it is possible by fractional crystallization to separate off a solid in which the concentration in respect of said element has become C.sub.S and such that C.sub.S is lower than C.sub.L. That phenomenon has been applied to the purification of metals, in particular to remove therefrom ...
In an early stage of the evolution, where olivine and/or pyroxenes are the fractionating phases, compositional stratification can occur due to side-wall crystallization and replenishment by new magma, with the most differentiated magma tending to accumulate at the roof of the chamber. When ...
When a constriction is realized in a 2D quantum spin Hall system, electron tunneling between helical edge states occurs via two types of channels allowed b... P Sternativo,F Dolcini - 《Physical Review》 被引量: 4发表: 2014年 Quantum Hall states in inverted HgTe quantum wells probed by tr...
The paper aims to investigate the channel flow of second grade visco-elastic fluid generated due to an oscillating wall. The effect of heat and mass transfer has been taken into account. The phenomenon has been modelled in terms of PDEs. The constitutive equations are fractionalized by using th...
The separation of component in a liquid mixture of the crystalline solid by fractionation wherein crystallizes and occurs on the outer surface of a pipe when refrigerant fluid expands, cooling, then top from wherein it benefit bottom splash hole. Crystal is removed in second phase, and wherein...
It has been suggested that evolution of a terrestrial magma ocean does not unavoidably follow a fractional crystallization scenario. Convection is able to preclude differentiation until a sharp viscosity increase occurs near some critical crystal fraction. However, this kind of crystallization and its ...
The occurrence of calcite and silicate minerals (pyroxene, titanite, nepheline and alkali feldspar) in equilibrium indicates simultaneous crystallization of these phases. This situation is only possible when the CO2-rich silicate melt reaches the composition marked by the boundary between the silicates an...
