In this work needle like hydroxy apatite were synthesized in a reverse microemulsion droplets of water in cyclohexane, separated by a cationic surfactant and co-surfactant, in the presence of Na-polyacrylate (PAA) as an anionic polyelectrolyte. Characterization of the as formed HAp nanoparticles at the room temperature were carried out by X-ray diffraction (XRD) and Fourier transform infrared s...

Liquids condensing on solids can form a pattern known as ‘‘breath figures.’’ Here we report similar patterns for liquid boron oxide droplets formed by high temperature oxidation reaction of boron nitride. Boron oxide does not wet boron nitride, so the liquid B2O3 oxide forms small droplets. As oxidation proceeds at 12001C, the oxide created by reaction on the surface migrates to existing drople...

We report the use of flow cytometry to identify the internal ordering (director configurations) of micrometer-sized droplets of thermotropic liquid crystals (LCs) dispersed in aqueous solutions of adsorbates (surfactants and phospholipids). We reveal that changes in the configurations of the LC droplets induced by the adsorbates generate distinct changes in light scattering plots (side versus f...

Changes in the number of lipid droplets during meiotic maturation, fert i l ization and early development were histochemically examined in cultured porcine oocytes and embryos. The oocytes and embryos possessed Sudanophilic lipids composed of small (<2.5 μm), medium (2.5–4.9 μm) and large (≥5.0 μm) droplets. In oocytes soon after collection, the numbers of Sudanophilic lipid droplets with small...

BACKGROUND The Influenza A H1N1 virus can be transmitted via direct, indirect, and airborne route to non-infected subjects when an infected patient coughs, which expels a number of different sized droplets to the surrounding environment as an aerosol. The objective of the current study was to characterize the human cough aerosol pattern with the aim of developing a standard human cough bioaeros...

BACKGROUND Histones are essential for chromatin packing, yet free histones not incorporated into chromatin are toxic. While in most cells multiple regulatory mechanisms prevent accumulation of excess histones, early Drosophila embryos contain massive extranuclear histone stores, thought to be essential for development. Excess histones H2A, H2B, and H2Av are bound to lipid droplets, ubiquitous f...

In line with recent ongoing efforts to collect crucial information about the mechanisms of virus diffusion and put them in relation effective complexity several natural or artificial environments where human beings leave operate, present study deals dispersion evaporating saliva droplets cabin an interregional train. A relevant physical model is constructed taking into account state art terms e...

In digital microfluidic systems, analyte droplets (volume typically á1μl) are transported on a planar electrode array by dielectrophoretic and electrowetting effects. While recent work has demonstrated feasibility mainly with single droplets on small arrays, these systems hold promise for commercial-scale applications by simultaneously moving many droplets on large arrays. This paper introduces...
