Graphitic flux
WebJan 21, 2014 · Graphitic carbon nitride ... Φ1 is the quantum yield for H2O2 degrdn., and d[hν]abs/dt is the photon flux. The steady-state concn. of H2O2 is independent of the absorbed photon flux as predicted by the above equation; [H2O2]ss = Ψ0/Ψ1. Steady-state concns. of H2O2 of >100μM were obtained in illuminated suspensions of ZnO. In the … WebThe graphitic foam coupled to a swirl tube serves as a high-thermal-conductivity heat sink that cannot melt, although it can sublime at much higher temperatures than copper melts. Together, they comprise a robust plasma-facing component (PFC) weighing roughly 5% of an all-W component or 17% of a traditional W-coated copper heat sink ...
