An important step towards next-generation ultra-compact photonic and optoelectronic devices has been taken with the realization of a two-dimensional excitonic laser. Scientists embedded a monolayer of tungsten disulfide into a special microdisk resonator to achieve bright excitonic lasing at visible light wavelengths.
Protease inhibitors are a class of antiviral drugs that are commonly used to treat HIV, the virus that causes AIDS. Scientists designed a new delivery system for these drugs that rid immune cells of HIV and kept the virus in check for long periods.
Scientists explored the fundamental physics of the world's best thermoelectric material - tin selenide - using neutron scattering and computer simulations. Their new understanding of the origin of atomic dynamics in this material may aid research in energy sustainability and enable the design of materials that efficiently convert heat into electricity.
