We i nvestigate the optical phenomenon responsible for the colored shine that sometimes a ppears at the surface of ink layers i n t he s pecular direction, o ften ca lled bronzing or gloss di fferential. I t seems to co me from the w avelengthdependent refractive index of t he ink, which induces a wavelength-dependent reflectance of t he i nk-air interface. Our experiments o n c yan and magenta...

An innovative collection methodology based on a recently developed supersonic probe enabled the of alumina particulate from exhaust plume sub-scale solid propellant rocket motor and comparison with quench bomb analysis incipient agglomeration. Laser diffraction, scanning electron microscopy, X-ray spectroscopic methods were used to determine particle size, morphology, crystalline nature, elemen...

Composite materials achieved by including transition-metal oxides with different structures and morphologies in sulfur are suggested as scalable cathodes for high-energy lithium-sulfur (Li-S) batteries. The composites contain 80 wt.% 20 of either MnO2 or TiO2, leading to a content the electrode 64 revealing reversible, fast, lowly polarized conversion process cell limited interphase resistance....

The absorption of non-steroidal anti-inflammatory drugs (NSAIDs) through the nasal epithelium offers an innovative opportunity in field pain therapy. Thanks to bonding chitosan mucosa and its permeability-enhancing effect, it is excellent choice formulate microspheres for increase drug bioavailability. aim our work includes preparation spray-dried cross-linked non-cross-linked chitosan-based de...

A new family of self-assembling systems based on nucleoamphiphiles is described. Nano to micrometric left-handed helix formation in aqueous solution was induced simply by complexing a GMP or an AMP with a nonchiral monocationic amphiphile. The assembling behavior such as micellar formation, monolayer at air-water interface, as well as the aggregates in solution of these nucleoamphiphiles are st...

In this work a new system for immobilisation of cells was developed based on biocompatible alginate bariumfilms. Films are prepared to allow better control over film thickness and produce better film uniformity, avoiding roughness over film surface that can produce fibrosis and rejection after transplantation. In this study monocyte, mononuclear and fibroblast cell lines were immobilised in mic...
