Sustainable Production of Biomass‐Derived Graphite and Graphene Conductive Inks from Biochar

open access: yesSmall, Volume 20, Issue 52, December 27, 2024.
High quality bio‐graphite is obtained by graphitization of sustainably sourced biomass, leading to crystal sizes that exceed that of spheroidized natural graphite. Life cycle analyses of pre‐carbonization and iron‐catalyzed graphitization steps highlight improvements in sustainability compared to incumbent routes to produce graphite.

The Magnetic Field from Cylindrical Arc Coils and Magnets: A Compendium with New Analytic Solutions for Radial Magnetization and Azimuthal Current

open access: yesAdvanced Physics Research, Volume 3, Issue 7, July 2024.
This study provides analytic solutions for the magnetic field of coils and magnets that have a non‐axisymmetric cylindrical geometry with a rectangular cross‐section. The equations can be readily applied to find the magnetostatic field in linear or non‐linear systems that contain a large set of elements.
