An experimental investigation of the motion of flexible molecules in the liquid state by light scattering
… component is examined for n-alkanes, both pure liquids and solutions in CC1(4), the n-alcohols, both pure liquids and solutions in CC1(4), the n-alcohols, and the isomer 224-trimethyl pentane. For the low viscosity liquids this component is Lorentzian. For the higher viscosity liquids the …

Electrohydrodynamic Manipulation of Sessile Droplets by the In-Plane Electric Fields
… applied) on sessile droplets of multiple pure liquids, solvents, colloidal suspensions (with particles and pigments) and conducting polymers commonly used in painting and coating processes. This fundamental research aims at understanding the principles and mechanisms of interaction of the …

The drying of small drops of particulate slurries
The literature on the evaporation of drops of pure liquids, drops containing solids and droplet sprays has been critically reviewed. An experimental study was undertaken on the drying of suspended drops of pure water and aqueous sodium sulphate decahydrate with concentrations varying from 5 to 54. …

A study of the drying of single droplets in free-flight
… relating to evaporation from single droplets of pure liquids and the drying of solution and slurry droplets, and of droplet sprays has been reviewed. The heat and mass transfer rates for individual droplets suspended in free-flight, were investigated using a specially-designed vertical wind …

The distribution of local enhancement factors in surface enhanced Raman-active substrates and the vibrational dynamics in the liquid phase
… Previously our group focused on nontoxic pure liquids, but now we are able to study aqueous solutions and precious or toxic liquids with the use of an upgraded laser system. In particular, I worked with my colleagues to successfully compare the vibrational dynamics between benzene and …

Mechanisms of drying of skin forming materials
… relating to evaporation from single droplets of pure liquids, and to the drying of droplets containing solids and of droplet sprays has been reviewed. The heat and mass transfer rates for a single droplet suspended from a nozzle were studied within a 42mm I.D. horizontal wind tunnel designed to …

Nuclear magnetic resonance spectroscopy and ultrasound
… Ultrasonic perturbation of T1 is far smaller for pure liquids than is for mixtures. The effects appear to be greater on protons (1H) than on carbon-13 nuclei (13C) relaxation times. The observed effect of ultrasonics is not due to temperature changes in the sample. As the power applied to the …

Applications of supercritical fluids to the extraction and analysis of oligomers and polymer additives
… solvating strengths that can approach those of pure liquids while maintaining many of the advantageous transport qualities of gases. In the past decade SFs have seen increased use as solvents for both extraction (SFE) and chromatography (SFC). A particularly exciting area of applications has …

Experimental Investigation of Jet Breakup at Low Weber Number
… viscosity were investigated by using two viscous liquids (ethylene glycol and propylene glycol) apart from water. Nozzle diameters from 0.279 mm to 1.753 mm were used to study its influence on the liquid jet breakup. </p><p>Results show that the jet breakup patterns for water at lower Weber …

Physical properties, evaporation and combustion characteristics of nanofluid-type fuels
<p>Nanofluids are liquids with stable suspension of nanoparticles. Limited studies in the past have shown that both energetic and catalytic nanoparticles once mixed with traditional liquid fuels can be advantageous in combustion applications, e.g., increased energy density and shortened ignition …
