Single strand scission in duplex DNA is caused by hydroxylamine, Na-nitrite or oximes of glucose and galactose of proper low molarities. The suitable nicking in the DNA-molecule brings about the elevation of its template nature. Excessive breakage of DNA, however, reduces its template activity. The results have been discussed in relation to an effect causing cyto-differentiation and -anomalizat...

We investigated the effect of bias voltage and carrier gas on hydrogen sensing performance tungsten oxide nanobeads. The nanobeads were prepared by a template-assisted method followed calcination. porous single walled carbon nanotube thin film was used as sacrificed template for deposition tungsten, thermal calcination at high temperature to oxidize W into WO3 burn out template. crystal structu...

in our current study, supercritical water impregnation (scwi) was introduced as a unique catalyst preparation method by employing the high diffusivity property of supercritical water. the method allows nano-particles to place on support surfaces in extremely dispersed conditions. the silica-based nanocatalyst granules for this purpose were prepared by initial impregnation of highly porous silic...

cazro3 nanoceramics were successfully synthesized at 700 c using the molten salt method, and the effects of processing parameters, such as temperature, holding time, and amount of salt on the crystallization of cazro3 were investigated. cacl2, na2co3, and nano-zro2 were used as starting materials. on heating, cacl2–nacl molten eutectic salt provided a liquid medium for the reaction of caco3 an...

Two approaches for metal ion incorporation were employed to introduce Ca2+ into SBA-15; Direct Synthesis (DS) and Wet Impregnation (WI). The non-ionic template was removed by two different methods; calcination and solvent extraction. The obtained catalysts were characterized by means of X-Ray Powder Diffraction (XRD), Energy Dispersive X-ray (EDX), and FT-IR spectroscopy. The bas...
