Graphene is a well-known two-dimensional material with large surface area and used for numerous applications in variety of fields. Metal-free carbon materials such as graphene-based are widely an electrocatalyst oxygen reduction reactions (ORRs). Recently, more attention has been paid to developing metal-free graphenes doped heteroatoms N, S, P efficient electrocatalysts ORR. In contrast, we found our prepared graphene from oxide (GO) by the pyrolysis method under nitrogen atmosphere at 900...
Vanadium oxides, such as V 2 O 3 , VO and 5 have attracted considerable attention because of the fascinating physical properties each oxidation state. On other hand, precisely controlling individual states is difficult due to sensitivity oxygen stoichiometry. This article reports that reactive annealing (ROA) can systematically change state vanadium oxide films grown on a c‐Al substrate compared with typical under environments. Chemical, structural, electronic, electrical analysis confirms...
In this study, we developed an integrated optical coherence tomography - photoacoustic microscopy (OCT-PAM) system to simultaneously provide absorption and scattering information. Two different laser sources, such as a pulsed for PAM superluminescent diode OCT, were employed implement the OCT-PAM system. The performance of was measured by imaging carbon fibers. We then imaged black white hairs demonstrate simultaneous capabilities. As result, OCT can produce 3-D images both hairs, whereas is...
