#Innovative Fabrication Technique for Hybrid Nanostructure Supercapacitor Electrode Offsetting this promise is the fact that,
while supercapacitors have the potential to charge faster and last longer than conventional batteries, they also need to be much larger in size
Thus, many scientists are working to develop green, lightweight, low-cost supercapacitors with high performance. Now two researchers from the S n. Bose National Centre for Basic Sciences, India, have developed a novel supercapacitor electrode based on a hybrid nanostructure made from a hybrid nickel oxide-iron oxide
exterior shell and a conductive iron-nickel core. In a paper published this week in the Journal of Applied Physics
from AIP Publishing, the researchers report the fabrication technique of the hybrid nanostructure electrode. They also demonstrate its superior performance compared to existing, non-hybrid supercapacitor electrodes.
Since nickel oxide and iron oxide are environmental friendly and cheap materials that are widely available in nature,
the novel electrode promises green and low-cost supercapacitors in future.""This hybrid electrode shows the superior electrochemical performance in terms of high capacitance the ability to store electrical charge of nearly 1415 farad per gram, high current density of 2. 5 ampere per gram,
low resistance and high power density,"said Ashutosh K. Singh, the primary researcher at the Department of Condensed Matter Physics and Material Sciences at the S n. Bose National Centre
the electrode could retain nearly 95 percent of initial capacitance after cycling or charging and discharging 3, 000 times."
"The Promise of Supercapacitorssupercapacitors are used electronic devices to store an extremely large amount of electrical charges.
They are also known as electrochemical capacitors, and they promise high power density, high rate capability, superb cycle stability and high energy density.
Conventional capacitors have high power density but low energy density, which means they can quickly charge
Supercapacitors are a bridge between conventional capacitors and batteries, combining the advantageous properties of high power, high energy density and low internal resistance,
reliable and potentially safer power source for electric and portable electronic devices in future, said Singh.
In supercapacitors, high capacitance, or the ability to store an electrical charge, is critical to achieve higher energy density.
National Centre for Basic Sciences, mixed nickel oxide and iron oxide as a hybrid material and fabricated the novel core/shell nanostructure electrode."
"By changing the materials and morphologies of the electrode, one can manipulate the performance and quality of the supercapacitors,
"Singh said. In Singh's experiment, the core/shell hybrid nanostructure was fabricated through a two-step method.
He explained that supercapacitors store charges through a chemical process known as a redox reaction, which involves a material giving up electrons
and transporting ions through another material at the interface between electrode and electrolyte. Larger redox reaction surfaces are essential for achieving a higher power density for supercapacitors."
"Moreover, the conductive Fe-Ni core provides a highway to accelerate the transport of electrons to the current collector,
and electrochemical properties of the electrode, realizing high-performance supercapacitors,"Singh noted. How the New Electrode Performedusing techniques called cyclic voltammetry and galvanostatic charge/discharge methods,
Singh and Mandal studied the electrochemical properties of the hybrid material electrode. Comparing with the counterpart,
non-hybrid electrodes like nickel/nickel oxide and iron/iron oxide core/shell nanostructure electrodes, the hybrid material electrode demonstrated higher capacitance,
higher energy density and higher charging/discharging time.""For example, the current density of the hybrid electrode is three and 24 times higher than that of nickel/nickel oxide and iron/iron oxide electrodes, respectively,
"Singh said.""The comparative results show remarkable enrichment in the electrochemical activities of nickel/nickel oxide
and iron/iron oxide electrodes after combining them together, which suggests the hybrid electrode's better supercapacitive properties."
"One feature of Singh's fabrication technique is that it doesn't require extra binder materials.
According to Singh, binding materials are used commonly in the fabrication of carbon or graphene based supercapacitors for attaching redox active material on the current collector.
Without the mass of binding materials, the hybrid electrode is a good candidate to make lightweight supercapacitors."
"The remarkable electrochemical performances and material properties suggest that the iron oxide-nickel oxide hybrid core/shell nanostructure could be a reliable and promising candidate for fabricating the next generation lightweight, low-cost
and green supercapacitor electrodes for real life application, "Singh said. The researchers'next plan is to develop a whole supercapacitor device based on the hybrid electrode and test its functional performance,
a step closer to manufacturing production. Source: http://www. aip. org g

antenna-rectifier diodes that convert light into DC current, have been built using multiwall carbon nanotubes with integrated nanoscale rectifiers.
The carbon nanotubes in the devices function as antennas for capturing light. When the light waves strike the nanotube antennas,
an oscillating charge is created that travels through the rectifier devices. A small direct current (DC) is created
a device that combines the functions of an antenna and a rectifier diode to convert light directly into DC current.
The antennas had to be sufficiently small enough for coupling optical wavelengths and the rectifier diode had to have the ability to operate rapidly to capture electromagnetic wave oscillations.
However, the low cost and potential high efficiency of a rectenna capable of capturing visible light caused researchers to continue their study.
which is sufficient for ejecting electrons out of the carbon nanotube antennas upon the absorption of visible light Light in the form of oscillating waves interacts with nanotubes after going through the calcium-aluminum electrode.
This means the electrons flow in one direction towards the top electrode. The 10nm diode functions at such a high frequency due to the ultra-low capacitance,
which is in a few attofarads. rectenna is basically an antenna coupled to a diode, but when you move into the optical spectrum,
that usually means a nanoscale antenna coupled to a metal-insulator-metal diode. The closer you can get the antenna to the diode
the more efficient it is. So the ideal structure uses the antenna as one of the metals in the diode
which is the structure we made-Prof Baratunde Cola, Georgia Tech The rectennas were grown on rigid substrates
however the team aims to grow rectennas on foil or other suitable materials for developing flexible photodetectors and solar cells.
