and surface depletion region enable the sensor to have a wide detection range and a higher response to hydrogen. The optimized size of the pores between the walls provides excellent interference prevention from CO.

Summary: In this study, high temperature weak ferromagnetism was achieved by intercalating rubidium into the shortest poly(para-phenylene) molecule-biphenyl. The synthesized material exhibited a typical antiferromagnetic transition at 48.5 K, accompanied by a ferromagnetic character in the magnetically ordered region. The weak ferromagnetism was produced by intralayer spin-canted antiferromagnetic and interlayer ferromagnetic spin couplings. This finding enriches the physicochemical functionality of biphenyl and provides a new avenue for the search of it-electron organic magnets in poly(para-phenylene) molecules.

Summary: Exploring high efficiency S-scheme heterojunction photocatalysts with strong redox ability for removing volatile organic compounds from the air is of great interest and importance. However, how to predict and regulate the transport of photogenerated carriers in heterojunctions is a great challenge. In this study, density functional theory calculations were used to predict and synthesize a CdS quantum dots/InVO4 atomic-layer (110)/(110) facet S-scheme heterojunction with enhanced photocatalytic degradation rate for ethylene. Various experiments were conducted to validate the enhanced dissociation of photoexcited excitons and separation of free charge carriers, as well as the formation of S-scheme charge transfer pathways. The study also investigated the reaction mechanism of the photocatalytic C2H4 oxidation using in-situ electron paramagnetic resonance. This work provides insights into construction and optimization of semiconductor heterojunction photocatalysts for environmental remediation.

Summary: A self-assembled mulberry-like ZnO/SnO2 hierarchical structure is constructed using a two-step hydrothermal method for the development of metal oxide semiconductors-based methane sensors. The resulting sensor exhibits excellent response of approximately 56.1% to 2000 ppm CH4 at room temperature and low power consumption. It is found that the strain induced at the ZnO/SnO2 interface greatly enhances the piezoelectric polarization on the ZnO surface, leading to significant improvement in the sensing performance of the methane gas sensor at room temperature.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
