Clathration of Volatiles in the Solar Nebula and Implications for the Origin of Titan's atmosphere [PDF]

, 2008
We describe a scenario of Titan's formation matching the constraints imposed by its current atmospheric composition. Assuming that the abundances of all elements, including oxygen, are solar in the outer nebula, we show that the icy planetesimals were ...

Multilayer krypton phase diagram [PDF]

Physical Review B, 1993
We present vapor pressure and high-resolution heat-capacity measurements of multilayer krypton films adsorbed on graphite. We have found a complex phase diagram including reentrant layering transitions for coverages higher than three layers. The third layering transition does not end in a condensation critical point as was previously expected.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Numerical simulations of gas mixing effect in electron cyclotron resonance ion sources

Physical Review Accelerators and Beams, 2017
The particle-in-cell Monte Carlo collisions code nam-ecris is used to simulate the electron cyclotron resonance ion source (ECRIS) plasma sustained in a mixture of Kr with O_{2}, N_{2}, Ar, Ne, and He.

Driving lamps by induction [PDF]

, 1973
An electrodeless lamp circuit with a coil surrounding a krypton lamp is driven by an RF input source. A coil surrounding a mercury lamp is tapped across the connection of the input central to the krypton-lamp coil. Each coil is connected in parallel with

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

High-pressure crystallography shows noble gas intervention into protein-lipid interaction and suggests a model for anaesthetic action

Communications Biology, 2022
Noble gases are known to interact with proteins and can be good anaesthetics in hyperbaric conditions. This study identifies argon and krypton binding sites on membrane proteins and proposes as a hypothesis that noble gases, by altering protein/lipid ...

Optical Radiation during Sputtering of Lithium into a Noble Gas Using a Nanosecond Electron Beam

Applied Sciences, 2023
The optical radiation in a gaseous medium upon the irradiation of a lithium layer with a fast electron beam of a 5 ns duration has been studied. The irradiation chamber was filled with argon, krypton, or xenon at a pressure of 10 kPa up to 60 kPa.

Krypton oxides under pressure [PDF]

Scientific Reports, 2016
AbstractUnder high pressure, krypton, one of the most inert elements is predicted to become sufficiently reactive to form a new class of krypton compounds; krypton oxides. Using modern ab-initio evolutionary algorithms in combination with Density Functional Theory, we predict the existence of several thermodynamically stable Kr/O species at elevated ...
