This paper studies the application of principal component analysis, multiple polynomial regression, and artificial neural network ANN techniques to the quantitative analysis of binary mixture of dye solution. The binary mixtures of three textile dyes including blue, red and yellow colors were analyzed by PCA-Multiple polynomial Regression and PCA-Artificial Neural network PCA-ANN methods. The o...

We investigate the behavior of colloidal particles immersed in a binary liquid mixture of water and 2,6-lutidine in the presence of a chemically patterned substrate. Close to the critical point of the mixture, the particles are subjected to critical Casimir interactions with force components normal and parallel to the surface. Because the strength and sign of these interactions can be tuned by ...

A simple and accurate method to determine pitavastatin calcium (PIT) and ezetimibe (EZE), in binary mixture, was developed and validated using liquid chromatography (LC). The LC separation was achieved on a Phenomenex Luna C18 column (250 mm, 4.6mm i.d., 5μm), in the isocratic mode using 0.1 % orthophosphoric acid: acetonitrile: triethylamine (19.8: 80: 0.2, v/v/v), pH 3 ± 0.05, at a flow rate ...

A simple and accurate method to determine Darunavie ethanolate (DRV) and ritonavir (RTV), in binary mixture, was developed and validated using liquid chromatography (LC). The LC separation was achieved on a Phenomenex Luna C18 column (250 mm, 4.6mm i.d., 5μm), in the isocratic mode using acetonitrile: water (60: 40, v/v), pH adjusted to 3.2 ± 0.02 with formic acid at a flow rate of 1 mL/min. Th...

We present results from an extensive experimental investigation into granular segregation of a shallow binary mixture in which particles are driven by frictional interactions with the surface of a vibrating horizontal tray. Three distinct phases of the mixture are established viz. binary gas (unsegregated), segregation liquid, and segregation crystal. Their ranges of existence are mapped out as...

Distillation is a physical process used to separate a fluid mixture of two (binary) or more (multicomponent) substances into its component parts. In most cases, the components to be separated are miscible liquids with different volatilities and boiling points. This separation process is a thermal unit operation that utilizes the differences of vapour pressure to produce the separa‐ tion. In thi...

We derive effective interaction potentials between hard, spherical colloidal particles and star-branched polyelectrolytes of various functionalities f and smaller size than the colloids. The effective interactions are based on a Derjaguin-like approximation, which is based on previously derived potentials acting between polyelectrolyte stars and planar walls. On the basis of these interactions...

An amplified cholesteric liquid crystal (CLC) laser performance is demonstrated by utilizing a binary-dye mixture (with 62 wt% DCM and 38 wt% PM597) as the active medium and an external stable resonator. The measured results show that the laser efficiency is enhanced as compared to the highest efficiency of each individual dye. Furthermore, using such an active CLC in an external stable resonat...
