Cysteic acid functionalized mineral oxide nanoparticles can be used to impart superhydrophilic performance on a range of woven and non-woven fabrics. Woven fabrics spray dip coated alumina iron based cysteic nanoparticles, were characterized by SEM, EDX the change in water contact angle was measured or where increased hydrophilicity sufficiently great that time for adsorption droplet measured. ...

A novel Ag-alumina hybrid SERS platform has been designed for the spectroscopic detection of surface reactions in steady state. Single crystalline and faceted silver (Ag) nanoparticles with strong light scattering were prepared in large quantity, which enables their reproducible self-assembly into large scale monolayers of Raman sensor arrays by Langmuir-Blodgett technique. The close packed sen...

The phytotoxicity of alumina nanoparticles loaded with and without phenanthrene (Phen) was investigated by means of root elongation (RE) experiments in this study. Five plant species, Zea mays (corn), Cucumis sativus (cucumber), Glycine max (soybean), Brassica oleracea (cabbage), and Daucus carota (carrot) were used in our study of phytotoxicity by root elongation experiments. The surface chara...

Ultrahigh performance cooling is one of the important needs of many industries. However, low thermal conductivity is a primary limitation in developing energy-efficient heat transfer fluids that are required for cooling purposes. Nanofluids are engineered by suspending nanoparticles with average sizes below 100 nm in heat transfer fluids such as water, oil, diesel, ethylene glycol, etc. Innovat...

We explored mechanisms for increasing U(VI) sorption by pretreating alumina surfaces with arsenate, which has a high affinity for binding with uranyl and is an analog for phosphate. Batch experiments were conducted at pH approximately 4 by pretreating a gamma-alumina surface with arsenate, followed by the addition of uranyl. Parallel experiments were conducted with different alumina loadings as...

Group VIII B metal oxides supported on gamma-alumina were investigated as catalysts and promoters of MoO3 hydrodesulfurization catalysis. Superior promotion was observed in PbO promoted catalyst compared to that of CoO, the typically accepted promoter. Other metal oxides, SnO and Ho2O3 exhibited reasonable hydrodesulfurization catalysis promotion but lower than for CoO promoted catalyst.

Polycrystalline Fe-doped alumina (Al2O3) ceramics have been produced and used as a substrate for organized carbon nanotubes (CNTs) growth by catalytic chemical vapor deposition (CCVD). In these substrates, Fe cations, which are the catalyst source, are initially substituted to Al in a-Al2O3, instead of being simply deposited as a thin Fe layer on the surface of the substrate. The selective redu...
