Sentences with phrase «rather than hydrogen»

[Response: When methane is combusted, or if it reacts with oxygen in the atmosphere (a very slow type of combustion) the hydrogen in it produces water vapor, rather than hydrogen.

Another possible explanation for the strong radio signal Bowman and the EDGES team discovered is that there's more radio background radiation being absorbed, rather than the hydrogen gas being colder than previously thought.

Disks cool down more efficiently if their gas includes some molecular hydrogen — two hydrogen atoms bonded together — rather than atomic hydrogen, which consists of only one atom.

Krissansen - Totton explains in more detail: «Having methane and carbon dioxide together is unusual, because carbon dioxide is carbon's most oxidized state, and methane (composed of a carbon atom linked to four hydrogen atoms rather than any oxygen at all) is its least,» he says.

It's heavier than normal because each of the two hydrogen atoms in heavy H2O weighs two rather than one amu.

In a 2008 study, Haiman and his colleagues hypothesized that radiation from a massive neighboring galaxy could split molecular hydrogen into atomic hydrogen and cause the nascent black hole and its host galaxy to collapse rather than spawn new clusters of stars.

Think of the word «hydrogen» paired with «energy» rather than «bomb.»

Moreover, the production of hydrogen gas creates a layer that separates the sodium and the water, which should further slow the reaction, resulting in slow bubbling rather than a kaboom.

Hydrogen can also be split from water in high - temperature nuclear reactors or generated from fossil fuels such as coal or natural gas, with the resulting carbon dioxide captured and sequestered rather than released into the atmosphere.

PHWRs are similar to PWRs, but use raw uranium rather than enriched uranium oxide as fuel, and deploy heavy water — in which hydrogen is replaced by deuterium — as both moderator and coolant.

Other photographed objects have been too massive to be conclusively labeled planets, falling instead into the brown dwarf category (objects about eight to 80 Jupiters in size that lack sufficient mass to ignite hydrogen fusion in their cores, thereby never becoming true stars); have been found to themselves orbit brown dwarfs rather than stars; or have not been shown to be gravitationally bound to a star.

When the scientists tracked the pattern of emissions of a particular hydrogen molecule consisting of three hydrogen atoms (rather than the usual two), they expected to see a uniform planet - wide infrared glow.

Members of the PNNL - led hydrogen catalysis team will discuss developing catalysts using abundant metals rather than spendy ones such as platinum.

In doing so, as the CMB photons traveled through this hydrogen gas, it absorbed a particular frequency — so rather than look for a specific emission, astronomers have been looking for a specific type of absorption, or a certain frequency of CMB radiation that was missing.

Another innovative approach is to use cleaner - disinfectants with Accelerated Hydrogen Peroxide as the active ingredient rather than traditional «quat» or chlorine - based formulations.

Fueled by hydrogen, their electricity is generated on demand by a fuel cell rather than power from batteries.

Hydrogen - powered fuel - cell development programs fell off the automotive radar screen when the global economy faltered in 2008 and automakers focused on immediate survival rather than future products.

Meanwhile Toyota, the world's largest automaker and Korean giant Hyundai are placing long - term bets on hydrogen fuel cells, PHEVs and HEVs rather than pure EVs.

But a good chunk of humanity will survive, and wind up using fusion powered hydrogen ramjets to reach the stars, rather than the vanishing fossil fuels.

But until we get to those stages, improved energy storage schemes such as hydrogen, could be used to run other sources of electricity, such as nuclear and clean coal plants, as base - load (24 hours a day) rather than cyce to respond to demand requirements.

the oft favoured Hydrogen economy (rather a way of transporting energy than energy itself I know) must have a negative EROI.

Overall, it appears the country favours pure electric vehicles rather than hybrids or hydrogen fuel cell cars.

... Fusion Power... Generating electricity from fusion rather than fission of atoms has been a dream ever since the first hydrogen bomb was exploded.

They measure the hydrogen and oxygen isotopes to infer air temperatures at the time the snow fell, and the dust particles give a nice indication of the dusty periods (much of the dust was kicked up far away, in the Gobi Desert, rather than from sources closer to Greenland).

Although not combustible, the CO2 had to be flared rather than simply vented because it was mixed with hydrogen sulfide, which is often burned to convert it to safer compounds.

For example, the passage of the heliosphere through a cloud with a neutral hydrogen density of 11 cm − 3 rather than the present value of about 0.2 cm − 3 would shrink the termination shock from about 90 AU in the upwind direction to only 14 AU.»
