Negative electrode degradation induced by two-stage zinc plating and its recovery in zinc batteries

open access: yesNature Communications
Controlling the morphology of Zinc (Zn) deposits is an effective strategy to produce stable Zn-metal batteries. However, the degradation of Zn negative electrodes and changes in their morphology remain poorly understood. Here, we show that the Zn plating

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

open access: yesAdvanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Flexural Behavior of 3D‐Printed Porous Bouligand‐Structured Polymers: Influence of Pitch Angle and Porosity

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight

Binder-jet printing and pressure-controlled infiltration for fabrication of high-temperature, low-dead-volume microfluidic interfaces

open access: yesAdditive Manufacturing Letters
Interfacing is a consistent weak point in the manufacturing of microscale gas chromatography columns. Current techniques for interfacing with microfluidic systems often degrade under high temperatures and thermal cycling and suffer from dead volumes.
