Scientists have succeeded in developing a new and particularly efficient arrangement of components in a solar cell, where the charge donors are bundles of polymer (in green) and the charge acceptors are spherical carbon molecules, fullerenes (in purple and brown). [Courtesy of UCLA]

Can hydrogen be made to have the properties of graphene?

Molecules of carbon-60, also known as Becky balls, have been combined with amines to obtain a compound that absorbs carbon dioxide, which is a greenhouse gas, in an amount equal to a fifth of its weight. The material has the potential to be used as an environmentally friendly solution for carbon capture from emissions originating from natural gas wells and industrial plant chimneys.

The reaction of the nanoparticles to the light creates an electric field between the particles that increases the fluorescence and makes it possible to observe the single molecule.

In the sheet of the material graphene (the horizontal surface with the hexagonal pattern of carbon atoms) placed in a strong magnetic field, electrons can move along the edges, and are prevented from moving in the inner part of the sheet. In addition, in these languages, only the electrons with the appropriate spin will move in one direction only (the blue arrow), while the electrons with the opposite spin (the red arrow) are prevented from moving.

The method combines computed tomography (CT) - capable of providing "slices" of the XNUMXD structure (the circles) - together with X-rays that provide an image of the distribution of the particles within the structure (PDFs, visible in the graphs) in order to present the information regarding the nanoscale structure and chemistry ( the different colors) inside the material, pixel by pixel and in XNUMXD [courtesy of Columbia University].
