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 ...

Development and evaluation of ion exchange hollow fibers [PDF]

open access: yes
An ion exchange hollow fiber impregnated with a vinylpyridine base was developed. The basic exchange resin used to impart the necessary permselectivity to the hollow fiber is a copolymer of vinylpyridine and dibromoethane prepared according to Rembaum. A

open access: yes, 2015
Water demineralisation is a process for the removal of mineral salts present in water, so the water produced has a high purity. Basically the process is like what is done in water softening through ion exchange process.

Studying Macromolecular Composition in Cell–Cell Interfaces Using 3D Membrane Reconstitution Systems

open access: yesAdvanced Science, EarlyView.
A comprehensive understanding of the interactions between proteins, lipids and glycocalyx components at the immune synapse is still lacking. Here, an artificial and a semi‐artificial model contact system were established to reconstitute the cell‐cell contact in 3D. The model systems enable the examination of macromolecule enrichment or depletion at the

Bioinspired Hierarchical Architecture with Water Transport Channels for Strong Adhesion at the Sweating Interface

open access: yesAdvanced Science, EarlyView.
To address adhesion failure in sweaty epidermal electronics, this study proposes a cross‐species, multi‐scale biomimetic interface. By modeling staged wet adhesion, it integrates self‐regulating liquid bridges with directional drainage. This design ensures stable, high‐performance flexible sensing in complex physiological environments, offering a ...
