The effect of long chain alcohols (5 mol% CnOH for n = 8, 10, 12, 14, and 16) on the micellar stability of sodium dodecyl sulfate (SDS) solutions (SDS concentration ranging from 25 to 200 mM) was investigated and related to foaming properties, such as foamability, dynamic and equilibrium surface tension, and surface viscosity. The slow micellar relaxation time tau2, which is directly related to...

Tricine–SDS-PAGE is commonly used to separate proteins in the mass range 1–100 kDa. It is the preferred electrophoretic system for the resolution of proteins smaller than 30 kDa. The concentrations of acrylamide used in the gels are lower than in other electrophoretic systems. These lower concentrations facilitate electroblotting, which is particularly crucial for hydrophobic proteins. Tricine–...

A comparative study of peak shape, elution behavior, and resolution of 16 beta-blockers (acebutolol, alprenolol, atenolol, bisoprolol, carteolol, celiprolol, esmolol, labetalol, metoprolol, nadolol, oxprenolol, pindolol, practolol, propranolol, sotalol, and timolol) chromatographed with hybrid mobile phases of triethylamine (TEA)-acetonitrile and sodium dodecyl sulfate (SDS)-propanol is perform...

Surfactants are synthetic organic chemicals that are formulated to have cleansing or solubilisation properties with the development of the industrial economy and increase in population density, surfactants have become one of the most widely disseminated xenobiotics to enter the aquatic environment, creating a serious environmental problem. Principal criterion for the ecological behavior of surf...

The electron paramagnetic resonance absorption of nitric oxide hemoglobin was observed as a possible model system for oxyhemoglobin. The electron paramagnetic resonance spectrum showed three g factors indicating a rhombic symmetry around the paramagnetic center. By use of 15N0, the unpaired electron was found very little associated with NO nitrogen, in contrast to what has been customarily assu...

−The purpose of this investigation was to enhance the dissolution rate of loratadine using polyethylene glycol 6000 (PEG) solid dispersions (SDs). The solubility behavior of loratadine in the presence of polyethylene glycol 4000 and polyethylene glycol 6000 in water showed linear increase with increasing concentrations of PEG, indicating AL type solubility diagrams. SDs of loratadine with PEG 6...

Micellisation process for sodium dodecyl sulphate and sodium cholate in 1∶1 molar ratio was investigated in a combined approach, including several experimental methods and coarse grained molecular dynamics simulation. The critical micelle concentration (cmc) of mixed micelle was determined by spectrofluorimetric and surface tension measurements in the temperature range of 0-50°C and the values ...

Introduction. Gallic acid is a biologically active natural compound with strong antioxidant properties. highly soluble and stable. It known to increase the thermal stability of protein. However, its bioavailability low, but interaction proteins can solve this problem. Bovine serum albumin bind various ligands, including polyphenols. The resulting complex gallic bovine become promising functiona...

We reconsider the widely held view that Mannheim--Kazanas (MK) vacuum solution for a static, spherically-symmetric system in conformal gravity (CG) predicts flat rotation curves, such as those observed galaxies, without need dark matter. This prediction assumes test particles have fixed rest mass and follow timelike geodesics MK metric region exterior to representation of galactic distribution....
