Biomimetic coral reef structures drive breakthroughs in microwave absorption materials—trimetal LDH and MXene self-assembled composite materials achieve efficient electromagnetic wave attenuation
Tsinghua University PressElectromagnetic 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 dual electronic effects of alloying and synergistic surface oxygen vacancy in PtCo/CeZrOx enhance NOx reduction by CO
Tsinghua University PressThe regulation of electron transfer is crucial for enhancing the catalytic efficiency of catalysts. Currently, CO selective reduction of NOx (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.

Valence control unlocks bifunctional copper catalyst for sustainable chemical production
Tsinghua University PressPrecise 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.

Pseudohalide engineering for crystallization kinetics and defect passivation in two-step fabricated Cs0.1FA0.9Pb0.9Sn0.1I3 perovskite solar cells with exceptional efficiency and stability
Tsinghua University PressThermal 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.

Facile-prepared FGF21/zinc nanocomplex for efficient brain delivery in ischemic stroke treatment
Tsinghua University PressProtein-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.
