A Toronto-based team is looking at environmentally-friendly ways to provide clean water.
In the same city, a research team is searching for high-strength lightweight materials that could replace common metals. With the help of an algorithm developed in South Korea the team successfully optimised a carbon material on the nanoscale.
The system arranged the carbon building blocks in new three-dimensionals structures making it five times stronger than titanium.
3D printed with a special technique, the prototype weighed the same as Styrofoam. Substituting one kilogram of titanium on planes with the material would reduce fuel consumption by 80 litres a year.
Bamboo serves as a steel alternative in buildings. Scrap metal, in turn, can even be consumed by some bacteria.
