Highly Efficient Inorganic-Coated FeSiAl/Biotite Soft Magnetic Composites

open access: yesJournal of Materials Research and Technology, 2022
FeSiAl/biotite soft magnetic composites were synthesized by mixing atomized FeSiAl and biotite at a specific mass ratio via ball milling. The structures, morphologies, elemental distributions, and magnetic properties of the FeSiAl/biotite composites were

Potassium at the Origins of Life: Did Biology Emerge from Biotite in Micaceous Clay?

open access: yesLife, 2022
Intracellular potassium concentrations, [K+], are high in all types of living cells, but the origins of this K+ are unknown. The simplest hypothesis is that life emerged in an environment that was high in K+.
