DOI: 10.1021/acsomega.5c04272
Abstract: Porous polyimide (PPI) is a key material for the oil supply parts in the bearing units of the momentum wheels and reaction wheels. The permeability of PPI determines the oil supply rate in the bearing… read more here.

DOI: 10.3390/en12010117
Abstract: Permeability is one of the key factors involved in the optimization of oil and gas production in fractured porous media. Understanding the loss in permeability influenced by the fracture system due to the increasing effective… read more here.
