Stabilizing Frustrated Phase Transitions in Selective Oxidation Reactions

Advanced Materials, Volume 38, Issue 8, 6 February 2026.
Using multimodal operando spectromicroscopy, the frustrated phase transition responsible for selective oxidation over cobalt oxide spinel catalysts is identified, corresponding to combined surface reaction and Mars‐van Krevelen (MvK) dynamics. This regime is disrupted by the formation of mobile vacancies and the depletion of active oxygen at high ...

Oxygen‐Regulated GaN‐Based Sensors Fabricated by MOCVD for Switchable Gas Detection: Exhaled Gas Smart Platform for Non‐Invasive Disease Detection

Advanced Science, Volume 13, Issue 7, 3 February 2026.
This work presents highly consistent GaN‐based thin‐film gas sensors prepared by MOCVD for non‐invasive breath analysis. The sensors exhibit tunable selectivity from oxidizing to reducing gases by incorporating In composition, ultra‐low detection limits and humidity resistance.

Investigating the Fate of Geosmin on Microalgal Cells: A Comprehensive Study on Adsorption and Desorption Processes

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Microalgal biomass has emerged as a valuable resource in recirculating aquaculture systems (RAS), due to its natural capacity to recover nutrients. In addition, microalgae are potential source of fish‐feed in the aquaculture industry. However, its application in RAS needs careful consideration, as microalgae can interact with geosmin, a common

Guanidinium Like‐Charge Ion Pairing and Oligoarginine Aggregation in Water by Nuclear Magnetic Resonance, Cryo‐Electron Microscopy, and Molecular Dynamics

Aggregate, Volume 7, Issue 2, February 2026.
This study shows that guanidinium cations weakly attract one another in water and form like‐charge contact ion pairs. From NMR, we determine the free energy of ion‐pair formation to be ≈${\approx }$ –0.5 kJ mol−1${\rm mol}^{-1}$, consistent with all‐atom MD simulations and DFT calculations.

Low Parsons–Zobel slope of metal–solution interfaces: A theoretical comparison of three causes

AIChE Journal, Volume 72, Issue 2, February 2026.
Abstract Rational design of electrochemical energy conversion and storage devices hinges on a fundamental understanding of the electrical double layer (EDL) at the electrode–electrolyte interface. The classical Gouy–Chapman–Stern model of EDL predicts a unity Parsons–Zobel (PZ) slope, which is derived from the relation between inverse measured ...
