Oxygen Vacancies Enhancing Capacitive Properties of MnO2 Nanorods for Wearable Asymmetric Supercapacitors

1 answer:

6 0

By creating oxygen vacancies, we show how to increase the conductivity and capacitive performance of MnO2 intrinsically. The electrochemical performance of oxygen-deficient MnO2 nanorods (NRs) generated by a simple hydrogenation treatment is much better than that of the untreated MnO2 electrode.

<h3>what is an Asymmetric Supercapacitors?</h3>

The insufficient capability of energy-storage devices frequently stymies ongoing technical developments in different domains such as portable gadgets, transportation, and green energy. Asymmetric supercapacitors can extend their working voltage window beyond the thermodynamic breakdown voltage of electrolytes while solving the energy storage restrictions of symmetric supercapacitors by utilising two distinct electrode materials. This review provides in-depth expertise in this topic. To comprehend the wide-ranging research in this area, we first look at the basic energy-storage mechanisms and performance evaluation criteria for asymmetric supercapacitors.

Give the number of sigma bonds and pi bonds for benzene, c6h6.

beks73 [17]

Answer:

There are 12 sigma bonds and 3 pi bonds in benzene

Explanation:

Molecular formula of benzene is $C_{6}H_{6}$ .

Here six carbon atoms are joined together through alternative single and double bond forming a six membered cyclic ring.

Six hydrogen atoms are attached to six carbon atoms through a single bond.

A single bond represents a sigma bond. A double bond consists of a sigma bond and a pi bond.
In the Lewis structure of benzene, there are three C-C single bonds, three C=C double bonds and six C-H single bond.
Hence there are 12 sigma bonds and 3 pi bonds in benzene
Lewis structure of benzene is given below

oils will dissolve best in solvents that are? A. polar B. nonpolar C. either polar or nonpolar D. neither polar nor nonpolar

Genrish500 [490]

The answer is <span>B. nonpolar.

Polar molecules dissolve best in polar solvents while nonpolar molecules dissolve best in nonpolar solvents. </span>Oils are nonpolar. So, they will dissolve best in nonpolar solvents. If you put oil in some polar solvent, such as water, it will hardly dissolve.
