Journal ArticleDOI
The modification of enzyme electrode properties with non-conducting electropolymerised films
TL;DR: Phenol and several phenol derivatives have been electropolymerised on to platinum anodes and the selective properties of the modified electrodes were dependent on the final polymeric structure as discussed by the authors.
Journal ArticleDOI
Diffusion restricting outer membranes for greatly extended linearity measurements with glucose oxidase enzyme electrodes
TL;DR: A series of microporous and homogeneous membranes have been employed as outer membranes in an amperometric glucose oxidase enzyme electrode for the determination of glucose at concentrations substantially higher than the enzyme K m as discussed by the authors.
Journal ArticleDOI
An Enzyme Electrode for Extended Linearity Citrate Measurements Based on Modified Polymeric Membranes
Andrew Maines,Mamas I. Prodromidis,Stella M. Tzouwara-Karayanni,Miltiades I. Karayannis,David G. Ashworth,Pankaj Vadgama +5 more
TL;DR: The relative optimum concentrations of several activators (divalent cations) and cofactors such as FAD and thiamine pyrophosphate (TPP) were investigated and an extended linearity up to 100 mM citric acid was achieved.
Journal ArticleDOI
Reagentless enzyme electrode for malate based on modified polymeric membranes
Andrew Maines,Mamas I. Prodromidis,Stella M. Tzouwara-Karayanni,Miltiades I. Karayannis,David G. Ashworth,Pankaj Vadgama +5 more
TL;DR: A series of polymeric membranes have been employed as outer barriers in an amperometric malate dehydrogenase (MDH)/diaphorase (DI) or MDH/DI/NAD C /mediator enzyme electrode for the determination of malate in undiluted neutral or acidic media.
Journal ArticleDOI
Convection in planetary interiors
TL;DR: In this article, the conservation of mass, energy, and momentum of viscous flow inside a heterogeneous, compressible, rotating fluid configuration, in which the coefficient of viscosity is an arbitrary function of radial distance, and the rotation is about a fixed z axis with angular velocity ω.
