The overall goal of this expedition was the acquisition of geophysical data on the Vøring Plateau and the southernmost part of the Lofoten Basin to improve the understanding of the subsurface structures and geological processes at four sites (U1571-

We investigate commonly occurring defects in block copolymer thin films assembled on chemically nanopatterned substrates and predict their probability of occurrence by computing their free energies. A theoretically informed 3D coarse grain model is u

Ternary blends of cylinder-forming polystyrene-block-poly(methyl methacrylate) (PS-b-PMMA) and low molecular weight PS and PMMA were directed to assemble on chemically patterned surfaces with hexagonal symmetry. The chemical patterns consisted of str

Recent developments in block copolymer lithography suggest that triblock copolymers could enable fabrication of ultrasmall features over large areas. While the majority of past work with block copo...

Hugh Brown has shown that interfacial entanglements govern adhesion between two polymers. We demonstrate this for three systems by adding interfacial chains via chemical coupling. The adhesion between polypropylene (PP)/amorphous polyamide (aPA) was

The majority of past work on directed assembly of block copolymers on chemically nanopatterned surfaces (or chemical patterns) has focused on AB diblock copolymers, and the resulting morphologies have generally corresponded to equilibrium states. Her

Self-assembling sphere-forming block copolymers that normally adopt a hexagonal packing in thin films are directed to assemble on chemically patterned surfaces into their three-dimensional bulk-like body-centered cubic morphology; two-dimensional man

A newly developed formalism is described, in which models that have been traditionally addressed using field-theoretic methods are solved by resorting to Monte Carlo simulations in arbitrary ensembles. In the context of block copolymer melts, the for
