Nanowerk January 2, 2018 Researchers in Germany are developing a quantum sensor that will be able to precisely measure the tiny magnetic fields we can expect to see in the next generation of hard discs. The sensor itself is just slightly larger than a nitrogen atom, with a specially grown ultra-pure diamond crystal as a substrate. The combined nitrogen-vacancy center acts as the actual sensor. Using electron spin resonance spectroscopy, they can detect magnetic fields with nanometer accuracy, and determine their force opening an extraordinary range of applications. Potentially the sensor can be used to measure brain activity. Read […]

Flexible bonding: hard and soft at the same time
Fraunhofer Research News January 2, 2018 Researchers in Germany have developed a new material called MetAK which is comparable to commercially available resins. Its stiffness can be determined by two hardening mechanisms: irradiation with UV light, and heat. The areas that should remain flexible are not irradiated; they are instead treated with heat, which cures them. As the rigidity is very easily adjustable, it is possible to flexibly adjust the material to the frequency range of the vibrations and compensate for them. MetAk can be cast in a specified shape making it attractive for orthopedic applications. Read more.
