Credit: ACS Applied Energy Materials A new report by Skoltech scientists and their colleagues describes an organic material for the new generation of energy storage devices, which structure follows an elegant molecular design principle. It has recently been published in ACS Applied Energy Materials and made the cover of the journal. While the modern world relies on energy storage devices more and more heavily, it is becoming increasingly important to implement sustainable battery technologies that are friendlier to the environment, are easy to dispose, rely on abundant elements only, and are...

Graphene is an ultrathin material characterized by its ultrasmall bending modulus, superflimsiness. Now the researchers at the Nanoscience Center of the University of Jyväskylä have demonstrated how an experimental technique called optical forging can make graphene ultrastiff, increase its stiffness by several orders of magnitude. The research was published in Nature Partner Journals in May 2021.

Scientists at Empa and EPFL have identified a new type of defect as the most common source of disorder in on-surface synthesized graphene nanoribbons, a novel class of carbon-based materials that may prove extremely useful in next-generation electronic devices. The researchers identified the atomic structure of these so-called ''bite'' defects and investigated their effect on quantum electronic transport. These kinds of defective zigzag-edged nanoribbons may provide suitable platforms for certain applications in spintronics.

Researchers at the University of Arizona recently developed an innovative technique to capture the unused solar energy that illuminates a solar panel. As reported in the Journal of Photonics for Energy (JPE), they created special holograms that can be easily inserted into the solar panel package. This method can increase the amount of solar energy converted by the solar panel over the course of a year by about five percent.
