Using first-principles method, surface energies of crystal planes of different tantalum carbide phases have been calculated. Quantum size effects are shown to possibly play a considerable role in determining accurate surface energies of these metalli

The microstructures and mechanical properties of tantalum carbides containing predominantly the ζ-Ta4C3−x phase are compared with the properties of the monocarbide (γ-TaC) and the hemicarbide (α-Ta2C) and two-phase composites. It is shown that a

Tantalum carbides are commonly processed by hot pressing, canned hot-isostatic-pressing, or spark plasma sintering because of their high melting temperatures and low diffusivities. This paper reports processing of dense ζ-Ta4C3−x by reaction sinte

Silver-doped hydroxyapatite nanopowders were prepared using a solution based sol-gel method and thoroughly characterized using x-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS). Antibacterial tests

Here we report the controlled synthesis of hydroxyapatite (HAP) HAP/Ti–alloy composite thin films using pulsed laser deposition (PLD) technique. A KrF excimer laser (wavelength 248 nm, 25 ns pulse duration, 2–3 J/cm 2 ) was used to grow thin film

Here we report the synthesis of high-quality single-phase thin films of BaZr0.8Y0.2O3−x (BZY20) by pulsed laser deposition (PLD) technique. BZY20 films were deposited on various substrates including single-crystal sapphire (0 0 0 1), LaAlO3 (0 0 1)
