Abstract:
A method of characterizing materials comprising the steps of: providing a substrate; synthesizing an array of materials on said substrate; providing at least one reactant gas wherein said reactant gas is in contact with said array of materials; activating at least one of said materials on said array with a heating source; and periodically monitoring an infrared emission from said activated material with an infrared camera, wherein said infrared camera outputs a series of signals corresponding to an emission intensity varying with time of said activated material.
Abstract:
Methodologies for the synthesis, screening and characterisation of organometallic compounds and catalysts (eg homogenous catalysts), including combinatorial synthesis, screening and characterisation of libraries of supported and unsupported organometallic compounds and catalysts (eg homogenous catalysts). The methods can be applied to the preparation and screening of large numbers of organometallic compounds which can be used not only as catalysts (eg homogeneous catalysts), but also as additives and therapeutic agents.
Abstract:
Methods and apparatus for screening diverse arrays of materialsa nd for imaging a library of materials are provided using ultrasonic imaging techniques. Systems include tranducer lens (109) or mechanical resonator for exiting an element of library deposited onto a substrate (103) such that acoustic waves are propagated through, and from, the library element (101). The acoustic waves propagated from the element are detected and processed to yield a visual image of the library element; such acoustic wave data is processed to obtain information about various properties of the library elements (e.g. elasticity, molecular weight, viscosity, specific weight, dielectric properties, conductivity, etc.) of individual liquid elements. Acoustic waves are generated in an imaging tank filled with coupling liquid (107), with the library of materials then placed in the tank while the surface of the coupling liquid is scanned with a laser beam. The physical structure of the liquid surface distubed by these acoustic waves is recorded.
