Patterned graphene-based carbon sheet is a tunable semiconductor and traps carbon monoxide

A new atomically precise carbon sheet combines nanoporous graphene and biphenylene stripes, offering controlled ...

Most normal matter in the universe isn’t found in planets, stars or galaxies – an astronomer explains where it’s distributed

But the Big Bang theory predicts that about 5% of the universe’s contents should be atoms made of protons, neutrons and electrons. Most of those atoms cannot be found in stars and galaxies – a ...
