Smart Gated Hollow Mesoporous Silica Hydrogel for Targeting Endoplasmic Reticulum Stress and Promoting Periodontal Tissue Regeneration

open access: yesAdvanced Science, EarlyView.
The hollow mesoporous silica loaded with quercetin (HM‐QU@PEG) is combined with a thermosensitive anti‐bacterial matrix (TF127) to prepare HQUP@TF127. HQUP@TF127 effectively eliminates excessive ROS, alleviates endoplasmic reticulum stress, relieves mitochondrial calcium overload, and blocks the p53‐dependent apoptotic cascade. Furthermore, it enhances

A Degradable Bioinspired Flier with Aerogel‐Based Colorimetric Sensors for Environmental Monitoring

open access: yesAdvanced Science, EarlyView.
Biodegradable fliers are developed inspired by Tipuana tipu samaras, integrating cellulose nanocrystal aerogel (CNCa) sensors loaded with natural dyes for pH and ammonia detection. The lightweight, degradable fliers mimic natural morphology and aerodynamics, offering an eco‐friendly, scalable solution for in situ environmental monitoring after passive ...

Effects of Low Reynolds Number on Wake-Generated Unsteady Flow of an Axial-Flow Turbine Rotor

open access: yesInternational Journal of Rotating Machinery, 2005
The unsteady flow field downstream of axial-flow turbine rotors at low Reynolds numbers was investigated experimentally using hot-wire probes. Reynolds number, based on rotor exit velocity and rotor chord length Reout,RT, was varied from 3.2×104 to 12 ...

Learning to Navigate in Chemical Fields Without A Map at Low Reynolds Numbers

open access: yesAdvanced Science, EarlyView.
Deep reinforcement learning enables a reconfigurable artificial microswimmer to exhibit run‐and‐tumble strategy to navigate toward a chemical source. This mapless microswimmer can robustly navigate in diverse chemical fields without relying on a pre‐existing map.

Electrochemistry as a Tool for Redox‐Based Bio‐Information Processing

open access: yesAdvanced Science, EarlyView.
Redox is a modality that is native to biology and accessible to electronics through electrochemistry. Imposed electronic inputs are transduced into redox signals that can probe for bio‐information or actuate biological responses. Measured electronic output responses are analyzed to reveal actionable information.
