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 ...

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 ...

More accurate biopsy by augmented reality

The University of Twente is currently developing a smartphone technology based on the usage of Simultaneous Localization And Mapping (SLAM) and augmented reality (AR). This technology enables medical personnel to reconstruct ...

Bicycles reacting to speed for stable cycling

A Dutch consortium including the University of Twente developed an electrical bicycle that prevents elderly people from falling. The smart assistive bicycle, called SOFIE, increases stability by via drive-off assistance and ...

Airbag prevents tanker trucks from tipping over

Dr Erik Eenkhoorn has designed a system that can secure liquid loads, making the transport of bulk liquids much safer. Inflatable components prevent tanker trucks from tipping over, and reduce fuel consumption, as well. Erik ...

Electronics and optics on one chip

Electronics and light don't go well together on a standard "CMOS' chip. Researcher Satadal Dutta of the University of Twente now succeeds in introducing a light connection into the heart of a semiconductor chip. In this way, ...

Concentrated CO2 enables growth spurt in algae

A new technology captures CO2 from ambient air efficiently and inexpensively. Researchers at the University of Twente used the CO2 captured to cultivate algae, but the technology can also be used in a closed cycle to store ...
