Siberians offer new polymers with improved biocompatibility

29 Apr '16
Researchers from the Tomsk Polytechnic University and the Krasnoyarsk-based Institute of Biophysics (both in Siberia) in partnership with their German colleagues are working on materials for biopolymers to be used in medicine. The team has developed a technique making the biopolymers more compatible with the human tissues than their current competition in the market. Their biopolymers are said to be able to interact with our natural bodily fluids, including blood.

Biopolymers are widely used in medicine across countries to treat, repair and regenerate wounds, cartilages and joints. The materials act as a replacement for a damaged area, letting new living cells grow around them, and then degrade without any harm to the body. However, the surface of a biopolymer doesn’t get moistened with water or water solutions, which makes it harder for the new cells to grow over. The scientists purposed to alter the property of polymer surface to address the problem.

According to Roman Surmenev who runs the Tech Center at Tomsk Polytechnic, the researchers treated biopolymers in high-frequency plasma, a method of changing properties of material in a very thin surface layer without damaging the structure of a biopolymer itself. This is expected to keep the key physical, mechanical and biological properties of the material, the scientist said.

“Now we have plans to extend research and work with other biodegradable polymers,” Mr. Surmenev added.

The results of the research have been published in Material Letters.

MIPT research may help look for new drugs

4 May '16
Scientists at MIPT, one of Russia’s leading tech universities in Moscow, have developed a method of simulating cellular membrane response to drug and toxin molecules, a way of analyzing drugs’ impact on human cells prior to administering the drugs, and studying ageing mechanisms without any experiments, portal Scientific Russia reported. An overview of the study was published in Journal of Chemical Theory and Information.

The key advantage of the method is the ability of a researcher to identify and quantify all possible changes in a molecule and track the location of all atoms simultaneously, with each structure variant getting its specific value which could be used later on for statistical analysis. The developers processed data using the principal component method, a technique that enables the extraction of most essential data out of an ocean of all others.

Looking into lipids and studying single atoms is expected to help predict impact drugs and toxins may have on cells and the human body as a whole, thus stepping up the search of new pharmaceutical compositions and drug candidate tests considerably. In addition, the simulation can help study ageing mechanisms which some believe are closely linked to changes in cellular membrane structure.

At MIPT, new cooling for next gen computers developed

28 Apr '16
Physicists at Moscow’s MIPT, a leading Russian university focused on physics and technology, also known as Phystech, have developed a cooling system or the plasmon components of optoelectronic chips which are expected to run tens of thousands of times faster than today’s computers.

Their research has shown that using efficient multilayer thermal interfaces several nano- and micrometers thick in combination with conventional cooling systems can lower the temperature of a chip to a level which is just about 10 degrees Celsius above the ambient temperature. This appears to be opening much broader horizons for the use of optoelectronic chips in areas ranging from supercomputers to compact electronic devices, and traditional cooling systems reinforced with the new solution may still be widely used.

Modern computer technologies are built around electrons that move. The development of such technologies is severely hampered by physical factors that make it impossible to reduce the size of a device and lower an operating frequency.

Today, conventional electronic ICs operate about as fast as they possibly can. In fact, the ability of a computer to run faster is not only dependent on the capacity of one kernel; it hinges also on the speed of data exchange between kernels. Conventional electrical copper couplings in chips have a very limited throughput capacity, and no increase in chip capacity can be achieved with them. In simpler words, doubling the number of kernels won’t help double the capacity of your computer.

In an attempt to address the problem, physicists turned to optics, trying to replace electrons with photons. If they pull it off, the next generation of computers called optical computers will arise, capable of operating at least tens of thousands of times faster than the computers we have today.

Replacing electrons with photons is expected to enable the transmission of large volumes of data between chip kernels virtually within a split second. That’s why a large number of research teams across the world, including the leaders in the sector such as IBM, Oracle, Intel, HP and others, are working on the development of super-fast optical systems that could help retire electronic ones. Photonics is an area that already attracts billions of dollars in investment.

Nanomaterials for new memory devices developed in Voronezh

5 May '16
Scientists at the Voronezh State University (VSU) in Central Russia have developed new magnetic nanostructured materials which could be used to make next gen memory devices.

The VSU team is said to have aimed to develop Si-Me based nanostructured materials “with an optical magnetization reversal effect” to come up with new memory components.

As a result of research, the team is reported to have developed materials that are expected to enable “ultra-high speed,” an improvement that stems from an innovative method of storing data no devices available today currently use. Immediate markets for the new materials include photonics, microsystem instrumentation, and memory devices.

VSU is one of Russia’s largest universities, running 18 departments with as many as 20,000+ students from 75 Russian regions. More than a thousand foreign students from 80 countries study there every year, with a total of about 15,000 from 141 foreign countries trained in Voronezh over the past 50 years.

No, Russia is Not in Decline – At Least Not Any More And Not Yet
Hostile western analysis of Russia consistently ignores the country's inherent strengths

Samon Saradzyan

We're comfortable
Originally appeared at ft.com
A survey of recent writings on Russia by western scholars reveals a widely-held view that the largest of the 15 post-Soviet republics has continued to decline in the 21st century.

Yet an examination of the data suggests that Russia has actually risen in comparison with some of its western competitors.



