A group of crosslinked poly(N-isopropylacrylamide-co-acrylic acid) (P(NIPAM-co-AAc)) microgels with different amount acrylic acid (AAc) were synthesized by surfactant-free emulsion polymerization. The morphology and environmental sensitivity studied atomic force microscope (AFM). It was founded that the microgel particles monodispersed diameter dried latex about 800nm. Moreover, volume decrease...

The application of barium f&:e (BaFelZO19; BaF) in the magnetic media industry requires materials with strict control of homogeneity, morphology and magnetic properties resulting from their preparation and pretreatment. Here the use of water-in-oil microemulsions for the synthesis of nanoparticles of BaF is considered. Two microen~ulsions (containmg an aqueous phase, cetyltrimethylammonium brom...

The dynamics of water confined in two different types of reverse micelles are studied using ultrafast infrared pump-probe spectroscopy of the hydroxyl OD stretch of HOD in H2O. Reverse micelles of the surfactant Aerosol-OT (ionic head group) in isooctane and the surfactant Igepal CO 520 (nonionic head group) in 50/50 wt % cyclohexane/hexane are prepared to have the same diameter water nanopools...

The function of the lung is dependent upon differentiation and proliferation of respiratory epithelial cells and the synthesis/secretion of surfactant lipids and proteins into air space. During the respiratory inflammatory response, cytokines produced by macrophages and epithelial cells in the respiratory system have significant influence on surfactant protein homeostasis. We report here that a...

Microemulsions, comprising oil, water and a surfactant, in association with some co-surfactant, are thermodynamically stable systems. They have found applications large number of chemical pharmacological processes due to their unique properties such as interfacial area, low tension, most importantly, the ability solubilize deliver hydrophobic drugs. In addition oral intravenous route, they suit...

Microemulsions are clear transparent, thermodynamically stable dispersion of oil and water, stabilized by interfacial film of surfactant frequently in combination with a co-surfactant. Recently there has been a considerable interest for microemulsion formulation, for the delivery of hydrophilic as well as liphophlic drug as drug carriers because of its improved drug solubilisation capacity, lon...

This data article contains the data related to the research article "Characterization, biorecognitive activity and stability of WGA grafted lipid nanostructures for the controlled delivery of rifampicin" (Pooja et al. 2015) [1]. In the present study, SLN were prepared by a single emulsification-solvent evaporation method and the various steps of SLN preparation are shown in a flow chart. The pr...

This contribution presents the production of polymer-coated iron oxide magnetic nanoparticles carrying functional groups on their surface and their basic characterization. The preparation of polymer-coated nanoparticles was carried out by a two-step process. In the first step, magnetite (Fe3O4) nanoparticles were prepared by a co-precipitation method from the solutions of FeCl2.4H2O and FeCl3.6...

In this study, tretinoin microemulsion has been formulated based on phase diagram studies by changing the amounts and proportions of inactive ingredients, such as surfactants, co-surfactants and oils. The effects of these variables have been determined on microemulsion formation, particle size of the dispersed phase and release profile of tretinoin from microemulsion through dialysis membrane. ...
