Molecular Anchoring Strategies for Enhanced Thermal Stability in Organic Field-Effect Transistors.

Thermally stable organic transistors are crucial for ensuring reliable performance in diverse applications, including high-temperature environments and thermally demanding electronic systems. However, developing thermally stable organic semiconductors with excellent charge transport capability remains a great challenge. Here, a thermally stable and high-performance organic semiconductor, [1]benzothieno[3,2-][1]benzothiophene (BTBT) derivative BTBT-PO8OP, is designed by incorporating a phenyl-anchored unit in the side chain.

UV/Ozone-Induced Interface Engineering for High-Performance Horizontal Organic Light-Emitting Transistors Operating at Low Voltage.

Multifunctional organic light-emitting transistors (OLETs), which combine electric-switching and light-producing capabilities into a single device, are attracting increasing interest as promising candidates for new-generation display technology. Despite advancements in the design of organic luminescent materials and the optimization of device geometry configurations, maintaining operating voltage low while enhancing optical performances remains a key challenge in horizontally structured OLETs. Here, a simple and effective interfacial engineering strategy is employed to improve the optical properties of horizontal OLETs operating at low voltage, by introducing ultraviolet ozone (UVO)-induced surface modification on high-k dielectrics.

Facile cross-link method to synthesize chitosan-based adsorbent with superior selectivity toward gold ions: Batch and column studies.

The recovery of gold from wastewater has received significant attention in the last years due to its high economic value and low availability. A novel chitosan-based adsorbent (CS-GTU) was successfully synthesized by using formaldehyde as a crosslinker between chitosan and guanylthiourea, and applied for selective adsorption of Au from an aqueous medium. Through batch experiments, the maximum adsorption capacity of CS-GTU for Au could reach up to 695.

High-temperature dielectric properties and pyrolysis reduction characteristics of different biomass-pyrolusite mixtures in microwave field.

Exploring the dielectric properties of mineral-biomass mixtures is fundamental to the coupled application with biomass pyrolysis and microwave technology to mineral reduction. In this work, the microwave dielectric properties of five pyrolusite-biomass mixtures were measured by resonant cavity perturbation technique and the pyrolysis reduction characteristics were systematically investigated, including poplar, pine, ageratina adenophora, rapeseed shell and walnut shell. Results indicated that the dielectric properties commonalities of five mixtures with temperature represented by increasing firstly, dropping intensely and finally rising slightly, with excellent responsiveness to microwaves; which the change trend was mainly attributed to the crystal transformation of amorphous MnO and pyrolusite reduction reactions by biomass pyrolysis.
