Enhancing the Mechanical Properties of Inherently Brittle, Biobased and Biodegradable Polyhydroxybutyrate (PHB) Polymer by Cotton Fibre Reinforcement and Interfacial Grafting

open access: yesAdvanced Sustainable Systems, EarlyView.
This study enhances biobassed, biodegradable polyhydroxybutyrate (PHB)s strength and ductility by reinforcing it with polyvinyl alcohol (PVA)‐coated cotton fibres and further improving interfacial bonding through maleic anhydride (MA) grafting. In addition to mechanical performance, the approaches significantly improve the gas barrier properties of the

Unusual Thermal Transport in Few‐Layer Van der Waals Antiferromagnet CrOCl

open access: yesAdvanced Science, EarlyView.
Thermal transport serves as an ultra‐sensitive probe for detecting the magnetic order in 2D materials. Using the suspended thermal bridge method enhanced by Wheatstone bridges, it is, for the first time, observed anomalous critical behavior in few‐layer CrOCl near its Néel temperature.

Energy‐Efficient Fabrication of Biomimetic Materials for Sustainable Infrastructure Applications

open access: yesAdvanced Science, EarlyView.
Inspired by nacre's “brick‐and‐mortar” structure, this work develops an energy‐efficient approach that utilizes ice‐templating technology as the structure framework and carbon mineralization for rapid CaCO3 production, resulting in a strong yet tough carbon mineralized material (CMM) under mild conditions while also fixing CO2.
