Quantum Chemical Properties of Fluorouracil/XZn11O12 (X = Zn, Cu, Fe, Ni) Nanocomplexes and Interactions with Human Serum Albumin

open access: yesChemistryOpen, Volume 15, Issue 3, March 2026.
Adsorption of fluorouracil (5‐FU) on XZn11O12 (X = Zn, Cu, Fe, Ni) nanoclusters and its interactions with human serum albumin (HSA) have been studied using density functional theory and molecular docking. Reduced HOMO‐LUMO gap of 5‐FU@NiZn11O12 nanocomplex suggests enhanced charge transfer activity.

Exclusive Se‐O Coordination and Fe‐doping Complementation: A Catalytic Strategy for Enhanced Sulfur Redox in Li‐S Batteries

open access: yesAdvanced Science, Volume 13, Issue 9, 13 February 2026.
Exclusive Se‐O coordination and Fe‐doping complementation significantly improve conductivity and modulate the d‐band centers, which strongly anchor polysulfides in bidirectional catalysis and reduce the energy barriers for the Li2S nucleation and dissociation, achieving high‐apacity retention, exceptional rate capability, and stable cycling capability.

Room Temperature Fabrication of Binder‐Free Na3V2(PO4)3/C High‐Loading Electrode Films via the Powder Aerosol Deposition Method

open access: yesBatteries &Supercaps, Volume 9, Issue 2, February 2026.
Na3V2(PO4)3/C cathodes were fabricated on Al substrates via powder aerosol deposition and compared with tape‐cast electrodes. Despite high active‐material loading, powder aerosol deposition (PAD) films show limited utilization due to dense microstructure–restricted ion transport.
