Liquid crystals express the properties of both liquids and solids. They are loosely bound and flow like liquids but their atoms or molecules are arranged in a crystalline matrix.Answer and Explanation: Liquid crystals are made from a wide variety of organic and inorganic compounds that create rod-...
On Mars, large quantities of water are frozen in the polar ice caps and under the planets surface. How could these resources be incorporated into a self-sustaining ecosystem? Allow the ice to melt at room temperature. What is the state of molecules in the liquid water now? How did the en...
Hydroxyapatite moleculescan group together (crystallize) to form microscopic clumps, called hydroxyapatite crystals. Tiny crystals of hydroxyapatite sometimes form in or around joints and can cause inflammation of joints and tissues around the joints, such as tendons and ligaments. ...
This is indeed found when surface antigens are either embedded in a fluid lipid membrane or are part of a flexible matrix and thus possess high lateral mobility facilitating stress-free bivalent binding of IgG molecules. How- ever, naked viruses and a great number of prokaryotes, including ...
it is composed of two independent interpenetrating networks of H-bonded water molecules (shown above in blue and red, respectively) the main structural motif is a tricyclic, cage-like water hexamer, similar as in liquid water A tricyclic water hexamer composed of four-membered rings This motif...
linked by α-1,4-glycosidic bonds. Subsequently, these short-chain oligosaccharides covalently bound to glycogenin molecules are further extended via α-1,4-glycosidic linkages and spread out via α-1,6-glycosidic bonds at branch points by other enzymes of the glycogen biosynthesis pathway [2,3]...
Polycrystalline solar cells are also silicon cells, but rather than being formed in a large block and cut into wafers, they are produced by melting multiple silicon crystals together. Many silicon molecules are melted and then re-fused together into the panel itself. Polycrystalline cells are less...

(Binder et al., 2005). Chronic stroke infarcts almost certainly contain foamy macrophages undergoing apoptosis, because at 4 weeks and 8 weeks following stroke these cells are laden with cholesterol crystals, which are potent inducers ofprogrammed cell deathviainflammasomesignaling (Chung et al., ...
What state of matter is an ice cube? What kind of chemical bond produces crystalline lattices? Are covalent compounds crystalline solids? Are all metals crystalline solids? Are liquid crystals solids? How do molecules in a solid differ from those in a liquid or gas?
