	abstract = {A series of monolithic and multilayer coatings of chromium nitride with various compositions and architectures were deposited at low temperatures (< 200 degreesC) on silicon substrates using ion-assisted reactive magnetron sputtering. All coatings had a total thickness in the 1.5 +/- 0.3 mum range. The multilayer coatings were designed such that their period and CrN fraction varied in the range 30-150 nm and 0.50-0.93, respectively. Real-time in situ ellipsometry was used to monitor and control the deposition process. The deposited coatings were characterized post-deposition using X-ray diffraction (XRD): Rutherford backscattering (RBS), X-ray photoelectron spectroscopy (XPS), and spectroscopic ellipsometry (SE). The primary chromium nitride phases (Cr2N and CrN) in the films were identified using XRD. The chemical composition of selected samples was determined from RES and XPS measurements. The phase composition of the deposited layers was deduced from the analysis of the SE data. The mechanical properties of the coatings were evaluated using a nanoindenter. The measured hardness values were in excess of 20 GPa. The results of the different characterization and testing techniques were correlated and follow-up work on this project suggested.

	abstract = {The in vitro effects of four different species of arsenic (arsenate, arsenite, monomethylarsonic acid, and dimethylarsinic acid) in mobilizing iron from horse spleen ferritin under aerobic and anaerobic conditions were investigated. Dimethylarsinic acid (DMA((V))) and dimethylarsinous acid (DMA((III))) significantly released iron from horse spleen ferritin either with or without the presence of ascorbic acid, a strong synergistic agent. Ascorbic acid-mediated iron release was time-dependent as well as both (DMA((III))) and ferritin concentration-dependent. Iron release from ferritin by DMA((III)) alone or with ascorbic acid was not significantly inhibited by superoxide dismutase (150 or 300 units/ml). However, the iron release was greater under anaerobic conditions (nitrogen gas), which indicates direct chemical reduction of iron from ferritin by DMA((III)), with or without ascorbic acid. Both DMA((V)) and DMA((III)) released iron from both horse spleen and human liver ferritin. Further, the release of ferritin-iron by DMA((III)) with ascorbic acid catalyzed bleomycin-dependent degradation of calf thymus DNA. These results indicate that exogenous methylated arsenic species and endogenous ascorbic acid can cause (a) the release of iron from ferritin, (b) the iron-dependent formation of reactive oxygen species, and (c) DNA damage. This reactive oxygen species pathway could be a mechanism of action of arsenic carcinogenesis in man. (C) 2000 Academic Press.},
