Playfully discover atom manipulation

Online simulation game makes graphene research available to the public

10-Jul-2019

The team of Toma Susi at the University of Vienna uses a state-of-the-art electron microscope, the UltraSTEM, to manipulate strongly bound materials with atomic precision. Since the instruments used are fully computerized, it is possible to show in a simulation how researchers actually use them. ...

Original kilogram replaced

New International System of Units (SI) entered into force

23-May-2019

In addition to Ampere, Kelvin, Mol and Co., the kilogram also is now defined by a natural constant. In concrete terms, this means that the original kilogram, which has been the measure of all things for 130 years, has now served its purpose in Paris. This is made possible by the single crystals ...

The holy grail of nanowire production

22-Feb-2019

Nanowires have the potential to revolutionize the technology around us. Measuring just 5-100 nanometers in diameter (a nanometer is a millionth of a millimeter), these tiny, needle-shaped crystalline structures can alter how electricity or light passes through them. They can emit, concentrate and ...
