Graphene
-
Graphene is the Novak Djokovic of materials – it’s so damn talented that it’s getting boring celebrating each new victory. But an exciting new upstart is challenging graphene’s title. Meet goldene, a 2D sheet of gold with its own strange properties.

It slices, it dices, it's super strong and conductive, and now an ultra-pure form of ‘wonder material’ graphene has been inhaled during a human trial without affecting lung or cardiovascular function, opening the door to a novel drug delivery mode.
-
Thanks to our high demand for concrete, the world may eventually run out of accessible sand. Scientists at Rice University have now shown that substituting graphene can not only save sand, but makes concrete lighter, stronger and tougher.

With 2023 drawing to a close, it's once again time to look at the significant, intriguing, and sometimes just plain daft science stories of the year. So, let's dive in and see what the science types have been up to.
-
3D-printed concrete structures are claimed to be faster and cheaper to build than their traditional counterparts, but they're not always as strong. That problem may soon be solved by adding a pinch of graphene oxide, which could also be used to detect cracks.
-
Everybody’s favorite wonder material, graphene, continues to surprise. MIT physicists have discovered yet another brand new electronic state hiding in this overachieving little material – something they give the bizarre name of “ferro-valleytricity.”
-
Researchers have harvested hydrogen from waste plastics using a low-emissions method. They say it not only solves environmental problems, but the value of the graphene by-product could offset the costs of producing hydrogen.
-
Scientists at the University of Georgia have created a "superfoam" with two very valuable potential applications. It could be used not only to clean up oil spills, but also to keep infections from occurring at medical implant sites.
-
A team of researchers led by Northwestern University and the University of Texas at Austin (UT) have developed a novel graphene heart implant that’s about the thickness of a strand of hair and monitors and corrects abnormal heart rhythms using light.
-
Although it is possible to control devices using brain waves, doing so involves having electrodes and conductive gel applied to one's head. Now, however, scientists have developed a new type of "dry" electrode – and it's been used to control a robot.
-
When we think of graphene, we tend to think of its use in applications like electronics, medical devices and construction materials. Now, however, it's been incorporated into an additive which reportedly boosts the performance of humble plastic film.
-
Researchers have created cutting-edge graphene sensors to produce an interface that allows for accurate robotic control using thought alone. The development has positive implications for healthcare and a range of other industries.
