Intrinsic Microporosity

To mitigate carbon emission from the combustion of fossil fuels, membrane is advantageous due to the fact that membrane is a thin interphase acting as a selective barrier separating two phases. This thinness, typically in the range of 100 nm to a few micrometers, provides an almost natural platform to implement functional nanostructures. In this review, the recent progress in nanostructured membrane materials for CO2 capture will be discussed, including applications in flue gas decarbonizing (CO2/N2 separation) and syngas purification (CO2/H2 separation). In addition, the fundamentals of membrane technologies are also introduced. The reviewed nanostructure formation is confined to solid state materials, including polymer with intrinsic microporosity, carbon-based membranes, zeolite, and metal organic framework.

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.
