Abiogenesis - Wikipedia

2019-1-24Abiogenesis, or informally the origin of life, is the natural process by which life has arisen from non-living matter, such as simple organic compounds. While the details of this process are still unknown, the prevailing scientific hypothesis is that the transition from non-living to living entities was not a single event, but a gradual process of increasing complexity that involved molecular

Filtration - GVS Filter Technology

Hydrophilic – Hydrophobic Membranes. Hydrophilic membranes have permeability of aqueous solutions and once wetted, they stop gasses. This means that aqueous solutions pass through hydrophilic membranes but gas is stopped when the membrane is wet until the applied pressure exceeds the "bubble point", at which time the air will evacuate the pore, the liquid is expelled, and the gas will go
