Electro‐Steric Ion Confinement in Polyelectrolyte Networks for Robust Nonvolatile Artificial Synapse

open access: yesAdvanced Functional Materials, EarlyView.
Polyelectrolyte stoichiometry governs ion transport and retention in electrolyte‐gated synaptic transistors. A PSS‐rich network creates electro‐steric ion confinement that suppresses ion back‐diffusion and stabilizes channel doping, enabling robust nonvolatile synaptic memory, linear weight updates, and low‐energy operation.

A Holistic Stabilization of the Anode in Lithium‐Sulfur Batteries Through a Ternary Alloy Fusion

open access: yesAdvanced Functional Materials, EarlyView.
LiTeAl anodes fabricated through a scalable thermal fusion technique holistically addresses the stability issues faced by lithium‐metal anodes in lithium–sulfur batteries. Aluminum forming a skeletal network with lithium suppresses dendrite growth and enhances energy density, while tellurium forming a robust SEI facilitates Li+‐ion flow.

Injection Molding of SUS316L Powder with Polyacetal.

open access: yesJournal of the Japan Society of Powder and Powder Metallurgy, 1993
Injection molding of metal powder with use of POM(polyacetal) was discussed.The compound on this process consisted essentially of POM and depolymerization polymers. It was clearly that the rate of degradation of the compound which contains a good deal of polyacetal was faster than that of which contains a good deal of other depolymerization polymers ...

Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

open access: yesAdvanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...

Tuning Amorphous‐Crystalline Catalytic Interfaces by Mechanochemistry: Cu‐Based Metallic Glasses Coupled with Ceria for CO Oxidation

open access: yesAdvanced Materials, EarlyView.
Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.
