Ultrasound-assisted handling force reduction during the solar silicon wafers production

Effects of vibration frequency and amplitude on friction reduction and wear characteristics of silicon

“…Only a limited number of studies could be found on the topic of friction reduction of silicon-based materials using vibration. The focus of these works was concerned with increasing the manufacturing process efficiency of these materials [18,19]. Since the frictional behavior under a given vibration condition is known to depend on the stiffness of the contact interface, the effect of vibration on friction is expected to depend on the type of material.…”

Ultrasound-assisted impurity removal from petroleum coke

“…The solar energy is one of the sustainable and clean energy sources [1][2][3]. Currently more than 80% of commercial solar cells are made of silicon, particularly multi-crystalline silicon [4][5][6]. The rapidly growing of worldwide solar cells market requires a large quantity of silicon feedstock [7][8][9][10].…”
