The world of science is always in a state of flux, evolving and growing with each new discovery. Recently, the race to create the blackest material has seen an exciting development. A newly created ...

Gamma radiation is the most penetrating and energetic form of nuclear radiation. To absorb half the incoming Gamma you need two and a half inches of concrete or almost half an inch of lead. So my ...

The United States Nuclear Regulatory Commission (USNRC) defines it as the process of radiation attenuation achieved by placing an absorbent substance between an individual, a workspace, or a radiation ...

A “metasheet” that is extremely efficient at absorbing electromagnetic radiation in a very narrow band of wavelengths, while remaining transparent elsewhere in the spectrum, has been produced by ...

Exploring “space weather” – or changes in the Earth’s space environment caused by the sun – means plunging into extremes of temperature, radiation and magnetic interference. When NASA’s twin Radiation ...

A recent discovery by materials science researchers in Drexel University’s College of Engineering might one day prevent electronic devices and components from going haywire when they’re too close to ...

A group of scientists from Florida State University has generated a new generation of organic-inorganic hybrid materials that can enhance image quality in CT scans, X-Ray machines, and other radiation ...
