The second international workshop on
Static-Tribo-Electricity of Powder

4th-6th August, 2016
Université de Technologie de Compiègne, Compiègne, France

an autumn of Compiene castle

After the success of STEP-1 (2014 Dec., Tokyo JAPAN), STEP-2 is going to Compiègne, France. STEP is a small intensive and intimate, discussion based, workshop on tribo-electricity and particle charging. The scope covers a range of fundamental and applicational aspects on the mechanism of generation of electrostatic charge, control of charged particles, measurement of electrostatic charge, and other topics related to tribo-electrisity. The workshop is open for all the researchers and engineers in the field of Physics, Chemistry, Chemical Engineering, Electric Engineering, Mechanical Engineering, and others. The workshop will contribute to provide opportunities to such contemporary researchers and engineers to have direct discussions on face to face, and to establish an international network.
