Analysis of Permeance vs. Support Porosity for Thin Film Composite Membranes

Karampelas I.H., Zhu L., Jia W., Yavari M., Lin H., Furlani E.P., University at Buffalo (SUNY), US

Membranes are an important technology for industrial gas separation and seawater desalination and emerging applications such as CO2 capture. The key to the steady growth of membrane applications is high performance thin film composite (TFC) [...]

Designing Ultrathin Film Composite Membranes: Importance of a Gutter Layer

Ponnuru K., Kattula M., Karampelas I., Wang T., Zhu L., Jia W., Lin H., Furlani E.P., SUNY-Buffalo, US

Membrane technology has been widely adopted for water purification and gas separation. Industrial membranes are often thin film composites comprised of a thin, dense skin layer (100 nm or below) performing molecular separation and a [...]

Synthesis and Characterization of Nanocrystalline Eu3+-doped Gd2O3

Jáuregui-Rosas S., Tomar M., Jia W., Vásquez O., Fachini E., University of Puerto Rico, Mayaguez Campus, PR

Nanocrystalline Gd2-xEuxO3 phosphors by a simple sol-gel method have been synthesized. The effects of the annealing temperature and atomic fraction of Eu3+ ions (x) on the structural and luminescence properties of the mixed oxides have [...]

Biosensor for heavy metals using hydrothermally grown ZnO nanorod/nanotube and metal-binding peptides

Jia W., Reitz E.T., Lei Y., University of Connecticut, US

Certain heavy metals can pose potential health risks when consumed by humans due to their high toxicity. Specifically, the heavy metals mercury, lead and cadmium can be released into the environment through industrial use and [...]

Low-Temperature Synthesis and Magnetic Characterization of Doped-ZnS Nanostructures

Dussan Devia S., Tomar M.S., Morales L.M., Mata O., Jia W., University of Puerto Rico, Mayaguez Campus, PR

Nanostructured DMSs are of great importance due to potential applications in spintronics and photo-electronic devices. Recent studies propose that ZnS doped with transition metal ions can exhibit ferromagnetic behavior at room temperature. The present work [...]

YAG:Ce3+ Nanophosphor Synthesized with Salted Sol-Gel Method

Jia D., Jia W., Shaffer C.V., Weyant J.E., Goonewardene A., Guo X., Guo X.Z., Wang Y., Guo X., Guo X.Z., Li K.K., Zou Y.K., Jia D., Jia W., Boston Applied Technologies, Inc., US

Nanophosphors of Y3Al5O12:Ce3+ (YAG:Ce) were synthesized with a salted sol-gel (SSG) method, in which water-Heptane solutions of certain inorganic salts were used along with traditional metal alkoxides precursors. YAG phase could be formed at a [...]
