Opposite Trends in Glass Transition and Vogel Temperatures in Long‐Chain Branched Poly(l‐Lactic Acid)

Journal of Polymer Science, EarlyView.
The glass transition temperature (Tg), as determined by conventional DSC, increases from 326 K to 329 K while the Vogel temperature (Tv) decreases from 271 K to 255 K as the number of branch points per molecule increases from 0 to 3.3. ABSTRACT Poly(l‐lactic acid) (PLLA) is widely used as both a commodity thermoplastic and for engineering applications,

Validation of Electrostrictive Performance of P(VDF‐TrFE‐CFE) for kHz Range Applications

Journal of Polymer Science, EarlyView.
This study demonstrates that the high‐frequency deformation of the relaxor ferroelectric polymer P(VDF–TrFE–CFE) is governed by Maxwell's electrostriction, confirming its suitability for fast electromechanical applications. Combining original high‐frequency mechanical characterization, laser vibrometry measurements, and numerical modeling, a ...

Theoretical Analysis of Androstenone Adsorption on Chimpanzee and Gorilla Olfactory Receptors (G‐Protein): Statistical Physics Modeling, Molecular Docking Simulation, and Thermodynamic Investigation

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT An advanced theory based on statistical physics was applied to microscopically investigate androstenone adsorption and its relationship with olfactory perception in chimpanzees and gorillas. For this purpose, dose–response curves of androstenone on olfactory receptors of chimpanzee OR7D4 and gorilla OR7D4 were analyzed by statistical physics ...

Super‐capacitive carbon materials with large micropores and rich mesopores synthesized using N, S co‐doped carbon dots as self‐templates

Responsive Materials, EarlyView.
Nitrogen‐sulfur co‐doped carbon dots are employed as self‐templates to fabricate hierarchical porous carbon material with a concentrated micropore size distribution of 1.1–1.6 nm and a high mesopore volume ratio up to 47.2%, which shows good capacity and excellent responsive ability as electrodes in electrochemical supercapacitors.

Mixed TiO2–SiO2 thin coatings for selective adsorption and sunlight‐powered photodegradation of cationic pollutants

Responsive Materials, EarlyView.
Environmental pollution and water scarcity demand innovative purification methods. This study presents a sol‐gel approach to fabricate mixed silica–titania thin films joining photocatalytic activity with selective sorption capability. The films exhibit higher surface area, enhanced degradation of cationic and improved performance over bare titania ...
