Here, we have fabricated the spinel binary-metal oxide (FeCo2O4) via a solvent-free and cost-effective approach. The nanocomposites of the as-fabricated binary-metal spinel oxide have been prepared with three different conductive-matrices, namely r-GO, CNTs, and PANI, via ultra-sonication approach. The spinel phase and surface functionalities of the fabricated FeCo2O4 sample have been confirmed via XRD and FT-IR analyses, respectively. The morphological-structure and elemental composition of the fabricated samples have been probed via FESEM and EDX results. The role of added conductive-matrices in the improvement of the electrical conductivities of the fabricated nanocomposites has been investigated via I–V experiments. The electrochemical experiments, conducted in half-cell configuration, showed that FeCo2O4/PANI nanocomposite exhibited the highest specific capacitance (658.9 Fg-1) than that of the remaining two nanocomposites. Furthermore, FeCo2O4/PANI nanocomposite exhibited excellent cyclic stability as it lost just 8.3% of its initial specific capacitance even after 3000 cyclic tests. The superior capacitive-activity of the FeCo2O4/PANI nanocomposite is accredited to its high conductivity, large surface area, and synergy effects between the pseudocapacitance derived from the PANI and FeCo2O4 nanostructure. The electrochemical and electrical measurements suggested that FeCo2O4/PANI nanostructure is an emerging contender for energy storage applications. 相似文献

Vanadium nitride(VN) was deposited by DC-sputtering on a vertically aligned carbon nanotube(CNTs)template for the purpose of nano-structuration. This led to the fabrication of hierarchically composite electrodes consisting of porous and nanostructured VN grown on vertically aligned CNTs in a nano-treelike configuration for micro-supercapacitor application. The electrodes show excellent performance with an areal capacitance as high as 37.5 m F cm~(-2) at a scan rate of 2 mV s~(-1) in a 0.5 MK_2SO_4 mild electrolyte solution. Furthermore, the capacitance decay was only 15% after 20,000 consecutive cycles. Moreover,the capacitance was found to increase with VN deposit thickness. The X-ray photoelectron spectroscopy analyses of the electrodes before and after cycling suggest that the oxide layers that form at the VN surface is the responsible for the redox energy storage in this material. Such electrodes can compete with other transition metal nitride based electrodes for micro-supercapacitors. 相似文献

The present research reports of quick and marked changes induced by plant extract of Euryops arabicus in the
gene expression of 49-kDa apyrases, cytoskeletal proteins, ATPases, ADPase and amount of amino acid of pea (Pisum
sativum L. var. Alaska). Pellets of cytoskeletals proteins (27000 xg) were probed with anti-apyrase antibody, biotinylated
anti-rat, actin and alpha and beta-tubulin for Western blotting. ATPase and ADPase activities were determined based
on the hydrolytic efficacy of adenine triphosphate and adenine diphosphate. By 72 hours, the abundance of apyrases,
cytoskeletal proteins and amount of amino acid in pellets of 27000 xg of germinated pea seeds in E. arabicus extracts
were sharply increased than those sown in distilled water. All the samples exhibited that the stems had more amount
from apyrases, cytoskeletal proteins, amino acids and ATPase and ADPase activities than primary leaves and primary
roots that were germinated either on E. arabicus water extract or in distilled water. Based on the enzyme’s capability to
hydrolyse nucleotide triphosphate and nucleotide diphosphate as well as the direct association between expression of
49-kDa apyrase and cytoskeletal proteins, E. arabicus water extract had an important effect on plant germinations. 相似文献
