This material is designed with 2D technology because it is very thin
Graphene has a number of amazing properties. It has recently become a semiconductor material, and they have also discovered ways to combine it with diamond to create an amazing material. However, in a turn of events, they have developed an even more surprising technology that relies not so much on graphene as on another material, specifically a metal extremely precious over thousands of years of history: gold.
The article that It was recently published in Nature Synthesis They explain how they did it, which is really surprising, and this new material has a quite evocative name: Goldini In clear reference to graphene. Let's see what its characteristics are and why it is quite futuristic.
Goldinithe new metal that could outperform graphene
For the first time, a team of scientists has created… Single atom thick gold flakes. This is a truly surprising achievement for the experts who named it, Golden, i.e. Goldino in clear reference to graphene. Researchers at Linköping University in Sweden believe it could be a very useful technology in converting carbon dioxide and producing hydrogen, as well as in the manufacture of very valuable chemicals. Thus, it could open up a whole new set of really useful applications that could help different industries take off once and for all, as is the case with green hydrogen production. Whatever it is, it's gold It becomes a semiconductorSo that it can compete with graphene.
So far, previous attempts to create gold sheets one atom thick have failed. Gold tends to clump together, which makes it really difficult to achieve this goal. However, by studying the methods of Japanese blacksmiths they were able to do this. To manufacture this material, they used a 3D base where the gold was embedded between layers of titanium and carbon, thus ensuring that it did not clump together easily. We add to this mix Murakami detector Which is used in Japanese blacksmithing to remove carbon residue and change the color of steel.
All this is done in complete darkness to prevent cyanide formation Gold melts. Furthermore, the discovery was relatively accidental, as they were working on other applications for gold and other materials, but when they saw that it had been achieved they focused their efforts on it.
The resulting gold is So good that it has not three dimensions, but twoIt has some interesting potential applications, especially in studying graphene and water purification. In addition, it can also be used for new Internet networks and other advanced communications. Therefore, they want to apply these developments to other noble metals to see if they could have other uses that would help advance research in other fields.
