Flexible, Integrated‐Porous Microneedle Sensor for Biofluid Sampling and On‐Site Biomarker Detection

Advanced Materials Technologies, EarlyView.
A paper‐integrated porous PGA microneedle array patch capable of both high strength and absorption capacity is proposed. With an image‐processing system, an optimized colorimetric sensor achieves a low limit of detection of 0.09 mm in cholesterol.

Eliminate the contradiction between temperature and toughness by grain-boundary delamination in heterogeneous ultrafine-grained lamellar steels

Materials Research Letters
Heterostructured ferritic steels with bimodal-grained lamellar (BG-L) and ultrafine-grained lamellar (UFG-L) microstructure were prepared through a warm deformation process. The BG-L steel exhibits enhanced mechanical properties compared to conventional quenched and tempered (QT) steel.

Recyclable and Binder‐Free EGaIn–Carbon Liquid Metal Composite: A Sustainable Approach for High‐Performance Stretchable Electronics, Thermal‐Interfacing and EMI‐Shielding

Advanced Materials Technologies, EarlyView.
Binder‐free EGaIn–CB composite deliver printable, recyclable liquid‐metal conductors without sintering or polymer binders. Only 1.5 wt% CB yields shear‐thinning, high‐viscosity rheology, ∼60% bulk EGaIn conductivity, robust stretchability, high thermal conductivity, and strong EMI shielding (35 → 70 dB at 100% strain).
