such as hydrogen, oxygen, carbon and nitrogen in samples.
As hydrogen fuel cell vehicles continue to roll out in increasing numbers, the infrastructure for fueling them must expand as well.
Second, it needs the right ingredients: a substantial collection of molecules such
as hydrogen peroxide or sulfur dioxide, which play vital roles in the chemical reactions that form the foundation of life.
This process produces a mixture of gases — primarily methane, some carbon dioxide and tiny portions of other gases such
as hydrogen sulfide.
That is important not only for the design of dye - sensitised solar cells, but also in order to be able to develop systems of materials for photocatalytic generation of hydrogen for storing solar
energy as hydrogen fuel.»
These human - made materials were introduced in the 1990s, and researchers around the world are working on ways to use them as molecular sponges for applications such
as hydrogen storage, carbon sequestration, or photovoltaics.
The key, it seems, lies in the interaction between the bonds that hold the atoms in the water molecule together and the much weaker bonds, known
as hydrogen bonds, that are the glue holding groups of water molecules together.
The project also improves the air quality in the region by reducing the amount of pollutants emissions contained in the landfill gas such
as hydrogen sulphide which an cause nausea, delirium, headaches, and skin and eye irritation.
While the number of FCVs available to offtake hydrogen remains low, European countries are keenly exploring the opportunity to store renewably generated electricity
as hydrogen in the existing natural gas pipeline.
@evi: They study I linked gave distributed costs as well
as hydrogen production costs locally, in particular for hydrogen from biomass and electrolysis.
But Wright doubts such a weapon, also known
as a hydrogen bomb, will be miniaturized into a missile - ready warhead by North Korea anytime soon.
Under similar pressures but higher temperatures, it has been suggested that ice X could possibly transform into a phase of ice that can conduct
electricity as hydrogen atoms move freely around the oxygen lattice.
They could also store up to 1.7 % of their
weight as hydrogen, about as much as carbon nanotubes could store.
All three electrodes connect to a single solar cell that serves as the device's power source, and the electrical energy harvested by the solar cell can be stored in one of two ways: electrochemically in the supercapacitor or
chemically as hydrogen.
Degassing of ash erupted during 1976 by Augustine Volcano in Alaska released 525 x 106 kg of chlorine (± 40 %), of which 82 x 106 to 175 x 106 kg may have been ejected into the stratosphere
as hydrogen chloride [HCl].
Using sunlight to create fuels (such
as hydrogen on the other electrode in this solar cell) with inexpensively prepared electrodes may provide a solution to the intermittency drawback of solar energy.
Receptors bearing reactive functional groups may act as molecular reagents or catalysts, performing a chemical transformation on the bound substrates (by such
reactions as hydrogen transfer, ester cleavage, and protoadenosinetriphosphatase and protokinase activities).
Later in the day, an explosion occurred at the reactor,
as hydrogen produced from water vapour detonated.
This world is of a feminine gender but the elemental gods such
as hydrogen oxygen, etc are of a hermaphrodiatic gendership.
Superconducting cables minimize energy loss, and power - to - gas systems store excess electrical
generation as hydrogen or methane.
The exotic particles, the lightest of which would be at least 100 times as
heavy as a hydrogen atom, are referred to as weakly interacting massive particles, or WIMPs.
Electricity from renewable sources such as solar and wind power, which can be intermittent and unreliable, could then be easily stored and
distributed as hydrogen fuel.
In fusion, the nuclei of light elements such
as hydrogen fuse together to make heavier elements.
It is bound by the electric attraction between positron and electron,
just as the hydrogen atom is bound by the attraction between the proton and the electron.
If there were too much UV light, no water could survive on the surface because the water molecules would break up and escape through the top of the
atmosphere as hydrogen and oxygen gas.
Chemically, muonium behaves like a hydrogen isotope, but it's nine times as
light as hydrogen.
Under such conditions, the carbon atoms of the CFCs ended up as carbon monoxide and carbon dioxide, the chlorine atoms as ethyl chloride, and the fluorine atoms
as hydrogen fluoride.
At the beginning of their
lives as hydrogen - burning objects, stars define a nearly unique line in the Hertzsprung - Russell diagram called the zero - age main sequence.
