Designing Scalable Mechano‐Virucidal Nanostructured Acrylic Surfaces for Enhanced Viral Inactivation

open access: yesAdvanced Science, EarlyView.
Can a surface be designed to physically break viruses? This study explores how nanoscale geometry—specifically the spacing of tiny pillars—can determine whether viruses remain intact or rupture. Using flexible acrylic and a scalable fabrication process, the authors develop nanopillared, transparent surfaces that show strong antiviral activity without ...

Pacinian Corpuscle‐Inspired Strain Conversion Enables Ultrasensitive, Linear, and Broad‐Range Piezoelectric Sensing for Cardiovascular Health Monitoring

open access: yesAdvanced Science, EarlyView.
A bioinspired piezoelectric sensor mimicking Pacinian corpuscles is developed to enable ultrasensitive and linear pressure sensing. A multilayer grooved architecture converts normal pressure into in‐plane strain, delivering high sensitivity, wide linear range, and efficient energy harvesting, enabling high‐fidelity wrist pulse monitoring and ...

Mutability and importance of a hypermutable cell subpopulation that produces stress-induced mutants in Escherichia coli.

open access: yesPLoS Genetics, 2008
In bacterial, yeast, and human cells, stress-induced mutation mechanisms are induced in growth-limiting environments and produce non-adaptive and adaptive mutations.

Endometrial Epithelial Lactate Deficiency Drives CD8+ T‐Cells Dysregulation in Unexplained Recurrent Implantation Failure

open access: yesAdvanced Science, EarlyView.
Unexplained recurrent implantation failure (RIF) represents a significant clinical challenge. Our results demonstrate that reduced lactate production in the RIF endometrium impairs the suppression of cytotoxic CD8+ T‑cells, allowing their proliferation and thereby disrupting the local immune balance essential for successful embryo implantation.

Tuning Defects in Ni‐Doped Maghemite for Enhanced Solar Driven Oxygen Evolution: Insights From Operando X‐Ray Spectroscopies

open access: yesAdvanced Science, EarlyView.
ABSTRACT Maghemite (γ$\gamma$‐Fe2${\rm Fe}_2$O3${\rm O}_{3}$) is a promising non‐precious‐metal‐containing photocatalyst for water oxidation (OER). Despite being less studied than Hematite, it offers similar corrosion resistance and a favorable band structure, along with higher conductivity and the advantage of an adaptable spinel structure.

Ultrafast Interfacial Engineering for Quantifiable Control of Asymmetric Configurations in Nanostructured Janus Membranes

open access: yesAdvanced Science, EarlyView.
Founded on a rapidly formed nanostructured tannic acid/polyethyleneimine (TA/PEI) platform, an ultrafast (∼5 min), universal interfacial engineering strategy utilizing stearoyl chloride (SC) and Phytic acid (PA) enables precise fabrication of Janus membranes across diverse substrates.

Small‐Molecule Activation of mRNA Translation by Click‐to‐Release Reaction in Cells

open access: yesAngewandte Chemie, EarlyView.
A new method to control mRNA activity using bioorthogonal click‐to‐release reactions is presented. The 5′ cap is modified with a trans‐cyclooctene (TCO) that quickly reacts with hydroxyaryl‐tetrazines and efficiently releases the native cap 0. TCO‐capped mRNAs are initially translationally inactive but can be activated with non‐toxic, cell‐permeable ...

Robust and Thermally Stable Silicone Aerogels with Hyperconnected Network via Kinetically Optimized Hyperbranched Silane Precursors

open access: yesAdvanced Science, EarlyView.
Reactivity‐Programmed Assembly: A kinetic‐control strategy is reported for constructing hyperconnected silicone aerogels with a robust “thick‐neck” architecture. By exploiting the reactivity disparity of precursors, flexible segments are uniformly embedded within a rigid skeleton.

Fabrication of Composite Cathode for All‐Solid‐State Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
The design of composite cathodes for all‐solid‐state sodium batteries must address three critical challenges—interfacial side reactions, interfacial delamination, and highly tortuous transport pathways. This work outlines structural and interfacial strategies to optimize ion transport and mechanical stability, enabling durable, and high‐performance ...
