The scientists at A.F. Ioffe Physical Technical Institute, Russian Academy of Sciences, decided to restore the production of semi-conductor devices for pulse radiotechniques which was interrupted at the beginning of the 1990s. These devices have recently found wide application in different areas of technology: in ultra broadband apparatuses of communication, geopositioning and following, radars where a signal of high power should be generated for short time intervals. The idea of creating the devices belongs to a group of scientists under the supervision of Kardo-Sysoev.
It is possible to transfer information using very short electrical pulses with the duration less than one nanosecond. The pause between the adjacent pulses is also very short and therefore the volume of information can be enormous. However, powerful transmitters are necessary to send these signals for distances more than 10-15 kilometers. The task has been solved at the laboratory of fast processes at A.F. Ioffe Physical Technical Institute, Russian Academy of Sciences, where a new class of diodes and transistors has been developed. Their combination in the scheme gives the necessary transmitter, the source of ultra short signals in ultra broadband range.
Industrial production of these devices does not exist anywhere in the world for a while but the appropriate market with a turnover of several billion dollars should appear very soon. Russian scientists have a great advantage over their partners from other countries because a significant and unique experience has been accumulated in Russia for many years. "Of course, our western colleagues will catch up with us but at the moment our technologies are more advanced and it pays to buy the devices for ultra broadband systems in Russia. - says Kardo-Sysoev - All the air ultra broadband radars of super high resolution in the USA use our devices."

Gravitational wave kicks monster black hole out of galactic core

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.
