In this work, TiO2 films produced by rf sputtering of a TiO2 target, in argon and argon-oxygen plasmas were studied. The oxygen content in the feed gas was varied in a range of 3% – 20%. The chemical composition and structure of films were characterized by Rutherford backscattering spectrometry (RBS), X-ray photoelectron spectroscopy (XPS) and X-ray diffraction. Important information about the ...

The self-assembled (SA) films of imidazole and its derivatives were prepared on the iron surface. The protection abilities of these films against iron corrosion in 0.5 M H2SO4 solution were investigated using electrochemical impedance spectroscopy (EIS) and polarization techniques. The results of EIS and polarization curves demonstrated that films of the imidazole and its derivatives were able ...

Two-dimensional covalent-organic frameworks (2D-COFs) on surfaces offer a facile route to new 2D materials. Schiff-base condensation reactions have proven to be an effective fabrication route for such materials. We present scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy (XPS) studies of porphyrin 2D-COFs grown at a solid-vapour interface. XPS shows that covalent links b...

In this paper, we describe work in progress on a methodology for the hardware-software codesign of the Xilinx Micro-Kernel (XMK), leveraging the Xilinx Platform Studio (XPS) [1]. Combined with the Microblaze [2] softprocessor and the XPS system design framework, XMK is an ideal target for hardware acceleration due its modular design and configurability. Our methodology will target FPGA devices ...

Anatase N-doped TiO2 nanoparticles were synthesized using ultrasound at low frequency and room temperature. The samples characterized by techniques including XRD, TEM, HRTEM, FT-IR, XPS, and UV–Vis spectroscopy. XPS indicated the existence of nitrogen as an anion dopant within the TiO2 lattice. The solar photocatalytic activity of N-doped TiO2 studied for th...
