Hydrogen nano-clusters at low temperatures display 'superfluidity'—a quantum state of frictionless flow only previously observed in helium.

Hydrogen fuel-cell cars never quite promised a cross-country ... for his own personal use he has been drawn to the more ...

THE colour of the light which is emitted from the capillary of a vacuum tube containing pure hydrogen is the familiar vivid, deep pink, the prevailing tint being due to the predominating ...

Evans found that the 4686 series and the Pickering series can be obtained in a helium spectrum showing no trace of the ordinary hydrogen lines. These series were observed a few years ago by Prof.

capable of efficiently pairing with silicon for broader solar spectrum utilization." As part of their study, Sun and his colleagues applied their proposed hydrogen annealing method to a cadmium ...

Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the bright hydrogen emission lines. Key fact Line emission spectra are ...

Exadebit, present an initiative for flow measurement traceability for hydrogen in gas networks. To mitigate the most severe ...

They are distinguished from other SNe by the presence of hydrogen in their spectra. Based on the shape of their light curves, they are usually divided into Type IIL and Type IIP. Type IIL SNe show ...

Our work covers the full spectrum of hydrogen energy systems from production and compression to storage and utilization, with the aim to improve the cost-effectiveness of hydrogen energy use in our ...
