Water-in-oil (W/O) emulsion is one of the best "one-shot" delivery system for antigen to generate high and durable antibody response. Here a facile method using premixed Shirasu Porous Glass (SPG) membrane emulsification technique was employed to fabricate uniform-sized emulsion and mechanical stirring was employed to prepare non-uniform-sized emulsion as control. In release kinetics studies, u...

Fish oil-based emulsion is increasingly used in pediatric patients receiving Parenteral Nutrition (PN). However, its unique use in children on long-term PN is nutritionally debatable as some patients are better off with a mixture of long-chain (LCT) or long-chain + medium-chain (LCT + MCT) triglycerides along with Fish Oil (FO). Lipid emulsions are safely infused when particle diameter ranges b...

Using confocal microscopy, we study the flow of a model soft glassy material: a concentrated emulsion. We demonstrate the micro-macro link between in situ measured movements of droplets during the flow and the macroscopic rheological response of a concentrated emulsion, in the form of scaling relationships connecting the rheological "fluidity" with local standard deviation of the strain-rate te...

the present study involves preparation and evaluation of gastric-mucoadhesive microparticles with metformin hydrochloride as model drug for prolongation of gastric residence time. the microparticles were prepared by the emulsification solvent evaporation technique using polymers of carbomer 934p (c) and ethylcellulose (ec). the microparticles were prepared by emulsion solvent evaporation method...

Turbulent flow of water in a narrow gap of an emulsifier is investigated experimentally using micro-PIV (micro Particle Image Velocimetry) technique and compared with numerical predictions performed using the commercial code Fluent. The purpose of the investigations is to develop a procedure for wellcontrolled generation of mono-disperse suspension of micro droplets. These droplets will form a ...

A phenol aqueous emulsion allows the reassociation of DNA a t temperatures from 6 to 68 "C. This phenol emulsion reassociation technique (PERT) also promotes the very rapid reassociation of DNA. E . coli and human DNAs a t a concentration of 4 pg/mL reacted a t room temperature with the P E R T reassociate many thousand times faster than under the standard conditions of 0.18 M Na+, 60 O C . Sol...

Micro/sub-micron emulsion and related systems have received a lot of attention in the last years for their common use as vehicles for topical administration. These systems can be defined as fine emulsion dispersion with droplet sizes in the sub-micron range, and consisted of an aqueous phase, oily phase, and surfactants that are necessary for stabilizing the interface and forming the drops [1]....

A quat-silicone micro-emulsion (particle size <40 nm), an amino-silicone macro-emulsion (110 nm), and an alkyl modified silicone macro-emulsion (740 nm) were used to modify Scots pine (Pinus sylvestris L.) sapwood. Treated and uncoated boards were exposed to natural weathering for one year along with water treated controls according to EN 927-3. The treatment with silicone emulsions did not enh...

Micro-scale optical components play a crucial role in imaging and display technology, biosensing, beam shaping, optical switching, wavefront-analysis, and device miniaturization. Herein, we demonstrate liquid compound micro-lenses with dynamically tunable focal lengths. We employ bi-phase emulsion droplets fabricated from immiscible hydrocarbon and fluorocarbon liquids to form responsive micro-...
