Solar thermoelectric generators(STEGs) that can effectively harvest solar energy and convert it into affordable electricity, provide a promising solution for self-powered wearable electronics and the Internet of Things(Io T). However, their electricity generation is often limited by the low thermal concentration or unstable temperature gradients in practical applications. Herein, we rationally designed an organic radical-activable charge-transfer(CT) cocrystal based on the open-shell radical electron acceptor of2,6-dibromonaphthalene-1,4,5,8-tetracarboxylic dianhydride. The open-shell radical contributes to the strong near-infrared absorption and nonradiative recombination, resulting in a high photothermal conversion efficiency of 67.2% for the prepared CT cocrystal. Furthermore, the photothermal ink containing the radical-activable CT cocrystal and the transparent resin was successfully coated onto a thermoelectric generator as a cost-effective light absorber, facilely forming a high-performance ***, the prepared STEG output a voltage of 143 m V under 1 sun irradiation, demonstrating real-time photodetection capability. We anticipate the potential applications of these cocrystals in self-powered optoelectronics, such as a non-contact and long-distance information converters.

The SiC nanocomposite Mg2(Si0.4Sn0.6)Sb0.015/SiCy (0≤y≤0.01) were prepared using the vacuum induction melting (IM) technique in conjunction with mechanical alloying and spark plasma sintering (SPS) process (referred to as the IM+SPS process). The microstructure and thermoelectric properties were systematically investigated. The hierarchical nanostructures are composed of point defects, SiC nanocomposite particles, coherent in-situ nanophases, and grains. The SiC nanocomposite cause a minor reduction in electrical performance, and the constructed hierarchical nanostructures significantly decreased the lattice thermal conductivities. The highest ZT value of 1.55 is obtained at 643 K for the Mg2(Si0.4Sn0.6)Sb0.015/SiC0.0075 nanocomposite sample. © 2023, The Authors. All rights reserved.

Lead-free perovskites have become a focal point in the quest for non-toxic and stable materials for optoelectronic applications. Despite this interest, achieving blue light emission from lead-free halide double perovskites Cs2AgInCl6 at room temperature remains a significant challenge, hindering their commercial viability. In this study, we address this issue by synthesizing the rare earth lead-free double perovskite Cs2Ag0.6Na0.4In0.8Bi0.2Cl6:Yb, which demonstrates visible/NIR light emission at 598 and 1000 nm upon blue light excitation at room temperature. We show that this excitation stems from complex interactions between energy level splitting induced by Yb and self-trapped exciton energy levels. Notably, we observe that under blue excitation, the photoluminescence intensity increases with temperature. Furthermore, Cs2Ag0.6Na0.4In0.8Bi0.2Cl6:Yb was integrated into a blue light-emitting diode, enhancing the conversion efficiency of GaAs solar cells as a down-shifting layer. Ultimately, this research opens new avenues for developing eco-friendly, efficient materials with significant implications for sustainable technology. © 2025, The Authors. All rights reserved.

Synergistically Enhanced the Strength and Ductility of Network-Structured Titanium Matrix composites Reinforced with B-Containing Precursor-Derived TiB Nanowires

Improving the aspect ratio of TiB whiskers is of great importance for addressing the strength-ductility trade-off of TiB-reinforced Ti matrix composites (TCMs), which is accomplished primarily through introducing boron-containing nanoceramics via powder metallurgy. However, this technique can cause whisker clusters at grain boundaries and increase the oxygen content resulting in a marked decrease in ductility. Herein, a network-structured architecture constructed by high-aspect-ratio TiB nanowires has been proposed and realized through boron-containing precursor shell-layer encapsulation on Ti particles and consolidation by spark plasma sintering. The in-situ derived TiB nanowires with aspect ratios up to 304.4 through unique SLS growth mechanism contribute to the high strength (1318 MPa) and sufficient ductility (5.34%) of TCMs. Simultaneously, the dual-strategy of active deoxidation effect originated from the reductive pyrolysis gas and passive prevention of impurity O based on the precursor shell-layer without lengthy ball-milling can significant removal of the oxygen from TCMs. © 2023, The Authors.
