Compact amplifier could revolutionize optical communication
Researchers at Chalmers University of Technology, Sweden, present a unique optical amplifier that is expected to revolutionise both space and fiber communication. The new amplifier offers high performance, is compact enough to integrate into a chip just millimeters in size, and — crucially — does not generate excess noise. “This could be compared to switching […]
Janus graphene opens doors to sustainable sodium-ion batteries
In the search for sustainable energy storage, researchers at Chalmers University of Technology, Sweden, present a new concept to fabricate high-performance electrode materials for sodium batteries. It is based on a novel type of graphene to store one of the world’s most common and cheap metal ions — sodium. The results show that the capacity […]
