Phase inversion (chemistry) small pore membranes such as nanofiltration and reverse osmosis. Phase inversion (chemistry) Phase inversion is a chemical phenomenon exploited in the fabrication of artificial membranes. It is performed by removing the solvent from a liquid-polymer solution, leaving a porous, solid membrane. Phase inversion is a common method to form filtration membranes, which are typically formed using artificial polymers. The method of phase inversion is highly dependent on the type of polymer used and the solvent used to dissolve the polymer. Phase inversion can be carried out through one of four typical methods: The rate at which phase inversion occurs and
Lines Composed in a Wood on a Windy Day artistic style, but it may have done the opposite effect, as reflected in this poem. "Lines Composed in a Wood on a Windy Day" was written at Green Thorpe during Brontë's three-year stay from 1842-1845, and may have been influenced by homesickness. She wrote the poem on December 30, 1842. It was composed during the Victorian Crisis of Faith, a period which played a major role in poems and literature during its time. The meter may have been derived from Thomas Moore's style based on Irish folk song. His poem "I saw from the beach" has four quatrains similar in
