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 ...

Lactiplantibacillus Plantarum GUANKE Alleviates Allergic Asthma by Restricting Monocyte‐to‐DC Differentiation Via Microbiota‐Associated IAA

open access: yesAdvanced Science, EarlyView.
Lactiplantibacillus plantarum GUANKE remodels the indigenous gut microbiota and is associated with microbiota‐dependent restoration of circulating IAA. IAA treatment attenuates JAK3‐STAT3 and Jag1‐Notch4‐Hey1 signaling and reduces CX3CR1+Ly6C− monocytic precursor generation and pulmonary CD11b+ DC accumulation, together with reduced Th2 inflammation ...

High‐Efficiency Precipitate Recycling Strategy Paves the Way for Efficient Sb2S3 Solar Cells Fabricated by CBD Method

open access: yesAdvanced Science, EarlyView.
A novel PR strategy was proposed to improve CBD‐derived Sb2S3 film quality. It synergistically optimized the CBO of CdS/Sb2S3 interface and the back‐contact barrier, while the VS2 donor defect was converted into SSb2 acceptor defect with lower concentration.
