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

Superior Electromechanical Power at Rare‐Earth Manipulated Glassy Morphotropic Phase Transitions

open access: yesAdvanced Science, EarlyView.
An effective physical approach named Rare‐earth Manipulated Glassy Morphotropic Phase Transitions has been experimentally developed and theoretically validated to achieve significant enhancements of 135% and 50% in electrostrain and elastic modulus of lead‐free ferroelectrics respectively, further enabling the significant boost of requisite driving ...

Designing Spin Symmetry for Altermagnetism with Strong Magnetoelectric Coupling

open access: yesAdvanced Science, EarlyView.
Antiferromagnets can be induced into altermagnets by changing the real‐space symmetry, increasing their potential for use in spintronic devices. Here, a novel and general approach is proposed: transforming antiferromagnets into altermagnets by modulating spin‐space symmetry, rather than real‐space symmetry.
