Simulation of the Cyclic Voltammetric Response of an Outer-Sphere Redox Species with Inclusion of Electrical Double Layer Structure and Ohmic Potential Drop

Autor: Katie Levey, Martin Edwards, Henry White, Julie Macpherson

A finite-element model has been developed to simulate the cyclic voltammetric (CV) response of a planar electrode for a 1e outer-sphere redox process, which fully accounts for cell electrostatics, including ohmic potential drop, ion migration, and th

Electron Paramagnetic Resonance for the Detection of Electrochemically Generated Hydroxyl Radicals: Issues Associated with Electrochemical Oxidation of the Spin Trap

Autor: Emily Braxton, David Fox, Ben Breeze, Joshua Tully, Katherine Levey, Mark Newton, Julie Macpherson

For the detection of electrochemically produced hydroxyl radicals (OH˙) from the oxidation of water, electron paramagnetic resonance spectroscopy (EPR) in combination with spin trap labels is a popular technique. Here we show that quantification of

Electron Beam Transparent Boron Doped Diamond Electrodes for Combined Electrochemistry – Transmission Electron Microscopy

Autor: Haytham Hussein, Georgia Wood, Daniel Houghton, Marc Walker, Yisong Han, Pei Zhao, Richard Beanland, Julie Macpherson

The majority of carbon based transmission electron microscopy (TEM) platforms (grids) have a significant sp2 carbon component. Here, we report a top down fabrication technique for producing freestanding, robust, electron beam transparent and conducti

Finite Element Modelling of the Combined Faradaic and Electrostatic Contributions to the Voltammetric Response of Monolayer Redox Films

Autor: Katherine Levey, Martin Edwards, Henry White, Julie Macpherson

The voltammetric response of electrodes coated with a redox-active monolayer is computed by finite element simulations based on a generalized model that couples the Butler-Volmer, Nernst-Planck and Poisson equations. The model yields a full descripti

A Versatile DIY Route for Incorporation of a Wide Range of Electrode Materials into Rotating Ring Disk Electrodes

Autor: Joshua Tully, Zhaoyan Zhang, Irina Terrero Rodríguez, Lee Butcher, Julie Macpherson

Rotating ring disk electrodes (RRDEs) are a powerful and versatile tool for mechanistically investigating electrochemical reactions at electrode surfaces, particularly in the area of electroanalysis and catalysis. Despite their importance only limite

Diamond Membrane Production: The Critical Role of Radicals in the Non-Contact Electrochemical Etching of sp2 Carbon

Autor: Josh Tully, Emily Braxton, Sam Cobb, Ben Breeze, Matthew Markham, Mark Newton, Paramaconi Rodriguez, Julie Macpherson

Sub-micrometre single crystal diamond membranes are of huge importance for next generation optical, quantum and electronic device applications. Electrochemical etching has proven a critical step in the production of such membranes. Etching is used to

Lifting the Lid on the Potentiostat: A Beginners Guide to Understanding Electrochemical Circuitry and Practical Operation

Autor: Alex Colburn, Katharine Levey, Danny O'Hare, Julie Macpherson

Students who undertake practical electrochemistry experiments for the first time, will come face to face with the potentiostat. To many this is simply a box containing electronics which enables a potential to be applied between a working and referenc

Ex-vivo Electrochemical pH Mapping of the Gastrointestinal Tract in the Absence and Presence of Pharmacological Agents

Autor: Julie Macpherson, Bhavik Patel, Aya Abdalla, Tania Read, Teena Rajan

Ex-vivo pH profiling of the upper gastrointestinal (GI) tract (of a mouse) in both the absence and presence of pharmacological agents aimed at altering acid/bicarbonate production, is reported using an electrochemical pH probe, for the first time. Th

Assessment of Acid and Thermal Oxidation Treatments for Removing Sp2 Bonded Carbon from the Surface of Boron Doped Diamond

Autor: Sam Cobb, Fraser Laidlaw, Geoff West, Georgia Wood, Mark Newton, Richard Beanland, Julie Macpherson

The presence of sp2 bonded carbon on a diamond or doped diamond surface, as a result of growth or processing, can affect material properties negatively, hence removal processes must be developed. Using boron doped diamond (BDD) we investigate the eff
