Sol-gel, ProcédéIndex. décimale : 502.8 Techniques, procédés, appareils, équipement, matériaux Résumé : Le développement de techniques et de matériaux pour la nanofabrication constitue un secteur hautement stratégique dans le domaine de la microélectronique, de la photonique et de façon générale, dans le domaine des nanotechnologies et des nanosciences. Cet article présente trois techniques de nanofabrication récemment développées dans notre équipe : des nanostructures inorganiques préparées par interférométrie DUV, la nanophotopolymérisation en champ proche optique, et la nanofabrication par approches bottom-up et top-down combinées. À travers ces trois exemples, il s'agit d'illustrer les enjeux dans le domaine de la nanofabrication qui concernent à la fois le développement de matériaux nouveaux ainsi que la mise au point de procédés innovants adaptés permettant de répondre aux besoins constants de miniaturisation des systèmes.

The antisolvent performance and the results of cross-polarisation/magic angle spinning 13C nuclear magnetic resonance and Fourier transform infrared spectroscopy showed that the reaction of X-BR with KH560-modified SiO2 is a two-step process : X-BR is firstly adsorbed by KH560-modified SiO2 via van der Waals forces, and then nucleophilic substitution occurs between dichloro triazine and the epoxy group. The grafting ratio of X-BR on KH560-modified SiO2 reached 95% under optimum conditions, i.e. a mass ratio of KH560 to TEOS of 20%, a temperature of 40 °C, a pH of 8.5, and a reaction time of 5 h. X-ray diffraction analysis and transmission electron microscopy showed that the coloured nanoscale SiO2 was amorphous, with a mean diameter of 216 nm. Experimental application showed that the coloured nanoscale SiO2 had excellent stability to solvents and alkaline solution, and the absorptive capacity of the coloured nanoscale SiO2 in the 200–400 nm region was higher than that of X-BR. The light fastness of the coloured nanoscale SiO2 reached 5–6 grade. Note de contenu : - EXPERIMENTAL : Materials - Preparation of coloured nanoscale SiO2 - Printing - Characterisation

Their size ranges typically from 50 to 1000 nm. They differ from nanoemulsions in that the lipid core is a solid. The matrix consists of solid lipids or mixtures of lipids. Over the past years it has been demonstrated that solid lipid nanoparticles appear to be a promising drug carrier system for the future. Their occlusion properties reduce transepidermal water loss and can enhance penetration of active ingredients through the stratum corneum. As with all new technologies, some problems with the solid lipid nanoparticle technology need to be solved. One major problem is the homogeneous incorporation of amphiphilic active ingredients into the crystal matrix of the nanoparticles. Actives with an amphiphilic character like tocopherol or retinol cannot be kept homogeneously distributed in the wax structure during the emulsification process. Due to their hydrophilic head group they accumulate at the exterior layer of the nanoparticles together with the surfactant system used. Consequently, homogeneous release over time is not guaranteed and a burst release has to be expected. A second disadvantage is the manufacturing process. Solid lipid nanoparticles can be produced only under high pressure conditions. Also the concentration of the solid particles in the dispersion, which is added to an emulsion, is quite low. To overcome these problems membrane structured solid nanoparticles (MSSN) have been developed. These MSSN systems consist of liquid crystalline membrane systems with extremely low surfactant concentrations. The lateral movement of actives is controlled by amphiphilic solid actives such as ceramides and solid emollients. This guarantees maintenance of the advantageous properties of solid lipid nanoparticles such as retarded release of actives and their protection against chemical decomposition, but it also allows the homogeneous incorporation of amphiphilic actives. Membrane structured solid nanoparticles are produced using a continuous three-phase emulsification technique. This allows protection of heat-sensitive actives against decomposition. The concentration of nanoparticles in the MSSN dispersion can be kept higher than 60% (w/w). Even at these concentrations the nanodispersions keep their flow properties. As a result, they can be easily incorporated into the final formulation. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=10494

PolydiméthylsiloxaneLe polydiméthylsiloxane —[O-Si(CH3)2]n—, ou poly(diméthylsiloxane) selon la nomenclature systématique, communément appelé PDMS ou diméthicone, est un polymère organominéral de la famille des siloxanes souvent présent dans les shampoings. On l'y ajoute pour augmenter le volume des cheveux mais il peut également aller boucher les pores du cuir chevelu et rendre les cheveux gras. C'est une des raisons pour lesquelles se laver les cheveux tous les jours est très déconseillé avec un shampooing contenant des silicones.
Il existe également de l'amodiméthicone, qui est un dérivé du diméthicone.
Le polydiméthylsiloxane est un additif alimentaire (E900), utilisé comme antimoussant dans les boissons (Coca-Cola BlāK).
La chaîne de poly(diméthylsiloxane) forme également la structure de base des huiles et des caoutchoucs silicones.
Résistance à l'abrasionIndex. décimale : 667.9 Revêtements et enduits Résumé : The change in business trends for automotive coatings has started with the strategy of the car makers to concentrate on core competencies, followed by a strategy to outsource nonstrategic activities. Up till now Long term durability in terms of colour and gloss of coating has been mostly achieved nevertheless, a 10 years' warranty remains a target to be worked on by improving resin andadditive performances in optimized basecoat & clear coat formulae.
Maintenance-free coatings have been prevalent in the automotive market for some time. Customers are aware of the scratch problems caused by car wash. Furthermore, scratch-free cars have a higher attraction potential in dealer show rooms. Solutions are difficult to find owing to the fact that a coating has to pass a number of tests and has a broad spectrum of performances. One approach for improvement in this respect without detrimental effects on other properties is the evolution of new ideas based on nanotechnology.
This article reviews the method of improving mar resistance. Developing the product which meets the customer requirement with the use of Polymer technology, additive technology & most recent Nanotechnology.Note de contenu : - Method for testing mar resistance