Neil Ferguson, the British, Harvard-based historian, wrote in 2011 that Vladimir Putin’s Russia was in decline and “on its way to global irrelevance.” His Harvard colleagues Joseph Nye and Stephen Walt hold similar views. “Russia is in long-term decline,” Nye wrote in April 2015; also last year, Walt wrote of Russia’s decline at least twice. Other western thinkers who have pronounced Russia’s decline in the 21st century include John Mearsheimer of the University of Chicago, Ian Bremmer of Eurasia Group, Nicholas Burns of Harvard University and Stephen Blank of the American Foreign Policy Council.

Others go further. Alexander Motyl of Rutgers University recently wrote of a “coming Russian collapse”. Lilia Shevtsova, a Russian scholar affiliated with the Brookings Institution, believes the collapse has already begun.

But is Russia really in decline, as western scholars claim? A comparison of its performance with the world as a whole or with the west’s leading economies suggests that the claim that post-Communist Russia has continued its decline into the 21st century is highly contestable at the very least.

I have compared Russia with the US, the UK, France, Germany and Italy – the west’s biggest economy, western Europe’s four biggest and all of the west’s nuclear powers – in the period 1999 to 2015 (with some exceptions when data is not available).

I relied on data supplied by the World Bank, the Stockholm International Peace Research Institute and the World Steel Association, turning to data from national governments only in the absence of data from the three organisations.

Single-variable comparisons: Russia has gained against the west but may have declined compared with the world as a whole

One traditional way of measuring nations’ power relative to each other is to compare their gross domestic product. By this measure, Russia gained economically on all of its competitors as well as on the world as a whole in 1999-2015.

Russian GDP was equal to less than 5 per cent of US GDP in 1999. That share grew to 6 per cent in 2015, a 36 per cent increase. Over the same period, Russia’s share of global GDP increased by 23 per cent, from 1.32 per cent in 1999 to 1.6 per cent in 2015. Meanwhile, the US, UK, French, German and Italian shares in global GDP declined by 10 per cent, 11 per cent, 19 per cent, 20 per cent and 32 per cent, respectively.

It is well known that the Russian economy has been declining since 2014. According to the World Bank, it is poised to contract by 1 per cent yet again in 2016 before it resumes growth. However, this projected decline will not erase the cumulative gains that the Russian economy has made since 1999 against those of the US, UK, France, Germany and Italy and against the world as a whole.

Another single-variable approach to gauging the power of nations is to measure their energy consumption, as proposed by the Russian thinker Pobisk Kuznetsov. Using this approach (based on country data for 1999-2012 and World Bank data for 1999-2014) suggests that Russia has gained on all its competitor nations.

Russian energy consumption equalled 26.21 per cent of US energy consumption in 1999, rising to 33.16 per cent in 2012. It rose even more against the other countries. In contrast, my calculations show that Russia’s share in world energy consumption was 10 per cent less in 2014 than it was in 1999. However, all of its competitors lost even greater share in that period.

Multi-variable measurements: Russia has risen

A calculation of the Geometric Indicator of National Capabilities, proposed by Kelly Kadera and Gerald Sorokin, suggests Russia’s power is rising in comparison with its competitors.

The GINC measures national power as the geometric mean of the following ratios:

  • TPR = total population of country ratio;
  • UPR = urban population of country ratio;
  • ISR = steel production of country ratio;
  • ECR = primary energy consumption ratio;
  • MER = military expenditure ratio;
  • MPR = military personnel ratio.
The GINC shows Russia’s power rising by 6.53 per cent in 1999-2014, while the power of the US, UK, France, Germany and Italy declined 13.14 per cent, 24.42 per cent, 24.23 per cent, 29.92 per cent and 27.29 per cent respectively in 2014 compared with 1999.

Another multi-variable measure is that designed by Chin-Lung Chang of Fo-guang University, which is one way the Chinese scholars measure national power.

Chin-Lung’s formula is this: Nation’s Composite Strength = (Population Strength + Economic Strength + Military Strength)/3, where:

  • Critical mass = (Nation’s population/world population) x 100 Critical mass + (Nation’s area/world total) x 100.
  • Economic Strength =(Nation’s GDP/world GDP) x 200
  • Military Strength = (Nation’s military expenditures/world military expenditures) x 200.
Applying Chin-Lung’s approach shows Russia’s power rising by 28 per cent between 1999 and 2015, while the power of the US, UK, France, Germany and Italy decreased by 6 per cent, 15 per cent, 29 per cent, 29 per cent and 41 per cent, respectively. Moreover, even if we to alter Chin-Lung’s approach by reducing the proportional weight of land area and military strength and adding a measurement innovative strength, such as the number of patents filed by residents, the results show Russia rising faster than the US, with the other competitors declining.

Conclusion

Taken together, these measures suggest strongly that Russia has either risen or retained its position relative to its five competitors and the world as a whole so far in the 21st century.

It is well known that the Russian economy stopped growing in 2014 and started declining. The World Bank estimates that Russians GDP shrank by 3.7 per cent in 2015 and that it is poised to shrink by up 1.9 per cent in 2016, before starting to grow again next year. However, the losses of these three years will not erase the cumulative gain in Russia’s power as a nation since 1999.

Looking forward, Russia faces a number of long-term challenges, including an obsolete and inefficient economic model, poor quality of governance, pervasive corruption, demographic fragility, instability in neighbouring countries and separatist threats to Russia itself.

We don’t know yet whether and when these challenges may acquire such an acute character that they may reverse the resurgence of Putin’s Russia described above. One thing is certain, however: Russia’s size, resources and military might all ensure that it remains a global player that will continue to affect the western world and the global order as a whole in profound ways for years to come, and should be treated accordingly.
