Potential energy surface for silver depositing on an aluminium–palladium–manganese (Al–Pd–Mn) quasicrystal surface. Similar to Fig. 6 in Ref. [1] A quasiperiodic crystal, or quasicrystal, is a structure that is ordered but not periodic.
MCM-41 (Mobil Composition of Matter No. 41) is a mesoporous material with a hierarchical structure from a family of silicate and alumosilicate solids that were first developed by researchers at Mobil Oil Corporation [2] and that can be used as catalysts or catalyst supports.

Since then, understanding of zinc in human biology has advanced to the point that it is considered as important as iron. Modern advancements in analytical technology have made it clear the importance of biometals in signalling pathways and the initial thoughts on the chemical basis of life. [2]
Bioinorganic chemistry is a field that examines the role of metals in biology.Bioinorganic chemistry includes the study of both natural phenomena such as the behavior of metalloproteins as well as artificially introduced metals, including those that are non-essential, in medicine and toxicology.
Joey Lawrence is owning up to his "mistakes" after reconciling with his wife Samantha Cope.. The actor, 48, announced his reconciliation with Cope, 37, on Dec. 4 via Instagram, and is now opening ...
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]
This lemon-dill tuna salad packs plenty of protein and gets a boost of flavor from sumac—a spice used in Middle Eastern, Mediterranean and North African cooking that adds a citrusy touch ...
