Laser‐Induced Coal‐Based Porous Graphene as Anode Toward Advanced Lithium‐Ion Battery

open access: yesAdvanced Science, EarlyView.
A one‐step laser‐induced strategy is reported to prepare porous graphene by utilizing bituminous coal as a precursor (LIG‐B). Laser irradiation transforms coal into graphene, with small molecules from the polymer separating, recombining in gas and forming 3D porous graphene upon quick gas release.

Understanding PFOS Adsorption on a Pt Electrode for Electrochemical Sensing Applications

open access: yesChemElectroChem, Volume 10, Issue 2, January 17, 2023., 2023
Electrochemical Detection of Per‐Fluoro Octane Sulfonate: The adsorption dynamic of PFOS molecule on a metal electrode depends on its concentration – at low concentration, random orientation of adsorption is observed; at medium concentration, PFOS molecule is aligned due to adsorbate‐adsorbate interaction. At high concentration, multiplayers of PFOS is
