Fe-N-C interfacial engineering on commercial Pt/C catalysts, via unique 5d-3d/2p orbital hybridization, enables a breakthrough in fuel cell durability and performance. The engineered PtFe/C@Fe-N-C catalyst maintains 97.3% of its activity after 30,000 accelerated stress cycles. This exceptional stability and its high mass activity decisively surpass both the performance of pristine Pt/C and the U.S. Department of Energy's 2025 technical targets.

Blue perovskite QLEDs are core devices for next-generation full-color displays and energy-saving solid lighting. Although their external quantum efficiency (EQE) has made great progress, the long-standing imbalance between power efficiency and luminescence performance severely restricts practical application. Researchers from Zhengzhou University adopted PVDF ordered dipole engineering to synergistically optimize carrier injection balance and suppress trap non-radiative loss. The fabricated blue perovskite QLEDs achieved record power efficiency (PE) of 43.9 lm W⁻¹ and EQE of 28.7%, together with low turn-on voltage and outstanding luminescent stability. This work breaks the efficiency bottleneck of blue perovskite luminescent devices, and provides a universal scheme for developing low-energy-consumption perovskite optoelectronic products.

A new study explores heterogeneity in unilateral Meniere’s disease, clarifies key clinical and functional differences linked to endolymphatic hydrops, and supports an integrated diagnostic approach for precise patient evaluation.

This study reports a case of deeply embedded cervical fish bone successfully retrieved by ultrasound-guided endoscopy after open exploration failure, proving this technique is a safe, effective and minimally invasive salvage method.

A new study investigates sigmoid sinus wall reconstruction with bone cement for pulsatile tinnitus, clarifying short‑term symptom fluctuations and self‑limiting recovery patterns, providing a reliable basis for postoperative evaluation and clinical counseling.

Global type 1 diabetes (T1DM) burden among children and adolescents aged 0–19 increased during 1990–2021. Incidence rose from 2.71 to 7.42 per 100,000 and prevalence from 20.75 to 56.59 per 100,000. Mortality and YLLs also increased, indicating worsening fatal outcomes. North America and Europe had the highest incidence and prevalence in 2021. Inequalities widened, with poorer countries bearing a growing and disproportionate burden of T1DM mortality and YLLs.
