The continuous progress of science and technology requires highly integrated optoelectronic devices, prompting the development of its core component, transparent conductive materials, towards surface patterning but facing difficulties such as poor compatibility and performance balance of high-precision surface patterning processes, resulting in great challenges. To address these issues, we propose a novel method based on laser-assisted transfer technology. Through a synergistic strategy of low-energy laser-induced transfer and high-energy UV laser curing, combined with the design of an ultra-thin transparent conductive UV-curable adhesive layer, the process achieves a balance between surface aptitude and optoelectronic performance through non-contact processing. The technology utilizes UV adhesive to penetrate the conductive network instead of hybrid coating, effectively avoiding nanowire damage and ensuring the continuity of conductivity between the microstructure and the curved substrate, with both high transmittance (>80%@550 nm) and low resistivity ( © 2025, The Authors.

We establish an analytical criterion for stable electrodeposition by combining electrochemistry and mechanics. In situ experiments combined with molecular simulations are performed to validate the robustness of the theoretical predictions. Our analysis shows that stable electrodeposition is intimately linked with the interfacial defect size, fracture toughness, and molar volume of solid electrolytes. We find an exponential scaling law between the critical current density and the interfacial defect size, and the inherent softening in strength of grain boundaries lowers the critical current density in polycrystalline solid electrolytes. Modeling and analyses provide roadmaps to design solid electrolytes with metallic anodes for achieving stable electrodeposition.

The construction of lunar stations for research and living requires high-performance building materials that can adapt the harsh lunar environment. One of feasible building materials is fiber-reinforced composites, for which the composition of glass fibers can be designed like lunar soils, i.e., terrestrial basalt and in turn, the "lunar glass" can be drawn into fibers. Because of a wide variation of TiO2 in lunar soils, our study focused on a series investigation on the effect of TiO2 (0.55 wt% - 6.14 wt%) on fiber spinnability and strength of the simulated "lunar glass and glass fibers". The baseline glass composition was derived from a simulated TiO2-lean lunar soil and other glasses were made at different TiO2 doping levels. The addition of TiO2 was found to reduce the melt thermal stability, there appears a TiO2 threshold (6.14 wt%), at which fibers cannot be drawn without breakage because of melt devitrification. The fiber tensile strength exhibits a nonlinear characteristic with an apparent maximum at 1.52 wt% TiO2. FTIR and Raman spectroscopic studies were carried out to investigate the glass network structure responses to TiO2 modifications and show TiO2 functions as a network modifier, depolymerizing the silicate network. Statistical structure (FTIR & Raman based)–property modeling was attempted to further elucidate the effect of TiO2-induced structure change on Tg and fiber tensile strength. Good agreements were found between the model predictions and the measured values. © 2023, The Authors. All rights reserved.

Protein-protein binding enables orderly and lawful biological self-organization, and is therefore considered a miracle of nature. Protein-protein binding is steered by electrostatic forces, hydrogen bonding, van der Waals force, and hydrophobic interactions. Among these physical forces, only the hydrophobic interactions can be considered as long-range intermolecular attractions between proteins in intracellular and extracellular fluid. Low-entropy regions of hydration shells around proteins drive hydrophobic attraction among them that essentially coordinate protein-protein docking in rotational-conformational space of mutual orientations at the guidance stage of the binding. Here, an innovative method was developed for identifying the low-entropy regions of hydration shells of given proteins, and we discovered that the largest low-entropy regions of hydration shells on proteins typically cover the binding sites. According to an analysis of determined protein complex structures, shape matching between the largest low-entropy hydration shell region of a protein and that of its partner at the binding sites is revealed as a regular pattern. Protein-protein binding is thus found to be mainly guided by hydrophobic collapse between the shape-matched low-entropy hydration shells that is verified by bioinformatics analyses of hundreds of structures of protein complexes. A simple algorithm is developed to precisely predict protein binding sites. © 2022, CC BY.

Wearable/portable devices are essential for the automation, intelligence and digitization of next-generation electronic products. However, it is still challenging to obtain a kind of flexible, transparent and lightweight power source for these. Here, both a dual-electrode poly-(dimethylsiloxane)/copper nanowires (PDMS/Cu NWs) based TENG and a single-electrode mode TENG based on half-embedded Cu NWs electrode and PDMS/Cu NWs negative friction layer was fabricated by cost-effective and feasible methods. Respectively, these as-obtained TENGs show good flexibilities and transparency. Meanwhile, the two kinds of TENG exhibit high output voltages and power densities of 120 V and 2.0 W/m 2 , 45 V and 0.135 W/m 2 , respectively. The enhancements are ascribed to the increase of capacitance and electron flow in the friction layers caused by doping Cu NWs. The advantages of the PDMS/Cu NWs based TENG include the ease of fabrication, good biocompatibility, flexibility and transparency, empowering it as a promising sustainable method for obtaining daily environmental energy as a self-powered source to drive wearable/portable electronic devices. © 2022, The Authors.

Wearable/portable devices are essential for the automation, intelligence and digitization of next-generation electronic products. However, it is still challenging to obtain a kind of flexible, transparent and lightweight power source for these. Here, these were fabricated by cost-effective and feasible methods for both TENG with dual-electrode mode (tribo-negative layer: poly-(dimethylsiloxane)/copper nanowires (PDMS/Cu NWs), trio-positive layer: PET), and TENG with single-electrode mode based on half-embedded Cu NWs electrode and PDMS/Cu NWs negative friction layer s. Respectively, these as-obtained TENGs show good flexibilities and transparency. Meanwhile, the two kinds of TENG exhibit high output voltages and power densities of 120 V and 2.0 W/m2, 45 V and 0.135 W/m2, respectively.
