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 ...

Phosphorus Management on ‘Extensive' Organic Farms with Infertile Soils [PDF]

open access: yes, 2007
Two case-study farms with negative P balances maintained acceptable productivity without fertilisers, apparently by ‘mining’ ‘available’ P reserves in surface and subsoil.
