One of the key points to better understand the origins of friction is to know how two surfaces in contact adhere to one another. In this paper we present molecular dynamics (MD) simulations of two aluminium bodies in contact, exposed to a range of normal l ...
The low-temperature adsorption of isolated transition metal adatoms (Mn, Co, and Fe) onto hexagonal boron nitride monolayers on Rh(111) creates a bistable adsorption complex. The first state considerably weakens the hexagonal boron nitride- (h-BN-) substra ...
The electrochemical stability of ionic liquids based on the 1-ethyl-3-methyl imidazolium EMIM cation and three different anions, dicyanoamide (N(CN)(2)), tricyanomethanide (C(CN)(3)) and tetracyanoborate (B(CN)(4)), has been investigate ...
The commonly accepted description of drops impacting on a surface typically ignores the essential role of the air that is trapped between the impacting drop and the surface. Here we describe a new imaging modality that is sensitive to the behavior right at ...
Using molecular dynamics simulations, we have studied the water-vapor and water-oil (decane) interfaces of aqueous solutions of sodium dodecyl sulfate (SDS). The water-vapor interface is often used as a model for water-oil (hydrophobic) interfaces, yet we ...
The average lifetime of an implanted pacemaker or defibrillator cable (lead) is approximately 10 years. One of the main lead failure mechanisms is deterioration of the insulation, which can be caused by chemical, biological, and mechanical processes. Each ...
We present and characterize an organic–inorganic hybrid sol–gel material, phenyl-bridged polysilsesquioxane (ph-PSQ), for use as a new highresolution resist for electron beam lithography (EBL). The resist has a unique characteristic as the only positive to ...
When aliquid drop approaches a flat solid surface, the airbeneath it is compressed,flattening the bottom of the drop andforcing initial contact to occur in aring-shape, trapping a pocketof air in its center as two wetting frontsrapidly expand botho ...
The self- and collective-diffusion behaviors of adsorbed methane, helium, and isobutane in zeolite frameworks LTA, MFI, AFI, and SAS were examined at various concentrations using a range of molecular simulation techniques including Molecular Dynamics (MD), ...
We describe the self-organization of PCBM and a cyanine dye on chemically patterned surfaces during spin coating from solution. On homogeneous surfaces, a transient bilayer forms, which in a later stage decomposes into PCBM droplets in a matrix of the cyan ...
