Molecular dynamics and COSMO-RS model of menthol–fatty acid deep eutectic solvents: thermodynamic, structural, and dynamics insights

Scientific Reports
Deep eutectic solvents (DESs) have emerged as sustainable alternatives to conventional solvents; however, our molecular-scale understanding of their intrinsic properties remains limited.

Experimental and Quantum Mechanical Studies of Efficient Re(VII)/Mo(VI) Separation by a Magnetic Amino-Functionalized Polymer

Separations
A previously synthesized and functionalized magnetic glycidyl methacrylate-based nanocomposite, mPGMT-deta, was tested as a sorbent for Re(VII) oxoanions in Mo(VI)-containing solutions. The effect of pH on the removal efficiency and the separation factor

Support‐Controlled Reaction Pathways via Dynamic Sulfur‐Mediated Interfaces for Selective Urea Electrolysis

Advanced Functional Materials, EarlyView.
Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...

Embedded Ferroelectric Nanoclusters Can Drive Polarization Reversal in a Non‐Ferroelectric Polar Film via the Proximity Effect

Advanced Functional Materials, EarlyView.
Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.

Synergistic Solar Interfacial Evaporation and Photocatalysis Enabled by a Hierarchical Porous Hydrogel Reactor

Advanced Functional Materials, EarlyView.
A tree‐inspired hydrogel interfacial reactor couples solar evaporation with photocatalysis for simultaneous desalination and waste water treatment. The bilayer design achieves 2.14 kg·m−2·h−1 evaporation rate with 79% dye degradation under one sun, demonstrating that photothermal heating and evaporation induced pollutant enrichment create a self ...

Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring

Advanced Functional Materials, EarlyView.
This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.

EFECTO DE ALGUNOS SOLVENTES ORGÁNICOS EN SATURACIÓN SOBRE LAS FUNCIONES TERMODINÁMICAS DE DISOLUCIÓN DEL NAPROXÉN EN MEDIOS ACUOSOS A pH FISIOLÓGICO EFFECT OF SOME ORGANIC SOLVENTS IN SATURATION ON THE THERMODYNAMIC FUNCTIONS OF DISSOLUTION FOR NAPROXEN IN AQUEOUS MEDIA AT PHYSIOLOGICAL pH

Vitae, 2007
El naproxén (NAP) es un anti-inflamatorio no esteroidal de amplio uso en la actualidad; sin embargo, sus propiedades fisicoquímicas aún no han sido totalmente estudiadas. Como una contribución a la caracterización fisicoquímica del NAP en solución acuosa,

Monolithic Oxidation Enables Ultrathin Vertically Graded Tantalum Oxide for Low‐Voltage, Low‐Variability Memristive Switching

Advanced Functional Materials, EarlyView.
Monolithic UV‐ozone oxidation of Ta forms an ultrathin Ta2O5/TaOx bilayer enabling resistive switching with a vertical defect gradient. A stoichiometric surface layer over an oxygen‐deficient sublayer promotes localized filament nucleation near the top interface, enabling low‐voltage operation, and reduced cycle‐to‐cycle variability.

Giant Electrostriction in Halide Perovskites Revisited With Double‐Modulation Interferometry

Advanced Functional Materials, EarlyView.
A giant electrostrictive effect in lead halide perovskites had been reported previously. This work uses sensitive interferometry to measure the electromechanical response of various halide perovskite samples. The results reveal no intrinsic electrostrictive compression. Instead, the materials expand primarily under an applied electric field as a result
