We report in this study the mechanical, structural and compositional characteristics of amorphous carbon nitride films (aCNx) deposited on Si(100) using RF magnetron sputtering of graphite targets in pure nitrogen and under different RF powers. The properties of the films were determined in their as deposited state using nuclear reaction analysis (NRA), elastic recoil detection (ERDA), infrared...

Abstract The reduction of N p O P and P u O p by oxalate, citrate, and ethylenediaminetetraacetic acid OST1 (EDTA) was investigated in low ionic strength media and brines. This was done to help establish the stability of the An(VI) oxidation state in the presence of organic complexants. The stability of the An(VI> oxidation state depended on the pH and relative strength of the various oxidation...

Within this work the effect of B content on microstructure, phase composition and mechanical properties CVD Ti(B,N) coatings is investigated. with contents from 0 (fcc-TiN) to ∼5, ∼15, ∼30, ∼45 66 (h-TiB2) at.% have been deposited by CVD. The elemental was confirmed ERDA their microstructure investigated using XRD SEM. With increasing content, a transition fcc h-dominated structure via dual-pha...

Electromorphic variation among populations of Drosophila mojavensis, D. arizonensis and D. longicornis was examined for seven genetic loci. The average electrophoretic mobility for a population was used as the metric. D. mojauensis and D. arizonensis use larval substrates in different parts of their geographic ranges, while D. Zongicornis is more narrowly restricted to different species of the ...

Thin films of hafnium oxide have been grown by high pressure reactive sputtering on transparent quartz substrates (UV-grade silica) and silicon wafers. Deposition conditions were adjusted to obtain polycrystalline as well as amorphous films. Optical properties of the films deposited on the silica substrates were investigated by transmittance and reflectance spectroscopy in the ultraviolet, visi...

[1] We present two continuous global geomagnetic field models for recent millennia: CALS3K.2, covering the past 3000 years, and CALS7K.2, covering 7000 years from 5000 BC to 1950 AD. The models were determined by regularized least squares inversion of archeomagnetic and paleomagnetic data using spherical harmonics in space and cubic B splines in time. They are derived from a greatly increased n...

Nanocomposite Ti/hydrocarbon plasma polymer (Ti/ppCH) films were deposited by DC magnetron sputtering of titanium target in n-hexane, argon, or a mixture of these two gases. The resultant films were heterogeneous, with inorganic regions of nanometer scale distributed within a plasma polymer matrix. The titanium content was controlled by adjusting the argon/n-hexane ratio in the working gas. In ...
