Mica is used in plastic automobiles fascia and fenders as a reinforcing material, providing improved mechanical properties and increased dimensional stability, stiffness, and strength. Mica-reinforced plastics also have high-heat dimensional stability, reduced warpage, and the best surface properties of any filled plastic composite.
MHC class I polypeptide–related sequence A (MICA) is a highly polymorphic cell surface glycoprotein encoded by the MICA gene located within MHC locus. [5] MICA is related to MHC class I and it has similar domain structure, however, it is not associated with β2-microglobulin nor binds peptides as conventional MHC class I molecules do. [ 6 ]
Muscovite (also known as common mica, isinglass, or potash mica [6]) is a hydrated phyllosilicate mineral of aluminium and potassium with formula KAl 2 (AlSi 3 O 10)(F,OH) 2, or 2 (Al 2 O 3) 3 (SiO 2) 6 (H 2 O). It has a highly perfect basal cleavage yielding remarkably thin laminae (sheets) which are often highly elastic.
In 2024, we are changing the proposal process. We are trying to reduce the number of failed attempts to start groups. While we re-structure the pages, please do not propose any new groups. In the meantime, please consider two thousand existing projects and/or try to revive one of the many dormant WikiProjects. If your group can't wait for the ...
Identify the subject: Link to several major articles or lists within the scope of the proposed project. Show the subject is big enough: Link to categories within the scope of the proposed project. (See How to link to a category.) Successful WikiProjects usually have thousands or tens of thousands of articles within their scope.
It is available in a ground-based version, VL MICA, fired from a truck-mounted box launcher, and a naval version, VL MICA-M, fired from a ship-fitted vertical launch system. [9] On October 23, 2008, 15:30, at CELM, Biscarosse ( Landes ), a VL MICA missile successfully performed the last of its 14 test firings meaning it is now ready for mass ...
When a freshly cleaved mica surface is placed in contact with water, hydrated potassium ions can desorb from the mica surface, leading to a negative charge at the surface. Similar to silicon, the surface of mica does not contain an appreciable density of silanol groups for covalent attachment by silanes. [ 11 ]
A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
