Particulate Technology
Particulate systems impact a number of industries including advanced materials, environmental, chemical, mineral, energy, agricultural, pharmaceutical, and food processing. Particle technology deals with the characterization, modification, handling, production and utilization of a wide variety of particles, in both dry and wet conditions. Recently, these issues are being reinvestigated for the nano- and bio-technologies.
