In Russia, created the first non-metallic metal

Scientists from Institute of Crystallography, Russian Academy of Sciences and Institute of Nuclear Research (Both — Russia) with financial support from the Carnegie Institution (USA) first discovered the conditions under which the nickel oxide becomes conductive metal ostoyanie.

Secure the emergence of metallic properties in oxide managed under incredibly high pressure, which almost 2.5 million times greater than atmospheric pressure (240 GPa). Report on the opening published in the journal Physical Review Letters.

Russian scientists have created the perfect gas sensor

A team of scientists from Moscow State University. MV Lomonosov Moscow State University and Research Center "Kurchatov Institute" has developed a gas sensor based on nanocrystalline indium oxide — a material that has long been used as a sensor that can determine the presence of nitrogen dioxide in the air. Electrical properties of these materials are directly dependent on the structure of the surface. If the surface of the indium oxide align molecules than oxygen molecules, it immediately changes the conductivity. In this study, researchers examined the effect of indium oxide nanocrystal size on its sensitivity to

RUSNANO and MBC invest in beryllium

RUSNANO and the "Corporation" MBC "invest in high-tech materials made of beryllium

"RUSNANO" and "Corporation" MBC "," announced the launch of investment a project to create a vertically integrated company full cycle of production and processing of beryllium. The total budget of the project will be about 7 billion rubles, including co-financing RUSNANO of 3.5 billion rubles.

Beryllium — a strategic metal required for the nuclear and aerospace industries and is used in the manufacture of telecommunications equipment. Currently available in beryllium Russia needs are met through imports. Products of the project company will be able

Leakage of nitric oxide in Togliatti. Video

Ecology

5.10.11.Nakanune at the plant "Kuibyshevazot" in the Motor City has leaked 97 kilograms oxide azota.Inzhenery company reported that it was because of process malfunction. And emphasizes that the release was short-lived.

Emergency services company promptly removed the violation. Formed as a result of leakage of evaporation to residential areas not reached, remaining within the industrial site. Currently, the neighboring businesses concentration of oxides of nitrogen is one milligram per cubic meter — it is 5 times lower than the maximum allowable level.

Why Mars is much more rusty than the Earth? As you know, in the surface layers of the red planet twice the iron oxide, although, according to experts, both bodies were formed from the same materials. David Ruby and his colleagues at the University of Bayreuth (Germany)

Established herbal solar battery

A researcher from the Massachusetts Institute of Technology (USA) Andreas Mershin developed solar panel from … agricultural waste such as grass clippings and fallen leaves. Hopes creator samoy "green" battery in the world in a few years it will be possible to mix the grass lawn in a bag with some cheap chemicals, attributed it all to the roof and immediately start receiving electricity.

If a little strain gyrus and try to remember secondary schools at the rate of biology, most certainly squeeze out here is the word: photosynthesis. The process by which plants convert sunlight into useful chemical energy.

Concentration of greenhouse gases in the atmosphere reached a record level

November 21.Amount of greenhouse gases in the Earth's atmosphere in 2010 reached record levels, and the rate of increase in their concentration increased, said on Monday the annual report of the World Meteorological Organization (WMO).

"The impact on greenhouse gas emissions from human activities have once again reached record levels since pre-industrial times," — said WMO Secretary-General Michel Jarraud.

"Even if we can stop today, our greenhouse gas emissions — and this is not the way — they will continue to persist in the atmosphere for decades to come and, therefore, continue to affect the delicate balance

The use of fertilizers is the reason for the increase in nitrogen oxide

According to researchers of the University of California Berkeley nitrogen fertilizers cause a sharp increase in the last 50 years in the atmosphere of the planet of nitric oxide, which is also on the list of greenhouse gases (the greenhouse activity of nitric oxide is almost 300 times higher than that of uglikslogo gas).

Their findings, American scientists are doing on the basis of the analysis of an isotope of nitrogen in Antarctic ice cores, as well as air monitoring data, which were collected from the 1978 monitoring station at Cape Grim in Tasmania.

Researchers found that since 1750 (the
