Researchers in Zurich have reproduced Michelangelo’s David as a miniature in metal

02-Jan-2020

There he is, standing upon his pedestal: David by Michelangelo. A world-​famous statue that nearly every child can recognise. But this David is just 1 millimeter tall, pedestal included, and is made not of marble like the 5.17-​meter original, but of pure copper. It was created using 3D printing ...

The use of potassium bromide in the production of graphene on a copper surface can lead to better results. When potassium bromide molecules arrange themselves between graphene and copper, it results in electronic decoupling. This alters the electrical properties of the graphene produced, bringing ...

How protein fragments can be used for the recycling of electronics waste

17-Oct-2018

Without important key elements such as copper or rare earth metals, the electronics industry would grind to a halt and electricity would cease to flow. End-of-life products like discarded energy-saving lamps, mobile phones and computers could provide an important secondary source for these ...
