Biguanide Hydroiodide as Efficient, Metal‐Free Catalyst for Synthesis of Cyclic Carbonates From CO2 and Epoxides Under Mild Conditions and Its Application to Synthesis of Polymer Bearing Cyclic Carbonate Moiety

Journal of Polymer Science, EarlyView.
We developed that novel use of biguanides as catalysts for the efficient synthesis of five‐membered cyclic carbonates (5CCs) from CO2 and epoxides. Among biguanides and their salts, biguanide hydroiodide showed efficient catalysis for the 5CC formation under mild conditions (25°C–60°C and 1 atm of CO2).

Integrated Photo‐Rechargeable Batteries: Configurations, Design Principles, and Energy Loss Mechanisms

Small Science, EarlyView.
This review explores integrated photo‐rechargeable battery architectures that unify solar energy conversion with electrochemical storage. By analyzing two‐terminal, three‐terminal, and four‐terminal designs, this study reveals how the working mechanisms, materials, and energy loss pathways govern efficiency and propose design strategies. These insights

Polyaniline as a dual flame retardant and electrostatic dissipative additive in polyethylene nanocomposites

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 339-355, March 2025.
Effecft of co‐doping polyaniline with phosphoric acid and phytic acid on the heat release rate of polyethylene. Abstract Polyolefins, such as polyethylene (PE), are highly flammable and electrically insulative, limiting their applicability. The study explored the flame‐retardancy and electrical conductivity of PE/polyaniline (PE/PANI) nanocomposites ...

Hydrochlorothiazide combined with exercise training attenuates blood pressure variability and renal dysfunctions in an experimental model of hypertension and ovarian hormone deprivation

FASEB BioAdvances, Volume 7, Issue 4, April 2025.
Hydrochlorothiazide plus combined exercise training provides superior benefits compared to medication alone in female spontaneously hypertensive rats subjected to ovarian hormone deprivation. This combined approach significantly reduced blood pressure variability, improved inflammatory and redox profiles, and provided functional and morphological ...
