Flexible metasurface computer solves complex equations at near light-speed
Jan 12, 2024 (Nanowerk Spotlight) As our digital devices handle increasingly complex computations, scientists have looked to physics for inspiration on new computing paradigms. Rather than shuttling electrical signals across silicon like conventional processors, an intriguing approach encodes information in electromagnetic or acoustic waves propagating through space. These wave-based computers...
A stepping stone to study superconductivity
Jan 12, 2024 (Nanowerk News) RIKEN physicists have found an ideal platform for exploring the behavior of electrons in a material as it approaches superconductivity (Physical Review B, "Pure nematic state in the iron-based superconductor FeSe"). This could help to develop new superconductors that operate at more convenient temperatures than...
Integrating dimensions to get more out of Moore’s Law and advance electronics
Jan 12, 2024 (Nanowerk News) Moore's Law, a fundamental scaling principle for electronic devices, forecasts that the number of transistors on a chip will double every two years, ensuring more computing power — but a limit exists. Today's most advanced chips house nearly 50 billion transistors within a space no...
Catalytic combo converts CO2 to solid carbon nanofibers
Jan 11, 2024 (Nanowerk News) Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and Columbia University have developed a way to convert carbon dioxide (CO2), a potent greenhouse gas, into carbon nanofibers, materials with a wide range of unique properties and many potential long-term uses. Their strategy...
Graphene-based neurotechnology paves way for high-precision therapeutic applications
Jan 11, 2024 (Nanowerk News) Following years of research under the European Graphene Flagship project, ICN2 spearheaded in collaboration with the University of Manchester the development of EGNITE (Engineered Graphene for Neural Interfaces), a novel class of flexible, high-resolution, high-precision graphene-based implantable neurotechnology. The results, published in Nature Neurotechnology ("Nanoporous...
AI breakthrough creates images from nothing
Jan 11, 2024 (Nanowerk News) A new, potentially revolutionary artificial intelligence framework called “Blackout Diffusion” generates images from a completely empty picture, meaning that the machine-learning algorithm, unlike other generative diffusion models, does not require initiating a “random seed” to get started. Blackout Diffusion, presented at the recent International Conference...
