One of the persistent mysteries about our Universe is the extreme imbalance between matter and antimatter. Antimatter and matter were both generated during the Big Bang, but the Universe is now ...

Antimatter is matter that we don’t encounter very much in everyday life. This form of matter is different to the stuff we see around us. In simple terms, antimatter is matter that carries an opposite ...

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 ...

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 ...

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

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 ...

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 ...

Sharing a long history, the energy industry and hydrogen technology have experienced remarkable growth in recent times. Hydrogen, the most abundant element in the universe, is proving its value as a ...
