- Subsurface nanometrology: Probing hidden materials via atomic force microscopy 07/09/2023 A new nanoscience study led by a researcher at the Department of Energy's Oak Ridge National Laboratory takes a big-picture look at how scientists study materials at the smallest scales.
- Magnonic computing: Faster spin waves could make novel computing systems possible 05/09/2023 Research is underway around the world to find alternatives to our current electronic computing technology, as great, electron-based systems have limitations. A new way of transmitting information is emerging from the field of magnonics: instead of electron exchange, the waves generated in magnetic media could be used for transmission, but magnonics-based computing has been (too) slow to date. Scientists have now discovered a significant new method: When the intensity is increased, the spin waves become shorter and faster -- another step towards magnon computing.
- Washable, transparent, and flexible OLED with MXene nanotechnology? 24/08/2023 Transparent and flexible displays, which have received a lot of attention in various fields including automobile displays, bio-healthcare, military, and fashion, are in fact known to break easily when experiencing small deformations. To solve this problem, active research is being conducted on many transparent and flexible conductive materials such as carbon nanotubes, graphene, silver nanowires, and conductive polymers.
- Observing microscopic transformations of electrocatalyst surfaces 22/08/2023 Developing technologies that can convert CO2 into synthetic fuels and base chemicals is of key importance for reaching climate goals. The electrochemical reduction of CO2 at copper electrodes using electric power from renewable sources could be used for the production of e-fuels. New studies show that this process changes the arrangement of the copper atoms at the catalyst surface.
- Team develops solvent- and hydrogen-free method to upcycle high-density polyethylene plastics 20/08/2023 A research team led by Prof. Zeng Jie from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), has made a significant breakthrough in the field of plastic upcycling.
- Three simple steps to make the longest graphene nanoribbon ever 17/08/2023 A Lego-like synthesis previously produced record-breaking nanoribbons of 30, then 53 fused rings. Now, a similar ‘accelerated’ modular methodology made a molecular nanoribbon that is triple the longest ever made – in just three simple steps. The gargantuan graphene nanoribbon is almost 36nm long, featuring 147 linearly linked rings and a conjugated core of 920 atoms. The first experiments, although preliminary, promise great applications in electronics and optoelectronics, thanks to fluorescence features that outperform state-of-the-art quantum dots.

- Photonic time crystals could open the door to a new branch of optics 08/08/2023 Refractive index—the ratio of the speed of electromagnetic radiation in a medium to its speed in a vacuum—can be modulated fast enough to generate photonic time crystals (PTCs) in the near-visible part of the spectrum, a new study published in the journal Nanophotonics demonstrates. The study's authors suggest that the ability to sustain PTCs in the optical domain could have profound implications for the science of light, enabling truly disruptive applications in the future.
