This electron microscope image shows spherical bismuth powder. Each particle in the photo is about the diameter of a human hair (approximately 60 micrometers). A newly developed process transforms ...

Spray drying is the name given to the rapid drying process of creating dry powders from liquid slurry. The liquid is typically sprayed with hot gas to accelerate the drying stage, which renders it ...

Raman spectra acquired from the surface of the metallic glass powder isothermally oxidized for systematically increasing duration of time at 580 °C for 120; 240; 360; 480; 600 and 720 min and at 650 ...
