A Review on Recent Progress in Membrane Distillation Crystallization

Membrane distillation (MD) is an emerging membrane separation technique which provides a competition for the conventional separation process such as reverse osmosis (RO) and thermal distillation. The MD process was first developed in the 1960s, but only recently garnered the interest from academics and industry due to the advancement of membrane fabrication technique. The MD is a thermal-driven process which has an ability to be integrated with renewable energy and/or waste heat. The driving force of the MD process is vapor pressure difference where the feed vapor is transported through the non-wetted hydrophobic porous membrane to the permeate regime where permeate will be collected via condensation. As such, the MD possesses a theoretical rejection rate of nearly 100%. This review addressed the recent progress of the MD process in terms of membrane fabrication, integration with renewable energy and/or other membrane separation process as well as applications of MD in various industries. This paper may serve as an update of the recent progress of MD which in some way, is able to help the researchers explore the new investigation field in MD for it to be commercially more viable.

Ferroelectric Domains

Recent progress in the electron-mirror microscopy (EMM), e.g., an improvement of its resolving power together with an increase of the magnification makes it useful for investigating the ferroelectric domain physics. English has recently observed the domain texture in the surface layer of BaTiO3. The present authors ) have developed a theory by which one can evaluate small one-dimensional electric fields and/or topographic step heights in the crystal surfaces from their EMM pictures. This theory was applied to a quantitative study of the surface pattern of BaTiO3).

Complete Understanding

Recent progress in the application of scanning tunneling microscopy (STM) and tunneling spectroscopy (STS) to oxide surfaces has allowed issues of image formation mechanism and spatial resolution limitations to be addressed. As the STM analyses of oxide surfaces continues, it is becoming clear that the geometric and electronic structures of these surfaces are intrinsically complex. Since STM requires conductivity, the oxides in question are transition metal oxides that accommodate aliovalent dopants or nonstoichiometry to produce mobile carriers. To date, considerable effort has been directed toward probing the structures and reactivities of ZnO polar and nonpolar surfaces, TiO2 (110) and (001) surfaces and the SrTiO3 (001) surface, with a view towards integrating these results with the vast amount of previous surface analysis (LEED and photoemission) to build a more complete understanding of these surfaces. However, the spatial localization of the STM/STS provides a level of detail that leads to conclusions somewhat different from those made earlier.
