Nano-engineering Core/Shell Quantum Dots for Ultimate Utility in Light-emission Applications

Htoon H., Hollingsworth J.A., Los Alamos National Laboratory, US

Quantum-confinement effects have been used for decades to tune semiconductor opto-electronic properties. More recently, particle-size control as the primary means for properties control has been succeeded by nanoscale hetero-structuring. In this case, the nanosized particle [...]

Unravelling adsorption and alignment of amyloid fibrils at interfaces by probe particle tracking

Isa L., Jung J-M, Mezzenga R., Jordens S, ETH Zürich, CH

We report the first direct, non-invasive experimental evidence of a 2D isotropic–nematic transition for highly anisotropic nanoparticles at liquid–liquid interfaces by using passive fluorescent particle tracking. In order to illustrate the potential of this approach [...]

Numerical Visualization and Quantification of Chaotic Mixing for Micromixers

Kang T.G., Kwon T.H., Pohang University of Science and Technology, KR

We present a systematic way of visualization and quantification of mixing in chaotic micromixers with a periodic mixing protocol. We name it colored particle tracking method, which consists of three steps. One is flow analysis [...]
