    Personal profile

    General

    Dr Doudin is an organic chemist who joined the school of Chemical Engineering and Applied Chemistry at Aston University in May 2004. He started with us as a research fellow for few years then as Nuclear Magnetic Resonance (NMR) and Characterisation Specialist and Undergraduate Projects Officer.

    His research involves analysis and characterisation of organic materials, using a variety of spectroscopic and thermal methodologies, very often with the aid of different chromatographic techniques. Most of his research has been focused on the performance of natural additives (such as, Vitamin E, Rosemary extracts, Caffeic acid derivatives …) in stabilising polymers and bio-oils.

    A number of collaborations both within Aston and externally started. Being an NMR specialist with extensive knowledge of other characterisation techniques working with different groups has allowed Dr Doudin to add an extra dimension to the school research.

    Research Projects/Collaborations

    • A project on the oxidation and stability of vegetable oils on kitchen metal surfaces, my work was mainly focused on characterisation and understating retarding the polymerisation of unsaturated hydrocarbon moieties of the oils and the influence of stabilisers (antioxidants) on limiting the influence on metals surfaces on the oil polymerisation / toughening process.

    • In another project I have worked on in the use of natural antioxidants extracted from rosemary (polyphenols) in oils and polyolefins industries, in collaboration with Boots, Croda, Lubrizol and others. The targeted antioxidants were chemically modified to suite the different industries, characterised and their effectiveness was tested in the different systems.

    • I have worked on a project on the stabilisation of medical implants (Tibias) made of Polyethylene (UHMWPE) by Vitamin E. What is happening to the Vitamin E during the making process of medical implants was the focus of the projects. The formed products were extracted, separated, characterised, quantified and identified.

    • One project involves the NMR characterisation of reactive (graftable) functional groups on polyethylene and ethylene propylene rubber.

    • A collaborative project on new approach to prepare phase change microcapsules using carbon-based particles via Pickering emulsions for energy storage applications

    • With Prof. K W Törnroos, University of Bergen, Norway, worked on completing unfinished work for my PhD study.

    K. Doudin, K.W. Törnroos, Selenium carboxylic acids betaine; 3,3′,3″- selenotris(propanoic acid) betaine, Journal of Molecular Structure 1137 (2017) 506- 511.

    • On a project with School of Pharmacy, University of Wolverhampton worked on the effect of polymers on the release drug from tablets, drug-polymers chemical interactions were studied using spectroscopic and differential scanning calorimetry analysis.
