More Evidence Hybrid Immunity Confers Highest Level of COVID Protection
Hybrid immunity from a COVID-19 infection plus a vaccine provided an immune boost against symptomatic disease, as well as severe outcomes, Brazilian researchers found. Among people who survived a COVID infection from Feb. 24, 2020 to Nov. 11, 2021, vaccine effectiveness against symptomatic disease at least 14 days after series completion was 44.0% (95% CI […]
Two-dimensional hybrid metal halide device allows control of terahertz emissions
Researchers have utilized two-dimensional hybrid metal halides in a device that allows directional control of terahertz radiation generated by a spintronic scheme. The device has better signal efficiency than conventional terahertz generators, and is thinner, lighter and less expensive to produce. Terahertz (THz) refers to the part of the electromagnetic spectrum (i.e., frequencies between 100 […]
