Biological membranes are highly dynamic (e.g., during cell division, organelle biosynthesis, vesicular transport, and neurotransmitter release). They can be shaped into protein-coated transport vesicles or tubules and undergo regulated fusion. The life of transport vesicles depends on highly specific and tightly regulated protein machineries, which not only shape the donor membrane into nascent...

Abstract Membrane separation technologies, with a broad application prospect in the field of hydrogen separation, are characterized by simplicity devices, high energy efficiency and environmental friendliness. The performance membranes is primary factor that determines separation. Therefore, development always research focus. This paper presents reviews developments features organic membranes, ...

Water recycling and the production of drinking water have recently become a very actual topic. Pressure membrane processes make it possible to produce with quality higher than or comparable product conventionally used such as sand filtration flotation. The operation technologies requires specialist knowledge. By correctly analysing input parameters controlling operating process, technology is c...

In recent decades, membrane-based processes have been extensively applied to a wide range of industrial processes, including gas separation, food industry, drug purification, and wastewater treatment. Membrane distillation is thermally driven separation process, in which only vapour molecules transfer through microporous hydrophobic membrane. At the operational level, performance membrane negat...
