Researchers across the world have been trying to make such boron cousins of graphene. The technique developed by the research team at IIT Gandhinagar is not only inexpensive and simple in design, but also results in an aqueous colloid of these nanosheets, which means that a drop of water from this colloid would contain thousands of nanosheets swimming like micro-carpets.
By Converting Heat to focused Beams Of Light A New Solar Device Could Create Cheap And Continuous Power
The key step in creating the device was the development of something called an absorber-emitter. It essentially acts as a light funnel above the solar cells. The absorbing layer is built from solid black carbon nanotubes that capture all the energy in sunlight and convert most of it into heat.
3D printing has helped create things like complex art and yachts, but some of the most life-changing applications have been made in biotech, where the relatively cheap process makes implants and bionic limbs accessible to those who may not otherwise have them.
A group of scientists have turned graphene into a superconductor, capable of carrying electricity with no resistance. The secret involved sandwiching two layers of graphene together and offsetting them by a ‘magic angle.’ This discovery could help scientists trying to develop superconductors that work at room temperatures.
By employing a technique called scanning tunnelling microscopy lithography, the scientists are able to directly measure each atom’s wavefunction, thereby determining its exact location in the chip. “We are the only group in the world who can actually see where our qubits are,”
