(Phys.org)—A small team of researchers from the U.S. and Italy has found evidence of a naturally formed quasicrystal in a sample obtained from the Khatyrka meteorite. In their paper published in the journal Scientific Reports, ...
Crystals are defined by their repeating, symmetrical patterns and long-range order. Unlike amorphous materials, in which atoms are randomly packed together, the atoms in a crystal are arranged in a predictable way. Quasicrystals ...
Charged particles can form via self-organization processes an unexpectedly large range of crystal structures entirely by themselves. A research team with participants from TU Wien has demonstrated how easily the formation ...
Remember the graph paper you used at school, the kind that's covered with tiny squares? It's the perfect illustration of what mathematicians call a "periodic tiling of space", with shapes covering an entire area with no overlap ...
Unlike classical crystals, quasicrystals do not comprise periodic units, even though they do have a superordinate structure. The formation of the fascinating mosaics that they produce is barely understood. In the context ...
Naturally formed quasicrystals—crystal-like solids with supposedly impossible symmetries—are among the rarest structures on Earth. Only two have ever been found.
(Phys.org)—A team of researchers with affiliations to the University of Tokyo and Tohoku University, both in Japan, have succeeded in filming the growth of a sample quasicrystal for the first time. In their paper published ...
DNA, the molecular foundation of life, has new tricks up its sleeve. The four bases from which it is composed snap together like jigsaw pieces and can be artificially manipulated to construct endlessly varied forms in two ...
Once a contradiction in terms, aperiodic crystals show instead that "long-range order" has never been defined. Whatever it means, decades of intense research have shown it to be more complex and surprising than anyone suspected ...
Late last spring, a doctoral student worked late into the night. As she doodled, her chemistry thesis took on a life of its own, transforming into a comic book.
