“…The newly formed sp 2 carbon atoms in rGO are smaller in size compared to the sp 2 carbon atoms in Graphite before reduction. 40 The decrease in FWHM of the G band of rGO as compared to GO indicates an increased number of sp 2 carbon atoms. The average crystallite size of sp 2 domains is decreased in rGO compared to GO.…”

Wavelength dispersion of optical power limiting is an important factor to be considered while designing potential optical limiters for laser safety applications. We report the observation of broadband, ultrafast optical limiting in reduced graphene oxide (rGO), measured by a single open aperture Z-scan using a white light continuum (WLC) source. WLC Z-scan is fast when the nonlinearity is to be measured over broad wavelength ranges, and it obviates the need for an ultrafast tunable laser making it cost-economic compared to conventional Z-scan. The nonlinearity arises from nondegenerate two-photon absorption, owing mostly to the crystallinity and extended π conjugation of rGO.

“…The thickness of graphene coating in this study is around 1.675-2.01 nm (considering that there were 5-6 layers and the thickness of a single layer of graphene is 0.335 nm). The D-peak at 1350 cm −1 signifies the extent of defects in graphene [28]. The relatively high intensity of the D peak in Figure 1 indicates that the graphene layers had considerable defects (such as vacancies and strained hexagonal/non-hexagonal (pentagon or heptagon) distortions that are reported to result in corrugation and twisting of layers [28]).…”

Long-Term Corrosion Protection of a Cupro-Nickel Alloy Due to Graphene Coating

This study demonstrates the corrosion resistance of a Cu-Ni alloy coated with a multi-layer graphene. This is one of the first demonstrations of long-term corrosion resistance due to graphene coating, which is crucial since earlier studies have suggested graphene-coated copper to be considerably inferior to bare copper in terms of corrosion during long-term exposure to a corrosive environment. The inferior corrosion resistance of graphene-coated copper arises due to defects and poor surface coverage by graphene. Since it is prohibitively difficult to develop defect-free graphene on metals at a commercially feasible scale, this study investigated the hypothesis for an alternative approach, i.e., to develop multi-layer graphene with a reasonable assumption that the areas of defects/poor coverage of a layer will be masked by the subsequent over-layer(s). This study has validated this hypothesis. Electrochemical investigations have demonstrated multi-layer graphene to improve the corrosion resistance of a Cu-Ni alloy by an order of magnitude. However, the most striking finding of this study is that the improvement in corrosion resistance due to the multi-layer graphene coating sustained the entire duration of a long-term test (~350 h).

This review covers topics related to the synthesis of nanoparticles, the anodic and cathodic electrochemical reactions and low temperature electrochemical energy devices. The thermodynamic aspects of nucleation and growth of nanoparticles are discussed. Different methods of chemical synthesis such as w/o microemulsion, B ö nnemann, polyol and carbonyl are presented. How the electrochemical reactions take place on the surface of the catalytic nanoparticles and the importance of the substrate is put in evidence. The use of nanomaterials in low temperature energy devices such as H 2 /O 2 polymer electrolyte or proton exchange membrane fuel cell (PEMFC) and micro-direct methanol fuel cell ( μ DMFC), as well as recent progress and durability, is discussed. Special attention is given to the novel laminar fl ow fuel cell (LFFC). This review starts with the genesis of catalytic nanoparticles, continues with the surface electrochemical reactions that occur on them, and fi nally it discusses their application in electrochemical energy devices such as low temperature fuel cells or Li-air batteries.
