Microscale Techniques - Recrystallization - McMaster Chemistry
Nov 25, 1997 . Microscale Laboratory Techniques - Recrystallization . Most commonly, the material is transferred to the filter by pouring, using a microspatula to help transfer the crystals from the vial to the filter. . Fresh, cold solvent is added to wash the crystals, and this is then removed with the pipet in the same way.
Mesoscale manufacturing - Wikipedia
A less traditional technique is to use focused ion beam sputtering (FIB) to remove material. This process involves focusing a beam of ions, like from the gallium, to the work piece and this causes material to be removed. Using The FIB sputtering has a relatively low rate of material removal and therefore has limited application.

Armed conflict impacts on the microscale - IOPscience
showed that the material removal area extends sufficiently deep into the sub-surface to create a crater- like indentation. Further exacerbation of this damage is seen in figure 2[B]; compression of the subsurface at the point of impact in the sub-surface zone is resultant in a complex fracture network. The fracture network.
Investigations into Cutting Forces and Surface . - Science Direct
features oNuyama and TaNada (1998), Asad, et.al (2007). When machining is scaled down from macro to micro scale, there is change in the mechanism of material removal ( i.e ploughing, cutting ) and mostly it depends on the edge radius. When uncut chip thicNness is less than the edge radius there is non linear increase.
Scaling Effects on Materials Tribology: From Macro to Micro Scale
May 18, 2017 . A similar behavior of the friction was also observed at the micro-scale (i.e., using a ball-on-flat microtribometer) for the silicon sample. However, the friction of the .. As the pin continues to slide, the transfer material grows larger and is eventually removed causing positive wear. This ends up being a cyclic.
