How Many Year U Need To Server In The Army
"More resources to the environment" for Italians topped the list
Ecobarometro According to the survey, 71.9% for the issue is a priority to work together. 75% blame the government for the lack of investment. Rejected the nuclear large majority in favor of clean energy and many have changed their lifestyle

The novelty is in second place. That in the first place in the concerns of the Italians there were no jobs - or rather unemployment - it was not difficult to predict. But the second place we find the environment. More than 7 out of 10 Italians are worried about pollution and waste of resources resulting from old choices, lack of courage and innovation. And when you go from general to particular, local protest focuses sull'arretratezza transport system in Italy penalizes rail transport for the benefit of road congestion.
And 'This is the picture that emerges from the survey, edited by Lorien Consulting and the monthly New Ecology, announced at the Forum held in Florence from QualEnergia Legambiente and Kyoto Club After the theme work (88.1 per cent of responses in a questionnaire in which they could tick up to three boxes) and the package of environmental problems which lies at an altitude of 71.9 percent, ranking the concerns of the Italians are the weakness of the political class (24.6 percent), terrorism and war (23 percent), institutional conflicts (14.5).
Ecobarometro thus marks the storm. It indicates those responsible. The 75.7 of respondents believe that the central government could do more to solve environmental problems. While the proceedings on local government, while still negative, is less severe: they are rejected by 61.5 per cent of responses.
The survey
then a great promise in the clean energy sources. The approval rating to first place the sun, followed by wind and hydroelectric. Nuclear failed: Only 30 percent of respondents are in favor, and drops to 25 percent if the perspective is that of a nuclear power in the region where you live. It is not just theoretical expectations and judgments. Many respondents have begun to do what they could. 98 percent use high-efficiency light bulbs, 96 percent have purchased a household appliance that reduces fuel consumption, 73 percent had taken a measure of insulation (isolation of walls with double glazed).

And before last, provocative poll question (having a million euro better to invest in a big car company like Fiat or help a new company in the renewable sector?) the 77 per cent of respondents opted for renewables.

Nobel Geim and Novoselov. They are the pioneers of graphene
Swedish Academy of Sciences has awarded the research "revolutionary" of the two Russian scholars of the thinnest material ever created in a lab that will revolutionize electronics. Two unique prize: a recent discovery and an award winning one of the youngest in history "What is our invention? Would be like asking what's the use plastic." The scientist Andre Geim has just won the Nobel Prize for Physics with his colleague Konstantin Novoselov, both from the University of Manchester. From Stockholm, which awards the prize committee's surprise call to give him the news and ask what will the graphene, the new material that they have invented. He is speechless. "I do not know. It 's like a piece of plastic to make a man a century ago and ask what you can do. A little bit' of everything, I think." Graphene has been described by the Nobel committee in Stockholm as " the first material in two dimensions'. It is in fact so thin as to have virtually eliminated the size of the thickness. To reach a height of an inch must be superimposed on three million sheets of graphene. Its "plot" consists of a single layer atoms of carbon and if it is visible as a large sheet of honeycomb cells. "Graphene is thin, strong, light and yet dense, almost transparent and flexible," said the Nobel committee in the grounds of his choice. E ' consists of a very common element - carbon, an essential block of living things - and it is a good conductor of electricity. To say what can serve as a material - described by the two Russian scientists in Science in October 2004 - the only limit is fantasia.Schermi thin, much smaller than today's computers, solar panels, tools to get you to explore its gorges in our DNA sensors capable of picking up even individual molecules of poisonous gases are just some of the ideas put forward since 2004. But perhaps the most appealing to our imagination is that of wearable electronic devices such as t-shirts. Being flexible and lightweight, the graphene can in fact be treated as a fabric. And his property to conduct electricity makes it attractive for computer gadgets and television industry. To get to their discovery and Konstantin Geim departed from a peak of pencil (made of graphite) and an adhesive tape. But next to a kit so simple, they had to put all their knowledge. A so small in fact the materials cease to behave with the ordinary laws of physics and start to follow those of quantum mechanics. And to make sheets of graphene are, however, tools and equipment that can operate in infinitely small. The "new plastic" So do not invade our world from one day to the next. Contrary to the habits of the Nobel committee in Stockholm, this award came just a few years after the discovery in 2004. And while Geim (born in Russia but a Dutch national) is 51, Novoselov (citizen Russian and English) with its 36 years is one of the youngest Nobel history. From the Swedish capital did not fail to mention the aspect of "playful" of the two winners of doing science. It is no coincidence that ten years ago, Geim also won an Ig Nobel. Given the anti-Nobel, these prizes are awarded by Harvard University to research the most funny, entertaining, seemingly unnecessary and ridiculous. Geim won for its "flying frog": a small amphibian that within a magnetic field rose into the air. ELENA

black silicon photovoltaic panels: a new target of research
A recent discovery of American scientists panels blacks are much cheaper and more efficient
As we know, unlike the white, which reflects the projected light, black absorbs it. This is the basic concept that started the team of researchers led by Howard Brenz, who said they had been involved in the project since late 2006 when he attended a lecture by a researcher at the Technical University of Monaco and has recently wanted to verify his intuition. The team is part of NREL, National Renewable Energy Laboratory, U.S., discovered that for this year has won the award for best innovation.
The idea was to blacken the common silicon wafer typically used for photovoltaic panels in order to absorb all the light not only avoiding wastage but also exploiting the weak radiation of early morning and dusk, in fact, increasing the efficiency and effectiveness of the panel. Specifically, through a low-cost technique developed at the University of Monaco, the silicon discs (wafers) was sprinkled with a mixture of acids because of their corrosive action, have affected millions of holes on the surface. These holes are able to capture the light, making the surface black. German scientists, thanks to an evaporation technique with vacuum pumps, with a mixture of hydrogen peroxide and hydrofluoric acid have sprinkled a thin layer of gold inside the wafer, all dark. Unlike the German colleagues, the NREL team has decided to optimize the technique: they have sprinkled the surface of silicon with a solution of gold nanoparticles in suspension, called "colloidal gold" and have waited until the water evaporates so that gold, then incidesse the wafer. Subsequently, the chemist of the NREL Vern Yost, wanting to improve technique, has decided to separate the nanoparticles with aqua regia, a mixture consisting of equally corrosive nitric acid and concentrated hydrochloric acid capable of dissolving metals such as gold and silver. Well, the water director reacted with gold to form a solution chloroauric acid, colloidal gold cheaper.

According to the American laboratory, so the absorption of light by the solar cells increased by 98% against 95% of the current ones. Result of some trivial goal, but enough to increase energy efficiency by 2% of the cell. Not only that, the creation of black silicon panels using the technique of NREL is not harmful to the environment because it produces less emissions than current panels.
