We have reported the electrochemical properties of the nanocomposites that were synthesized by immobilizing nanoparticles of Ag and Ni on the surface of reduced graphene oxide (RGO). The hierarchical structure derived from the combination of nanoparticles of Ni, Ag, and RGO in the (Ag x Ni(1–x)) y RGO(100–y) nanocomposite provides a synergistic effect in the enhancement of supercapacitive performance of the synthesized nanocomposite. (Ag0.50Ni0.50)90RGO10 showed a high specific capacitance value of 897 F g–1 at a current density 1 A g–1 and an energy density of 80 Wh kg–1 at 400 W kg–1 power density. This nanocomposite also exhibited ∼77% retention of the initial capacitance even after 4000 cycles. To the best of our knowledge, the electrochemical properties of the nanocomposite composed of Ni and Ag nanoparticles and RGO are reported for the first time, and the nanocomposite (Ag0.50Ni0.50)90RGO10 demonstrated its excellent supercapacitive performance.

“…Recently, carbon fillers [e.g., graphene oxide (GO), carbon nanotubes (CNTs), and graphene] have been applied to a wide variety of fields, owing to their extraordinary characteristics 13 – 16 . Graphene (a single atomic layer of graphite with an ideal 2D sp 2 -hybridized structure) and CNTs (cylindrical graphene tubes with a 1D sp 2 -hybridized structure) have been highlighted as reinforcements in polymer matrices because of their many advantages, such as outstanding thermal and mechanical properties, high specific surface areas, chemical stability, and superior electrical conductivity 17 – 19 . Due to these unique properties, graphene and CNTs are prospective candidates for various applications, such as electronics, sensors, and energy storage and conversion devices.…”

In this study, a homogeneous and stable dispersion of graphene oxide (GO)/carbon nanotube (CNT) complexes (GCCs) was obtained by dispersing CNTs in an aqueous solution using GO in the absence of dispersing agents. Furthermore, carboxymethyl cellulose/GCC (CMC/GCC) nanocomposite films were prepared by a simple solution mixing-evaporation method. The dispersibility of the GCCs with different CNT contents was investigated by UV-Vis spectrophotometry. The morphological and crystalline structures of the samples were analyzed by transmission electron microscopy, scanning electron microscopy, and X-ray diffraction. X-ray photoelectron spectroscopy and Fourier-transform infrared spectroscopy were conducted to identify the chemical composition of GO, CNTs, and GCCs. These results revealed that CNTs could be stably dispersed in water using GO. In addition, when CMC/GCC nanocomposite films were prepared by mixing CMC and GCCs, CNTs were uniformly dispersed in the CMC matrix. The tensile behavior was investigated using a universal testing machine. The tensile strength and Young’s modulus of the CMC/GCC nanocomposite films were significantly improved by up to about 121% and 122%, respectively, compared to those of pure CMC because of uniform and strong π-π interfacial interactions between CNTs and CMC polymer.

“…In recent years, due to their excellent characteristics, carbon nanostructures, including graphene, graphene oxide (GO), and carbon nanotubes (CNTs), have attracted enormous attention and been applied to a wide variety of fields [15][16][17][18]. These carbon nanostructures have been successfully used as a filler for the reinforcements in polymer matrices due to their outstanding thermal and mechanical properties, high specific surface areas, chemical stability, and superior electrical conductivity [19][20][21].

Salinity Stress Mitigation Using Encapsulated Biofertilizers for Sustainable Agriculture

The harmful effect of salinity stress on crops needs to be mitigated. Therefore, the application of microbial inoculum in combination with nanomaterials and methyl salicylate was investigated. Initially, different seeds were exposed to salinity levels treated with variable microbial treatments using different modes of applications. The microbial treatments included application of cyanobacterial strain Cyanothece sp. and the rhizobacterium Enterobacter cloacae, alone or in combination with one another, and a final treatment using combined microbial inoculum supplied with methyl salicylate. Later, different nanomaterials were used, namely, graphene, graphene oxide, and carbon nanotubes in combination with biofertilizers on the highest salinity level. The nanomaterial with microbial treatment and methyl salicylate were applied partly as a mixture in soil and partly as capsules. Results showed that salinity stress had a drastic inhibitory effect on growth parameters, especially at −5 MPa level. Nonetheless, the microbial treatments significantly alleviated the deleterious effect of salinity stress, especially when combined with methyl salicylate. When the nanomaterials were added to biofertilizers at highest salinity level, the inhibitory effect of salinity was mostly alleviated. Smart use of synergistic biofertilizers alongside the right nanomaterial, both encapsulated and in soil, would allow for mitigation and alleviation of inhibitory effect of salinity.
