  • We face many challenges in the 21st century, such as sustainably meeting the world’s growing demand for energy and consumer goods. I believe that new developments in science and technology will help solve many of these problems. Nanofabrication is one of the keys to the development of novel materials, devices and systems. Precise control of nanomaterials, nanostructures, nanodevices and their performances is essential for future innovations in technology.

  • Na+-Montmorillonite (Na+-MMT) minerals were organically modified by adding different amounts of surfactant octadecylamine corresponding to the cation exchange capacity (CEC) of the pristine montmorillonites. The characteristic of the organo-MMT were obtained by X-ray diffraction, FT-IR spectroscopy. The amount of added surfactant has direct effect on the interlayer separation and the organophicility-hydrophicility balance of MMT. An optimal surfactant/CEC ratio about 1.0 leads to two distinct distance of 15.5 Å and 32.

  • Epithelial cells cover the body (e.g. skin), cavities (e.g. stomach, uterus, bladder) and ducts (e.g. renal tubules, intestine) of multicellular organisms, and thus constitute the frontier between the individual and the external milieu. In areas that withstand strong mechanical or chemical stress (e.g. skin, esophagus, cornea, vagina) epithelia are stratified, whereas in the rest of the body, the epithelia independently of their morphology (e.g. columnar of the intestine, tubular of renal tubules, squamous of the lung), are organized in monolayers (Fig 1A).
