High-power nanocarbon supercapacitors made with laser techniques

Researchers at the Institute of Materials Science of Barcelona (ICMAB-CSIC) have developed two innovative laser technologies to produce hybrid nanocarbon electrodes for high-power supercapacitors. These supercapacitors not only charge and discharge electrical energy quickly, but also store more energy than those normally used.

Ultrabroad band light absorption material with a high photothermic conversion

Researchers from the CSIC and the ICN2 have developed a flexible metamaterial that has an ultrabroadband optical absorption range and a high photothermal conversion efficiency. It transforms into heat the 84% of the absorbed light on average. With applications on energy, it can be easily fixed on flat and curved surfaces.

New method to obtain nanostructures with previously impossible geometries

Scientists at the CSIC and the Porto University have developed a method for obtaining nanostructures of diverse ferromagnetic materials, which can be applied to magnetic, nanophotonic and magnonic devices. The new procedure avoids the standard lithographic techniques, and shortens production time and economic cost.
