“…Deletion of strain on the C-C bond in the epoxy groups forms the wrinkles [48]. The obtained result is in good agreement with many recent studies depicting graphene sheets obtained from GO, by various techniques, possessing to have curled morphologies consisting of thin, wrinkled, paper-like structures, with fewer layers and having larger specific surface areas than GO [49]. The FESEM micrograph of Ag-NPs reveals the formation of spherical particles within nano-range as depicted in figure 5b.…”

Many wounds are unresponsive to current available treatment techniques and therefore there is an immense need to explore suitable materials including biomaterials, which are being considered as the crucial factor to accelerate the healing cascade. In this study, we fabricated polyhydroxyalkanoate based antibacterial mats via electrospun technique. One-pot green synthesized graphene decorated silver nanoparticles (GAg) were incorporated into the fibres of poly-3 hydroxybutarate-co-12 mol% hydroxyhexanoate (P3HB-co-12mol% HHx), a co-polymer of polyhydroxyalkanoate (PHA) family which is highly biocompatible, biodegradable and flexible in nature. The synthesised PHA/GAg biomaterial was characterized by field emission scanning electron microscopy (FESEM), elemental mapping, thermogravimetric analysis (TGA), UV-visible spectroscopy (UV-vis) and Fourier transform infrared spectroscopy (FTIR). In-vitro antibacterial analysis were performed to investigate the efficacy of PHA/GAg against gram positive Staphylococcus aureus (S.aureus) strain 12600 ATCC and gram negative Escherichia coli (E.coli) strain 8739 ATCC. The results indicated that the PHA/GAg demonstrated significant reduction of Staphylococcus aureus (S.aureus strain 12600 ATCC) and Escherichia coli (E.coli strain 8739 ATCC) as compared to bare PHA or PHA-rGO in 2 hours of time. The P value (P< 0.05) was obtained by using 2 sample T-test distribution.

“…In 2010, the further progression of graphene-based host structures (i.e., hollow GO spheres, [ 43 ] RGO, [ 37,39,[44][45][46][47][48][49][50] unzipped CNT, [ 51 ] bottom-up-synthesized graphene, [ 52 ] CVD-synthesized graphene [ 40 ] and N-doped graphene [ 40 ] ) only enabled limited progresses (Table 1 ). However, some major advances in understanding the Li-ion storage mechanism in different kinds of graphene were reported.…”

that its extraordinary properties would enable revolutionary new technologies, which gave birth to the "graphene era". [ 3,4 ] Relying on this scenario, in 2013, the European Union launched the ¤1 billion "Graphene Flagship" project aimed to investigate the properties of this new form of carbon for various applications (e.g., electronics, sensors and energy storage devices), with the ambitious goal of guiding graphene from laboratories to commercial applications within a decade. [ 5,6 ] In the same period, the Chinese Government set up a similar investment to mass-produce graphene as thin fi lms (e.g., for touchscreen electrodes) and platelets (e.g., for use in batteries). [ 6 ] In the following years, hundreds of patents, mainly focused on manufacturing and application in energy storage, were fi led and the worldwide production of graphene and graphene-containing materials rapidly increased. Although a few Chinese industries claimed to already use graphene-containing materials for smartphone production, no revolutionary practical application relying on graphene has been yet developed. [ 6 ] Specifi cally with respect to the battery fi eld, a close analysis of the scientifi c literature reveals a struggle to meet the ambitious initial targets. A potential loss of focus from the fi nal application caused by hype and ease of publication on such a novel matter, together with the delivery of very misleading information [ 7,8 ] and erroneous statements [ 7 ] concerning the use of graphene in batteries are emerging as possible reasons of the ineffective graphene-era outburst. In this progress report, we do not focus on production and classifi cation of graphene and graphene-containing materials, which were already well reported in the past years. [ 3,[9][10][11] In contrast, due to the lack of an exhaustive analysis of the progression of the use of such materials in lithium-ion battery (LIB) anodes, we report here a critical evaluation of the most prominent research papers published from 2008 until the end of 2015. As shown in Figure 1 , three different stages of the graphene research in LIB anodes can be distinguished: a fi rst stationary phase between 2008 and 2010 where the lithium-ion storage properties of different graphene and graphene-containing materials were preliminarily explored, a second exponential stage, spanning from 2010 to 2014, where graphene and graphene-containing anode materials were broadly developed and investigated, and fi nally, a third phase, (i.e., starting from 2015), where the research seems to have approached a plateau. After Used as a bare active material or component in hybrids, graphene has been the subject of numerous studies in recent years. Indeed, from the fi rst report that appeared in late July 2008, almost 1600 papers were published as of the end 2015 that investigated the properties of graphene as an anode material for lithium-ion batteries. Although an impressive amount of data has been collected, a real advance in the fi eld still seems to be missing. In this framework, atten...

“…First, the pristine graphene sheets were prepared by rapid thermal expansion method according to our previous report [10]. Then, the pristine graphene sheets and melamine (Tianjin Kermel Chemical Reagent Co., Ltd., China) were mixed together with a weight ratio of 1:6 by grinding for 2 h. The mixture in a combustion boat was then placed in the center of a quartz tube in argon gas atmosphere and heated to 700 • C at a heating rate of 5 • C/min.…”

“…Graphene has been considered to be a promising anode material for lithium-ion batteries and exhibits a large reversible specific capacity due to its large surface area, superior electronic conductivity and high chemical stability [4][5][6][7][8][9][10]. In addition, the electronic and chemical properties of graphene can be modified by chemical doping heteroatoms, such as boron atoms and nitrogen atoms [11][12][13][14][15].…”
