The Development of an Integrated Microengineered Ion Sensor (Inion) for Cesium
An Ion Selective Conductimetic Microsensor (ISCOM) for the detection of cesium ions was devleoped. The operating principle of an ISCOM is based on the concentration dependant change in the bulk conductivity of an ion selective membrane. Changes in conductivity are achieved by salt extraction of the …

Solid state amperometric sensor for the in-situ monitoring of slag composition and transport properties
Conventional oxygen sensors have been used for several decades for better process control in metals industries. Such devices can accurately determine the oxidation state of the molten metal phase. Investigators understand the importance of the slag phase on the quality of the final product and …

Electrochemical Modulation of Peripheral Nerves Using Ion-Selective Electrodes
… stock which require physical access for restoration or replacement. In this thesis, I examine the ion-selective membrane (ISM), a filter that discriminately transports single ions within mixed electrolytes, whose operation in ion delivery platforms does not suffer from the fundamental restriction …

Investigating Crossover in Aqueous Organic Redox Flow Batteries Using NMR Spectroscopy
There is an urgent need for low-cost long-duration energy storage, to facilitate the transition to an all-renewable electricity grid. Aqueous organic redox-flow batteries (AORFBs) are promising candidates for this application. These batteries are composed of two aqueous electrolytes with organic …

Development Of Electrochemical Sensors And Non-Covalent Monolayer Modification Of Graphene
This dissertation is focused on two main research topics. One is the development of novel electrochemical sensors (Chapter 1-5), and the other is the non-covalently modification of graphene with monolayers of receptors, also in view of the development of chemical sensors (Chapter 6-7). Good …

Influence of external environment on fluid/ion transport in confined nanoscale systems
… to the volume favors a predominant transport of ions. The environment results in a near ideal ion-selective nanoporous membrane. The selective nature of ions can be triggered in the fields like single molecule/particle sensing, preconcentration of analytes using electric field focusing and …

Self-assembly of sulfonated amphiphiles for channel-like synthetic membranes
… strategy to construct structure-defined functional materials, such as ion-selective membranes. Highly selective membranes can eventually form a basis to replace some energy- or labor-intensive purificatiion processes and can also simplify specific detection problems in the fields of …
