“…Bacteria have been found in the most warmed underwater pools, where tectonic plates emanate pernicious gasses and incandescent material or in lakes of extreme saline composition, surrounded by an environment that is highly concentrated in arsenic, such as those found in Mono Lake, California [20]. To survive, bacteria can take organic and inorganic molecules from the surrounding environment and transform them into the substance required to start the cellular process in which oxidation-reduction mechanism is employed to obtain an energy source [21,22]. The overall redox process carried out by bacteria has been used in GO reduction by means of Shewanella [23], Bacillus subtilis [24], Extremophiles bacteria [25], Escherichia coli [26], and Gluconacetobacter xylinus [27].…”

Graphene-derived materials are currently studied because of their actual and projected applications. Among them, graphene oxide (GO) promises for outstanding applications as it can be prepared at large scale by simple, scalable, and low-cost techniques. The existent chemical methods based on the graphite exfoliation (phase solution and Hummers based) produce highly functionalized graphene, i.e., GO-like materials that converts into reduced GO (rGO) after a reduction treatment. The present work presents the current scenario on the GO green reduction methods, on the development of hierarchical carbon-based structures by the self-assembly of GO sheets at interfaces, and on rGObased hybrid nanocomposites. It is worth noting that, to date, the production and application of graphene-related materials are the fastest-growing research areas.

“…The reaction of these functional groups of GO is the principle of ecological preparation of graphene using a so-called green reduction of GO, thus reducing GO to graphene by using substances that are not harmful the environment. (Agharkar et al, 2014;Wang, Y. et al, 2011a) The reduction is usually carried out in order to restore electrical conductivity and at the same time there is a change of other properties of GO.…”

Abstract:This paper discusses the problematics of phytotoxicity of chemicals. It mainly focuses on the phytotoxicity of nanomaterials made of graphene. It describes phytotoxicological tests performed with foils from materials belonging to the graphene family. It also describes testing the infl uence of plants on these fi lms. Furthermore, the paper discusses the issues of mutual infl uence between plants and tested nanomaterials.

There is an increasing commercial demand for nanoparticles due to their wide applicability areas such as electronics, chemistry, catalysis, energy and medicine. Metallic nanoparticles are traditionally synthesized by wet -chemical techniques, where the chemicals used are quit toxic and inflammable. In the present report, bio-reduction of silver nitrate into silver nanoparticles using the plant of Moringa oleifera barks is reported. The synthesized silver nanoparticles are characterized by XRD, FTIR, UV-visible and antimicrobial activity analysis. From the XRD analysis it is found that the synthesized silver nanoparticles were the Face Centered Cubic structure and the crystalline size of the sample is 22.08 nm. FTIR data proved that the components in Moringa oleifera barks act as good reductants and stabilizers for the silver nanoparticles. The absorption in the visible region and broad peak at 480 nm was studied by UV studies. The antimicrobial activity of bio-synthesized silver nanoparticles was analyzed against E.coli and Staphylococcus bacteria. The results revealed that the bark extract is a very good bio reductant for the synthesis of silver nanoparticles.
