We use a micro-device where micro-droplets of reagents are generated and coalesce in a carrier continuous phase. The work focuses on the characterization of the mixing step inside the droplets, in the perspective to use them for chemical kinetic data acquisition. A dye and water are used, and an acid-base instantaneous chemical reaction is monitored thanks to a colored indicator. Acquisitions a...

BACKGROUND Polymers are attractive materials for both biomedical engineering and cardiovascular applications. Although nano-topography has been found to influence cell behaviour, no established method exists to understand and evaluate the effects of nano-topography on polymer-blood interaction. RESULTS We optimized a micro-fluidic set-up to study the interaction of whole blood with nano-struc...

In this paper, we have studied the electrical properties of the randomly distributed metallic (Co and Fe) nano/ micro wires on Silicon substrate. Deposition was carried out potentiostatically into the pores of the track-etch polycarbonate membrane spin coated onto the Si substrate. Spin coated films were irradiated with 150MeV Ni (+11) ions at a fluence of 8E7 ions/cm2, followed by UV irradiati...

Polymer microlenses have been manufactured by delivering droplets of a monomer mixture to a glass substrate using a nano fountain pen (NFP). Subsequent UV polymerization yielded microlenses with optical properties that were controlled by varying the deposition time of the monomer solution. Using this approach, it is possible to strategically place single microlenses at predefined positions with...

according to recent achievements in nano technology we can see its effects in different engineering fields. in nano manufacture process the first essential step is modeling coordinately in order to make it available different software are developing for this propose.  in this paper nano modeling for two papers is developed first understanding structure in nano and micro size and second simulati...

Several methods for rendering and modeling water have been made and a few of them address the natural phenomenon of water droplets flow. As far as we know, none of those methods have used bump maps in order to simulate the flow of a droplet on structured surfaces. The normals of the bump map, that describes the geometry of the micro structured surface, are used in the flow computation of the dr...

We already reported that genetically engineered resveratrol-enriched rice (RR) showed to down-regulate skin melanogenesis. To be developed to increase the bioactivity of RR using calli from plants, RR was adopted for mass production using plant tissue culture technologies. In addition, high-pressure homogenization (HPH) was used to increase the biocompatibility and penetration of the calli from...

Compared with UV embossing and micro-contact imprinting, hot embossing technology is the first to be used in nano-imprint lithography, and is access to copying the parallel structure in micro-nano-scale at low cost and relatively faster speed. This paper explores which factors influence some pattern transferring accuracy appearing in the experiment: the adhesion between mold and polymethyl meth...
