Graphene is already known for being incredibly strong, so how can it be made even stronger? By turning it into sheets of diamond, of course. Researchers in South Korea have developed a new method to convert graphene into ultrathin diamond films.

Inspired by the ocean’s role as a natural carbon sink, researchers at Ulsan National Institute of Science and Technology (UNIST) and Georgia Tech have developed a new system that absorbs CO2 and produces electricity and useable hydrogen fuel.

Clean and plentiful, hydrogen is a promising fuel source, but there are a few problems in the path to mainstream use. South Korean scientists have now developed a new system for producing hydrogen from water, which that they say overcomes some of these issues and produces the gas more efficiently.

Scientists at the Ulsan National Institute of Science and Technology have created a thermoelectric coating that can be directly painted onto almost any surface to capture waste heat and turn it directly into electricity.

Octopi are well-known for their grabby tentacles. Now, scientists have developed a material that mimics the sucker discs on those tentacles. It could be used for adhesive pads that are reversible, reusable, fast-acting, and effective even in wet conditions.
