Silicon Nanocluster in Silicon Dioxide: Cathodoluminescence, Energy Dispersive X-Ray Analysis and Infrared Spectroscopy Studies

High Biological performance of Silicon Substituted Nano Hydroxyapatite Synthesized in Simulated Body Fluid at 37°C

In this work, we report high biological performance of silicon substituted nano hydroxyapatite (nHA) prepared by immersion of calcium phosphate and sodium silicate as precursors in Simulated Body Fluid (SBF) solution for 24, 36, 48 and 72 hrs at 37°C. Characterization and chemical analysis of the synthesized powders were performed by Fourier transform, infrared spectroscopy (FT-IR), X-ray powde...

Characterization of silicon dioxide films on 4H-SiC Si (0001) face by cathodoluminescence spectroscopy and x-ray photoelectron spectroscopy

Macroporous silicon membranes as electron and x-ray transmissive windows

Macroporous silicon membranes are fabricated whose pores are terminated with 60 nm thin silicon dioxide shells. The transmission of electrons with energies of 5 kV–25 kV through these membranes was investigated reaching a maximum of 22% for 25 kV. Furthermore, the transmission of electromagnetic radiation ranging from the far-infrared to the x-ray region was determined. The results suggest the ...

Growth of Zinc Oxide Nanowires on Silicon (100)

Single crystalline zinc oxide (ZnO) nanowires have been grown on Si (100) substrates by a vapor-liquid-solid (VLS) process at temperatures in the range 850-950 °C in an inert atmosphere. The VLS-grown ZnO nanowires have been characterized in detail using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), X-ray photoelectron spectroscopy (XPS), transmission electron mi...
