Nanocrystalline SnO2 core and ZnO as well as SiO2 shells coated core shell nanoparticles have been successfully synthesized by co-precipitation method. The as prepared samples were characterized by X-ray diffraction, FTIR, UV-Visible absorption, PL, FESEM, HRTEM with EDX measurements. The X-ray analysis showed that the obtained SnO2 core with tetragonal rutile crystalline structure and the shel...

Silver in its original form or in the form nanoparticles has been known from time immemorial in order to control different types of diseases. During last few decades, bacteria have made themselves resistant to varied antibiotics available in the market based on their genetic configurations. In our present study, simple and effective approach was performed to synthesize potent silver nanoparticl...

Matrix metalloproteinases (MMPs) have been studied extensively, and MMP inhibitors have been used as dental pretreatment agents prior to dentin bonding because they reduce collagen fiber degradation and improve bonding strength. However, morphologic characteristics of the collagen network after etching and of the post-adhesive dentin hybrid layers (DHL) after MMP inhibitors pretreatment have no...

Comparison between ZnO, InZnO, GaZnO and InGaZnO (IGZO) thin films prepared using spin coating method were studied in detail to find out contribution of In Ga towards changes the physical properties. From FESEM, ZnO has revealed an uneven non-uniform distribution grains on film. The addition caused be more separated inconsistent sizes. Ga, other hand transformed grain hexagonal shape surface wa...

a useful nanophotocatalyst (la,s-tio2) was prepared by a sol-gel method and characterized by uv–vis diffuse reflectance spectroscopy (drs), x-ray diffraction (xrd), photoluminescence emission spectroscopy (pl) and scanning electron microscopy (fesem). the results showed that the la,s-tio2, which calcined at 550 °c, contained only anatase phaseand its crystal size was 23 nm. in addition, the fes...

Using photo electrochemical etching technique (PEC), porous silicon (PS) layers were produced on n-type (Si) wafers to generate for with an orientation of (111) The results time investigated at: (5,10,15 min). X-ray diffraction experiments revealed differences between the surface sample sheet and synthesized silicon. largest crystal size is (30 nm) lowest (28.6 analysis Atomic Force Microscopy ...

The substrate's nature plays an important role in the characteristics of semiconductor films because thermal and lattice mismatching between film substrate. In this study, tin sulfide (SnS) nanostructured thin were grown on different substrates (polyester, glass, silicon) using a simple low-cost chemical bath deposition technique. structural, morphological, optical properties investigated X-ray...
