  • Designing a better superconductor with geometric frustration

    Superconductors contain tiny tornadoes of supercurrent, called vortex filaments, that create resistance when they move. This affects the way superconductors carry a current. But a magnet-controlled "switch" in superconductor configuration provides unprecedented flexibility in managing the location o more

  • The limits of friction

    Friction is created when two surfaces slide one on top of the other. Since this consumes additional energy, this so-called sliding friction is considered an irksome yet inevitable aspect of dynamic processes. However, to set a stationary object in motion, its static friction must be overcome first. more

  • Precisely controlling plastic particles

    Physicists at the University of Bayreuth have discovered plastic particles that enable the movements of individual particles to be observed without interruption and to be precisely controlled. New microchips which are only a few tenths of a millimetre in size and which are capable of providing such more

  • Dr. Daniel Kopetzki

    born 1983, studied chemistry at the University of Regensburg and received his doctorate from the Max Planck Institute of Colloids and Interfaces in Potsdam, in the Department of Colloid Chemistry. Since Sept. 2011, he has been working as a post-doctoral fellow for Prof. Dr. Seeberger at the Max Plan more



Colloid A colloid or colloidal dispersion is a type of homogenous mixture . A colloid consists of two separate phases: a dispersed phase and a continuous phase. In a colloid, the dispersed phase is made of tiny particles or droplets that are dist ... more
