Apr 01, 1993 X-ray microanalysis is sufficiently sensitive, and has adequate resolution, to measure these concentrations. The major difficulties are related to the preparation of material for analysis. We have compared the measurement of sodium, potassium, and chloride contents in a salt tolerant unicellular alga, Dunaliella parva, following either freeze-substitution (using two …

Feb 11, 2020 Summary: Molecular Distillation Apparatus is a special liquid-liquid separation technology. In a high vacuum state, it makes the average free path of vapor molecules larger than the distance between the evaporation surface and the condensation surface, so that the difference in evaporation rate of each component in the material liquid can be used to …

In this work, important results from simulations are presented, showing the potentiality of the molecular distillation process for recovering vitamin E from vegetal oils. Two types of molecular distillators are considered: falling film and centrifugal. The results emphasize the degree of recovery and factors that influence substantially the performance of the molecular distillators, …

Molecular distillation is a distillation method operated under high vacuum. At this time, the average free path of the vapor molecules is greater than the distance between the evaporation surface and the condensation surface, so that the difference in the evaporation rate of each component in the liquid can be used for liquid mixtures.

What is the principle of molecular distillation? - Lab ...

Molecular distillation is a type of short-path vacuum distillation, characterized by an extremely low vacuum pressure, 0.01 torr or below, which is performed using a molecular still. It is a process of separation, purification and concentration of natural products, complex and thermally sensitive molecules for example vitamins and polyunsaturated fatty acids.

Molecular Dynamics and Monte Carlo - CCL

Molecular dynamics, contrary to energy minimization in molecular mechanics, is able to climb over small energy barriers and can drive the system towards a deeper energy minimum. The use of molecular dynamics allows probing of the potential energy surface for deeper minima in the vicinity of the starting geometry.
