Breakthrough in single-photon integration

Researchers from Hebrew University of Jerusalem have successfully integrated single-photon sources onto tiny chips at room temperature using a hybrid metal-dielectric bullseye antenna. This innovation enables efficient back-excitation and front coupling of emission to optical fibers or low numerical aperture optics, promising advanceme...

Researchers: Energy-efficient construction materials work better in colder climates

The study reveals that phase change materials (PCMs) can store and release large amounts of energy, providing a cooling effect in winter and a warming effect in summer. In colder climates, the energy payback period of using PCMs is the shortest, with annual energy savings ranging from 0.24 to 29.84 kWh/m2a.
