A silicon nanoporous pillar array (Si-NPA) is a silicon hierarchical structure with regularly patterned surface morphology. An array of bundled ZnO nanorods was grown based on Si-NPA by a catalyst-free thermal evaporation method. The morphology of ZnO/Si-NPA was found to be greatly affected by the growth parameters su…
(Bi2O3Fe2O3)0.8(Nb2O5)0.2 was synthesized by solid state reaction method. (Bi2O3Fe2O3)0.8(Nb2O5)0.2 was made for the investigation of X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Dielectric property. XRD pattern reveals that three phases were obtained with Bismuth Iron Niobium Oxide. SEM elicits tha…
The development of lightweight optical mirrors is necessary for the next generation of large, space-borne telescopes. There is increasing interest in replicated polymer-based composite mirrors due to significant reductions in areal density and cost over conventional polished glass mirrors. However, space telescopes ha…
This research study is mainly targeted on fabrication and characterization of antibacterial poly(e-caprolactone) (PCL) based fibrous membrane containing silver chloride particles.

Semiorganic single crystals of L-proline potassium chloride (LPPC) were successfully grown from its aqueous solution by slow evaporation solution growth method at room temperature. The nucleation studies were carried out for the L-proline potassium chloride salt at room temperature. The critical nucleation parameters…
The carnivorous marine snail Pugilina cochlidium is found predominantly on the sea shores of the South-East Asia region. This sea creature lays a string of egg capsules up to a metre in length which houses its embryos. The egg capsule material must be able to withstand and resist the harsh and relentless tidal forces…
This article provides the studies of the kinetics of gel-formation of the polycaproamide-silica nanocomposite materials, obtained by the sol-gel method based on tetraethoxysilane, polycaproamide, hydrochloride-L-lysine and the alcohols. It is shown that a significant effect on the process of gel-formation, investigate…
