Theory of graphene transport properties
… it is essential to understand its electron transport properties and in particular the main factors limiting its transport mobility. In this dissertation, we study the transport properties of graphene in the presence of electron-hole puddles induced by charged impurities which are invariably …

Computational methods for transport properties
… so the permeation happens when we observe a transport of the antibiotic through a porin. In this thesis we will focus on some computational methods, which are suitable to increase our understanding of transport processes. We will start with a post elaboration algorithm, that can be used to …

Transport properties of anisotropic superconductors
… and UBe13 under pressure) the normal state transport properties at low temperatures behave qualitatively as one would expect if electron-impurity interactions were the dominant source of scattering. The experimental data on ultrasonic attenuation and thermal conduction in the superconducting …

Transport properties of synthetic nanopores
… to build and control such small devices. Surface properties, thermal fluctuations and the discreteness of matter dominate at the nanoscale, producing phenomena not observed in the microscale. Indeed, little is known about the molecular level dynamics inside nanopores or the mechanism by which …

Transport properties of DNA nanostructures
… in a lipid bilayer membrane. However, the transport properties of DNA nanostructures and the underlying mechanism have remained relatively unexplored. Here, several simulation studies focusing on the transport properties of DNA nanostructures are pre- sented. Specifically, a comprehensive …

Transport properties of micellar solutions and microemulsions.
Binary nonionic surfactant-water systems were studied prior to the more complex nonionic surfactant-water-oil systems. Phase diagrams were determined for the tetraoxyethylene dodecylether (C[12]E[4])-water and the Brij 30-water systems; the available hexaoxyethylene dodecylether (C[12]E[6])-water …

Molecular transport properties of sodium/dicarboxylate cotransporters
The Na+/dicarboxylate cotransporter (NaDC1) plays important roles in absorption of citric acid cycle intermediates from the intestinal and renal tubular lumen. NaDC1 influences the homeostasis of citrate, which may be associated with the formation of kidney stones. The studies in this dissertation …

Transport properties of electrons in potassium bromide
The photocurrents in lightly colored KBr crystals were measured as o function of electric and magnetic fields in the temperature range of 4.2 K to 78 K. The wavelength dependence o£ the photocurrent was determined in the same range of temperature. The symmetry of the conduction band at 4.2 o K was …

Magneto-transport properties of giant magnetoresistive systems
To understand the cause of the giant magnetoresistance effect, we have systematically investigated magnetothermopower, magneto-thermal conductivity and magnetoresistivity in both ferromagnetic/non-magnetic multilayers and granular solids which exhibit the giant magnetoresistance effect.

The transport properties of superconducting-normal interfaces
The resistive and thermoelectric properties of a series of SNS sandwiches, containing different concentrations of impurity in the superconductor, have been measured. The system used for this work was In/W/In with up to 10% lead added to the indium. A technique was developed in which the interfaces …
