These systems will provide the cosmetic industry with new types of formulations which are easier to apply, better functional benefit and potentially safer formulations. Microemulsions are thermodynamically stable systems and hence shelf life is no problem. Many cosmetic ingredients can be adequately solubilized in the swollen micelles of the microemulsions. Such solubilized systems may enhance transport and diffusion through various barriers, eg., the skin, thus enhancing the efficacy of the formulations. However, microemulsions may cause skin irritation by disrupting the liquid crystalline structure of the stratum corneum. This problem may be overcome by formulating microemulsions, which on evaporation produce lamellar liquid crystalline structures. The problem of skin irritation is certainly reduced or eliminated using liposomes or vesicles, which offer an alternative to microemulsions. The principles for formation and stabilization of vesicles are discussed in this paper and research work is needed to produce nanocapsules from liposomes, using polymerizable surfactants. Multiple emulsions of the water/oil/water (w/o/w) or oil/water/oil (o/w/o) types are also valuable systems for formulating cosmetics. In the first place, they offer a means of sustained release of the various ingredients. Secondly, they allow one to separate the various ingredients in the formulation, thus preventing their possible interaction. The basic principles required for preparation of stable multiple emulsions are summarised. Developments of polymeric surfactants led to the formulation of stable multiple emulsions. An example of a recently formulated stable w/o/w multiple emulsion is given in this paper The stability of the system was investigated using optical microscopy. Creaming occurred on storage, particularly at high temperature (40°C) and this was significantly reduced by addition of Kelzan (a polysaccharide with high molecular weight). The final formulation was studied rheological techniques.

Water-based high crystalline TiO2 nanoparticle suspension was prepared via a gel-sol method at a basic pH. The TiO2 nanoparticles have an average size of 20 nm and are stable against agglomeration. As-prepared TiO2 nanosuspension is ready to be well dispersed in commercial waterborne acrylic resin system without extra-surface modification. The fabricated TiO2/acrylic nanocomposite coating achieved a UV cut-off below 350 nm with a visible transmission greater than 85% at 700 nm. It is also demonstrated by using Rhodamine 6G that surface modification of nano-TiO2 with a SiO2 insulation layer would suppress the catalytic activity of nano-TiO2 and improve the UV protection for UV and photocatalysis sensitive dyes.

GraphèneLe graphène est un cristal bidimensionnel (monoplan) de carbone dont l'empilement constitue le graphite. Il a été isolé en 2004 par Andre Geim, du département de physique de l'université de Manchester, qui a reçu pour cette découverte le prix Nobel de physique en 2010 avec Konstantin Novoselov. Il peut être produit de deux manières : par extraction mécanique du graphite (graphène exfolié) dont la technique a été mise au point en 2004, ou par chauffage d'un cristal de carbure de silicium, qui permet la libération des atomes de silicium (graphène epitaxié). Record en conduction thermique jusqu'à 5300 W.m-1.K-1. C'est aussi un matériaux conducteur.

PolyacrylonitrileIndex. décimale : 677.4 Textiles artificiels Résumé : The fabrication of graphene nanoribbon (GNR)/carbon composite nano-fiber yarns by electrospinning of graphene oxide nanoribbon (GONR)/PAN composites, foilowed by successive twisting and carbonization are demonstrated. The electron micrograph analysis showed that the well-dispersed nanoribbons were highly oriented along the fiber axis in the electrospun fibers. A low weight fraction of the GONR improved the mechanical properties of the polymer composite nanofiber yarns. In addition, carbonization significantly enhanced the mechanical and electrical properties. At present, the optimization of the GNR/carbon composite nanofibers is not accomplished. It is expected that better physical properties can be attained by optimization of spinning conditions (e.g. spinning solutions containing a higher content of well-dispersed GONR or higher-aspect-ratio ones) and carbonization conditions. The GNR composite (nano-)fibers and textiles could be applied to reinforcements for lightweight composites. ln particular, GNR/carbon composites could be utilized for high-performance electrodes for fuel cells, secondary batteries and supercapacitors, fiber and textile-shaped solar tells, including flexible and wearable electronic devices and implantable medical devices.
