Two types of instabilities were previously identified in inductive discharges having an expanding chamber when negative ions are present: i the source instability, occurring in the neighborhood of the capacitive-to-inductive E to H transition, and ii the downstream instability, which was shown to be the periodic formation and propagation of double layers. These unstable double layers were found...
It is well-documented that certain oxides (such as Re2O7, B2O3, MoO3, V2O5, etc.) can provide friction coefficients of 0.1-0.3 to sliding surfaces at elevated temperatures and thus they are often referred to as lubricious oxides in the tribology literature. In a recently proposed crystal chemical model, Erdemir was able to establish a close correlation between the reported friction coefficients...
We have successfully developed a new synthetic approach to modulate the electrostatic potentials of metallocavitands and thus their selective recognition towards substituted benzene derivatives via integrating two metal cations of different electronegativity into a self-assembled system.
This paper calls attention to the early work of the American chemists Worth Rodebush and Groves Cartledge, and their anticipations of a quantitative electronegativity scale, which predate the classic 1932 paper of Linus Pauling by several years.
