IN 1896 Prof. E. C. Pickering discovered a series of lines in the spectrum of the star ζ Puppis which has been attributed to hydrogen in consequence of numerical relationship to the Balmer series ...

WHILE making experiments on the apparent production of neon and helium during electric discharges, I have noticed an effect which may be of interest to spectroscopists. A powerful oscillatory ...

Green hydrogen has long been billed as the clean fuel that could decarbonize heavy industry, shipping, and long‑distance ...

Astrophysicists can now analyze the vast molecular clouds of gas and dust where stars are born more accurately. New research has solved equations of quantum mechanics to describe more precisely the ...

Twelve colors and counting. The terminology associated with hydrogen—specifically, the use of color descriptors such as green, blue and gray—has become widespread in discussions about renewable energy ...

A novel dye-sensitized photocatalyst developed at Science Tokyo enables the capture of long-wavelength visible light for ...

Taken from the March 2022 issue of Physics World, where it appeared under the headline "The woman who found hydrogen in the stars". Sidney Perkowitz delves into the work and life of Cecilia ...

Hydrogen is considered a key energy source that is becoming increasingly popular in today’s energy-conscious world. It must be in liquid form for both transport and use. At 298 K, molecular hydrogen ...

A University of Delaware-led research team reports an advance in the June 1 issue of Science that may help astrophysicists more accurately analyze the vast molecular clouds of gas and dust where stars ...

Green hydrogen is made by using clean electricity from renewable energy technologies to electrolyse water (H2O), separating the hydrogen atom within it from its molecular twin oxygen. The Russian ...
