Debut of the Alstom Coradia iLint, a hydrogen-powered passenger train, at InnoTrans 2016. In transportation, the original (2003) generic term "hydrail" includes hydrogen trains, zero-emission multiple units, or ZEMUs — generic terms describing rail vehicles, large or small, which use on-board hydrogen fuel as a source of energy to power the traction motors, or the auxiliaries, or both.
A star blows itself apart in a nearby galaxy, and astronomers scramble to study the rare appearance of a supernova. NOVA kicks off its 15th season with a fast-breaking science story as it is happening. Including scenes taken from Las Campanas Observatory in Chile and many others in the U.S., Australia and South Africa. Narrated by Bill Mason.
When Mayor Humdinger and his cousin the Cheetah steal the other racers' race cars and cheat during the race, causing the Whoosh to injure himself, Ryder and the PAW Patrol become the race car pit crew to solve the case, while Marshall takes the Whoosh's place of winning the race. 3. "Jet to the Rescue". Louise Moon.
Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H2, sometimes called dihydrogen, [11] but more commonly called hydrogen gas, molecular hydrogen or simply hydrogen. It is colorless, odorless, [12] non-toxic, and highly ...
In this process, hydrogen is produced from a chemical reaction between steam and methane, the main component of natural gas. Producing one tonne of hydrogen through this process emits 6.6–9.3 tonnes of carbon dioxide. [4] When carbon capture and storage is used to remove a large fraction of these emissions, the product is known as blue hydrogen.
Dirty Vegas are an English house music group initially made up of Ben Harris and Paul Harris (no relation) on instruments and production and Steve Smith on vocals. The group formed in 2001, then broke up in 2005 before reforming in December 2008 to record new material. They are best known for their international hit single " Days Go By ", which ...
e. Hydrogen embrittlement (HE), also known as hydrogen-assisted cracking or hydrogen-induced cracking (HIC), is a reduction in the ductility of a metal due to absorbed hydrogen. Hydrogen atoms are small and can permeate solid metals. Once absorbed, hydrogen lowers the stress required for cracks in the metal to initiate and propagate, resulting ...
Contents. Hydrogen spectral series. The spectral series of hydrogen, on a logarithmic scale. The emission spectrum of atomic hydrogen has been divided into a number of spectral series, with wavelengths given by the Rydberg formula. These observed spectral lines are due to the electron making transitions between two energy levels in an atom.
