Nb2C‐Reinforced Hydrogel Microneedle as Dual ROS‐Scavenging Platform to Promote Diabetic Wound Healing

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 15, 17 April 2026.
An advanced microneedle patch integrating niobium carbide nanosheets and curcumin is engineered for diabetic wound healing. The system enables dual ROS scavenging and NIR‐enhanced antimicrobial activity, effectively rebalancing the oxidative microenvironment, promoting macrophage repolarization and angiogenesis, and accelerating full‐thickness wound ...

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

open access: yesAdvanced Materials, Volume 38, Issue 20, 7 April 2026.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Ellipsometry Optical Gas Sensor of SnO2/Porous‐Si Heterostructure for Organic Compounds Detection

open access: yesAdvanced Sensor Research, Volume 5, Issue 4, April 2026.
ABSTRACT This study presents a low‐temperature optical gas sensing platform based on tin dioxide (SnO2) thin films deposited on porous silicon (por‐Si) substrates. The por‐Si scaffold was fabricated electrochemically, followed by SnO2 deposition via RF magnetron sputtering.

Ejecta‐Modulated Bubble Dynamics Play a Dominant Role in Stone Retropulsion

open access: yesAdvanced Science, Volume 13, Issue 22, 17 April 2026.
Stone motion during laser ablation is shown to result primarily from asymmetric cavitation bubble collapse, not from ejecta recoil. This challenges long‐standing assumptions and highlights the dominant role of bubble dynamics in laser–material interactions.
