A concrete densifier is a chemical applied to a concrete surface in order to fill pores, increasing surface density [clarification needed]. Chemical densifiers are used on polished and non-polished concrete to reduce dusting and wear; on polished concrete surfaces densifiers help concrete take a better polish and make the surface less permeable ...
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.
Diamond is the allotrope of carbon in which the carbon atoms are arranged in the specific type of cubic lattice called diamond cubic. It is a crystal that is transparent to opaque and which is generally isotropic (no or very weak birefringence ). Diamond is the hardest naturally occurring material known. Yet, due to important structural brittleness, bulk diamond's toughness is only fair to ...

In the administrative divisions of Qatar, zones ( Arabic: مَنَاطِق manāṭiq; singular مِنْطَقَة minṭaqa) are the second-highest level of government after municipalities. As of the 2015 census, there were 98 zones across the country. [1] However, several of these zones are not currently in use. [2] Over the years, numerous changes in zones have taken place. For instance, in ...
Synthetic diamond. Lab-grown diamonds of various colors grown by the high-pressure-and-temperature technique. Laboratory-grown ( LGD ), also called lab-grown diamond, [1] laboratory-created, man-made, artisan-created, artificial, synthetic, or cultured diamond, is diamond that is produced in a controlled technological process (in contrast to ...
