Single-atom catalysts (SACs) have emerged as a new frontier in heterogeneous catalysis, and demonstrated distinguishing performances for various reactions due to their high catalytic activity with a significantly reduced amount of metals used. However, the catalytic performance of SACs for nitrogen fixation and conversion has been rarely explored. Scientists now have proposed a quite promising single-atom-based electrocatalyst for N2 reduction to NH3 under ambient conditions.
There are too many high-energy positrons in the cosmic rays reaching the Earth. These positrons could be being produced by pulsars in our vicinity. The most recent measurements have practically excluded this possibility, strengthening the competing and much more exotic hypothesis concerning the origin of the excess positrons.
The team’s calculations indicate a spin lifetime anisotropy that is orders of magnitude larger than anything observed in graphene until now.
As a result of this breakthrough, it is now possible to observe the behavior of the water produced in fuel cells for automobiles which often experience drastic changes in reactions.
