Membrane Semi‐Permeability and Ion Selectivity in Chemiosmosis: Open Systems Volume Dependence of Electrolyte Chemistry

Advanced Materials Interfaces, EarlyView.
Very small cellular compartments can break electroneutrality and harness proton gradients without active transport structures, whereas larger volumes cannot, underscoring why life's critical energy processes are confined in microscopic spaces. ABSTRACT The effect of pH changes in external ionic solutions on liposomes entrapping non‐permeable weak acid ...

Rational Design of Optical Single‐Walled Carbon Nanotube‐Based Nanosensors with Biological Recognition Elements

Advanced Sensor Research, EarlyView.
This Review focuses on assessing and providing perspective on the field of rationally‐designed optical sensors constructed with single‐walled carbon nanotubes. The literature is reviewed and evaluated for SWCNT‐based sensors constructed with biomolecular recognition elements, including proteins, peptides, and oligonucleotides, as well as their methods ...

Dual Co/Photoredox‐Catalyzed Regio‐ and Stereoselective Synthesis of Highly Functional 1,3‐Dienes

Angewandte Chemie, Volume 138, Issue 6, 2 February 2026.
A generic regio‐ and stereoselective protocol for the synthesis of functionalized 1,3‐dienes is presented that is facilitated via a dual Co/photoredox catalyst system while using modular 1,3‐enynes and unsaturated carbonyl derivatives as substrates. Key to the success of this transformation is the generation of a Co(III)H species that adds to the 1,3 ...

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

Advanced 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 ...

Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.

Directed Charge Transfer‐Driven Efficient Photocatalytic Hydrogen Production in Dual S‐Scheme WS2/Co9S8/ZnCdS Heterojunction

Carbon Energy, EarlyView.
The photocatalytic hydrogen evolution reaction (HER) activity of the polyoxometalate (POM)‐derived dual S‐scheme heterojunction photocatalyst WS2/Co9S8/ZnCdS reaches a value as high as 15.66 mmol g−1 h−1 under visible light (λ ≥ 420 nm), providing a straightforward approach for the development of dual S‐scheme heterojunctions to enhance the efficiency ...
