We recently worked on the Raman Spectroscopy of Graphene Oxide (GO). Graphite was the starting material of our work which was oxidized according to Hummer's method. The observed peaks in the Raman spectrum are D-band at 1353cm-1, G-band at 1592cm-1 and 2D band at 2703cm-1. Raman ...
Graphene oxide is highly desired for printing electronics, catalysis, energy storage, separation membranes, biomedicine, and composites. However, the present synthesis methods depend on the reactions of graphite with mixed strong oxidants, which suffer f
However, there has not been much exploration on the use of graphene/oxide interface for optoelectronic synapse which is important because it can get integrated easily with CMOS technology. In this work, we use a graphene/Ta2O5/graphene heterostructure to demonstrate optoelectronic synapses. Ta2O5 ...
This chapter is a review of the application of Raman spectroscopy in characterizing the properties of graphene, both exfoliated and synthesized, and graphene-based materials such as graphene-oxide. Graphene is a 2-dimensional honeycomb lattice of sp2-bonded carbon atoms and has received enormous inter...
Graphene oxide (GO) is a highly oxidized form of chemically modified graphene that consists of single atom thick layer of graphene sheets with carboxylic acid, epoxide and hydroxyl groups in the plane. From: Journal of Controlled Release, 2014 ...

Xu et al. carried out Auger electron spectroscopy (AES) element measurement on SiO2, as the result, O2escaped from SiO2after annealing in UHV or CVD (Figure 8c) [93]. Despite the small amount of O2released, the O2concentration between the narrow gap (15 μm) of Cu and oxide substrate...
Graphene oxide (GO) enhanced textiles were studied using Raman spectroscopy. Compared with regular textiles, GO-enhanced textiles show GO's signature D and G peaks at 1,350 and 1,580 cm(-1); they also show GO's harmonics peaks at 2,690 and 2,925 cm(-1). The intensity of GO's ...
Graphene oxide (GO) sheets have been used to construct various bulk forms of GO and graphene-based materials through solution-based processing techniques. Here, we report a highly cohesive dough state of GO with tens of weight percent loading in water wi
The optical response of a graphene oxide integrated silicon micro-ring resonator (GOMRR) to a range of vapour phase Volatile Organic Compounds (VOCs) is reported. The response of the GOMRR to all but one (hexane) of the VOCs tested is significantly higher than that of the uncoated (control...
