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
Is Theosophy a Religion? theosophical journals often characterize an attempt to deal with errors as merciless "attacks on Christianity," "untheosophical assaults" and so on. She writes: Contrary to the allegations of Blavatsky which she made in her article, professor John Melton wrote that Theosophy is "established religious cult" along with christian science, rosicrucianism, spiritualism, satanism, mormonism, and so on. René Guénon called Blavatskian Theosophy "theosophism" and described it in his book as a "pseudo-religion." He believed that Blavatsky's "theosophism" is a "confused mixture" of Neoplatonism, Gnosticism, Jewish Kabbalah, Hermeticism, and occultism.
