Zirconium diboride (ZrB2) films have been deposited by direct current magnetron sputtering (DCMS) from a ZrB2 compound target on Al2O3 (0001) substrates held at 600, 700, 800, and 900 °C, with two different axial magnetic field strengths, 34 104 G, generated using coil surrounding the substrate. Plasma probe measurements show an increase of ion fluxes floating-potential configurations factor 2....

Super steel materials play a vital role in the construction and fabrication of structural, piping and pipeline components. In assuring the integrity of onshore and offshore operating systems, they enable life cycle costs to be minimized. In this context, Duplex stainless steel (DSS) material related welding on constructions and fabrications plays a significant role in maintaining and assuring i...

The composition of polycrystalline hafnium oxide thin films has been measured by heavy-ion elastic recoil detection analysis (HI-ERDA). The films were deposited by high-pressure reactive sputtering (HPRS) with oxygen plasma at pressures between 0.8 and 1.6 mbar and during deposition times between 0.5 and 3.0 hours. Hydrogen was found to be the main impurity and its concentration increased with ...

Amorphous silicon oxynitride (SiOxNy) thin films were grown by reactive high power impulse magnetron sputtering from a pure silicon target in Ar/N2O plasmas. The elemental composition of the films was shown to depend on the target surface conditions during the film deposition, as well as on the reactive gas flow rate. When the target was sputtered under poisoned surface conditions, the film com...

Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder caused by an expanded (CAG)n repeat on the huntingtin gene. It is characterised by motor, psychiatric and cognitive disturbances. Diagnosis can be confirmed by direct genetic testing, which is highly sensitive and specific and is now considered definitive. This study focused on 21 patients presenting with a clinical p...

Electrolysis in Pd-LiOD(H), NaOD(H) and KOD(H) systems was carried out to clarify the specific role of the lithium for tremendously high density and the dynamic movement of the deuterium on the surface of the Pd cathode. Only for LiOD system with pulse mode current electrolysis, anomalous high density of deuterium and lithium and the dynamic movement of deuterium are observed on the surface of ...

Carbonaceous residues were formed hy irradiation of thin layers of frozen methane at 10 to 15 K by 17 MeV protons and ‘Fle“ ions and successive warming to ambient temperature. Analysis was performed by optical microscopy, scanning electron microscopy (SEM). Rutherford backscattering spectroscopy (RBS), elastic recoil detection analysis (ERDA). infrared spectroscopy (IR) in transmission. hydroge...
