CNSE spintronics lab research shows silicon can maintain a permanent magnetic field above room temperature, which could help to develop more effective magnetic semiconductors and future spintronic devices
Ferromagnetic hysteresis loops taken at three temperatures measured from the Mn implated Si.
Silicon is best known as the material used to make semiconductor computer chips with integrated circuits. Today, scientists at the College of Nanoscale Science and Engineering (CNSE) at the University at Albany published research that could lay the foundation for using silicon to develop chips with magnetic properties, potentially impacting the development of electron-spin-based or "spintronic" devices.
Spintronics exploits the quantum mechanical property of electron spin, as well as its charge state. Potential spintronics applications include magnetic random access memory (MRAM), which could enable the development of computing devices that are always on, dont require time to "boot up" and dont require a traditional hard drive.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
