Unity Quantum Yield of High‐Entropy Quantum Dots Composited With Photonic Crystals for Information Encryption

Advanced Science, EarlyView.
This study first extends the high‐entropy concept to I‐III‐VI quantum dots (QDs) and synthesizes CZCrGSe/ZnSe/ZnS core/shell/shell QDs with a record photoluminescence quantum yield (PLQY) of 100%. Their ZnSe/ZnS double shell efficiently passivates defects and boosts structural stability.

Herba Lysimachiae Polysaccharide‐Modified Selenium Nanoparticles Alleviate Oxidative Injury in Kidney Stones via TOMM22‐Regulated Mitophagy Activation

Advanced Science, EarlyView.
HLP‐SeNPs, a Lysimachia christinae polysaccharide‐modified selenium nanoparticle, treat kidney stones by downregulating TOMM22 expression, which reduces PINK1 translocation into mitochondria and promotes its retention on the outer mitochondrial membrane.

Immobilization of Chymotrypsin on Selenium Nanoparticles

, 2017
In the present study, selenium nanoparticles (SeNPs) were prepared via selenious acid reduction with ascorbic acid in aqueous media and used for immobilization of hydrolytic enzyme chymotrypsin (CT). It was shown that CT is an effective stabilizer of SeNPs in solution at acidic pH values.

Inhibition of KDEL Receptors Remodels the Tumor Microenvironment for T Cell Independent Tumor Regression

Advanced Science, EarlyView.
Inhibition of KDELR2 in a small fraction of tumor cells generates sustainable immunogenic cell death conditions within the tumor microenvironment. These conditions promote the regression of tumors in a T cell independent manner. During regression, macrophages prime T cells that subsequently provide systemic protection against recurrence. The potency of

Unveiling a Hidden Conversion Pathway in CoSe2 Anodes via Rationally Designed CNT‐Interwoven Hollow Carbon Microclusters for High‐Performance Potassium‐Ion Batteries

Advanced Science, EarlyView.
A rational architectural design of hierarchical, CNT‐interwoven hollow carbon microclusters unlocks and stabilizes a unique monoclinic Co3Se4‐mediated conversion–insertion pathway for potassium storage. This structural confinement effectively guides the reaction kinetics and accommodates severe mechanical strain.
