A Novel Co3O4@Co3(HITP)2‐Based Sensor for Low‐Temperatures H2S Detection: Fabrication, Performance, and Preliminary Exploration in Monitoring Pork Spoilage

open access: yesAdvanced Science, EarlyView.
Hybrid Co3O4@Co3(HITP)2‐based chemiresitor was constructed for hydrogen sulfide detection at low‐temperature, which presented excellent sensing performance at room and refrigerant temperature. A proof of concept was conducted by monitoring hydrogen sulfide released from pork spoilage at both temperature using a portable device with a smartphone ...

Monitoring and modeling of household air quality related to use of different Cookfuels in Paraguay. [PDF]

open access: yes, 2019
In Paraguay, 49% of the population depends on biomass (wood and charcoal) for cooking. Residential biomass burning is a major source of fine particulate matter (PM2.5 ) and carbon monoxide (CO) in and around the household environment. In July 2016, cross-

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

open access: yesAdvanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Dual‐Responsive Yarn‐Based Artificial Muscles for Adaptive Thermal Management

open access: yesAdvanced Science, EarlyView.
Inspired by the conscious movements of skeletal muscle, a novel hybrid yarn‐based artificial muscle (HYAM) coupling moisture actuation with controllable recovery is developed. This unique design increases actuation stroke by 128% and shortens recovery time by 91%. This unique design enhances the actuation stroke by 128% and reduces the recovery time by
