Research ArticleOpen accessEvery word in the titleSpeed of Sound and Apparent Molal Volume Approach to Study the Ion-Solvent Interactions in Pharmaceutically Important Liquid SystemsD.N. Ganesh, Vinay S. Bhat, Susmita KamilaPresence of zinc ion and lactose in different pharmaceutical compositions have been inspired to investigate the ion-solvation and related interactions among the components in solution media. This study has been carried out by the measurements of ultrasonic velocity, viscosity and density for the binary solutions of zinc sulphate (ZnSO4) in lactose-water mixed solvent systems at 303.15, 308.15, 313.15 K temperature … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 21 Apr 2020 · 7,597 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleImprovements on Semi Critical Assisted-Solvent Extraction of Biocrude Oil from Spirogyra. sp Macro AlgaeTulio Chavez-Gil, Hany F. Sobhi, Alexis Pacheco-LaracuenteHere, we report on an improved chemical method to extract hydrocarbons (CH) and Fatty Acid Methyl Esters (FAME) from wild green macro algae, which is higher than that carried out with conventional Soxhlet (Sx) and similar to that of Subcritical (SbC) or supercritical fluid (SCE) extraction methods. Crude oil plus residual biomass gave combined calorific values of 49.05 MJ/kg in … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 18 Apr 2018 · 10,083 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleMixed-Polarity Azeotropic Solvents for Efficient Extraction of Lipids from Nannochloropsis MicroalgaeRobert D. Long, Elseddik AbdelkaderProblem statement: The extraction of lipids from microalgae for biofuel production is a significant problem due to the intractability of their cell wall. The aim of this study of lipid extraction from Nannochloropsis microalgae was to examine the relative efficiencies of some commonly used solvent systems and test the use of co-boiling solvents in Soxhlet extraction as an improved method. … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 2 · 12 Aug 2011 · 9,387 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleFactor Analysis, Target Factor Testing and Model Designing of Aromatic Solvent Effect of the Formyl Proton Nuclear Magnetic Resonance Chemical Shift in Para substituted BenzaldehydesGhazwan F. FadhilProblem statement: The variations of formyl proton Chemical Shifts (CS) of p-substituted benzaldehydes in aromatic solvents were investigated. The validity of several physical solvent and empirical solvent scales was examined. Also, to predict dipolarity-polarizability (π*) solvent scale for some aromatic solvents. Model designing was also achieved to rationalize the aromatic solvent effect on the formyl proton CS. Approach: The previously … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,582 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleStudy of the Optical and Physical Roles of a Dielectric Laser Dye Solvent Which Affects on the Dye Laser OperationRiyad A.M. GhazyIt is well known that when the pump laser beam incidence on the laser dye liquid it will be absorbed. This absorption tends to heat the laser active medium, which is the laser dye solution. In view of this the correlated property of that active medium well change tends to shift the operated frequency and wavelength. Therefore, one of most … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,862 accessesView PDF Cite
