Low-cost electron detector for scanning electron microscope

Electron microscopy is an indispensable tool for the characterization of (nano) materials.Electron microscopes are typically very expensive and their internal operation is often shielded from the user.This situation can provide fast and high quality results for researchers focusing on e.g.materials science if they have access to the relevant instru

Simplified Grinding Temperature Model Study

A study of a simplified mathematical model for determining the grinding temperature is performed.According to the obtained results, the equations of this model differ slightly from the corresponding more exact solution of the one-dimensional differential equation of heat conduction under the boundary conditions of the second kind.The model under st
