Measurement of the spin diffusion rate of dipolar order in single crystal calcium fluoride
… known as dipolar order, in a single crystal of calcium fluoride. The experimental results for the component of the spin diffusion rate parallel with the azimuthal axis are ... for the [001] direction and ... for the [111] direction. These rates are significantly faster than those for Zeeman …

The Release of Calcium, Fluoride, and Phosphate Ions from Ion Permeable Microcapsules in a Rosin Varnish
… incorporated into several types of dentrifices. Calcium, fluoride, and phosphate salts already solvated were encapsulated and loaded into a rosin varnish. This approach was unique because it had the potential for providing bioavailable ions for remineralization. By altering certain variables, it …

The dissolution of lime in iron silicate melts.
… fayalite produced two reaction products, solid dicalcium silicate and a liquid rich in iron oxide. As dissolution proceeded, the precipitated particles of 2CaO.SiO[2] sintered together to form a tenacious layer between the two reactants. The rate of dissolution was calculated from the volume loss …

The effect of various slag constituents on the distribution of phosphorus between slag and metal
… for the phosphorus determination. The effects of calcium oxide, barium oxide, calcium fluoride, and magnesium oxide were investigated. For similar basicity ratios barium oxide was found to be a better dephosphorizing agent than any of the other constituents tested. Calcium fluoride's effectiveness …

Identifying interface-dominated behavior and cell configuration effects on the electrochemistry of calcium foil anodes
… research and practical assembly of rechargeable calcium (Ca)-based batteries will benefit from the ability to use Ca metal anodes to provide a sufficient Ca²⁺ reservoir for full cell electrochemistry. When Ca metal comes in contact with an organic electrolyte, a native solid electrolyte …

Optical pyrometry for noncontact temperature measurement
… laboratory and in the field. The design uses a calcium fluoride (CaF₂) rod which transports optical energy radiated from the molten particle to a beam splitter, where it is split into two signals. Each signal is filtered and focused onto an indium antimonide (InSb) photodetector which is liquid …

Fundamental studies on ionomer glasses
… followed by a two stage crystallization of calcium fluoride (fluorite) and anorthite. The anorthite phase crystallized from fluorite nuclei and, in effect, crystallization occurred by a bulk nucleation mechanism. The glass will also undergo significant crystallization to fluorite below the …

Quantum spin transport in paramagnetic systems
… dipolar coupled nuclear spins of the insulator calcium fluoride, under conditions where it was appropriate to neglect the coupling to any heat reservoir. The dynamics under these conditions is coherent and reversible, yet signatures of irreversibility (i.e. diffusion) are typically observed. …

Bioactive capabilities explored in polyurethane microcapsules and the inclusion into dental sealants and cement pastes
… cement and pit and fissure sealant with fluoride by toothbrushing, demonstrate the slow, sustained release of calcium, fluoride and phosphate ions from these materials initially formulated with remineralizing agents, examine the effect of microcapsules on cement adhesion to enamel and …

Diagnostic Neuropathology of Brain Tumours using Biophotonics and Spectrometry
… SVGP12 and 1321N1 were cultured and grown on calcium fluoride slides in triplicates. Spectra from each cell line was taken using both Raman and ATR-FTIR. The spectra was then analysed using multivariate statistics. In the elemental profiling study serum and tissue samples from 55 patients with …
