Electromagnetic radiation interferes with the operation of electronic devices and poses a threat to human health, while traditional microwave absorbing materials are difficult to meet the core requirements of being "thin, light, wide and strong". Inspired by the structure of coral reefs, a Chinese research team has designed a ZnNiCo-LDH/MXene composite material. Through biomimetic porous structures and high-density heterojunction engineering, it achieves an electromagnetic reflection loss of -49.6 dB at a thickness of 1.35 mm and a radar cross-section suppression of -39.57 dB · m². This breakthrough provides a brand-new approach to solving the problems of electromagnetic pollution and military stealth technology.

The regulation of electron transfer is crucial for enhancing the catalytic efficiency of catalysts. Currently, CO selective reduction of NO_x (CO-SCR) catalysts with surface synergistic oxygen vacancies (SSOVs) or alloyed components exhibit superior performance but face challenges of reduced activity and stability in oxygen-rich environments. Here, we demonstrate a strategy that combines PtCo alloys (0.01% Pt; 0.04% Co) with SSOVs in cerium zirconium oxide solid solution to interactively modulate the electronic structure, resulting in a significant enhancement of both the activity and stability of the catalyst under oxygen-rich conditions. This catalyst achieved over 85% NO conversion at 300 ℃ and 5% O₂, while maintaining approximately 100% N₂ selectivity during 20 h-stability testing, surpassing the performance of the monometallic catalysts. This enhancement arises from the synergistic electronic effects of alloying and SSOVs, which generate negatively charged Pt that facilitates NO adsorption and dissociation, while concurrently producing electron-deficient SSOVs that weaken O₂ chemisorption and promote the formation of moderate reactive oxygen species. Moreover, the preferential adsorption of CO on Co sites alleviates competitive adsorption.

Precise control of copper's oxidation states in nanorod catalysts enables simultaneous nitrate wastewater purification and glycerol upcycling. Partially reduced copper oxide nanorods convert nitrate to ammonia at 96.8% efficiency, while fully oxidized versions transform glycerol into formate at 93% efficiency. The integrated system slashes energy consumption by 53.5%, offering a sustainable path for chemical production and environmental remediation.

Thermal stability and environmental sustainability are paramount to the practical deployment of perovskite solar cells (PSCs), which are designed to harness solar energy through high-efficiency and low-cost photovoltaic technology. Pseudo-halide thiocyanate anions (SCN⁻), employed as a crystallization modulator, have emerged as an ideal candidate for tailoring the formation of high-quality mixed-cation perovskite films, paving the way for a new era of efficient and high-quality PSCs.

Protein-based drugs demonstrate potent therapeutic effects but face rapid clearance from the body. To address this limitation for FGF21—a crucial neuroprotective protein with a short biological half-life—researchers developed an innovative zinc-based nanoformulation. The team successfully created FGF21/Zinc NC by combining FGF21 with zinc and stabilizing the complex with a PVP coating. This novel formulation demonstrated remarkable efficacy in stroke treatment, representing a significant breakthrough in overcoming a key obstacle for clinical development of protein therapeutics.

Researchers at Graz University of Technology are using virtual reality and large language models to support people with autism spectrum disorder in training social skills. The system is intended to make treatment options more widely accessible.

The Korea Research Institute of Standards and Science (KRISS, President Lee Ho-seong) has developed an ultrasonic sensor technology that applies a waveguide to detect defects in all directions without directly attaching sensors to the inspection target. By enabling remote ultrasonic excitation and reception, the technology is expected to help prevent industrial accidents and eliminate inspection blind spots in high-risk industrial facilities where direct sensor installation has been challenging due to heat, toxic gases, or other hazardous environmental conditions.
