This paper, published in the Physical Review Letters, [9] repeated Shechtman's observation and used the same illustrations as the original paper. Originally, the new form of matter was dubbed "Shechtmanite". [30] The term "quasicrystal" was first used in print by Paul Steinhardt and Dov Levine [2] shortly after Shechtman's paper was published.
An aperiodic tiling is a non-periodic tiling with the additional property that it does not contain arbitrarily large periodic regions or patches. A set of tile-types (or prototiles) is aperiodic if copies of these tiles can form only non-periodic tilings. The Penrose tilings are a well-known example of aperiodic tilings. [1] [2]
Synthetic condensates are an important tool in synthetic biology, and have a wide and growing range of applications. Engineered synthetic condensates allow for probing cellular organization, and enable the creation of novel functionalized biological materials, which have the potential to serve as drug delivery platforms and therapeutic agents.

In plane geometry, the einstein problem asks about the existence of a single prototile that by itself forms an aperiodic set of prototiles; that is, a shape that can tessellate space but only in a nonperiodic way. Such a shape is called an einstein, a word play on ein Stein, German for "one stone". [2]
Biotic material, natural material, or natural product, a material produced by a living organism; Biomass, living or dead biological matter, often plants grown as fuel; Biomass (ecology), the total mass of living matter in a given environment, or of a given species; Body fluid, any liquid originating from inside the bodies of living people
Thairo Estrada and the Colorado Rockies finalized a one-year contract Thursday, a deal that includes a mutual option for 2026. Estrada has a .251 average with 48 homers, 195 RBIs and 52 stolen ...
A Penrose tiling with rhombi exhibiting fivefold symmetry. A Penrose tiling is an example of an aperiodic tiling.Here, a tiling is a covering of the plane by non-overlapping polygons or other shapes, and a tiling is aperiodic if it does not contain arbitrarily large periodic regions or patches.
The Giants let Saquon Barkley leave the team in free agency. He signed with the Eagles and became one of just nine RBs to eclipse 2,000 rushing yards.
