What's the difference between trioxide and yttria?
Trioxide
Definition:
(n.) An oxide containing three atoms of oxygen; as, sulphur trioxide, SO3; -- formerly called tritoxide.
Example Sentences:
(1) Each group was further divided into two groups; one was given the diet containing 100ppm of arsenic trioxide and the other a diet containing "arsenic compound" (100ppm as arsenic trioxide).
(2) The methods used included gel filtration procedures, methylation analysis, periodate oxidation, Smith degradation, oxidation with chromium trioxide and enzymic degradations of the isolated oligosaccharide.
(3) Genotoxic evaluations of arsenic trioxide, dieldrin, lead tetraacetate and their nine binary and one tertiary mixtures were performed using the Tradescantia micronucleus (Trad-MN) assay.
(4) IXb, diacetate of IX, unpurified, was converted to IXf with chromium trioxide in glacial acetic acid.
(5) The human epidemiological studies have provided convincing evidence that zinc chromate is a potent carcinogen and there is some evidence that calcium chromate and chromium trioxide also constitute a cancer hazard in humans.
(6) The single oral dose of arsenic trioxide was further followed by excretion of an amount of arsenic equivalent to about 60% of the administered dose: 49% in the urine and 11% in the feces.
(7) The sulfur trioxide radical anion also reacts directly with BP-7,8-diol to form a sulfonate adduct.
(8) Sulfuric acid aerosol is produced by combining sulfur trioxide (SO3)(g) vapor with water vapor in the exposure chamber air supply.
(9) The structure of the poly(glycosyl)peptides was studied using methylation analysis, exoglycosidase treatments, acid hydrolysis of the native as well as the N-deacetylated glycopeptides, and chromium trioxide oxidation.
(10) Separation, final concentration and refining of by-product arsenic as the trioxide is achieved at smelters.
(11) The chemicals studied were: bleomycin, t-butyl hydroperoxide, chromium trioxide, cumene hydroperoxide, formaldehyde, glyoxal, glutaraldehyde, hydrogen peroxide, paraquat, and phenylhydrazine.
(12) To explore the role of arsenic as a human carcinogen, the respiratory cancer mortality experience (1938 to 1977) of 8,045 while male smelter employees in Montana was examined relative to cumulative exposure to arsenic trioxide and was compared with that of the white male population of the same region.
(13) The studies involved the use of methylation analysis, partial hydrolysis with 48% hydrogen fluoride, Smith degradation, oxidation with chromium trioxide, and comprehensive proton and carbon-13 nuclear magnetic resonance studies, in which one- and two-dimensional experiments were carried out.
(14) Treatment of 11 and 20 with sulfur trioxide-pyridine afforded the sulfoamino derivatives, deacetylation of which gave sugar analogs of cyclamate-like compounds.
(15) The relationship between airborne concentrations of arsenic and the urinary excretion of inorganic arsenic metabolites (inorganic arsenic + methylarsonic acid + dimethylarsinic acid) have been studied among smelter workers exposed to arsenic trioxide.
(16) The decalcification consists of 5% HNO3, absolute alcohol and 0,5 chromic trioxide.
(17) Intake and excretion of arsenic from Hizikia-diet reached a steady state within 4 days of administration as was the case of arsenic trioxide.
(18) However, the additional possibility of oxidation of As(III) to As(V) in vivo under extreme immediate postingestion conditions is suggested by initial high urinary As(V) after arsenic trioxide intoxication.
(19) This paper describes their influence in vivo in some preliminary tests and in vitro for iron trioxide only.
(20) It was shown that a single dose of arsenic trioxide administered to hamsters was chiefly methylated in vivo into methylarsonic acid (MAA) and dimethylarsinic acid (DMAA), and that inorganic arsenic accounted for the major portion of total arsenic that deposited in organs and tissues, followed by MAA and DMAA in decreasing sequence of significance.
Yttria
Definition:
(n.) The oxide, Y2O3, or earth, of yttrium.
Example Sentences:
(1) This was accompanied by a strength decrement and it is concluded that these yttria-stabilized ZTA and TZP materials are unsuitable as implant materials.
(2) Composites containing ceria and magnesia as substitutes for yttria behave similarly.
(3) Thin films of the superconductive oxide YBa2Cu3O7-x have been made by electron-beam coevaporation of the metals in an oxygen atmosphere onto single-crystal [001]-oriented SrTiO3 and yttria-stabilized zirconia (YSZ) substrates.
