TL;DR: In this article, the authors investigated the superalkali decorating on graphene and the hydrogen storage properties by using first principles calculations, and the results showed that the NLi4 units can be stably anchored on graphene while the Li atoms are strongly bound together in the super-alkali clusters.

TL;DR: In this article, the authors decorate h-BN using superalkali NLi4 and investigate the hydrogen storage properties by density functional theory, which shows that the H2 molecules adsorbed on the bottom Li+ cations are strongly polarized due to the small radius of Li+, and the H 2 molecules attached to the top Li+ are adsorbated by feeding back the excess electron up to the antibonding σ* orbitals of the h2 molecules.

TL;DR: The role of selenium (Se) or phosphorus (P) in regulating the As contamination of rice plants has been reported in some studies, but the combined impacts of Se and P on the fate of As and the underlying mechanisms are poorly understood as mentioned in this paper .

TL;DR: In this paper , a database of heavy metal content in a vegetable-soil system in China was constructed through literature review and field sample collection, and a systematic analysis of seven heavy metal contents in edible parts of vegetables and their bioaccumulation capacity among different vegetables was also performed.
