Summary
Titanium oxynitide (TiNO) nanowires exhibit superior performance as electrode materials for supercapacitors compared to thin films. This enhanced energy storage is due to their higher capacitance and energy density, making TiNO a promising material for charge-storage applications.
Area of Science:
- Materials Science
- Nanotechnology
- Electrochemistry
Background:
- Two-dimensional (2D) titanium oxynitide (TiNO) thin films and one-dimensional (1D) TiNO nanowires are synthesized.
- Pulsed laser deposition (PLD) is employed as a synthesis method.
- First-principles calculations are used to understand material properties.
Purpose of the Study:
- To synthesize high-quality TiNO thin films and nanowires.
- To investigate the structural and electrochemical properties of TiNO materials.
- To evaluate TiNO as a potential electrode material for supercapacitors.
Main Methods:
- Synthesis of TiNO thin films and nanowires via pulsed laser deposition.
- First-principles calculations to determine surface orientation and termination effects.
- Electrochemical characterization of specific capacitance and energy density.
Main Results:
- TiNO nanowires demonstrate a specific capacitance of 2725 mF/cm², significantly higher than TiNO thin films (400 mF/cm²).
- Nanowire samples exhibit a higher energy density (1.35 μWh/cm²) compared to thin films (0.33 μWh/cm²).
- First-principles calculations support the experimental observation of the (110) orientation in TiNO nanowires.
Conclusions:
- TiNO nanowires offer a six-fold increase in specific capacitance over TiNO thin films.
- The enhanced performance of nanowires is attributed to their high packing density.
- TiNO in both thin-film and nanowire forms shows promise for supercapacitor electrodes and charge-storage applications.

From the study of resistive circuits, it is understood that employing a series-parallel combination serves as an effective strategy for simplifying circuits. Capacitors can be arranged within a circuit in one of two ways: a series configuration or a parallel configuration. The way these capacitors are connected to a battery will influence both the potential drop across each individual capacitor and the size of the charge that each capacitor can store. This is determined by the specific type of...

Multiple capacitors can be connected in a circuit in series or parallel configuration. When the capacitor combination is connected to a battery, the potential drop across each capacitor and the magnitude of charge stored in the individual capacitor depends on the type of the connection. The capacitor combination is replaced by a single equivalent capacitor that stores the same amount of charge as the combination for a given potential difference.

A device consisting of two electrical conductors that are separated by a distance and used to store electrical charges is called a capacitor. The space between the conductors is either a vacuum or an insulating material, called a dielectric. Capacitors have many applications, ranging from filtering static from radio reception to energy storage in heart defibrillators.
When the conductors are two identical parallel plates, it is called a parallel plate capacitor. When battery terminals are...

1.6K
In integrated circuit technology, a capacitance multiplier is often utilized to produce a larger capacitance value when a small physical capacitance falls short. This is achieved by a circuit that multiplies capacitance values by a factor of up to 1000, such that a 10-pF capacitor can replicate the performance of a 100-nF capacitor.
The circuit illustrated in Figure 1 below incorporates two op-amps, with the first operating as a voltage follower and the second acting as an inverting amplifier.

In electrical power systems, understanding the capacitance of transmission lines is fundamental for efficient operation.
Single-Phase Lines
Consider a single-phase, two-wire transmission line with equal phase spacing energized by a voltage source. One conductor carries a uniform positive charge, while the other carries an equal negative charge. The capacitance C of the line can be derived from the voltage V between the conductors. For a one-meter section of the line, the capacitance is given...
