Thin-layer chromatographic separation of penicillins has been performed on stannic arsenate–cellulose layers. RF values of penicillins were determined after use of different mobile phases. Amoxycillin and ampicillin were selectively separated from binary and ternary synthetic mixtures. Amoxycillin and ampicillin in commercially available drugs were also separated and were quantitatively determi...

mechanical alloying of binary and ternary elemental powder mixtures with the nominal compositions of mg2ni and mg(2-x)mnxni (x= 0, 0.05, 0.10 and 0.15 at. %) were carried out in a planetary ball mill for various milling times of 5, 10, 15, 20, 30 and 60 h. x-ray diffraction and field emission scanning and transmission electron microscopy were used for the characterization of the milled products...

A quantitative procedure was developed to predict the composition of ternary ground spice mixtures using an electronic nose. Basil, cinnamon, and garlic were mixed in different compositions and presented to an enose. Nineteen training mixtures were used to build predictive models. Model performance was tested using 5 other mixtures. Three neural network structures—multilayer perceptron (MLP), M...

Temperature-dependent viscosity, conductivity and density data of ternary mixtures containing 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)azanide (EMIM-TFSA), ethylene carbonate (EC), and lithium bis(trifluoromethanesulfonyl)azanide (Li-TFSA) were determined at atmospheric pressure in the temperature range of 20 to 80 °C. Differential scanning calorimetry (DSC) measurements were pe...

In spite of considerable research on the nature of aqueous alcohol mixtures that are characterized by microscopic inhomogeneity or incomplete mixing at the molecular level, transport properties have received little attention. We report the results of a study on diffusion in the ternary mixture of water with two alcohols, that is, water + methanol + ethanol, which is investigated on microscopic ...
