Hydrophilic PES Membranes: Enhanced Filtration Performance Polysulfone filters offer a significant enhancement in separation efficiency when modified to be water-attracting. Conventional polysulfone substances are generally water-averse, leading to blocking and diminished flow rate . Outer modifica

Drilling operations often present numerous challenges for engineers. One of the most pressing concerns is loss circulation, a situation where drilling fluid escapes into the formation, leading to various detrimental effects. This phenomenon can cause wellbore instability, tool damage, and ultimately
