Abstract Soft magnetic materials with stable permeability up to hundreds of megahertz (MHz) are urgently needed for integrated transformers and inductors, which are crucial in the more-than-Moore era.However, traditional frequency-stable soft magnetic ferrites suffer from low saturation magnetization and temperature instability, making them unsuita

A simple approach to test photocatalyst activity has been described.Photocatalytic degradation of a model dye was measured using a smartphone.The color changes were registered directly in the micro-photoreactor.The model dye Rhodamine B was degraded under UV irradiation (365 nm).The effect of H2O2 concentration and titanium dioxide photocatalyst do
