Something about Janus particles

The word Janus has its origin in the Roman god Janus. In Roman mythology this was the god of the gates, doors, doorways, beginning and endings; who is depicted with a double-faced head, each looking in opposite directions. Thus, in nature and materials science, asymmetric particles with two incompatible sides are called Janus particles. The…

Two-faced Janus Particles

A Janus particle is composed of two fused parts, two-faced, like the Roman god Janus of doorways who is usually depicted with his faces looking in opposite directions. These asymmetric particles have two distinctly different sides, i.e. each face made from a different surface chemistry, or substance, than the other one. This kind of particles…

Effect of Feed Frame Design and Operating Parameters On Powder Residence Time Distribution (RTD)

Powder compression in rotary tablet presses is used as a major step in the manufacture of pharmaceuticals, cosmetics, catalysts, personal care products, military ordnance, etc. In powder compaction applications, consistent flow of powders into the small die of a tablet press is key to producing tablets with consistent properties. Manufacturers often use mechanical devices, called…

X-Ray Photoelectron Spectroscopy Technique

X-ray photoelectron spectroscopy (XPS) is an analytical technique that studies the surface of structures, based upon the photoelectric effect. Each atom in the surface has core electron with the characteristic binding energy that is theoretically equal to the ionization energy of that electron. When an X-ray beam directs to the sample surface, the energy of…
