Sol-gel, ProcédéIndex. décimale : 667.9 Revêtements et enduits Résumé : Cation-exchanged montmorillonite (MMT), which is an aluminum-pillared clay, was dispersed into an organic–inorganic hybrid silica matrix sol. Cationic inhibitors Ce3+/Zr4+ were introduced into montmorillonite by two methods, namely (1) physical mixing of MMT with the inhibitor solutions and (2) physical mixing for short durations and evacuation of the mixture of MMT and inhibitor solutions. Coatings using these sols were deposited on aluminum alloy AA 2024-T4 substrates, by the dip coating technique followed by thermal curing at 130°C for 1 h. TEM, BET, and XRD analyses were carried out for the inhibitor-modified montmorillonite powders. Potentiodynamic polarization and electrochemical impedance spectroscopic analyses were carried out on uncoated and coated substrates to evaluate the corrosion protection property after exposure to 3.5 wt% NaCl for varying time durations, up to 120 h. Self-healing ability was evaluated using SVET analysis by creating an artificial scribe on the surface and exposure to 3.5 wt% NaCl. Elemental mapping was carried out on scribed substrates before and after exposure to 5 wt% salt fog. Sols containing montmorillonite intercalated with cationic inhibitors when deposited on AA 2024-T4 substrates exhibited low corrosion currents after a prolonged duration of exposure to corrosion medium.

VieillissementIndex. décimale : 668.5 Parfums et cosmétiques Résumé : So, altogether a number of claims for the nails can be objectively measured. The effect of nail hardeners, nail polish and the properties of various types of artificial nails can be easily demonstrated with the new Nail StrainStress Meter. Other claims could be restructuringand re-densifying of the nails by certain food supplements.
Projective products could be evaluated by measuring the evaporation rate of the water. Also, the TOWL measurement could be used to show that nail polish remover, the glue from an artificial nail or other aesthetic nail treatments do not damagethe nail.
Fields of application for the assessment of nail gloss and colour are obvious, and not only restricted to the evaluation of applied nail polish. Such measurement can also be used to show the effects of withening products and mechanical polish.
Even in medical conditions like nail fungus, the measurement of nail thickness could give an indication of the effect of treatment with anti-fungal medication. As also other skin diseases can extend to the nails, the oblective measurement of the nail condition can be used to offer additionalinformation about the overall improvement by medical treatment.
And why not try to test whether my anti-ageing hand cream does not also improve the condition of my fingernails? There are no limits to new claims created around nail care that can be proven with these new methods.Note de contenu : - Structural strengh/firmness

Contrôle par courants de FoucaultLa technique de contrôle par courants de Foucault est une méthode de Contrôle Non Destructif (CND) fondée sur la circulation de courants induits dans un matériau conducteur. En anglais, cette technique est dénommée Eddy current Testing (ET). La configuration de contrôle la plus simple consiste à utiliser un bobinage alimenté par une tension sinusoïdale. Ce bobinage est placé à proximité de la pièce à contrôler. Le bobinage crée un champ magnétique sinusoïdal dans la pièce. Des courants apparaissent dans la pièce et s'opposent à la variation du champ magnétique (Loi de Lenz-Faraday).

Ondes électromagnétiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Car paintwork has to withstand a wide range of stresses and therefore at least four different coats are generally applied to vehicle bodies. Until now there has been no non-destructive method of measuring the thickness of these multi-layer coatings on metal or plastic, but terahertz technology will soon change that. Note de contenu : - Operation
- Comparing terahertz technology
- Other applications
- Fig. 1 : The terahertz pulse penetrates the plastic coating and is partially reflected at the material boundaries. The software calculates the thickness of each layer on the basis of the delay time of the reflections
- Fig. 2 : Terahertz technology will make quality assurance processes noticeably more efficient, in particular in the automotive industry
- Fig. 3 : When measuring a wedge cut, terahertz technology compares favourably with established methods, such as microscopy and magnetic inductionPermalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=30420
