A multi-scale framework is proposed for more realistic molecular dynamics simulations in continuum solvent models by coupling a molecular mechanics treatment of solute with a fluid mechanics treatment of solvent. This article reports our initial efforts to formulate the physical concepts necessary for coupling the two mechanics and develop a 3D numerical algorithm to simulate the solvent fluid ...

Olive leaves are an agricultural waste of the olive-oil industry representing up to 10% of the dry weight arriving at olive mills. Disposal of this waste adds additional expense to farmers. Olive leaves have been shown to have a high concentration of phenolic compounds. In an attempt to utilize this waste product for phenolic compounds, we optimized their extraction using water-a "green" extrac...

The mother liquor from which a biomolecular crystal is grown will contain water, buffer molecules, native ligands and cofactors, crystallization precipitants and additives, various metal ions, and often small-molecule ligands or inhibitors. On average, about half the volume of a biomolecular crystal consists of this mother liquor, whose components form the disordered bulk solvent. Its scatterin...

Literature survey reveals that few analytical methods were reported for the estimation of cinacalcet hydrochloride by LC, UV methods. Hence the present study aims in developing simple, rapid, precise and validated methods for cinacalcet hydrochloride in bulk. The methods are Colorimetric determination of Cinacalcet Hydrochloride by Visible Spectrophotometric method, Validation of Cinacalcet Hyd...

A reliable and simple procedure to extract polychlorinated biphenyls (PCBs) from marine mussels using microwave energy is proposed. Freeze-dried mussels were subjected to MASE (Microwave Assisted Solvent Extraction) in a closed-vessel microwave system with n-pentane-sodium hydroxide (5 %) or dichloromethane-pentane (1:1) at different temperatures (70 and 90 oC), the extraction time was 10 minut...

dispersive liquid liquid microextraction (dllme) combined with gas chromatography–mass spectrometry (gc–ms) was used for the extraction and determination of 13 polycyclic aromatic hydrocarbons (pahs) in mineral water samples. in this procedure, the suitable combination of extraction solvent (500 µl chloroform) and disperser solvent (1000 µl acetone) were quickly injected into the water sample (...
