TL;DR: In this article, the effect of chemical and thermal reduction on the quality of chemically synthesized graphene and its derivatives was explored using Raman spectroscopy and X-ray diffraction, field emission scanning electron microscopy (FESEM) and atomic force microscopy.
Abstract: Large-scale fabrication of graphene and reduced graphene oxide (rGO) is important for industrial and research applications of this material. Chemical solution methods offer a low-cost alternate to produce rGO with high yield. This research is to explore the effect of chemical and thermal reduction on the quality of chemically synthesized graphene and its derivatives. A top-down process involved the chemical oxidation of the precursor graphite powder (size ~10 μm) using a concentrated mixture of sulphuric acid and nitric acid. Oxidized graphite powder was thermally exfoliated at 1,050°C for 30 s to produce graphene oxide (GO). Chemical reduction in GO sheets with sodium borohydride led to the formation of rGO. Characterization by Raman spectroscopy revealed an intensity ratio of 2D/G bands of rGO as approximately 0.5 indicating a multi-layered structure. X-ray diffraction, field emission scanning electron microscopy (FESEM) and atomic force microscopy (AFM) results indicated a multi-layered rGO wit...

TL;DR: In this article, the currentvoltage characteristics of Al/methyl-red/Ag surface-type structure were investigated in air at room temperature, using three different methods: conventional forward bias I-V method, Cheung functions and modified Norde's function.
Abstract: The current–voltage (I–V) characteristics of Al/methyl-red/Ag surface-type structure were investigated in air at room temperature. The conventional forward bias I–V method, Cheung functions and modified Norde's function were used to extract the diode parameters including ideality factor, barrier height and series resistance. The parameter values obtained from these three different methods were found in good agreement.

TL;DR: In this article, the authors proposed a model to measure the CO2 emission linkages among the productive sectors in Italy using data obtained in 2011, and the results obtained from these measures will enable them to formulate hypothesis about the direction and strength of the relationship between various linkages and also indicate which key CO2 emitter sector measures are most similar and which are most dissimilar.
