WebApr 14, 2024 · The laccase-catalyzed breakage of C–N, C–C, and C–O bonds can be used in preparing multifunctional polymeric materials, water pollution purification, and organic synthesis. Among these, laccase-catalyzed C–N bond breakage can be applied to remove the amino-protecting group in chemical synthesis. WebIf part of a crystal breaks due to stress and the broken piece retains a smooth plane or crystal shape, the mineral has cleavage. A mineral that never produces any crystallized fragments when broken off has no cleavage. Cleavage is often measured by three factors: 1) Quality of Cleavage.

First on the "hot drink" side - the thinner the crystal, the more you have to worry about breakage. There used to be crystal coffee mugs! Also, if there are a lot of "cuts" in the glass like on typical Waterford crystal, then that leads to thin areas next to thicker ones, which can also lead to breakage. Next, leaching.
WebSep 18, 2024 · In fluidized bed, crystal breakage produces a great quantity of fine debris. In general, the breakage mechanisms can be explained by indentation fracture of crystal surface. For indentation fracture, the crack … WebNov 15, 2024 · For crystal breakage there exists at least two major factors for investigation: the amount of breakage occurring (distributions), and form of the breakage mechanism (modes). Before dealing with the former, it is important to first describe what is meant when referring to different breakage types or “modes”.
WebMiner’s breakage decreases the value of a stone, particularly if it is on the crystal’s tip or termination. Obviously, a stone without breakage is more valuable than the one having some type of breakage. At times, if the damaged portion is removable, the stone’s value rises significantly.
