An international team of researchers has demonstrated a new way to increase the robustness and energy storage capability of a particular class of lithium-rich cathode materials - by using a carbon dioxide-based gas mixture to create oxygen vacancies at the material's surface.
Innovative technology has been able to find and facilitate the killing of cancer cells in mice without harming the nearby healthy tissue. A treatment using this technology in humans could reduce the rate of cancer recurrence or metastasis.
In a step that could bring perovskite crystals closer to use in the burgeoning solar power industry, researchers have tweaked their crystal production method and developed a new type of two-dimensional layered perovskite with outstanding stability and more than triple the material's previous power conversion efficiency.
As an important step towards graphene integration in silicon photonics, researchers have published a paper which shows how graphene can provide a simple solution for silicon photodetection in the telecommunication wavelengths.
Researchers have been able to quantify fundamental physical limitations on the performance of cloaking devices, a technology that allows objects to become invisible or undetectable to electromagnetic waves including radio waves, microwaves, infrared and visible light.
