Electrochemically Modified Mn₂P₄O₁₂ as an Emerging Catalyst for Oxygen Evolution Reaction

Advanced Materials Interfaces, EarlyView.
Mn₂P₄O₁₂ nanomaterials derived from MnO₂ nanosheets, act as pre‐catalysts and undergo in situ surface reconstruction during alkaline OER. The transformation yields MnO₂ and restructured Mn₂P₄O₁₂ phases, forming efficient active sites. This work highlights cyclotetraphosphate‐based catalysis and introduces a cost‐effective, stable material for enhanced ...

Reconfigurable Soft Actuators Constructed via Layer‐by‐layer Assembly

Advanced Materials Interfaces, EarlyView.
Stimulated by the energy inputs from heating or humidifying, structural reconfigurations took place in two different materials as manifested by the dynamic structures and mechanical performance, leading to the opportunities of self‐healing and welding. Based on the hierarchical assembly of these two materials with complementary properties, an actuator ...

Vertical Membrane‐Free Organ‐on‐a‐Chip for High‐Throughput In Vitro Studies and Drug Screening

Advanced Materials Technologies, EarlyView.
This novel microfluidic organ‐on‐a‐chip (OoC) platform enables cost‐effective, high‐throughput in vitro modeling. With vertical compartmentalization and gravity‐driven flow, it eliminates porous membranes and external pumps. Successfully generating intestine, cartilage, and tendon models, this study demonstrates drug responses, including 5‐fluorouracil

Observation of Laser Cooling on an Electric‐Dipole‐Allowed Transition in Cr3+:LiSAF Crystal

Advanced Optical Materials, EarlyView.
In this work, an electric dipole allowed transition in Cr3+:LiSAF crystals is investigated for the purpose of optical refrigeration. A cooling efficiency approaching 10% is experimentally determined using a mode‐mismatched dual‐beam thermal lens method with 1 µm excitation in an unoriented 1% Cr3+:LiSAF sample.

Microlasers Made Entirely from Edible Substances

Advanced Optical Materials, EarlyView.
Several types of microlasers made completely out of edible substances are developed. They can be embedded directly into edible products and enable the sensing of various parameters, including sugar concentration, pH, the presence of bacteria, and exposure to too‐high temperatures.

Regio‐, Stereoselective, Aerobic and Metal‐Free Synthesis of Z‐Vinyl Sulfides: One‐Pot Hydroiodination of Internal Alkynes and in situ Sulfenylations

Advanced Synthesis &Catalysis, EarlyView.
Abstract A novel, metal‐free, air‐ and moisture‐compatible one‐pot tandem protocol for the regio‐ and stereoselective synthesis of Z‐vinyl sulfides (achieving yields up to 99%), is reported. This straightforward and efficient process combines the selective hydroiodination of internal alkynes, promoted by the eutectic mixture choline iodide (ChI)/p‐TsOH

Epileptiform Activity and Seizure Risk Follow Long‐Term Non‐Linear Attractor Dynamics

Advanced Science, EarlyView.
This study leverages the HAVOK framework to model long‐term, nonlinear attractor dynamics underlying epileptiform activity and seizure risk in epilepsy patients. By identifying key forcing mechanisms driving chaotic transitions, the findings improve seizure risk forecasting over multi‐day cycles and provide a pathway for personalized, data‐driven ...

A Reversible and Dynamic Surface Functionalization for Fluidity Controlled Multivalent Recognition of Lectins and Bacteria

Advanced Science, EarlyView.
A reversible wet chemical surface functionalization results in dynamic multivalent receptors showing ligand‐specific high affinity for lectins and bacteria. Abstract The paper reports the design of multivalent bacterial receptors based on reversible self‐assembled monolayers (rSAMs) on gold and glass substrates, mimicking the ligand display on host ...

Electrically Tunable Momentum Space Polarization Singularities in Liquid Crystal Microcavities

Advanced Science, EarlyView.
Using a highly birefringent material embedded in a liquid crystal microcavity, the Rashba‐Dresselhaus resonance is obtained. In this regime, polarization singularities, known as C‐points, are observed in momentum space. The positions of these singularities can be modified by applying an external voltage to the sample.
