This is the final technical report for the KISS Technical Development program entitled “Development of Ultrasensitive Photon Detectors and Microwave Amplifiers Using Superconducting Nitride Thin Films”. The Technical Development phase started in January 2011 and concluded in December 2012. The overall goal of this program was to explore the application of high-resistivity superconductors, parti...

Different oxidation states of titanium nitride thin films, including pure TiN(h 0 0), TiN1−xOx(h 0 0), Ti2O3(0 0 l) and pure anatase TiO2(0 0 l), were prepared by pulsed laser deposition with various oxygen pressures (PO2) using a TiN target. Elaborative evolutions of the crystal and electronic structures of the obtained films were examined systematically by x-ray diffraction and x-ray absorpti...

Platinized TiN is shown to be a very good catalyst for the electrochemical oxidation of methanol; it does not contain Ru and the CO poisoning effect is alleviated by the presence of TiN.

Standard nitride recipes for Savannah were tried first. Woollam M2000 spectroscopic ellipsometer (Woollam) and SSI SProbe X-Ray Photoemission Spectrometer (XPS) were used for thickness and composition measurements. However, the results were undesirable. For example, the results of Woollam showed that Hf3N4 films with 500, 375, and 250 cycles well matched to the corresponding HfO2 models. Furthe...

The interface formation between different thicknesses of strontium titanate (SrTiO3) or titanium nitride ~TiN! with a 2000 Å Fe3O4 film is studied using x-ray absorption spectroscopy ~XAS! and x-ray magnetic circular dichroism ~XMCD!. Our results show that the deposition of 10–50 Å of TiN results in an immediate and substantial removal of oxygen from the near interface region, resulting in the ...

Hip resurfacing is gaining popularity as an acceptable treatment option for young active patients with hip osteoarthritis. The Buechel-Pappas hip resurfacing system has a titanium alloy femoral and acetabular component with a polyethylene liner. The titanium nitride coating of the femoral component has been shown to have a very low wear rate during in vivo laboratory studies. Although it has be...

The aim of the present study was to evaluate cell adhesion and cell survival of mammalian retinal neurons on different materials used for the production of multi-photodiode arrays (MPDAs) intended for implantation in the subretinal space of patients suffering from progressive photoreceptor cell loss. The survival rates of different types of retinal neurons and glia cells were monitored by conve...

Recently, the defect-induced static magnetic behaviours of nanomaterials have been a cutting-edge issue in diluted magnetic semiconductor materials. However, the dynamic magnetic properties of nanomaterials are commonly ignored if their bulk counterparts are non-magnetic. In the present research, titanium nitride-carbon (TiN/C) nanocomposites were found to exhibit both static and dynamic magnet...

Metal–support interaction strongly influences the catalytic properties of metal-based catalysts. Here, titanium nitride (TiN) nanospheres are shown to be an outstanding support, for tuning electronic property platinum (Pt) nanoparticles and adjusting morphology indium sulfide (In2S3) active components, forming flower-like core–shell nanostructures (TiN-Pt@In2S3). The strong metal–support betwee...

Dense machinable α-SiAlON/BN composites were fabricated by hot-pressing using turbostratic boron nitride (tBN) obtained from nitridation of melamine diborate. The tBN was added to the starting powders, or introduced as a coating that formed in situ on α-Si3N4 carrier powders during nitridation, and was subsequently converted to hexagonal boron nitride (hBN) during hot pressing by solution repre...
