Although the vapor-liquid-solid growth of semiconductor nanowire is a non-equilibrium process, the equilibrium phase diagram of binary alloy provides important guidance on the growth conditions, such as the temperature and the equilibrium composition of the alloy. Given the small dimensions of the alloy seeds and the nanowires, the known phase diagram of bulk binary alloy cannot be expected to ...

the nain and ashin ophiolites are located in northeastern isfahan province, in western central-east iranian microplate. pillow lavas are one of the most significant cretaceous rock units. the lower partial melting degree in mantle peridotites of ashin ophiolite, and the derived melt by melting their clinopyroxene caused a more basic (basalt) and enriched nature for the ashin pillow lavas, where...

the extraction of gadolinium (gd) from perchlorate and nitrate media in 1,2-dichloroethane(c2h4cl2), carbon tetrachloride (ccl4) and chloroform (chcl3) by mixtures of 2-thenoyltrifluoroacetone (htta) and a crown ether benzo-15-crown-5 (b15c5) is investigated.the composition of the extracted species is determined as gd(tta)3.nb15c5 (n=1 in nitratemedium and n=2 in perchlorate medium). the values...

The equil ibrium ratio of 3.93 for pSi(OH4~ p K +] was significantly different from the ratio of 3.40 predicted by the equation for the dissolution o f muscovite of this particular composit ion in the presence of gibbsite. A new dissolution equation was derived in which the muscovite composit ion was adjusted to satisfy the solute activity data, the presumption being that muscovite of a new com...

Nicotinic acid (also known as pyridine-3-carboxylic acid) is widely used in food, pharmaceutical and biochemical industries. The extraction of nicotinic acid by tri-noctylphosphine oxide (TOPO) with kerosene (diluent) is studied. The equilibrium experiments are carried out to investigate the effects of diluent, extractant (TOPO) composition and initial acid concentration on extraction efficienc...

Abstract The kinetic patterns of the attainment equilibrium product composition in non-catalytic processes partial oxidation and steam carbon dioxide reforming hydrocarbons temperature range 1400–1800 K, characteristic these processes, were analyzed. need for such analysis is caused by rapidly increasing consumption natural gas as a chemical feedstock growing attention to environmental problems...

This work investigates the potential of coconut shell for air-steam gasification using thermodynamic equilibrium model. A thermodynamic equilibrium model considering tar and realistic char conversion was developed using MATLAB software to predict the product gas composition. After comparing it with experimental results the prediction capability of the model is enhanced by multiplying equilibriu...

Reversible computing is a paradigm of computation that extends the standard forward-only programming to reversible programming, so that programs can be executed both in the standard, forward direction, and backward, going back to past states. In this paper we present novel quantitative stochastic models for concurrent and cooperating reversible computations. More precisely, we introduce the cla...
