Titre : Functionalisation of lyocell. Part 2 : Synthesis of 6-p-aminoanilino-4-p- (B-sulphatoethylsulphonyl)anilino- 1,3,5-triazin-2(1H)-one Type de document : texte imprimé Auteurs : A. H. M. Renfrew, Auteur ; I. Bates, Auteur ; Duncan A. S. Phillips, Auteur ; T. Rosenau, Auteur ; T. Tomic, Auteur ; J. Xu, Auteur Année de publication : 2009 Article en page(s) : p. 56-61 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : A new water-soluble monomeric agent for the aminisation of lyocell has been designed and synthesised. The agent, which contains a sulphatoethylsulphonyl group, an s-triazinyl keto–enol tautomeric system and a primary aromatic amine was prepared in acidic media, in good yield from cyanuric chloride, p-aminophenyl-b-sulphatoethylsulphone and p-phenylenediamine, via a triazinyl betaine intermediate.

They provide the cut-off free volumes to absorb and transfer gas molecules. The corresponding sorption and diffusion properties were determined via Grand Canonical Monte Carlo (GCMC), NVT-Molecular Dynamics (MD) and cluster analysis methods. The results showed that temperature and pressure influence the sorption properties of gases obviously, but not to the diffusion coefficients of gases. Analyzing on the mean square displacement (MSD) data, this work finds that gases walk randomly through amorphous PPX polymers. The relative cluster permeability approaches to the experimental data.

Titre : Study of infrared thermal images of chameleon - type building coatings Type de document : texte imprimé Auteurs : Yiping Ma, Auteur ; J. Xu, Auteur ; Beirong Zhu, Auteur ; Keru WU, Auteur Année de publication : 2003 Article en page(s) : p. 43-47 Note générale : Bibliogr. Langues : Américain (ame) Tags : Bâtiment Absorption énergie Propriété surface Formulation Pigment Thermométrie IR Thermochromisme Matériau revêtement Index. décimale : 667.9 Revêtements et enduits Résumé : As reported in this article, infrared thermal images of chameleon-type building coatings were studied. The results show that when reversibly thermochromic pigments were added to normal white building coatings, so-called chaemelon-type building coatings could absorb energy from a sunlamp below a switching temperature of 20°C. The surface temperatures could reach almost the same value as that of a normal colorful building coating. The absorption stopped automatically above the switching temperature of 20°C, and the surface temperatures could be lower than that of normal colorful building coatings by about 4°C. The results from exposure to solar radiation show that when the temperature was below the switching temperature, the chameleon-type building coating could absorb almost the same amount of solar energy as an ordinary colorful coating. When the temperature was above the switching temperature, these coating could reflect more solar energy than the ordinary colorful coating, which was similar to the results from infrared thermal images. All the results show that there is some posibility that the chameleon-type building coatings could be used to create a thermally comfortable building environment.
