Effect of Ammonium Polyphosphate/Silicate Content on the Postfire Mechanics of Epoxy Glass‐Fiber Composites Using Facile Chocolate Bar‐Inspired Structures

Fire and Materials, Volume 49, Issue 3, Page 329-346, April 2025.
ABSTRACT This study investigates the postfire mechanical properties of epoxy glass‐fiber reinforced composites (EP GFRCs) using increasing concentrations of ammonium polyphosphate (APP) and inorganic silicate (InSi) to modify the char and fire residue.

Mechanical Behaviour of Vacuum‐Infused GFRP Composites at Elevated Temperatures—Influence of Fibre Architecture

Fire and Materials, EarlyView.
ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...

Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin

Geological Journal, EarlyView.
Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.

Kinetic Investigation of Propylene Oxide Ring‐Opening Polymerization in a Multiphase Semibatch Reactor

Helvetica Chimica Acta, EarlyView.
A semi‐batch kinetic model for propylene oxide ring‐opening polymerization reveals that polymerization is governed by mass transfer at the catalyst–liquid interface rather than gas–liquid transport. ABSTRACT The multiphasic semi‐batch ring‐opening polymerization of propylene oxide was investigated with respect to mass‐transfer limitations at the solid ...

Curvature and Microenvironment Regulation Enable Robust Seawater Electrochemical Hydrogen Peroxide Synthesis for On‐Site Marine Aquaculture

Interdisciplinary Materials, EarlyView.
This work designs pentagon‐defect‐enriched interconnected spherical carbon (PD/IS‐C) via curvature and microenvironment co‐engineering for seawater H2O2 electrosynthesis. Curvature modulates electronic structure to boost reactivity, while local alkaline microenvironment repels Cl− for enhanced stability, endowing PD/IS‐C with exceptional catalytic ...
