The biocompatibility of a novel polyether ether ketone (PEEK) stoma device with human epidermal keratinocytes [PDF]

Surgical stomas are essential interventions for many medical conditions, however, can create physical complications, such as peristomal skin irritation. Medical stoma devices (MSD) are a potential treatment to mitigate such complications. Polyether ether

Using a Zero‐Strain Reference Electrode to Distinguish Anode and Cathode Volume Changes in a Solid‐State Battery

Advanced Materials Interfaces, EarlyView.
Volume changes of a solid‐state battery cell are separated into the individual contributions of anode and cathode. Simultaneously determining the “reaction volumes” of both electrodes requires a reference electrode with a pressure‐independent potential.

In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

Advanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Enhanced mechanical, thermotolerance, and anti-yellowing performance of glass fibre filled polyether-ether-ketone composites with enclosed polyether-ether-ketone polyamide acid sizing agent

Materials & Design
The application potential of glass fiber reinforced polyether-ether-ketone (GF/PEEK) composites is hampered by weak interfacial adhesion. This problem originates from the low wettability and the thermal decomposition of the interlayer at high ...

Oxygen‐Driven Structural Reorganization by Trace Water Enabling Fast Li‐Ion Transport in a Pliable Solid Electrolyte

Advanced Energy Materials, EarlyView.
Trace water is acting as a constructive mediator in 2LiCl–GaF3, markedly increasing ionic conductivity while reorganizing local coordination. Hydration creates localized Li+ solvation environments and partially dissociates ion pairs, enhancing Li‐ion mobility.

Investigation of Moisture‐Induced Degradation Mechanisms and a Reviving Strategy for Sulfide‐Based Solid Electrolytes in All‐Solid‐State Composite Cathode

Advanced Energy Materials, EarlyView.
Moisture exposure induces the formation of reductive solid phases on argyrodite Li6PS5Cl, which destabilize Ni‐rich cathodes by extracting lattice oxygen and inducing surface reconstruction. A brief oxygen‐assisted annealing treatment quenches these reductive phases, restores interfacial stability, and enables effective regeneration and reuse of ...
