Werndrup, Pia. 2005. Synthesis, Structure Determination, and Sol-Gel Processing of Heterometallic Heteroleptic Alkoxide Complexes of Late Transition Metals. Doctor’s dissertation. ISSN 1652-6880, ISBN 91-576-7026-9. The thesis describes synthesis of single-source precursors (SSP) for sol-gel preparation of thin films and nanocomposites. The structures of the SSPs were determined by singlecrysta...

Adoption of new management techniques that improve soil water storage and soil N plant availability yet limit N leaching may help improve environmental quality. A benchtop study was conducted to determine the influence of a single urea fertilizer rate (224 kg N ha) applied with band or fully mixed zeolite (clinoptilolite) application rates (up to 90 Mg ha) on NH4-N and NO3-N concentrations in a...

Recent developments of catalytic CVD generation of single-walled carbon nanotubes (SWNTs) by using alcohol as the carbon source are discussed. High-purity SWNTs can be generated at relatively low CVD temperatures from metal catalytic particles supported on zeolite [1, 2] (Fig. 1) or directly dispersed on flat substrates such as meso-porous silica [3], quartz and silicon [4, 5, 6]. Fig. 1 (a) is...

Zeolite 4A, synthetic silicate, has been shown to exhibit diverse biological activities such as anti-cancer and anti-oxidant activity. In the present study, we report that the zeolite 4A may improve skin-whitening. We found that zeolite 4A inhibited melanin production in a dose-dependent manner, which has not cytotoxicity. Zeolite 4A also inhibited alpha-melanocyte-stimulating hormone (alpha-MS...

Temperature-dependent zeolite synthesis has revealed a unique surface morphology, surface area and pore size which influence the immobilization of urease on gold electrode supports for biosensor fabrication. XRD characterization has identified zeolite X (Na) at all crystallization temperatures tested. However, N₂ adsorption and desorption results showed a pore size and pore volume of zeolite X ...

A novel confined-space synthesis method has been developed to synthesize zeolite nanocrystals. Colloidal silica nanoparticles serving as the silica source as well as the hard template were embedded in the mesoporous carbon via in situ polymerization of furfuryl alcohol (FA) in the presence of tri-block copolymer (Pluronic P123), and then reacted with an alkaline aqueous solution (Na2O-Al2O3-H2O...
