Aug 6, 2024 · Ultraviolet radiation lies between wavelengths of about 400 nanometres (1 nanometre [nm] is 10 −9 metre) on the visible-light side and about 10 nm on the X-ray side, though some authorities extend the short-wavelength limit to 4 nm. In physics, ultraviolet radiation is traditionally divided into four regions: near (400–300 nm ...

It was when environmental reporter Robert Sollen said of the massive 1969 Santa Barbara oil spill, “the waves, so heavy and lubricated with oil, had lost their rhythmic crash.”
Aug 16, 2024 · Hyperuniform materials, characterized by their suppressed density fluctuations and vanishing structure factors as the wave number approaches zero, represent a unique state of matter that straddles the boundary between order and randomness. These materials exhibit exceptional optical, mechanical, and acoustic properties, making them of great interest in materials science and engineering.
