Laser-Induced Graphene for Electrochemical Sensing of Antioxidants in Biodiesel [PDF]

ACS Omega
Synthetic antioxidants are often introduced to biodiesel to increase its oxidative stability, and tert-butyl hydroquinone (TBHQ) has been selected due to its high efficiency for this purpose. The monitoring of antioxidants in biodiesel therefore provides information on the oxidative stability of biodiesels.

Tuning laser-induced band gaps in graphene [PDF]

Applied Physics Letters, 2011
Could a laser field lead to the much sought-after tunable band gaps in graphene? By using Floquet theory combined with Green's functions techniques, we predict that a laser field in the mid-infrared range can produce observable band gaps in the electronic structure of graphene. Furthermore, we show how they can be tuned by using the laser polarization.

Laser-induced Graphene in Polyimide for Antenna Applications

Crystals, 2023
Laser-induced graphene (LIG) has gained considerable attention recently due to its unique properties and potential applications. In this study, we investigate using LIG in polyimide (PI) as a material for antenna applications. The LIG-PI composite material was prepared by a facile picosecond laser (1064 nm) irradiation process, which resulted in a ...

Bioderived Laser-Induced Graphene for Sensors and Supercapacitors

ACS Applied Materials & Interfaces, 2023
The maskless and chemical-free conversion and patterning of synthetic polymer precursors into laser-inducedgraphene (LIG) via laser-induced pyrolysis is a relatively new but growing field. Bioderived precursors from lignocellulosic materials can also be converted to LIG, opening a path to sustainable and environmentally friendly applications.
