20130288035 | Manufacture of Composite Optical Materials - A polymer opal material comprises a three dimensionally periodic arrangement of core particles in a matrix material and exhibits structural colour via Bragg reflection. IN a process for manufacturing such a material, a sandwich structure is provided, of a precursor composite material held between first and second sandwiching layers.

20150109657 | Composite Optical Materials for Mechanical Deformation - A composite optical device has a layer of a composite optical material mounted on a substrate. The layer of composite optical material has substantially uniform thickness. The composite optical material is a polymer opal, in that it has a three dimensional arrangement of core particles distributed in a matrix, the refractive index of the material of the core particles being different to the refractive index of the material of the matrix and the three dimensional arrangement being capable of having a periodicity such that, when a surface of the material is illuminated with white light, the composite material exhibits structural colour. The local stiffness of the substrate is different at different positions of the substrate. The effect of this is that, on mechanical deformation of the composite optical device, the substrate is deformed to a different extent at different positions of the substrate and the layer of composite optical material is correspondingly deformed to a different extent at different positions of the layer of composite optical material. This provides local variation in the structural colour response of the layer of composite optical material on mechanical deformation of the composite optical device. | 04-23-2015 |

20120161431 | METHOD OF FORMING A PHOTONIC CRYSTAL MATERIAL - A method of forming a film of photonic crystal material. A first process is performed upon a material capable of having a photonic crystal structure, this process causing deformation of the material so as to form a film in which incident light received by the material is selectively reflected or transmitted to generate a first optical effect in the film. A second process is performed upon substantially all of the film which applies a shear stress to the film. This causes a change in the material structure so as to generate a second optical effect in the film, different from the first optical effect, in response to incident light. Security films, devices, articles and documents formed using the method are also discussed. | 06-28-2012 |

20090221860 | TRANSPORT OF ETHYNE IN FORM OF A-ALKYNOLS AS ETHYNE PRECURSORS - The present invention relates to a new method for a safe transport of ethyne in form of α-alkynols as precursors for ethyne. The new method comprises three steps. In a first step the synthesis of the α-alkynol(s) is performed by reacting ethyne with (a) carbonyl compound(s). The second step comprises the transport of the resulting α-alkynol(s) in a safe manner, whereas the safety requirements for this transport are not as high as for ethyne because α-alkynol(s) are normally classified for transportation as hazardous class 3. In the third step the α-alkynol(s) can be cleaved and the ethyne and the carbonyl compound(s) can be obtained in the cleavage reaction and can be separated to yield pure products for further applications. | 09-03-2009 |
