The infrared absorption spectrum from 3200 cm⁻¹ to 4025
cm⁻¹ of thin crystals of ⁶LiOH (99%⁶Li.) is presented and compared
to the spectrum of [superscript]NLiOH (93%⁷Li). A shift in only one of the band
pairs supports the lattice combinations model and assists in making
assignments for the major features of...
A configuration-interaction determination of wave
functions has been made for the ²S and ²P states of lithium,
and for the ¹S and ³S states of the lithium ion.
Two 1s, one 2s, one 3s, and two 2p functions served as
starting functions for all four states. Results of the
total...
Lithia-silica compositions between lithium disilicate and pure
silica were explored theoretically and experimentally, with special
emphasis on structural miscibility. Diffusion couples of vitreous
materials were prepared and annealed. Best success in preparation
was achieved by using electron-bombardment heating in vacuum to
melt the less refractory glass and let it solidify...
The interactions of chemical species with a solid surface play a role in many everyday applications such as heterogeneous catalysis, corrosion, and degradation reactions. Understanding the reaction kinetics and thermodynamics via rate constants and equilibrium constants, which require knowledge of the adsorbed species’ entropy, is essential for tuning these surface...
Recent studies of flow boiling within microchannels have shown high heat fluxes, leading to successful design and testing of compact heat exchangers, cooling systems for electronics and other high efficiency, miniature components. An experimental study of flow boiling of a concentrated salt solution in microchannels is presented. Experiments examined flow...
