Summary on Grant Application Form
The proposed research will extend characterisation capabilities in high throughput investigations in various areas including materials, formulations and catalysis. Core research will be conducted in technologies that will permit the combination of in-situ physical property characterisation and molecular spectral measurements, with discriminating multivariate data analysis procedures. The research focuses on developments in acoustic spectrometry and optoelectronics for mid-infrared (MIR) spectrometry. The ultimate aim is to develop compact, low cost HT modules based on non-invasive acoustic measurements and miniaturised MIR systems. In the acoustic area, the emphasis will be on improving the understanding and analysis of backscattered acoustic signals for physical property characterisation. The research will allow development of a new range of ultra wideband ultrasonic transducers that will be used with pseudorandom coding sequences for improved quantification of ultrasonic backscatter. Potential applications include HT studies of catalysts, suspensions, heterogeneous processes leg. crystallisation) and polymers. The aim of the optoelectronic part of the research programme is the development of a new generation of narrowband sources for chemical characterisation by mid-infrared spectrometry. These sources will be based on lead chalcogenide semiconductors and III-V semiconductor alloys containing antimony. A series of wafer structures will be designed and grown. These structures will then be built into laser sources which, in the long term, could be electrically excited leading to a range of low cost, compact narrowband sources, designed to emit at specific wavelengths appropriate to the needs of particular studies. These sources will be used in absorption and reflection modes, in conjunction with wavelength specific detectors within the HT module, avoiding the need for extensive lengths of MIR transmitting fibres. Associated research will devise improved multivariate chemometric methods for smart data searching, data processing and calibrationless analysis.
