Carbon‐Modified SnS2/g‐C3N4 S‐Scheme Heterostructure with Enhanced Interfacial Charge Transfer for Efficient Photocatalytic Reduction of Cr(VI) and 4‐Nitrophenol

open access: yesSmall, EarlyView.
The S‐scheme of SnS2‐C/g‐C3N4 heterostructure enables Photocatalytic Cr(VI) and 4‐NP reduction. ABSTRACT Hexavalent chromium (Cr(VI)) and 4‐nitrophenol (4‐NP) are persistent and highly toxic water pollutants that require efficient treatment under mild conditions. In this work, L‐cysteine‐derived carbon‐modified SnS2 (SnS2‐C) was prepared hydrothermally

A Dynamic Surface Metal‐Organic Framework Electrocatalyst: Potential‐Driven Activation of Atomically Defined Au Sites for the Hydrogen Evolution Reaction

open access: yesSmall, EarlyView.
Operando EC‐STM reveals that an NHC‐based SMOF on Au(111), initially frozen in interconnected 1D chains, dynamically reconfigures under cathodic bias into a fluxional structure bearing undercoordinated Au sites while abstracting Au atoms from the support.

Bioelectronic Wearable Sensors Produced by Computerized Embroidery Using a Dual Thread Approach

open access: yesSmall, EarlyView.
A dual‐thread embroidered SmartBra integrates silver‐plated and conductive‐polymer (PECOTEX) threads to enable simultaneous cardiac monitoring and open‐circuit potentiometric sensing of potassium and sodium in a breast milk substitute. The wearable platform is fabricated using computerized embroidery, offering a scalable, proof‐of‐concept route toward ...

Parallelized 61‐Sample Inhibition Screening Accelerated by 19F‐MRI Compressed Sensing

open access: yesSmall Methods, EarlyView.
One scan, swift answers: a 19F‐MRI honeycomb captures reporter ligand displacement across dozens of non‐fluorinated drug candidates in parallel. Miniaturized arrays with compressed sensing speed up acquisition, delivering rapid, quantitative readouts for ligand screening.

Accomplishing Ethics‐Work as a Generic Social Process

open access: yesSymbolic Interaction, EarlyView.
Existing systems of university research ethics are often criticized by those in the qualitative research tradition. A common thread is that ethics cannot be fully anticipated before the research begins, as is expected by most institutional review boards.
