Balanced Fire Safety and Mechanical Integrity in Thermoplastic Polyurethane via a Synergistic Ternary System of Hydromagnesite andMicroencapsulated Additives

ABSTRACT To mitigate the trade‐off between flame retardancy and mechanical performance in thermoplastic polyurethane (TPU), an optimized ternary flame‐retardant formulation consisting of hydromagnesite (HM), microencapsulated red phosphorus (MRP), and microencapsulated expandable...

Design, Modeling and Performance Analysis of an Actively Variable Stiffness Pneumatic Flexible Bending Joint

The contradiction between high compliance and low load-bearing capacity of flexible manipulators limits their engineering applications. Meanwhile, the theoretical modeling of the deformation and variable stiffness characteristics of flexible joints still faces considerable challe...

Wholly bio-based hyperbranched waterborne polyurethane coatings reinforced with surface-engineered cellulose nanofibers for sustainable wood protection

Bio-based waterborne polyurethane (BWPU) coatings have drawn attention as renewable alternatives to petroleum-based wood finishes for Larix gmelinii , yet their mechanical strength, hardness, and barrier properties remain insufficient for demanding applications. In this work, cel...

Climatic Suitability of Cornus officinalis Across Paleoclimatic, Current, and Future Climates: Implications for Conservation and Climate-Informed Cultivation

Cornus officinalis Sieb. et Zucc. is a medicinal and ornamental woody plant whose distribution and production may be increasingly affected by climate change. This study assessed its climatic suitability under paleoclimatic, current, and future conditions to provide a climatic bas...

Ultra Broad Range Pressure Tunable CaZrO3:Ce3+ Luminescence for Multiparametric Manometry

Optical manometry is essential in diamond anvil cell experiments, motivating pressure-sensitive phosphors that provide robust broadband readouts over a wide pressure range. Here we report a Ce3+-activated CaZrO3 perovskite phosphor with a low dopant level of about 0.40 atom % Ce...

Laccase-Inspired Cu–POM Catalysts with Support-Regulated Interfaces for Oxidative Depolymerization of Lignin

Abstract Lignin is the only abundant renewable aromatic polymer in nature and is therefore an important feedstock for the sustainable production of aromatic chemicals and functional materials. Its selective depolymerization, however, remains difficult because of the structural he...

Preparation and performance of non‐toxic silica sol/melamine‐glyoxal composite dye modifier for staining fast‐growing poplar

Abstract To address the poor mechanical strength and surface color of fast‐growing poplar wood, and to avoid the environmental hazards posed by formaldehyde emissions from resin‐based dyeing modifiers, a composite modifier was formulated in this study. This modifier was fabricate...
