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 ...

Haiyang-2 (HY-2) missions have accumulated sea surface height (SSH) observations on a global scale for more than 10 years. Four satellites, HY-2A, HY-2B, HY-2C and HY-2D, provide even but differently distributed data, which play complementary role in marine gravity studies with other missions. Therefore, this paper evaluates the performances of HY-2 altimetric data modeling from following four ...

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...

This study examines the performance of a new adsorbent, hexagonal nanostructured zeolite particles (HNZP) for acetone adsorption and compares the results with that of commercial mobil synthetic zeolite-5 (ZSM-5) type zeolite. The HNZP is a pure siliceous adsorbent with different values of pore diameter and surface area being adjustable by the manufacturing condition. The results indicate that a...

the aim of this sutdy is to prepare histocompatability y(hy) antibody in female mouse at the first phase (current study), and to separate mouse embryos with regard to their sex, to be able to obtain offsprings of disired sex, by means of hy antibody, at the second phase. totally 421 balb/c inbred mice were used. antibodies were produced in females by intraperitonial injections of spleen and tes...

The operation of reforming catalysts in a fixed bed reactor undergoes high level interaction between the operating parameters and reaction mechanism. Understanding such an reduces catalyst deactivation rate. In present work, three kinds nanocatalysts (i.e., Pt/HY, Pt-Zn/HY, Pt-Rh/HY) were synthesized. catalysts’ performances evaluated for n-heptane reactions reactor. conditions applied followin...
