The 4-th international workshop on
Static-Tribo-Electricity of Powder

13-16, July, 2018
Lanzhou University, Lanzhou, China

STEP is a discussion-based international workshop on tribo-electricity and particle charging. The workshop scope covers a range of fundamental and applied topics related, but not limited to, 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 to all researchers and engineers in the field of Physics, Chemistry, Chemical Engineering, Electrical Engineering, Mechanical Engineering, and others. The STEP workshop provides an international forum to enable researchers and engineers in the field of tribo-electricity to have interactive dialog and to establish an international network.

Lanzhou city is located in almost center of mainland China, along the Yellow River. In the past the city was an important link on the ancient Northern Silk Road.
