Increasing the effectivity of condensation through electrowetting

Researchers of the department of Physics of Complex Fluids of the University of Twente's MESA+ institute have succeeded in increasing the effectivity of condensation through gravity-driven electrowetting. "We have been able ...

Gold 'micro jewels' from the 3-D printer

Thanks to a laser technique that ejects ultra-tiny droplets of metal, it is now possible to print 3-D metal structures—not only simple 'piles' of droplets, but complex overhanging structures, as well, like a helix measuring ...

Hot nanoparticles produce giant and explosive bubbles

When gold nano particles in water are illuminated by a laser, they get very hot: well above the boiling point of water. The formation of vapour bubbles caused by this, is well-known. New experiments, however, using a very ...

Controlling photon energy density in opaque materials

Just like merry people at a party, photons perform random walks through white paint; but their density remained out of control. Recently, scientists at the University of Twente in the Netherlands have managed to control the ...

Enhancing 'breath figures' using electric fields

Breath figures are the typical condensation patterns we know from breathing on a cold surface. In physics, this term is used to describe dropwise condensation patterns. The evolution of these patterns and roll-off of droplets ...

Parkinson-related protein is 'tunable'

Fibrils of the protein alpha-synuclein, that plays a role in Parkinson's disease, form a stiffer and stronger network in water, when temperature is increased. Researchers of the University of Twente show that this has to ...

Bitcoin more vulnerable to attack than expected

Calculations by University of Twente researchers show that Bitcoin is more vulnerable to attack than people had always assumed. If some Bitcoin users were to form a group that controls 20 percent of the currency's computing ...
