Microorganisms being eco-friendly and encompassing special features are widely employed in the biosynthesis of different metal nanoparticles (NPs). In the present study, the potential of different fungal strains has been explored for the synthesis of various morphologies of gold nanostructures. Preliminary confirmation of nanosized particles formation has(More)
Polyvinyl pyrrolidone capped Zn1-xMnxS (0 ≤ x ≤ 0.1) nanocrystals have been synthesized using wet chemical co-precipitation method. Crystallographic and morphological characterization of the synthesized materials have been done using X-ray diffraction and transmission electron microscope. Crystallographic studies show the zinc blende crystals having average(More)
In the present study, the adhesibility of Acanthamoeba castellani trophozoites and cysts to hydrogel contact lenses and to human cornea was investigated. Segments of unworn contact lenses were prepared (120 segments in total). In addition, 8 corneal buttons were obtained from 8 enucleated eyes. And each cornea cut into 8 radial segments. To these lens and(More)
The work in this paper addresses the capabilities and performance of single wall carbon nanotube (SWCNT) bundles as interconnects for applications in VLSI circuits. The carbon nanotube (CNT) bundles have potential to provide an alternate solution for the resistivity and electro-migration problems faced by traditional copper interconnect in very deep(More)
In the present work, polyvinyl pyrrolidone (PVP) capped Zn1-xSmxS (0.0001 ≤ x ≤ 0.1) nanoclusters were prepared using conventional chemical co-precipitation technique. The synthesized samples were characterized using X-ray powder diffraction (XRD), transmission electron microscope (TEM) and UV-Vis absorption studies. The XRD and TEM studies reveal that the(More)
In the present research paper carbon nanostructures viz. single walled carbon nanotubes, multi-walled carbon nanotubes, single walled carbon nanohorns and graphene nanoplatelets have been synthesized by CVD technique, hydrothermal method, DC arc discharge method in liquid nitrogen and microwave technique respectively. After synthesis 5 mm thick pallets of(More)
