Simplified tunnelling current calculation for MOS structures with ultra-thin oxides for conductive atomic force microscopy investigations (2005)
Journal Article

As charge tunnelling through thin and ultra-thin silicon dioxide layers is regarded as the driving force for MOS device degradation the determination and characterisation of electrically week spots is of paramount importance for device reliability an...

The formation of voronoi diagrams in chemical and physical systems: Experimental findings and theoretical models (2004)
Journal Article

The work discusses the formation of Voronoi diagrams in spatially extended nonlinear systems taking experimental and theoretical results into account. Concerning experimental systems a number of chemical systems used previously as prototype chemical...

Experimental implementation of mobile robot taxis with onboard Belousov-Zhabotinsky chemical medium (2004)
Journal Article

We discuss the first-ever experimental realization of the onboard excitable chemical controller for stimulus-guided navigation of mobile robots. We demonstrate that the Belousov-Zhabotinsky (BZ) reaction in the form of an onboard thin layer chemical...

Identification by gas chromatography-mass spectrometry of the volatile organic compounds emitted from the wood-rotting fungi Serpula lacrymans and Coniophora puteana, and from Pinus sylvestris timber (2004)
Journal Article

Volatile organic compounds (VOCs) emitted by two wood-rotting basidiomycete fungi, Serpula lacrymans (dry rot fungus) and Coniophora puteana (cellar fungus), and the timber of Pinus sylvestris (Scots pine), were identified. Several volatile collectio...

Use of External Magnetic Fields to Reduce Reaction Times in an Immunoassay Using Micrometer-Sized Paramagnetic Particles as Labels (Magnetoimmunoassay) (2004)
Journal Article

The paper presents a rapid immunoassay system capable of quantifying analyte in complex biological and environmental media. Antibody-coated micrometer-sized paramagnetic particles are used as labels in an assay in which they bind quantitatively with...

A novel method for rapidly diagnosing the causes of diarrhoea (2004)
Journal Article

Background: The microbiological diagnosis of infectious diarrhoea may take several days using conventional techniques. In order to determine whether flatus can be used to make a rapid diagnosis, the volatile organic compounds associated with diarrhoe...

Topology: A novel method to describe branching patterns in Peronospora viciae colonies (2003)
Journal Article

Topology provides a novel means to describe branching patterns and has not been applied to fungal colonies previously. For any branched structure, various topologies are possible, and these lie between two extremes, a herringbone pattern (main axis w...

The synthesis of novel 3-substituted pyrrole monomers possessing chiral side groups: A study of their chemical polymerisation and the assessment of their chiral discrimination properties (2003)
Journal Article

Novel 3-substituted pyrrole monomers possessing chiral side groups were synthesised. These compounds were successfully polymerised with ferric salts and the polymer materials fabricated into sensors. The sensors were found to elicit differential chan...

Experimental reaction-diffusion chemical processors for robot path planning (2003)
Journal Article

In this paper we discuss the experimental implementation of a chemical reaction-diffusion processor for robot motion planning in terms of finding the shortest collision-free path for a robot moving in an arena with obstacles. These reaction-diffusion... Read More about Experimental reaction-diffusion chemical processors for robot path planning.

Rapid and direct determination of tryptophan in water using synchronous fluorescence spectroscopy (2003)
Journal Article

Water samples from lakes situated in and around the area of Tsukuba Science City, Ibaraki Prefecture, Japan, were analysed using synchronous fluorescence spectroscopy and HPLC. The spectra revealed a major emission peak (λemm) at 340nm corresponding... Read More about Rapid and direct determination of tryptophan in water using synchronous fluorescence spectroscopy.

Thick film organic vapour sensors based on binary mixtures of metal oxides (2003)
Journal Article

Previously, composite sensors incorporating differing proportions of tin dioxide and zinc oxide were reported which exhibited high sensitivity to a range of organic vapours under dry conditions (0% relative humidity, RH). Most importantly, the compos... Read More about Thick film organic vapour sensors based on binary mixtures of metal oxides.

A prototype sensor system for the early detection of microbially linked spoilage in stored wheat grain (2003)
Journal Article

Spencer-Phillips was Co-Investigator, the lead biologist in this HGCA-funded multi-disciplinary work, and co-wrote the paper. The grant was based on his expertise in the microbiology of post-harvest spoilage.

Syntheses and polymerizations of (E)-2-styrylfurans and an investigation of their electrorheological properties (2003)
Journal Article

Novel furan compounds, which incorporate phenyl rings separated by alkene spacers, have been synthesized. Chemical polymerization of these compounds yielded black brittle powders, suspensions of which were found to exhibit significant electrorheologi...
