Under Anderson, Wired has produced some widely noted articles, including the April 2003 " Welcome to the Hydrogen Economy " story, the November 2003 " Open Source Everywhere " issue ( which put Linus Torvalds on the cover and articulated the idea that the open source method was taking off outside of software, including encyclopedias as evidenced by Wikipedia ), the February 2004 " Kiss Your Cubicle Goodbye " issue ( which presented the outsourcing issue from both American and Indian perspectives ), and an October 2004 article by Chris Anderson, which coined the popular term " Long Tail.

Hydrogen bonds exist between water molecules, causing them to line up ; as the molecules at the top of the plant evaporate, each pulls the next one up to replace it, which in turn pulls on the next one in line.

Hydrogen then reacts with oxygen gas on a palladium catalyst to produce more water, thereby removing oxygen gas.

Hydrogen sulfides and sulfides react with copper to form various copper sulfides on the surface.

Hydrogen use would require the alteration of industry and transport on a scale never seen before in history.

Another perspective on the problems that companies seeking to commercialize Hydrogen fuel cell technology have faced, is that the technology would only be economical in a regulatory regime that imposed a significant price on fossil-fuel-generated carbon emissions, with a goal of effectively reducing such emissions and slowing global warming trends.

Although hydrogen sulphide is toxic in high concentrations, the amount present in kala namak used in food is small and thus its effects on health are negligible: Hydrogen sulphide is also one of the components of the odor of rotten eggs and boiled milk

At the 2004 North American International Auto Show, Mazda unveiled the RX-8 Hydrogen RE concept car, designed to run on either hydrogen or gasoline.

The second paper, " Power from Space and the Hydrogen Economy ," discussed the implications of the recent discovery of vast deposits of methane hydrates under Arctic permafrost and on continental shelves, which may be sufficient to meet all world energy needs for many thousands of years.

While at Berkley, Bhutto witnessed the public panic when the Soviet Union first exploded the bomb, codename First Lightening in 1949, prompting the U. S. government to famously launch the research on Hydrogen bombs.

Hydrogen peroxide is primary irritant and the contact of the liquid solution with skin will cause bleaching or ulceration depending on the concentration and contact time.

The evidence available suggests that products based on Accelerated Hydrogen Peroxide, apart from being good germicides, are safer for humans and benign to the environment.

Unst is also home to the Promoting Unst Renewable Energy ( PURE ) Wind Hydrogen project, a community-owned clean energy system based on hydrogen production.

Notable remixers featured on the various releases of the single include Above & Beyond, Rank 1, Hydrogen Rockers ( an alias of Dirty Vegas ), and Peter Luts ( of Ian Van Dahl and Lasgo ).

* Hydrogen atoms on carbon are implicit.

After releasing the albums Burn Out At The Hydrogen Bar and East Side Militia on Fifth Colvmn Records, Chemlab broke up in 1997 and then reformed in 2004 to release an album entitled Oxidizer with Jared as the only original member.

Hydrogen would then be reacted with carbon dioxide in Sabatier process, producing methane and water.

Hydrogen is used for the creation of ammonia for fertilizer via the Haber process, and converting heavy petroleum sources to lighter fractions via hydrocracking.

" Hydrogen burning " is an expression that astronomers sometimes use for the stellar process that results in the nuclear fusion of four protons to form a nucleus of helium-4.

Hydrogen burning in chlorine produces a flame and in the process emits gaseous hydrogen chloride ( HCl ) as the combustion product.

The DIAMEX ( DIAMideEXtraction ) process has the advantage of avoiding the formation of organic waste which contains elements other than Carbon, Hydrogen, Nitrogen, and Oxygen.

Hydrogen peroxide / kerosene fuelled engines such as the British Gamma of the 1950s used a closed-cycle process ( arguably not staged combustion, but that's mostly a question of semantics ) by catalytically decomposing the peroxide to drive turbines before combustion with the kerosene in the combustion chamber proper.

Hydrogen bromide ( HBr ) also takes this pathway, but sometimes a radical process competes and a mixture of isomers may form.

Hydrogen gas must be distinguished as " technical-grade " ( five times pure ), which is suitable for applications such as fuel cells, and " commercial-grade ", which has carbon-and sulfur-containing impurities, but which can be produced by the much cheaper steam-reformation process.

Hydrogen embrittlement is the process by which various metals, most importantly high-strength steel, become brittle and fracture following exposure to hydrogen.

Other mechanisms of introduction of hydrogen into metal are galvanic corrosion, chemical reactions of metal with acids, or with other chemicals ( notably hydrogen sulfide in sulfide stress cracking, or SSC, a process of importance for the oil and gas industries ).< ref >< span class =" plainlinks "> ASTM F1940-07a Hydrogen Project </ span ></ ref >

Hydrogen introduced to the silicon during the synthesis process is well known to replace dangling bonds, as are other elements such as oxygen.

Hydrogen peroxide / kerosene fuelled engines such as the British Gamma of the 1950s may use a closed-cycle process ( arguably not staged combustion, but that's mostly a question of semantics ) by catalytically decomposing the peroxide to drive turbines before combustion with the kerosene in the combustion chamber proper.

Hydrogen peroxide is also generated for phagocytes in a process often referred to as a respiratory burst.

Hydrogen gas can also be used to extract oxygen from the lunar regolith, although the process is not very efficient.

In the case of quantum mechanics, the main part of the three-body problem refers to the finding the eigenstates and their energies .. For a special case of the quantum three-body problem known as the Hydrogen Molecular ion, the eigenenergies are solvable analytically ( see discussion in quantum mechanical version of Euler's three-body problem ) in terms a generalization of the Lambert W function.

Some special cases of three-body systems are amenable to analytical solutions ( or nearly so )-by special treatments-such as the Hydrogen molecular ion whose eigenenergies can be given in terms of a generalized Lambert W function or the Helium atom which has been solved very precisely using basis sets of Hylleraas or Frankowski-Pekeris functions ( see references of the work of G.
