To prevent possible rust stains from affecting the exterior patina of the statue, the pretext was adopted of using aluminum. Screw jacks were used to brace the aluminum against the ...
Diamond-like carbon ( DLC) is a class of amorphous carbon material that displays some of the typical properties of diamond. DLC is usually applied as coatings to other materials that could benefit from such properties. [1] DLC exists in seven different forms. [2] All seven contain significant amounts of sp 3 hybridized carbon atoms.

Acridine orange is an organic compound that serves as a nucleic acid -selective fluorescent dye with cationic properties useful for cell cycle determination. Acridine orange is cell-permeable, which allows the dye to interact with DNA by intercalation, or RNA via electrostatic attractions. When bound to DNA, acridine orange is very similar ...
