Mechanism‐Driven Nanoformulations for Cognitive Impairment Induced by Intermittent Hypoxia and Periodontitis

Advanced Materials, EarlyView.
Clinically, intermittent hypoxia (IH) is often accompanied by periodontitis, which accelerates cognitive impairment induced by IH. Novel Janus mesoporous gold‐silica nanoformulations (RVG‐Au&mSiO2‐TPP‐VB) enable intranasal delivery, achieve hierarchical targeting to neuronal mitochondria, effectively scavenge reactive oxygen species, inhibit the HIF‐1α/

A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.

Effect of inert gas injection parameters on explosion suppression of H2-CH4 mixtures

Gong-kuang zidonghua
To investigate the effect of inert gas injection parameters on the explosion characteristics of H2-CH4 mixtures, experiments were carried out in a horizontal pipeline to study the suppression of H2-CH4 mixture explosions by N2 and CO2.

A Wireless, Passive Multimodal Wearable Sensor With Decoupled Sensing Capabilities

Advanced Materials, EarlyView.
A wireless passive multimodal electronic skin is presented for the simultaneous perception of pressure, humidity, and odor through a frequency‐divided LC resonator array. The decoupled sensing architecture suppresses cross‐interference and enables independent signal readout under superimposed stimuli while maintaining high stability.

Coupled Quantification of Physical and Chemical Inhibition Effects of N₂ and CO₂ on NH₃/H₂/air Explosions

Hydrogen
This study investigates the explosion suppression of N2 and CO2 on NH3/H2/air mixtures (NH3:H2 = 4:6, φ = 0.6–1.5) in a 5 L constant volume chamber. Results show that CO2 exhibits superior efficacy compared to N2.
