Physicochemical properties of the heterogeneous system Li2CO3-Na2CO3-K2CO3/MgO [PDF]
The structure, conductivity, melting points and caloric melting effects of the (Li2CO3–Na2CO3–K2CO3)eut melt/MgO nanopowder heterogeneous system with MgO concentration up to 70 vol. % have been investigated. A wide variety of methods (DSC, XRD, BET, high

Low temperature stimulates spatial molecular reprogramming of the Arabidopsis seed germination programme [PDF]
The timing of the germination of seeds is highly responsive to inputs from the environment. Temperature plays a key role in the control of germination, with low temperatures acting to stimulate this developmental transition in many species.

Thermohaline structure and circulation beneath the Langhovde Glacier ice shelf in East Antarctica
Basal melting of ice shelves is the principal driver of recent ice mass loss in Antarctica. The study reports comprehensive structures of temperature, salinity and current under an ice shelf in East Antarctica obtained by borehole measurements.

Chaotic temperature dependence at zero temperature [PDF]
We present a class of examples of nearest-neighbour, boubded-spin models, in which the low-temperature Gibbs measures do not converge as the temperature is lowered to zero, in any ...

Nonlinear two-level dynamics of quantum time crystals
Recent work has reported a realization of a time crystal in the form of the Bose-Einstein condensate of magnons in superfluid 3He. Here, the authors study the dynamics of a pair of such quantum time crystals and show that it closely resembles the ...

Novel Nb5+-doped hexagonal perovskite Ba5In2Al2ZrO13 (structure, hydration, electrical conductivity)
The new phase Ba5In2Al2Zr0.9Nb0.1O13.05 with hexagonal perovskite structure was obtained. The substitution of Zr4+ by smaller Nb5+ was accompanied by the incorporation of the oxygen interstitials and did not lead to a significant change in the lattice ...

Borated graphite cathodes for low-temperature aluminum electrolysis
Electrochemical boriding of the graphite plates in the potassium cryolite based electrolytes was studied. The boriding were carried out in a cell with vertical electrodes. The procedure included 2 stages: 1) electrolysis in the KF–AlF3–KBF4 melt (CR=1.3)

Electrical conductivity of GdCl3-LiCl and GdCl3-LiCl-Gd2O3 molten systems [PDF]
The electrical conductivity of LiCl–GdCl3 molten systems with the gadolinium chloride additions ranging from 0 to 23 mol % was measured depending on both the temperature and concentration of GdCl3.
