CODEN: JKXXAF. CLASS: ICM: G06K019-077.Some commonly used reagents like 2551-83-9 and 2530-85-0 are used in this experiment. ICS: B42D015-10; C09J133-00; C09J163-00; C09J175-04; C09J201-02. APPLICATION: JP 2002-185720 26 Jun 2002. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) The laminated structure with reduced stress is derived by placing an IC unit in between two pieces of sheet materials and bonding the sheet materials using an adhesive contg. alkenyl-bearing hydrocarbon polymers with mol. wt. 500-30 x 104, hardeners, and hardening catalysts. Prepg. a catalysts soln. contg. Diana Process oil 100, 50% methanolic Al acetylacetonate 2, and Pt-divinyltetramethyldiloxane complex 0.3 part and adding (15 parts) to a base soln. (300 parts) contg. Epion EP 600A 100, Diana Process PW 380 100, Sealets 300 100, Whiton SB 100, Talc LMR 50, and Et Silicate 28 1.5 part gave a first liq. Adding CR 300 100, KBM 403 10, KBM 503 10, and allyltrimethoxysilane 5 parts to the same base soln. gave a second liq. The two liqs. were mixed at 1:1 ratio and used to bond two PET film contg. an IC unit therein, showing good adhesion. .

Three-dimensional colloidal crystals with a well-defined architecture

Three-dimensional colloidal crystals with a well-defined architecture. Reculusa, Stephane; Masse, Pascal; Ravaine, Serge (CNRS, Centre de Recherche Paul Pascal, Pessac 33600, Fr.). Journal of Colloid and Interface Science, 279(2), 471-478 (English) 2004 Elsevier. CODEN: JCISA5. ISSN: 0021-9797. DOCUMENT TYPE: Journal CA Section: 66 (Surface Chemistry and Colloids) Monodisperse silica spheres with diams. of 220-1100 nm were prepd. by hydrolysis of tetra-Et orthosilicate (TEOS) in an alc. medium in the presence of water and ammonia. By grafting vinyl or amino groups onto silica surfaces using the coupling agents allyltrimethoxysilane and aminopropyltriethoxysilane, resp., amphiphilic silica spheres were obtained and could be organized to form a stable Langmuir film at the air-water interface. The controlled transfer of this monolayer of particles onto a solid substrate gave us the ability to build three-dimensional regular crystals with a well-defined thickness and organization. These colloidal crystals diffract light in the UV, the visible, and the near-IR (NIR) spectral regions, depending on the size of the silica spheres and according to Bragg's law. The depth of the photonic stop band can be tuned by varying the no. of deposited layers of particles. By using successive depositions, we could prep. multilayered films with silica spheres of different sizes. The thickness of each slab in the binary crystals can be tuned at the layer level, while the cryst. order of each layer is well preserved.Except for chemicals metioned above, 7631-86-9 and 2551-83-9 are also used. .
