Metal sleeves are used as carriers for the abrasive layer of sawing beads. In the SOFC stack, ammonia is cracked to hydrogen and nitrogen. This invention further provides improvements in mobility and transconductance over deep submicron state-of-the art Si pMOSFETs in addition to having a broad temperature operation regime from above room temperature down to cryogenic low temperatures where at low temperatures even high device performances are achievable. A third version of the invention uses a rotatable fixture to position the assembly beneath a UV laser light source to cure the compound.
