Thermo optic coefficient silica
Webbför 8 timmar sedan · As depicted in the graph, NMs showed a significant increase in the diffusion coefficient dependent on urea concentration, reaching a maximum of 1.3 ± 0.3 μm 2 /s at 300 mM of urea (increase of 62%). Next, we examined the collective motion dynamics and swarming behavior of the IONP motors in vitro by optical microscopy. WebbIn this work, the thermo-optic coefficient (TOC) of the silicon-rich amorphous silicon carbide (a-SiC) thin film deposited by plasma-enhanced chemical vapor deposition (PECVD) was characterized. We found that the TOC of the film increases as its silicon content increases. A more than threefold improvement in the TOC was measured, …
