Polyamide-66(PA66)/CaCO3 micro- and nano-composites were prepared using a polymer solution method at filler loading of 0, 1, 2 and 3 weight percent. Nano-size of CaCO3 was synthesized by micro-emulsion technique. The material was characterized by XRD, SEM, FTIR and UV-VIS techniques. XRD results of composites suggested that CaCO3 particles are found in the amorphous phase of the semi-crystallin...

A precise and simple in-situ voltammetric measurement of promethazine, based on the nano sized molecularly imprinted polymer (nano-MIP) was introduced. The nano-MIP was synthesized utilizing vinyl benzene and Divinylbenzene as the functional monomer and cross-linker respectively, and via the micro-emulsion polymerization method in silicon oil. The MIP particles were then embedded in a carbon pa...

We report enhanced electrochemical detection of single water-in-oil emulsion droplets using the nano-impact method. To detect droplets, water molecules in were directly oxidized (i.e., splitting) without additional electroactive species when collided with ultramicroelectrode. The droplet cannot be electrolyzed an organic solvent because emulsifier does not require a hydrophobic electrolyte. enh...

influenza is a contagious viral disease that is seen in avian, human and other mammals, so its control is important. vaccination against influenza virus subtype h9n2 is one of the ways in controlling program, for this reason several vaccines has been produced. recently, application of inactivated oil-emulsion vaccines in poultry for controlling low pathogenic avian influenza is increasing. at p...

ferulic acid (4-hydroxy-3-methoxycinnamic acid), an effective component of medical plant, is a phenolic acid with low toxicity that can be absorbed and easily metabolized in the human body. the solubility of ferulic acid (fa) is very low in aqueous solutions which can cause problem in preparation of pharmaceutical products, but it can easily be dissolved in oil/water interface of nano-emulsions...

Laboratory experiments were tested to detect the effect of crude camphor oil and its emulsion against 2nd instar larvae

Alginate microparticles and nanoparticles crosslinked with Ca+2 ions are frequently employed in biomedical applications. Here we use microemulsion polymerization to prepare alginate nanoparticles (nanogels) using different crosslinking ions (Ca+2, Sr+2, Ba+2) to encapsulate a model protein, urease enzyme (jackbeans). With alginate concentrations of 0.2wt% in the aqueous phase, emulsion droplets...

Emulsion stabilisation of base layers surfaced with chip seals often proves problematic, chips punching into the and early distress. This can be aggravated by use modified binders that restricts evaporation moisture from pavement layers. The introduction new-age (nano)-modified emulsion (NME) has advantage water is chemically repelled stabilised layer, resulting in an accelerated development st...
