How do you mix solids uniformly?Informs about a technique for the analysis of slow granular mixing processes that are often encountered in industry, that is described by J. M. Ottino and co-workers at Northwestern University in `Nature 1995.'EBSCO_AspChemtech...
Consider a clear liquid that produces two gases that cannot be broken down into simpler substances when an electric current passes through it. Is this classified as an element, a compound, a heterogeneous mixture, or a homogeneous mixture...
It was known that Lichtenberg figures created within gases along dielectric surfaces become curved due to Lorentz force acting on the moving charged particles within the electrical discharges. The stronger the magnetic field, the greater the curvature: Since we could chill charged specimens to dry ...

that there are two basic differences between dusts and gases which are of substantially greater significance in design of safety standards than these similarities. Firstly, the physics of genera- tion and up-keeping of dust clouds and premixed gas/vapour clouds are substantially different. Secondly,...
