Scalable Perovskite Quantum Dot Glass Nanocomposites for High‐Efficiency Luminescent Solar Concentrators

Advanced Functional Materials, EarlyView.
This study evaluates the scalability of PQD GNC‐based LSCs for BIPV applications. Experimental data and Monte Carlo simulations predict performance up to 1 m2, achieving a peak power conversion efficiency of 3.17%. The results confirm the viability of these LSCs for energy‐efficient building applications.

Cu2O/Cu Chiral Catalysts for Highly Selective Solar‐Assisted CO2‐to‐CO Electroreduction

Advanced Functional Materials, EarlyView.
To address the poor target‐product selectivity of the eCO2RR, breakthrough approaches based on the chiral‐induced spin selectivity phenomenon enhance the Faradaic efficiency (FE) for target hydrocarbons, such as CO. To induce this spin polarization strategy in Cu2O/Cu catalysts, it is proposed using amine‐based intermediate organic molecules with ...

Synthetic Bilirubin‐Based Nanomedicine Protects Against Renal Ischemia/Reperfusion Injury Through Antioxidant and Immune‐Modulating Activity

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
BX‐001N, a polyethylene glycol‐conjugated bilirubin 3α nanoparticle, is the first GMP‐grade, synthetic bilirubin‐based nanomedicine. It effectively attenuates acute renal injury, facilitates subacute renal recovery, and suppresses chronic fibrosis after renal ischemia/reperfusion injury via anti‐oxidant and immune‐modulating activity.
