Combined Effects of Thermal Cycling Aging and Reinforcement Content on the Ball‐On‐Disk Wear of Additively Manufactured Polylactic Acid Composites

Polymer Composites, EarlyView.
Thermal Aging and Tribological Tests of Additive Manufactured PLA Composites. ABSTRACT This study focuses on the additive manufacturing of pure polylactic acid (PLA) specimens and milled glass fiber (GF)‐filled PLA composites under thermal cycling aging and wear tests. Wear tracks have been analyzed via 3D optical profiling and SEM imaging.

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

High Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...

Achieving Ultra‐Low Megahertz Loss in Nanocrystalline Magnetic Powder Cores via Alloy Design and a Self‐Healing Organic–Inorganic‐Derived Hybrid Insulating Layer

Advanced Chemical Engineering, Volume 1, Issue 2, December 2026.
A novel self‐healing FePO4/B2O3/epoxy hybrid insulating layer is designed for high‐frequency Fe‐based nanocrystalline magnetic powder cores. During 530°C annealing, the low‐melting‐point B2O3 softens, flowing into micro‐cracks formed within the brittle FePO4 framework during cold pressing. This in situ gap‐filling mechanism effectively suppresses inter‐
