Observation, characterization and modeling of memristor current spikes (2013)
Journal Article

Memristors have been compared to neurons (usually specifically the synapses) since 1976 but no experimental evidence has been offered for support for this position. Here we highlight that memristors naturally form fast-response, highly reproducible a... Read More about Observation, characterization and modeling of memristor current spikes.

An investigation of volatile organic compounds from the saliva of healthy individuals using headspace-trap/GC-MS (2013)
Journal Article

Analysis of volatile organic compounds (VOCs) from saliva, to aid disease diagnoses, has received little attention. This work aims to address the paucity of information on saliva volatiles and includes a database of newly identified compounds whilst...

Autolysosomal β-catenin degradation regulates Wnt-autophagy-p62 crosstalk (2013)
Journal Article

The Wnt/β-catenin signalling and autophagy pathways each play important roles during development, adult tissue homeostasis and tumorigenesis. Here we identify the Wnt/β-catenin signalling pathway as a negative regulator of both basal and stress-induc...

A Pilot Study Combining a GC-Sensor Device with a Statistical Model for the Identification of Bladder Cancer from Urine Headspace (2013)
Journal Article

There is a need to reduce the number of cystoscopies on patients with haematuria. Presently there are no reliable biomarkers to screen for bladder cancer. In this paper, we evaluate a new simple in-house fabricated, GC-sensor device in the diagnosis...

Waste to real energy: The first MFC powered mobile phone (2013)
Journal Article

This communication reports for the first time the charging of a commercially available mobile phone, using Microbial Fuel Cells (MFCs) fed with real neat urine. The membrane-less MFCs were made out of ceramic material and employed plain carbon based... Read More about Waste to real energy: The first MFC powered mobile phone.

Underpotential deposition of lead at silver electrodes manufactured from compact discs and its determination in environmental water samples (2013)
Journal Article

The present paper describes the facile manufacture of silver electrodes from compact discs for the anodic stripping voltammetric determination of lead. The voltammetric behaviour of Pb in 0.1 M HCl was examined by cyclic voltammetry. Using a starting...

Analysis of the volatiles in the headspace above the plasmodium and sporangia of the slime mould (Physarum polycephalum) by SPME-GCMS
Journal Article

Solid phase micro-extraction (SPME) coupled with Gas Chromatography Mass Spectrometry (GC-MS) was used to extract and analyse the volatiles in the headspace above the plasmodial and sporulating stages of the slime mould Physarum Polycephalum. In tota... Read More about Analysis of the volatiles in the headspace above the plasmodium and sporangia of the slime mould (Physarum polycephalum) by SPME-GCMS.

An investigation into the fabrication of a new mini gas sensor for medical diagnostic applications (2013)
Thesis

This research was part of a larger Wellcome Trust funded project that aimed to create a non-invasive volatile diagnostic device for medical applications, particularly for the detection of Clostridium difficile (C. Diff) in human stool. The device (Od... Read More about An investigation into the fabrication of a new mini gas sensor for medical diagnostic applications.

Photosynthetic cathodes for microbial fuel cells (2013)
Presentation / Conference Contribution

One of the major limiting factors in the practical implementation of Microbial Fuel Cells is finding efficient and sustainable catalysts for the cathode half reaction, in an attempt to avoid expensive and/or toxic catalysts. The use of phototrophic o... Read More about Photosynthetic cathodes for microbial fuel cells.

The effect of air-drying on the volatiles composition of lemon thyme (Thymus citriodorus) and lemon verbena (Aloysia triphylla) (2013)
Journal Article

The research investigates the effect of air-drying on the volatile composition of infusions prepared from Thymus citriodorus (Pers.) Schreb and lemon verbena (Aloysia triphylla (L'Herit)). The fresh and the dried herbs were analysed over a period o...

Hydrogen sulfide: Environmental factor or signalling molecule? (2013)
Journal Article

Hydrogen sulfide (H2S) has traditionally been thought of as a phytotoxin, having deleterious effects on the plant growth and survival. It is now recognized that plants have enzymes which generate H2S, cysteine desulfhydrase, and remove it, O-acetylse... Read More about Hydrogen sulfide: Environmental factor or signalling molecule?.
