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

Advanced 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 ...

Lithium recovery from desalination brines using specific ion-exchange resins

, 2019
This study evaluated the possibility of recovering lithium from brines by ion-exchange procedures. Three commercial ion-exchange resins were studied: K2629, TP207 and TP208. Different tests have been carried out with artificial solutions and real brines.

Pre-Reducing Process Kinetics to Recover Metals from Nickel Leach Waste Using Chelating Resins

International Journal of Chemical Engineering, 2018
The main problem of the separation process from nickel mining using the ion exchange technique is the presence of iron, which precipitates in pH above 2.00 and causes coprecipitation of copper and cobalt. Chelating resins have the main advantage of being

Synthesis of novel ion exchange/coordination resins and the mechanistic study of ion exchange/redox dual mechanism bifunctional polymers with their application in metal ion recovery

, 1989
Selective separation of metal ions is important for many purposes, including treatment of waste water and recovery of precious metals. Polymer supported ion exchange ligands have good kinetics but lack selectivity.
