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."

Tiny lasers from a gallery of whispers

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
