    New Generation Nanocrystalline Silicon Carbide for Implants and Prostheses

    By Nikesh A. Shah, Kacha Pinank, K. N. Rathod, Chirag Savaliya, Davit Dhruv, D. D. Pandya, J. H. Markna, N. A. Shah

    Abstract: Nanocrystalline silicon carbide (SiC) is an aspirant material for artificial heart valves primarily due to its low weight, high strength, acute hardness, wear resistance, inertness (SiC does not react with biological fluids), and deterioration resistance. Oxide ceramic materials such as alumina (Al2O3) and zirconia (ZrO2) are often used for medical applications like implants and prostheses because of their terrific biocompatibility and high wear resistance. Unfortunately, oxide ceramics cannot be used …

    Voltage-controlled TCR (Temperature Sensitivity) in Nanostructured Y0.95Ca0.05MnO3/Si, p-n Junction Diode

    By Davit Dhurv, J. H. Markna, P. S. Solanki, Nikesh A. Shah

    Abstract: The authors deposited a p-type Y0.95Ca0.05MnO3 on the n-type Si substrate using chemical solution deposition and form nanostructured Y0.95Ca0.05MnO3/n-Si, p-n junction diode with typical thickness of about 100 nm with polycrystalline in nature. The diode exhibits rectifying properties over the temperature range of 100–300 K. Voltage-dependent temperature sensitivity of Y0.95Ca0.05MnO3/n-Si, p-n junction diode has been studied in current perpendicular to film plane (CPP) geometry. The maximum percentage of TCR values …
