Graphene has attracted the interest of researchers in recent years because, despite its apparent anti-corrosive properties, its proximity was seen to increase the corrosion of copper. A research team from Chung-Ang University used Raman spectroscopy to analyse graphene’s properties over a long period and found that the corroded surface of copper forms a hybrid layer with graphene, which prevents further corrosion.

Autonomous vehicles watch the roads before them using inbuilt cameras. Ensuring that accurate camera orientation is maintained during driving is, therefore, key to letting these vehicles out on roads. Taking us one step closer to realising autonomous driving systems, scientists from Korea have developed a highly accurate and efficient camera orientation estimation method that will enable such vehicles to navigate safely across distances.
