| complexing agent |
Chelation (from Greek χηλή, chelè, meaning claw) is the process of reversible binding of a ligand, the chelator or chelating agent, to a metal ion, forming a metal complex, the chelate. The ligand does not have to be organic. In contrast to the simple monodentate ligands like H2O or NH3, which are easily broken apart by other chemical processes, the polydentate chelators form multiple bonds with the metal ion, resulting in more stable complexes. ...

| compound eye |
A compound eye is a visual organ found in certain arthropods such as some insects and crustaceans. It consists of between 12 and 1,000 ommatidia which are tiny sensors that distinguish between brightness and darkness. The image perceived by the arthropod is a combination of inputs from the numerous ommatidia, which are oriented to point in slightly different directions. ...

| compression molding |
Compression molding is a method of molding in which the molding material, generally preheated, is first placed in an open, heated mold cavity. The mold is closed with a top force or plug member, pressure is applied to force the material into contact with all mold areas, and heat and pressure are maintained until the molding material has cured. The process employs thermosetting resins in a partially cured stage, either in the form of granules, putty-like masses, or preforms. ...

| compound |
In military science, a compound is a type of fortification made up of walls surrounding several buildings in the center of a large piece of land. The walls can either serve the purpose of being tall, thick, and inpenetrable, in which case they would be made of wood, stone, or some other like substance; or dangerous to attempt to scale, in which case they could be made of barbed wire or electrified. ...
