Chemistry, Biochemistry of Nanoparticles, and Their Role in Antioxidant Defense System in Plants
TL;DR: In this article, the authors discuss the effects of ENPs on photosystems and the mechanisms of generation/scavenging of reactive oxygen species (ROS) in higher plants, including catalase (CAT), guaiacol peroxidase (GPOX), ascorbate peroxide (APOX), superoxide dismutase (SOD), glutathione reductase (GR), and dehydroascorbate reductases (DHAR) are discussed.

TL;DR: After scrutinizing the most recent literature, it seems that the divergence in the research results may be possibly attributed to multiple factors such as ENM properties, plant species, soil dynamics, and soil microbial community.

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.
