New material with wide applications developed in Russia

14 Jul '17
Physicists at the Moscow Lomonosov State University (MSU) and the Kant Baltic Federal University, based in Russia’s westernmost enclave of Kaliningrad, have developed a new multiferroic, a ferromagnetic material whose magnetic field is permanent and always polarized electrically.

“We have developed and studied a new functional composite material with manifest multiferroic properties, based on polymer matrix with ferromagnetic and ferroelectric microparticles added,” said Dr. Nikolai Perov of MSU’s solid-state physics department.

“The materials we have come up with belong to multiferroics with a potentially broad range of applications. Unlike multiferroics we already knew of, these are very easy to produce; a sample of any shape and size can be made. The materials are supple and resistant to aggressive environments. As we develop the effort towards its economic applicability, similar materials with even better properties will be looked for,” Dr. Perov added.

ZHUKOVSKY, July 18. /TASS/. Russian Helicopters (part of the Rostech corporation) has displayed the prototypes of rotorcraft unmanned aerial vehicles (UAVs), or drones, for ice observation and operation in the Arctic environment, as well as for monitoring and remote sensing, the company’s press service reported on Tuesday.

"The VRT 300 system has been designed and is being exhibited at the MAKS-2017 in two versions: Arctic Supervision, which has a side-looking radar for ice observation and operation in the Arctic conditions, and Opticvision, which has an increased flying range for monitoring and remote sensing," the company said in a report.

The VRT300 Arctic Supervision was designed to develop the transport system of the Northeast Passage and help explore the Arctic region. For these purposes, the system was equipped with a high-resolution X-band side-looking radar that makes it possible to quickly scan changes in the ice.

The system may be used to transport various cargoes (products and medicine) between a ship and a polar station. The unmanned helicopter can also measure ice thickness along the ship’s route, conduct search and rescue operations at sea and assess large ice fields in which polar stations can be set up.


The VRT300 Opticvision was designed to develop the system of diagnostic assessment, prevention and liquidation of emergency situations in exploration and transportation of energy sources. The system’s functions also include checking power transmission lines, mapping, cargo transportation, search operations, and monitoring the environment and road facilities. The system has a mobile drone operation center that is also presented at the MAKS-2017 International Aviation and Space Salon.

Moscow develops new self-healing technology for roads

19 Jul '17
Scientists at MISiS, a top Moscow-based technology university in Russia, have developed production technology for self-healing asphalt-concrete materials to be used in making roadbeds, the university website announced. With the new method of eliminating roadbed cracks road repairs would take just a few hours instead of today’s week and cost about 30% of the current cost.

The material consists of electrically conductive multiwall carbon nanotubes (MWCNTs) called “Taunit-M” which are said to possess unique characteristics such as high inductance receptivity. Bringing the additive into conventional roadbed adds little to the cost of repair while triggering the self-healing effect.

To kick-start the process, a new machine, described as a hybrid of a road-roller and microwave, must be used. It heats the surface, and microwaves set nanotubes in motion, which is said to cause road cracks and holes to self-heal. In the technique, no additional roadbed material would be required—riding over the area to be repaired is quite enough to cure the damaged spot, MISiS said.

The approach itself is hardly unique globally; scientists in the Netherlands, China and other countries also set their sights of the problem. However, MISiS’ foreign colleagues are reported to use metallic fiber as additive. The Moscow researchers believe their proprietary method beats the competition in effectiveness as it brings about inductance heating in the thin bitumen film only and requires no change in the composition of asphalt-concrete mixture.

Protons against cancer: new Russian discovery

20 Jul '17
Russian scientists have successfully completed a series of experiments aimed at fighting cancer with proton beams.

A team led by Svetlana Zaichkina of the Institute of Theoretical and Experimental Biophysics in Pushchino outside Moscow reportedly experimented with mice that had various cancers. The animals were exposed to proton radiation with a varying number of sessions, duration per session, and beam power. The experiments resulted in tangible improvements in the mice’s health, with their tumor growth slowing down by a quite noticeable five to six times. Targeted proton therapy aimed only at the tumors proved the best: more that 80% of the mice treated like that are reported to have had their primary cancers conquered.

That said, however, the experimenters reportedly failed to avoid setbacks. About 60% of what they had thought to be successful mice cases eventually developed new tumors. Nonetheless, the mice that had received targeted proton treatment lived three months longer than their congeners, while the animals that suffered no relapse lived as long as two years, the typical average life expectancy for healthy mice.

That led the experimenters to the conclusion that proton therapy is more effective and safer that conventional radiotherapy, especially if used targetedly on tumors exclusively. With the kind of efficacy, treatment could be limited to just a few proton radiation sessions, if not only one. That would help lower the cost of therapy and save the lives of patients with brain tumors and other cancers currently deemed inoperable.

Russian Humanoid Robot 'Fedor' Learns to Shoot Using Both Arms
F.E.D.O.R., which stands for Final Experimental Demonstration Object Research is the first domestic humanoid robot, created within the framework of the Foundation of Advanced Studies.


It will replace humans in places of high risk – for example, in rescue operations and in space. It is planned that in 2021 Fedor will go into orbit on the Russian next-generation Federation spacecraft.

“The robot Fedor has the best kinematics in the world among robotic androids: he is the only anthropomorphic robot in the world, able to perform both longitudinal and cross sit splits. The mechanics of other androids existing in the world do not allow for such freedom of movement,” a report released by the Foundation of Advanced Studies read.

As explained in the report the flexibility of the rescue robot is necessary in order to enable it to overcome a variety of obstacles.


Connectivity with operator

Another unique quality of Fedor is its system of reverse torque or sensory communication. This allows for the operator to be immersed in the physical circumstances in which the robot is located.

“When it comes to such a complex device as an anthropomorphic robot with several control modes, the sensor system must regulate complex mechanical movements, associated, for example, with balance and dynamics,” the report read.

Robot sensors, which measure speed, angular and linear position and many other data information, arrive directly at the control computer.
So if the robot rests against a wall and cannot move forward the person wearing the control suit receives this resistance and helps it in navigation.

Mind-blowing independence of Fedor

The robot is able to independently navigate in the city and cross-country, work with tools and drive vehicles.

It can be controlled both in the standalone mode and in the combined mode. Some of the functions are performed automatically by the robot, whereas others are specified by the operator.


In addition to the robotic platform, the network includes a combined remote control system with a so-called control suit.

At the heart of this system is a mathematical model of combined control; its features matching those of a human body.
Earlier, it was reported that Fedor managed to display skills firing using both arms.

“We are not creating a terminator but artificial intelligence which will have a great practical importance in various fields,” Deputy Prime Minister Dmitry Rogozin said.

It is expected that “Fedor” will help astronauts work in open space and serve at the station.

“The unmanned launch and autonomous flight of our new spacecraft will take place in 2021. … It is expected, and all relevant decisions have already been made, that the robot Fedor will be the first pilot," Yevgeny Mikrin, Roscosmos general designer of the manned spacecraft, said.

Russia's Energia Space Corporation earlier said that the Federation, 80 percent of which is built of composite materials. would be manufactured by 2021.

The new spacecraft will replace the aging Soyuz spacecraft in supporting low Earth orbit missions

I've read about reinforcing russian nuclear fleet at https://warsawinstitute.org/ , article about "Potomkins fleet"! I've never expected that Russia will develop it's nuclear arsenal in such a short time. I mean, we knew about missiles and stuff like that - but submarines in addition to it sounds like a much bigger threat.
