We study catalytic Janus particles and Escherichia coli bacteria swimming in a two-dimensional colloidal crystal. The Janus particles orbit individual colloids and hop between colloids stochastically,
Wavelength dispersion X-ray fluorescence spectrometry (WDXRF) is a non-destructive technique and therefore attractive for gunshot residues (GSR) analysis. It is well known for determination of inorgan
Video of superparamagnetic colloidal particles which are confined in a microchannel of 30µm width. The particles are driven into motion by tilting the microscope. Two...
