Multivalent Protein Nanorings for Broad and Potent SARS‐CoV‐2 Neutralization
A protein‐only, modular multivalent nanoscaffold displaying 20 anchor points, decorated with two different binders (10 of each), targeting the SARS‐CoV‐2 receptor‐binding domain is presented. The construct self‐assembles into stable, biocompatible, homogeneous nanoparticles, exhibit synergistic binding with fM IC50 values. It also detects spike at 9 ng

Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers
Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination

In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...
