Monodisperse w/w/w double emulsion induced by phase separation.
We develop an approach to fabricate monodisperse water-in-water-in-water (w/w/w) double emulsion in microfluidic devices. A jet of aqueous solution containing two incompatible solutes, dextran and polyethylene glycol (PEG), is periodically perturbed into water-in-water (w/w) droplets. By extracting water out of the w/w droplet, the solute concentrations in the droplet phase increase; when the c...
متن کاملPreparation and Evaluation of Poly (s-caprolactone) Nanoparticles-in- Microparticles by W/O/W Emulsion Method
Objective(s) Theophylline, a xanthenes derivative, is still widely used as an effective bronchodilator in the management of asthmatic patients. It is used both as a prophylactic drug and to prevent acute exacerbations of asthma. The aim of study was to formulate and evaluate effect of the microencapsulation of theophylline loaded nanoparticles on the reduction of burst release. Materials and Me...
متن کاملA Colorimetric Determination of Blood Acetoin” by W. W. Westerfeldt
Most of the methods described for the determination of acetoin and biacetyl are based on the original Lemoigne-van Niel procedure (1, 2), which depends upon the formation of insoluble nickel dimethylglyoxime when biacetyl is treated with hydroxylamine in the presence of a nickel salt; acetoin is similarly determined after oxidation to biacetyl by heating with ferric chloride. In a recent modifi...
متن کاملT Violation Induced by Supersymmetry in tt̄ and W + W −
T -odd correlations of polarizations and momenta provide a promising testing ground for new physics beyond the standard model. We estimate the contribution of the minimal supersymmetric extension of the standard model to two such observables: in the production of tt̄, we look for a term proportional to Jt · ( pq × pt ) —where Jt is the polarization of the t quark and pq,t are the momenta of the ...
