Solute transport through regional-scale fractured rocks and heterogeneous porous media typically exhibits several “anomalous” features including 1) different growth rates along different directions, due to an anisotropic depositional or structural geologic environment; and 2) channeling along preferential flow paths. Simulating such plume characteristics can be computationally intensive using a...

The diverse physical properties of membranes play a critical role in many membrane associated biological processes. Proteins responsible for membrane transport can be affected by the lateral membrane order and lateral segregation of proteins is often controlled by the preference of certain membrane anchors for membrane phases having a physically ordered state. The dynamic properties of coexisti...

Classical molecular dynamics simulations are used to present a detailed atomistic picture of the instantaneous local structures of water and the structural evolution of stationary and dynamically evolving graphene-water interfaces. The confinement effects are strongly coupled to the nature of the interface, which eventually governs its nanoscopic structural arrangements and interface dynamics. ...

Physical properties affecting transport processes inside the gas diffusion layer (GDL) in fuel cells mainly depend on the microscopic structure of its pore space. The presented characterization of the pore space is based on geometric 3D graphs, representing the complex microscopic structure. This description of the open volume contains the essential information on the geometrical structure of t...

A first medium term monitoring of atmospheric transport and distribution for persistent organic pollutants (POPs) in Bjørnøya (Bear island) air samples has been performed in the period between week 51/1999 and week 28/2003. A total of 50 single compounds consisting of polychlorinated biphenyls (33 congeners), hexachlorobenzene (HCB), hexachlorocyclohexane isomers (alpha-, beta-, gamma-HCH), alp...
