Development of dense scintillating hard fluoride glasses for the electromagnetic caorimeter of the proposed compact muon solenoid
Hafnium based Heavy Metal Fluoride glasses have been produced and evaluated in a search for new dense scintillating materials. The principal motivation was the electromagnetic calorimeter of the Compact Muon Solenoid (CMS), a proposed detector for the Large Hadron Collider (LHC) at CERN, Geneva. …

Addition of carbonyl fluoride to organic and inorganic nitriles
Carbonyl fluoride will add to alkyl and perfluoroalkyl nitriles and alkane dinitriles in anhydrous acids to form the corresponding α,α-difluoroalkyl isocyanate, perfluoroalkyl isocyanate, or α,α,ω,ω-tetrafluoro- α,ω-diisocyanatoalkane. With acetonitrile the reaction proceeded slowly in anhydrous …

Synthesis and evaluation of rare-earth doped glasses and crystals for optical refrigeration
… laser-cooling efficiency in Yb3+ and Tm3+ doped fluorides. The first instance of laser-induced cooling in a Tm3+-doped crystal, BaY2F8 was reported. Cooling by 3 degrees Kelvin below ambient temperature was obtained in a single-pass pump geometry at λ = 1855 nm. Protocols were developed for …

Mechanistic Studies of Salt Effects on Bimolecular Electron-Transfer Reactions of Pentaamine Ruthenium Pyridyl Complexes Studied by 19F NMR Line-Broadening and T2 Spin-Echo Techniques
… earlier stopped-flow work, addition of alkali-metal fluoride salts increased the rate of ET between the like-charged redox reactants in good quantitative agreement with the quantitative predictions of the Debye-Huckle-Bronsted theory of ion atmosphere charge screening effects, but the other …

Electron Transfer and Other Reactions Using Atomic Metal Anions
The atomic metal anions Rb-, Cs-, Cu-, Ag- and Fe- have been generated in the gas phase and reacted with various neutral reactants in a triple quadrupole mass spectrometer. The metal anions were formed via electrospray ionization of the metal-oxalate solutions and form in gas phase between the …
