Phase inversion (chemistry) 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 the characteristics of the resulting membrane are dependent on
Lines Composed in a Wood on a Windy Day Lines Composed in a Wood on a Windy Day "Lines Composed In A Wood On A Windy Day" is a poem by Anne Brontë. Brontë's love of the sea is expressed in this poem. In it, the sea is portrayed as "the great liberator". The line "the long withered grass in the sunshine is glancing" and the footnote she wrote at the bottom of the poem reveals that Brontë "loved wild weather, as she loved the sea, and hard country and snow". The poem further indicates the power and spiritual affect of the wind. The errors in punctuation on lines
