(Phys.org)—A large team of researchers from China, the U.S. and Japan has developed a more precise means for measuring the various band gaps in layered phosphorene, and in so doing, have found that it possesses advantages ...
(Phys.org)—Phosphorus is a necessary component of fertilizers needed for agriculture. In 2013 about 225 million tons of phosphate was extracted predominantly for fertilizer use. This rate could diminish the Earth's phosphorus ...
As scientists continue to hunt for a material that will make it possible to pack more transistors on a chip, new research from McGill University and Université de Montréal adds to evidence that black phosphorus could emerge ...

(Phys.org)—Aromatic molecules are a staple of organic chemistry. Aromatics, like benzene, have a unique pi-electron character that makes the ring structure exceptionally stable. While aromatics are typically reserved for ...
Phosphorus, a highly reactive element commonly found in match heads, tracer bullets, and fertilizers, can be turned into a stable crystalline form known as black phosphorus. In a new study, researchers from the University ...
