Scientists create smallest semiconductor laser that works in visible range at room temperature (08/06/2020)

An international team of researchers has announced the development of the world's most compact semiconductor laser that works in the visible range at room temperature. According to the authors of the research, the laser is a nanoparticle of only 310 nanometers in size (which is 3,000 times less than a millimeter) that can produce green coherent light at room temperature. The research article was published in ACS Nano.

EPFL researchers have developed electronic fibers that, when embedded in textiles, can be used to collect data about our bodies by measuring fabric deformation. Their technology employs flexible transmission lines and offers a host of applications, including in the medical industry.

Watching single protons moving at water-solid interfaces (31/05/2020)

The H+ proton consists of a single ion of hydrogen, the smallest and lightest of all the chemical elements. These protons occur naturally in water where a tiny proportion of H2O molecules separate spontaneously. Their amount in a liquid determines whether the solution is acidic or basic. Protons are also extremely mobile, moving through water by jumping from one water molecule to another.

Nanoneedles to increase the capacity and robustness of digital memories (31/05/2020)

Researchers at the UAB, ICMAB and the ALBA Synchrotron, in collaboration with the UB and ICN2, have developed a new technique to locally modify the properties of a metamagnetic material. The method consists of applying local pressure to the surface of the material using nanometric needles and allows a much more easy and local modification than current methods. The research opens the door to a more accurate and precise control of magnetic materials and allows to improve the architecture and capacity of magnetic digital memories.

Physicists Build Hybrid Quantum System by Entangling Molecule With Atom – Could Enable Large-Scale Quantum Computers (28/05/2020)

Physicists at the National Institute of Standards and Technology (NIST) have boosted their control of the fundamental properties of molecules at the quantum level by linking or “entangling” an electrically charged atom and an electrically charged molecule, showcasing a way to build hybrid quantum information systems that could manipulate, store and transmit different forms of data.
