Experimental data on the kinetics of propane hydrate dissociation at 0.1 MPa and different external temperatures were obtained. A two-stage mechanism of hydrate dissociation was observed visually. In the first stage hydrate dissociated into metastable water and gas. During the second stage the metastable water crystallized into ice. The release of metastable water during hydrate dissociation an...

We have found corundum in direct contact with quartz and biotite as inclusions garnet the pelitic gneisses of northern Austkampane Northeastern (NE) Terrane Sør Rondane Mountains (SRM), East Antarctica. Our samples, which include corundum–bearing gneisses, show petrographic features such staurolite garnet, compositional zoning orthoamphibole Al decreasing toward rims, late–stage cordierite form...

Abstract α -RuCl 3 is a major candidate for the realization of Kitaev quantum spin liquid, but its zigzag antiferromagnetic order at low temperatures indicates deviations from model. We have quantified Hamiltonian by resonant inelastic x-ray scattering study Ru L absorption edge. In paramagnetic state, quasi-elastic intensity magnetic excitations has broad maximum around zone center without any...

This article presents a new experiment aiming at BEC of metastable helium atoms. It describes the design of a high flux discharge source of atoms and a robust laser system using a DBR diode coupled with a high power Yb doped fiber amplifier for manipulating the beam of metastable atoms. The atoms are trapped in a small quartz cell in an extreme high vacuum. The trapping design uses an additiona...
