Char to the Rescue: Processing and Transfer of Flame‐Retardant Epoxy Resins, Adjusting the Fire Behavior and Post‐Fire Structural Integrity of Glass Fiber Composites

Journal of Polymer Science, Volume 63, Issue 20, Page 4295-4309, 15 October 2025.
A comparison of the residual post‐fire flexural strengths of DGEBA and epoxy novolac composites with and without flame retardants. ABSTRACT Epoxy (EP) glass fiber reinforced composites (GFRCs) are extensively used in structural applications due to their excellent thermal and mechanical properties, but their inherent flammability limits fire‐safe ...

Depth‐Customizable 3D Electrode Array for Recording Functional Connectivity in the Brain

Advanced Electronic Materials, Volume 11, Issue 13, August 20, 2025.
In this study, a depth‐adjustable, flexible 3D multi‐shank electrode array that produces precise neural recordings at various brain depths is developed. Integrating 2D flexible electrode arrays with a modular supporting board allowed the insertion depth to be easily adjusted without re‐fabrication.

Oxidation Behavior of MgO‐C Refractories Containing Metallic Aluminum, Calcium Magnesium Aluminate Aggregates, and Carbores P

steel research international, Volume 96, Issue 5, May 2025.
The study investigates the oxidation resistance of MgO‐C refractories enhanced with calcium magnesium aluminate (CMA) aggregates, metallic aluminum, and Carbores P from 800 to 1600 °C. CMA retains resistance up to 1200 °C but decreases above. Carbores P protects up to 1000 °C, while metallic aluminum shows the highest resistance across the range.

Effect of Tetrapropylammonium Chloride Quaternary Ammonium Salt on Characterization, Cytotoxicity, and Antibacterial Properties of PLA/PEG Electrospun Mat

Biopolymers, Volume 116, Issue 1, January 2025.
ABSTRACT In this study, poly(lactic acid) (PLA)–tetrapropylammonium chloride (TCL)–poly(ethylene glycol) (PEG) nonwoven networks were produced using PLA, PEG with different concentrations (3, 5, 7, and 9 wt%), and TCL. PEG is included as a plasticizer in PLA polymer, which has high biocompatibility but a brittle structure.
