Collision dynamics of excited NaK. I. Reactive KNaK and elastic HeNaK collisions
Chemical Physics, 1980Abstract The collision dynamics of excited NaK have been studied using the technique of circularly polarised laser fluorescence. A very unusual m -dependent rate is observed for KNaK* reactive or quenching collisions which is different depending on whether the initial excitation is via Q or P, R transitions. A model is presented attributing this to

Abstract NAK 55 is a very clean steel for use in plastic and rubber molds were impact resistance is not critical in design. Its age-hardening gives very high strength and good wear resistance. Tight tolerance are obtained with consistent expansion and contraction properties.

Abstract NAK 80 is a precipitation-hardened tool steel for molds with a similar through hardness. The alloy is used when exceptional polishing is required. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness.

Physical Review, 1934
The spectrum of the NaK molecule has been studied in absorption and in magnetic rotation throughout the visible and photographic infrared regions. By means of magnetic rotation the upper vibrational levels of the orange system have been followed nearly to dissociation, permitting accurate determinations of the energies of dissociation of four states of

Abstract Millimeter- and submillimeter-wave spectroscopy was applied to an alkali heterodimer molecule NaK. The NaK molecule was generated in a heated stainless steel pipe, which also served as an absorption cell. Rotational transitions of J = 14 to 69 were observed for the vibrational states of v = 0 to 6 in the ground electronic state. A set of

CCCP activation of the reconstituted NaK-pump
The Journal of Membrane Biology, 1990In the NaK-ATPase proteoliposomes (PLs), the NaK-pump activity, Na+ uptake, and ATP hydrolysis were apparently enhanced by carbonyl cyanide m-chlorophenyl hydrazone (CCCP) and other ionophores without ion gradients. These ionophore effects were not cation specific. Without ionophores, the PL's ATPase activity fell to its steady-state value within 3 sec

As part of the NASA orbital debris modeling effort, a quantitative model is developed for the large population of spherical electrically conducting objects in 65° inclination circular orbits at the disposal altitude of the Russian Radar Ocean Reconnaissance Satellite (RORSAT) spacecraft. These are believed to be droplets of liquid sodium-potassium (NaK)
