Nuclear detonations unleash an astonishing amount of destructive force. But the extreme pressure and temperature that they generate also makes nuclear blasts a cauldron of chemical creation, capable of delivering new and surprising scientific discoveries. In the 1950s, for instance, scientists examining debris from US hydrogen bomb tests found two new elements, which now occupy numbers 99 and 100 in the periodic table. They named them after prominent nuclear scientists: einsteinium for Albert E...

By Kit Chapman2021-05-17T19:02:00+01:00 Scientists have found what might be the oldest synthetic quasicrystal in the debris of the first-ever atomic bomb test almost 76 years ago. The report brings together two of the strangest phenomena in chemistry. On 16 July 1945, the Trinity test became the first nuclear detonation, carried out in the New Mexico desert as part of the Manhattan Project during the second world war. In the resulting explosion, particles of silicate-based desert sand were suck...

Credit: Courtesy of Fernando Guevara Vasquez Mathematicians and engineers at the University of Utah have teamed up to show how ultrasound waves can organize carbon particles in water into a sort of pattern that never repeats. The results, they say, could result in materials called "quasicrystals" with custom magnetic or electrical properties. The research is published in "Quasicrystals are interesting to study because they have properties that crystals do not have," says Fernando Guevara Vasq...
