From Helical Starch Inclusion Complexes to Supramolecular Starch Assemblies

Conde-Petit B., Nuessli J., Heinemann C., Escher F., ETH Zürich, CH

Starch, in particular the linear amylose fraction has the ability ot form helical inclusion complexes with suitable guest molecules like monoglycerides, linear alcohols, lactones or terpenes. The helical amylose segments have a strong tendency to [...]

Computational Heat Transfer and Two-phase Flow in Miniature Tubes

Lakehal D., Narayanan C., ASCOMP, CH

We will report on our recent advances made in predicting this class of flow, using the Level Set approach, in which we have incorporated phase-change capabilities, surface tension and triple-line dynamics models based on the [...]

Simulation of filling of microfluidic devices using a coarse-grained continuum contact angle model

Narayanan C., Lakehal D., ASCOMP, CH

We present a new dynamic contact angle model applied to the fillingproblem in microfluidic devices. The level-set method is used forinterface capture. Several attempts have been made in the past decades to model contact--line dynamics [...]

A Lab-on-a-Chip using Magnetic Droplets

Lehmann U., Parashar V.K., Vandevyver C., Gijs M.A.M., EPFL, CH

We present a chip-based bio-analysis system using the two dimensional (2D) magnetic manipulation of microdroplets. The latter contain magnetic microparticles which serve as force mediators for the droplet actuation. In combination with a changeable field [...]

New One-Particle Monte Carlo Method for Nanoscale Device Simulation

Brugger S.C., Schenk A., Swiss Federal Institut of Technology, CH

A new one-particle Monte Carlo iteration scheme has been found toself-consistently take into account generation-recombinationprocesses. The basic idea is to couple the BTE not only with thePoisson equation, but also with the continuity equation by [...]

Cubic or monoclinic Y2O3:Eu3+ nanoparticles by flame spray pyrolysis

Camenzind A., Strobel R., Pratsinis S.E., ETH Zürich, CH

Continuous, single-step synthesis of cubic monocrystalline Y2O3:Eu3+ nanophosphor particles (10 -20 nm in grain diameter) is achieved by flame spray pyrolysis (FSP). The effect of FSP process parameters on product particle characteristics was investigated by [...]
