Incorporating Si into Sb2Se3: Tailoring Optical Phase Change Materials via Nanocomposites

open access: yesAdvanced Optical Materials, EarlyView.
We study the structural, optical, and thermal effects of adding silicon to Sb2Se3 and demonstrate that the as‐deposited solid solution phase segregates after electro‐thermal switching, creating a nanocomposite with effective‐medium properties and a phase‐change response.

Enhancement of the Ultraviolet Stability of Perovskite Solar by the Interface Modified with Cesium Chloride

open access: yesAdvanced Photonics Research, EarlyView.
CsCl interface modification promotes perovskite growth and suppresses recombination, boosting n–i–p perovskite solar cells (PSC) efficiency from 21.21% to 23.73% and enhancing UV stability fourfold, offering a simple route to efficient, stable PSCs. Stability is an important factor affecting the application of perovskite solar cells (PSCs).

BioCNTs Mediated Delivery of Systemically Mobile Small RNAs via Leaf Spray to Control Both Tomato DNA and RNA Viruses

open access: yesAdvanced Science, EarlyView.
A carbon nanotube‐based biopesticide system (BioCNTs) enables efficient delivery and systemic movement of RNAi molecules to control major tomato viruses. By integrating shRNA and tRNA‐like structures (TLS) with BioCNTs, this green and scalable approach achieves long‐term silencing and high antiviral efficacy through simple foliar spraying.

Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

open access: yesAdvanced Science, EarlyView.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental
