Polyméthacrylate de méthyleLe poly(méthacrylate de méthyle) (souvent abrégé en PMMA, de l'anglais Poly(methyl methacrylate)) est un polymère thermoplastique transparent obtenu par polyaddition dont le monomère est le méthacrylate de méthyle (MMA). Ce polymère est plus connu sous son premier nom commercial de Plexiglas (nom déposé), même si le leader global du PMMA est Altuglas International9 du groupe Arkema, sous le nom commercial Altuglas. Il est également vendu sous les noms commerciaux Lucite, Crystalite, Perspex ou Nudec.

VitrageIndex. décimale : 668.4 Plastiques, vinyles Résumé : A market (or platic) on the move. After the turbulent times of recent years, in which the PMMA market suffered a severe drop in demand in 2009 due to the recession, followed by a powerful opturn in 2010 and 2011 with considerable delivery problems - driven mainly by the demand for light-guide panels in LED TVs - the market stabilized to a great extent in 2012. In spite of negative economic forecasts due to the European debt crisis, which mainly hit the automotive industry and the construction business, and new substituing technologies in the electronics indsutry, the established material PMMA continues to re-invent itself in attractive applications.

Les matériaux électroluminescents utilisés dans les OLED sont constitués de molécules ou de polymères Ï€-conjugués dont la couleur d’émission peut être choisie par ingénierie chimique. Les OLED sont d’ores et déjà utilisées dans les écrans de visualisation et le seront prochainement comme source d’éclairage basse consommation. Note de contenu : - Les OLED ou LED du chimiste

To this end, seven achromatic physical scales of specular gloss each consisting of 10 or 11 samples were prepared using lithographically printed black, white, and five in between gray papers. The samples were visually assessed and subsequently quantified in terms of a visually uniform color constant lightness scale, by a panel of 14 observers in an especially designed unidirectional light compartment at three illumination/observation geometries, namely 20°/20°, 60°/60°, and 85°/85°. Four statistical parameters were utilized to determine the correlation between visually perceived and instrumentally measured specular gloss. The results show that the instrumental 60°/60° geometry is capable of efficiently quantifying the equivalent specular gloss as perceived by a human observer. Surprisingly, it was also possible to accurately predict the visually quantified specular gloss both at the 20° and the 85° geometries by the aid of applying special linear relationships derived from the instrumentally measured specular gloss of the 60° geometry.

Revêtements décoratifsIndex. décimale : 667.9 Revêtements et enduits Résumé : Solid-state lighting in the form of light emitting diode lamps is quickly taking over the world as replacements for existing lower efficiency lamps. The lighting standards, which phased in from 2012 to 2014, do not ban incandescent or any specific lamp type, but they do require that lamps need to use about 25% less energy. The bipartisan Energy Independence and Security Act of 2007 (EISA 2007) established these efficiency standards. Many commercial lamps meet these new standards, including halogen incandescent filament, CFLs, and LEDs. The new bulbs provide a wide range of choices in color and brightness, and many of them last much longer than traditional lamps. However, the spectral distribution of flux from some of these new lamps do not match or even correspond to the spectral power distribution of traditional office and home lighting. In this review, the impact of the new lamp lights on the design, marketing, and production of modern decorative coatings is assessed. The decorative coatings industry has followed recommended guidelines for many decades, producing color-matches that are acceptable under a series of standard illuminants (D65, CWF, A) which are representative of the lamp lights in most common facilities. The new solid-state lamps do not render object colors in ways similar to the currently adopted standardized illuminants. The primary obstacle to the coatings manufacturer is the lack of standards on how to test color-matches for quality conformance under the new lamp lights. As the energy efficient lighting industry is currently still in a technologically developing phase, it appears that it will be some time before any agreements on the characteristics of modern lamp light will be reached. Therefore, guidance is provided on creating and/or using illuminant data representative of these lamps until official reference illuminants are published.

Lumière artificielle -- Effets physiologiquesIndex. décimale : 535 Lumière visible Résumé : This paper reviews current knowledge on non-image-forming aspects of vision. Developments in the last 20 years have included the discovery of a fifth class of human visual pigment (melanopsin), in addition to the three classes of photopsin to be found in the cones and rhodopsin in the rods in the human retina. Melanopsin is found in a small number of retinal ganglion cells which then, in addition to receiving input from rods and cones, are intrinsically photosensitive. These retinal ganglion cells send their input primarily to the hypothalamus, where they help to regulate the circadian system (daily rhythms of sleep patterns, body temperature, heart rate, etc.). The discovery of the anatomical basis of non-image-forming vision has led to a great deal of research into the effects of light on sleep, depression and mood, retinal photodamage and well-being, amongst other factors. Given that recent technological innovations in LED lighting now give us greater control over environmental lighting, it is timely to review the non-visual effects of light in humans in order to inform lighting design in the future.
