Control of Zeolite Local Polarity toward Efficient Xenon/Krypton Separation.

Journal of the American Chemical Society
The inherent inertness and striking physicochemical similarities of krypton and xenon pose significant challenges to their separation. Reported herein is the efficient xenon capture and xenon/krypton adsorptive separation by transition metal-free ...

MAD phasing with krypton

Acta Crystallographica Section D Biological Crystallography, 2001
Experiments demonstrating the feasibility of Kr-edge MAD on frozen crystals as a routine method for structure determination are reported. Approximately 50% of protein crystals can be successfully derivatized by pressurization with the noble gases xenon or krypton. While Xe has produced many useful derivatives for MIR phasing over the last several years,

Krypton Derivatization of an O2 -Tolerant Membrane-Bound [NiFe] Hydrogenase Reveals a Hydrophobic Tunnel Network for Gas Transport.

Angewandte Chemie, 2016
[NiFe] hydrogenases are metalloenzymes catalyzing the reversible heterolytic cleavage of hydrogen into protons and electrons. Gas tunnels make the deeply buried active site accessible to substrates and inhibitors.

Viscosity and Thermal Conductivity of Binary Gas Mixtures: Krypton-Argon, Krypton-Neon, and Krypton-Helium [PDF]

Proceedings of the Physical Society, 1961
The coefficients of viscosity and thermal conductivity of binary mixtures of krypton with argon, neon and helium have been determined over the full range of composition of each mixture at a pressure of 70 cm of mercury and at a temperature in the range 18.0 to 18.3°C.

High-energy krypton fluoride lasers for inertial fusion.

Applied Optics, 2015
Laser fusion researchers have realized since the 1970s that the deep UV light from excimer lasers would be an advantage as a driver for robust high-performance capsule implosions for inertial confinement fusion (ICF).

Krypton tagging velocimetry of an underexpanded jet.

Applied Optics, 2015
In this work, we present the excitation/emission strategy, experimental setup, and results of an implementation of krypton tagging velocimetry (KTV). KTV is performed as follows: (i) seed a base flow with krypton; (ii) photosynthesize metastable krypton ...

Surface diffusion of metastable krypton atoms on krypton-doped solid argon

Journal of Luminescence, 1998
Abstract Besides desorption and surface trapping of selectively excited Kr atoms at the surface of Kr-doped Ar crystals, a new relaxation mechanism has been observed. It includes surface diffusion of long-living atomic-type surface centers and guest-molecule formation at the surface.
