  • Waves of ice inside a droplet
    A droplet falling on a surface that is considerably supercooled, will freeze in a way that wasn't ever observed before. Instead of the well-known growth of crystals, a colder surface results in mov...
  • Avoiding bubble trouble in gas evolving electrodes
    Bubbles are known to influence energy and mass transfer in gas evolving electrodes. Many electrochemical reactions produce gas that can lead to bubbles forming at the reaction site. Those bubbles c...
  • Crystal building by tiny magnets
    Tiny magnetic balls are a popular toy for building great 3D shapes. Imagine you'd want to use this principle for building crystal structures by self-assembly, is a spheroid still the best building ...


  • Lab-on-a-chip helps search for human DNA at crime scenes
    Thanks to the work carried out by University of Twente PhD candidate Brigitte Bruijns, crime scenes can now be inspected on the spot for the presence of human DNA. In her PhD thesis, she describes ...
  • Nano brush will 'smell' food freshness
    A coating made of nano size hairs, a polymer brush, has many more potential applications than the current ones, according to Sissi de Beer of the University of Twente. Until now, the brushes are ma...
  • Looking inside 3D nanostructures without leaving a trace
    Discovering what is inside a three-dimensional (3D) nanostructure, is no longer a matter of cutting slices, thus breaking it up and destroying its functionality. Scientists from the University of T...


  • 3D printing of living cells
    Using a new technique they call 'in-air microfluidics', University of Twente scientists succeed in printing 3D structures with living cells. This special technique enable the fast and 'on-the-fly' ...


  • Microchip for ultrafast separation and purification of DNA fragments
    The new chip is capable of fractionating DNA fragments within just a few minutes, while conventional approaches take hours. The chip does this in high resolution and also purifies the fragments; it...
  • Coffee physics
    For anyone who has marveled at the richly colored layers in a cafe latte, you're not alone. Princeton researchers, likewise intrigued, have now revealed how this tiered structure develops when espr...


  • Perfect crystals from 'flying' drops
    Crystals that don't experience mechanical stress during growth, will be of superior quality. Levitate the liquid metal, is the idea behind the new project 'Perfecting metal crystals', led by the Un...
