A new material developed at Penn State defies a fundamental law of physics, opening doors to highly efficient solar cells.

Seventy years ago, on September 17, 1955, a modified Convair B-36 departed Carswell Air Force Base in Texas. Legendary U.S.

In large doses, radiation can cause serious tissue damage and increase a person’s risk of later developing cancer. The low doses of radiation used for imaging tests might increase a person’s cancer ...

The study was conducted to address concerns among people who grew up downwind of Hanford that radiation releases may have caused autoimmune or heart disease. Because of the earlier Hanford Thyroid ...

The proposed method is based on the extraction of the transfer function between the component-level and the system-level radiated emissions. To demonstrate the practical correlation between the ...

A brief survey of the main features of solar emissions in connection with solar flares is given: ultraviolet and X-ray radiation, corpuscular emission, radio frequency radiation, and relativistic ...

The advent of lead halide perovskite nanocrystals (NCs), which are easily synthesized, ultralow-cost materials and have an impeccable luminous efficiency, has drastically changed the future ...

With the United States joining Israel in its attacks on Iran's nuclear program, here is what we know about the radiation threat, and other health risks. The U.N.’s nuclear watchdog, the ...

Already, Israel’s campaign has targeted Iran’s enrichment site at Natanz, centrifuge workshops around Tehran and a nuclear site in Isfahan. Its strikes have also killed top generals and nuclear ...

And because the paper converted the measured energy to emissions based on a global CO2 average, it only offered an estimate; it did not indicate the actual emissions generated by using these ...
