1. Current measurement by real-time counting of single charges
Sammanfattning : The first real-time observation of time correlated single-electron tunnelling is reported in this thesis. This is a direct detection of charge discreteness in an electrical current.When a current, I, flows through a chain of metallic islands, connected by small tunnel junctions, a lattice of charges is formed due to the Coulomb repulsion.

2. Precision Standard Model Phenomenology for High Energy Processes
Sammanfattning : The present status of particle physics is that the Standard Model has been completed with the discovery of theHiggs boson in 2012, but there is a multitude of phenomena in nature which is not accounted for by this model.Researchers are investigating possibilities for detecting new physics at the current particle physics facilities, withthe Large Hadron Collider (LHC) at the frontier.

3. Time-resolved detection of temporally correlated, single-charge tunnelling
Sammanfattning : We report real-time detection of the single charges that constitute a small electrical current, as they flow through a nano-electronic device. This represents a direct demonstration of charge discreteness in an electrical current. LÄS MER
4. Solid-State Nanopores for Sensing : From Theory to Applications
Sammanfattning : Nanopore based sensing technology has been widely studied for a broad range of applications including DNA sequencing, protein profiling, metabolite molecules, and ions detection. The nanopore technology offers an unprecedented technological solution to meeting the demands of precision medicine on rapid, in-field, and low-cost biomolecule analysis. LÄS MER
5. Corrosion of current cullector materials in the molten carbonate fuel cell
Sammanfattning : The corrosion of current collector materials in MoltenCarbonate Fuel Cells (MCFC) is investigated. The essential aimsof this investigation were to study the corrosion behaviour ofdifferent materials, in varying cathode and anode MCFCenvironments, and to study the contact corrosion resistancesbetween the MCFC current collector and electrodes.
