Electronic structure of stannous oxide
We present an ab initio study of the electronic structure of SnO. Density functional theory in the local density approximation (DFT-LDA) is used in conjunction with carefully tested smooth pseudopotentials. Total energies and charge densities are calculated and analysed as a function of the atomic geometry, with a particular emphasis on the importance of low-chargedensity contributions to the i...
متن کاملCardioversion and "false positive" technetium-99m stannous pyrophosphate myocardial scintigrams.
The present studies performed in experimental animals demonstrate that electrical direct current cardioversion can produce skeletal muscle damage and increased technetium-99m stannous pyrophosphate (99mTc-PYP) uptake; in experimental animals the electrically damaged skeletal muscle shows necrosis with extensive calcium deposition. In addition, the frequent administration of high energy cardiove...
متن کاملInhibition of enamel erosion by stannous fluoride containing rinsing solutions.
This in vitro study investigated the erosion-inhibiting properties of dental rinses during erosion in the presence of the salivary pellicle. The erosion inhibition by a Sn/F containing dental rinse (800 ppm Sn2+, 500 ppm F –, pH = 4.5) was compared with a fluoridated solution (500 ppm F –, pH = 4.5) and water(control). Calcium release and enamel softening were significantly reduced among enamel...
متن کاملClinical evaluation of stannous fluoride as an anticaries mouthrinse.
Two experienced clinical investigators examined all participating children initially and at the end of the first and second school years. The results from each examiner showed significant reductions in dental caries for the test group at all intervals. In the final results two examiners independently observed caries reductions of 33% and 43% in DMFS scores for the group using the stannous fluor...
متن کاملAerosol-assisted CVD of SnO from stannous alkoxide precursors.
The stannous alkoxides [Sn(OR)2] [R = i-Pr, t-Bu, C(Et)Me2, CHPh2, CPh3] have been synthesised by reaction of Sn(NR'2)2 with two equivalents of HOR [R' = Me, R = i-Pr; R' = SiMe3, R = t-Bu, C(Et)Me2, CHPh2, CPh3]. Single crystal X-ray diffraction analysis of the bis(diphenylmethoxide) (4) and bis(triphenylmethoxide) (5) species have shown them to comprise three-coordinate Sn(ii) centres through...
