Hmd from Methanothermobacter marburgensis (mHmd) was found in a hexameric state, where an expanded oligomerization loop is detached from the dimer core and intrudes into the active site of a neighboring dimer. An aspartic acid residue from the loop ligates to FeII of the FeGP cofactor and ...
water, however, we are still unable to produce it at an affordable cost. The major problem is we are only able to produce hydrogen with a 70%-80% efficiency. This is due the complexity of water which, while ostensibly being a very simple molecule, is highly complex in the liquid state...

Spain is studying the Rover Environmental Monitoring Station, designed to survey the atmosphere and ultraviolet rays. Russia supplied the Dynamic Albedo of Neutrons instrument, which measures hydrogen below the surface of the planet, indicating water or ice. A suite of instruments called Sample ...
convened in Paris in February, 2007 to compare and advance climate research. The scientists determined that the Earth has warmed .6 degrees Celsius between 1901 and 2000. When the timeframe is advanced by five years, from 1906 to 2006, the scientists found that the temperature increase was ....
Hydrogen is a promising avenue for decarbonising energy systems and providing flexibility. In this paper, the JRC-EU-TIMES model – a bottom-up, technology-rich model of the EU28 energy system – is used to assess the role of hydrogen in a future decarbonised Europe under two climate sce...
Catherine Boeckmann loves nature, stargazing, and gardening so it’s not surprising that she and The Old Farmer’s Almanac found each other. She leads digital content for the Almanac website, and is also a certified master gardener in the state of Indiana.Read More from Catherine Boeckmann ...
(2,6-diaminopurine or Z) that has an additional amino group in position 2 compared to adenine13. The A:T base pair, with two hydrogen bonds, is therefore replaced by the Z:T base pair that has three hydrogen bonds, as in the G:C base pair (Fig.1). This feature, combined with ...
For example, hydrogen atoms have one electron orbiting the nucleus. Helium atoms have two electrons orbiting the nucleus. Aluminum atoms have 13 electrons circling the nucleus. Each atom has a preferred number of electrons zipping around its nucleus. Electrons circle the nucleus in fixed orbits --...
Efficient spin generation and manipulation require a large spin-orbit coupling (SOC), with GaAs a prototypical system, whereas long spin lifetimes (τs) is mostly found in weak SOC materials, such as graphene and diamond. Materials with large SOC as well as long τs are ideal for spintronic...
