Boron can enhance mechanical properties of steel, but too much boron will segregate from the steel and negate these benefits. Researchers led by Wuhan University of Science and Technology looked to enhance the toughness of high boron steel using a novel processing technique called quenching and partitioning.

Graphene nanoribbons are a family of carbon allotropes that exhibit semiconducting properties promising for electronic applications. However, the conventional bottom-up synthesis method for graphene nanoribbons is a costly and low-yield process. Researchers led by the Moscow Institute of Physics and Technology developed an alternative method that is higher yield and lower cost.
