Sulfonated graphene-induced hormesis is mediated through oxidative stress in the roots of maize seedlings.
TL;DR: The results indicate that SG induced a hormesis effect on plant height, i.e., low-concentration stimulation and high- Concentration inhibition, directly correlated with ROS levels in roots.

The rise of graphene
TL;DR: Owing to its unusual electronic spectrum, graphene has led to the emergence of a new paradigm of 'relativistic' condensed-matter physics, where quantum relativistic phenomena can now be mimicked and tested in table-top experiments.
