Study on Preparation of Nanocarbon Fibers from Wheat-Straw

In this study, we develop a convenient and green method to prepare biomass nanofibers using a simple method. At first wheat-straw was pretreated using concentrated sulfuric acid and hydrogen peroxide for the carbonization, and then the treated wheat straw and polyacrylonitrile(PAN) were dispersed in N,N-dimethylformamide(DMF) for spinning.

Capacitors | Water Analogy to Circuits | Douglas Wilhelm Harder

Explaining a capacitor in terms of this analogy with a flow of water is more difficult; however, we will look at associating the capacitor with an unstretched membrane blocking the flow of water as is shown in Figure 1. Figure 1. A pump in a closed loop with a membrane blocking the flow. Suppose we turn on the pump. We now have a force which begins to move the water and

8.2: Capacitors and Capacitance

A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum, and, in that case, a

What is Stray Capacitance?

This is because capacitance or a device that acts as an capacitor has high impedance to low-frequency signals. Thus, it is difficult for low-frequency signals to pass through a circuit that exhibits capacitive qualities. When you add unwanted capacitance into a circuit, the circuit can now act (again unwanted) to block low-frequency signals. Thus, an inductor, which is a device
