Hydrophilic PES Membranes: Enhanced Filtration Performance Polysulfone membranes offer a notable boost in purification efficiency when modified to be water-loving . Conventional polyethersulfone materials are usually water-averse, leading to fouling and reduced flux . Exterior treatment with water-attracting moieties improves contact and reduces b

Loss circulation during drilling operations presents a significant challenge to the success of any well. It results from drilling fluid being lost into the formation, leading to decreased wellbore stability. This condition can lead to stuck pipe and substantial economic losses. To minimize the risk of loss circulation, various strategies can be. Th
