Van Oorschot, R. (author), Perez Garza, H.H. (author), Derks, R.J.S. (author), Staufer, U. (author), Ghatkesar, M.K. (author)We present the development of a microfluidic AFM (atomic force microscope) cantilever-based platform to enable the local dispensing and aspiration of liquid with volumes in the pico-to-femtoliter range. The platform consists of a basic AFM measurement system, microfluidic AFM chip, fluidic interface, automated substrate alignment, external...journal article 2015

(author), Scarpas, A. (author)As a widely accepted concept, bitumen consists of four fractions that can be distinguished by their polarity. Highly polar asphaltene micelles are dispersed in a viscous phase of saturates, aromatics and resins (maltene phase). Different concentrations of asphaltenes in the bitumen result in a range of mechanical response properties. In an...journal article 2015
