A wind-tunnel experiment was designed and carried out to study the effect of a surface roughness transition on subfilter-scale (SFS) physics in a turbulent boundary layer. Specifically, subfilter-scale stresses are evaluated that require parameterizations ...
The long term performance of micro-/nano-electromechanical systems (MEMS/NEMS) depends on their stability to operating conditions, contact friction, adhesion, and wear. Aluminum (Al) substrates have been chemically reacted with perfluorodecanoic acid (PFDA ...
In this study, we characterize the CCN activity of the water-soluble organics in biomass burning aerosol. The aerosol after collection upon filters is dissolved in water using sonication. Hydrophobic and hydrophilic components are fractionated from a porti ...
Block copolymers are comprised of repeating chemical groups (blocks) which commonly contain at least one hydrophilic block coupled to at least one hydrophobic block, forming an amphipathic macromolecule. This molecular arrangement drives the self assembly ...
The present invention provides methods and apparatus for coating surfaces with specially designed thioethers and amphiphilic thioethers that reduce protein adsorption and/or cell adhesion. This reduction may be achieved, for example, by controlling the spa ...
Oil-bodies are minute plant organelles (0.5-2.0 mu m diameter) consisting of an oil core surrounded by a phospholipid monolayer/proteinaceous membrane. Oil-bodies have been isolated from rapeseed seeds and demonstrated to constitute a novel type of micro-c ...
This paper describes F-based dry etching and resulting surface properties of biocompatible silicone elastomer. The etch rate of polysiloxane and surface morphology was found to be highly temperature dependent. An increase in temperature results in a signif ...
We report an extensive airborne characterization of aerosol downwind of a massive bovine source in the San Joaquin Valley (California) on two flights during July 2007. The Center for Interdisciplinary Remotely-Piloted Aircraft Studies (CIRPAS) Twin Otter p ...
Magnetic microparticles and their application in bioanalytical microfluidic systems have been steadily gaining interest in recent years. This progress is fueled by the comparatively large and long range magnetic forces that can be obtained independently of ...
Odorant receptors are an excellent example of natural superiority in binding specific small and hydrophobic molecules. Difficulties in expression, isolation and solubilisation of these receptors have been overcome recently by in vitro synthesis and incorpo ...
