50 years of Science in CERN

What is CERN Large Hadron Collider (LHC) ?

Unravel the remaining mysteries of the universe

The Large Hadron Collider atom smasher, or the LHC, a 17-mile circular tunnel situated 100 metres underground near Geneva, is the biggest experiment ever.
Located at CERN, the European Centre for Nuclear Research, it is the most powerful in a series of particle accelerators that, over the last 70 years, have allowed us to penetrate deeper into the heart of matter.
It recreate conditions not seen since the big bang of creation to probe the secrets of the cosmos.

Natural gas instead of Gasoline, Which country move fast?

Fuel rationing has forced Iran's car makers to scale down the manufacture of gasoline powered cars and increase production of dual-fuel cars that also run on natural gas as part of Iranian government's attempt to reduce billions of dollars it spends each year to import gasoline.

In the ad. Boone talks about how the Iranians are moving quickly to vehicles powered by Natural gas so they can free up their $120 a barrel oil to sell to us. Boone says:
“Get this one. Iran is changing its cars to run on natural gas and we’re not doing a thing here…”
Please let have a look on this video:

Newsweek : Most of the grads of Iranian universities were working with major international companies

One of the best universities of the world is in Iran, the Newsweek weekly said in its latest edition, referring to Iran’s Sharif University of Science and Technology. “Forget Harvard _ one of the world’s best undergraduate colleges is in Iran,” said the news weekly in an article appeared in its August 9 edition. It said that Sharif University has now one of the best undergraduate electrical-engineering programs in the world. “In 2003, administrators at Stanford University’s Electrical Engineering Department were startled when a group of foreign students aced the notoriously difficult Ph.D. entrance exam, getting some of the highest scores ever. “That the whiz kids weren’t American wasn’t odd; students from Asia and elsewhere excel in US programs. The surprising thing, say Stanford administrators, is that the majority came from one country and one school: the Sharif University of Science and Technology in Iran.” Newsweek quoted Bruce A. Wooley, a former chair of the Electrical Engineering Department, as saying, “Stanford has become a favorite destination of Sharif grads.” Noting that Iranian students are developing “an international reputation as science superstars,” the weekly added. “Iranian students from Sharif and other top schools, such as the University of Tehran and the Isfahan University of Technology, have also become major players in the international Science Olympics, taking home trophies in physics, mathematics, chemistry and robotics.” According to the news magazine most of the grads of Iranian universities were working with major international companies. “The Silicon Valley companies from Google to Yahoo now employ hundreds of Iranian grads, as do research institutes throughout the West. Olympiad winners are especially attractive; according to the Iranian press, up to 90 percent of them now leave the country for graduate school or work abroad.”

Bandgap Engineering

TiO2 is of great interest in the field of heterogeneous photocatalysis. TiO2 has the advantage of being cheap, nontoxic, and stable, all of which make it attractive for remediation of environmental organic pollutants. However, its wide bandgap (3.2 eV) means that is can only utilize just ~5% of the solar spectrum, all in the UV region. If this threshold energy could be reduced, visible light could then be used, opening up a much larger portion of the solar spectrum for potential photocatalytic work.
A large number of approaches have been taken to reduce the bandgap energy of TiO2, such as doping with transition metal cations, creating oxygen vacancies, or, most recently, doping with anions such as C, S, and N. The first report of N-TiO2 was by Asahi et al. in 2001, in which they bleached methylene blue (MB).
It was originally believed that mixing of nitrogen 2p states with lattice oxygen 2p states led to an overall reduction in the bandgap energy. However, more recent studies have shown both theoretically and experimentally that either substitutionally or interstitially bound nitrogen species result in localized N 2p states above the valence band.
