    Research interests

    G. Peter Matthews is Professor in Applied Physical Chemistry in the School of Earth, Ocean and Environmental Sciences at the University of Plymouth.  He is also CEO and director of PoreXpert Ltd, the university’s main spin-out company, selling consultancy services and the PoreXpert suite of software described below.

    Matthews studied chemistry at Oxford University, gaining a distinction in chemical pharmacology, and going on to be awarded a doctorate there for research into the measurement and computer modelling of the flow of simple gases.  Subsequently he supervised and developed Oxford’s physical chemistry teaching laboratories while a college lecturer at St Catherine’s College, before moving to Plymouth in 1985.  He has maintained an interest in teaching, having been HEFCE national assessor for Chemistry and Environmental Science, developing these courses at Plymouth, and acting as chair for numerous other course validations.  

    His Environmental and Fluid Modelling research interests are currently concerned with fluid flow in porous materials, particularly when this has environmental importance.  His research group currently comprises an industrially sponsored research lecturer, two PhD students, and one internal and three external post-doctoral fellows. He has previously supervised 20 PhDs, 17 as P.I., to successful and timely completion.  He has attracted £4.8m of research funding to date, the sources of which have been research councils (NERC Environmental Diagnostics programme, NERC NE/K004212/1, EPSRC GR/K70489 and BBSRC BB/E001793/1, BB/E001793/1), industry (British Gas / Transco, Omya AG, EDF), and purchasers of the software described below.  He has written 152 publications in research and pedagogy, including a 500 page textbook on Experimental Physical Chemistry (Oxford University Press, 1985), and over 35 consultancy reports.  

    Matthews’ research group has pioneered a new way of modelling porous materials, by producing software (Pore-Cor succeeded by PoreXpert® ) which generates three-dimensional void networks which closely match the full percolation characteristic and porosity of any meso- and macro-porous material.  Matthews’ approach contrasts with the otherwise almost universal approach which is simply to take the slope (1st derivative) of the percolation characteristic, in the form of a mercury porosimetry intrusion curve or a soil water retention curve, and equate it to the number of voids of that size.  However the traditional approach is only valid for the very small number of samples, such as track-etch membranes, which comprise aligned capillary tubes which do not connect with one another.  In the new approach, the simulated structures are generated by means of Euler beta and gamma functions optimised by a Boltzmann-annealed amoeboid simplex.  The simplex not only fits the entire percolation characteristic and porosity, but also builds in other characteristics, such as short range size auto-correlation functions, in a Bayesian type of approach (Matthews et al., 2006).  Once the structure has been generated, a wide range of characteristics and properties of the void network can be examined, such as the absolute sizes and numbers of voids, connectivity of the network, absolute permeability, diffusion, tortuosity, thermal conductivity and filtration characteristics (Gribble et al., 2011). A patented module within PoreXpert can be used to optimize the design of porous materials, or predict properties such as ageing and formation damage.

    To a first approximation, the behaviour of fluids within pores is dependant only on the cross-sectional sizes of the voids, their volumes, the interfacial tension of the fluid system, and, in the case of liquids, the contact angle at the surface of the solid.  Therefore there is considerable symbiosis between studies on widely different materials in different research areas, and many of these systems have direct or indirect environmental importance.   

    Of particular importance are dual porous systems – i.e. solids comprised of particles, between which is inter-particle porosity, and in which the particles themselves have intra-particle porosity (Laudone et al 2013). Examples of this are soil, where for example nitrifying bacteria reside in the intra-particle porosity (Laudone et al. 2011), and high performance modified-calcium-carbonate (MCC) paper coatings, for which the dual porosity gives very fast and accurate ink adsorption properties (Ridgway et al. 2011).  Gilsocarbon graphite, used in the cores of AGRs at six sites in the UK, also has a highly complicated pore structure, comprising an openly accessible void network, a void network accessible at moderate pressure, and closed porosity deriving from air bubbles in the original graphite / pitch mix before baking (Laudone et al. 2014). 

    Pore-Cor and PoreXpert straddle the continuum threshold – i.e. the sample size at which individual pore level effects can be integrated and upscaled to core and field scale – an approach now being used to upscale soil hydrophobicity transitions to a scale which can be incorporated into the Met Office JULES climate-change dependant hydrological model (NE/K004212/1).

    From January to April 2007, Matthews was Royal Society visiting associate professor in the Department of Applied Mathematics, in the Research School of Physical Science and Engineering at the Australian National University, Canberra.  He was associate editor of the European Journal of Soil Science in 2012-2104, and was founding editor of InterPore News, the newsletter of the international society for porous material research.  In September 2012 he and his team won the Vice Chancellor’s Enterprise Award for expertise in applied research.  Also in September 2012, the university gained a National Enterprise Educator Award, with a significant element being his incorporation of the Flux business challenge into the chemistry course.  In June 2012, Matthews’ laboratories were one of three at the university that together were awarded the competitive national S-lab Award, (S = Safe, Successful and Sustainable).  In 2010-13 he was advisor to the Dean of the Faculty of Science on staff resourcing issues, on the basis of his development of the Faculty Resource Model which cross-correlates teaching activity, research activity and financial income from students.

    Other academic activities

    Consultancy

    The Environmental and Fluid Modelling Group laboratories, located in Davy Building 601 and 602, provide consultancy services for the characterisation of porous solids. 

    Equipment includes a Thermo Fisher mercury porosimeterhelium and powder/envelope pycnometers, Kruss picolitre goniometer , and Bel Nippon analyser for low surface area samples. 

    The laboratory achieved full ISO 9001:2008 accreditation in August 2010, and all mercury porosimetry work is already done according to strict protocols which exceed those required by the instrument manufacturer. 

    Additional information

    Peter Matthews takes a paternal delight in the achievements of his family, and the business, medical, scientific and engineering interests of his children.

    With his wife Diane as main carer, Peter has extensive experience in the rehabilitation of babies and children following abuse, neglect or abandonment.  The efforts of Peter and his wife were recognised in a prize and citation presented by Pirate FM, on behalf of Cornwall County Council Children's Services, at a celebration evening in Newquay in October 2008.

    Peter also sings first bass in the East Cornwall Bach Choir.

    He is a keen photographer, with several photos published by local media, and has raised beef and dairy cattle, sheep and ponies in his SPS registered 0.9 hectare field.
