Atmosphere‐free activation methodology for holey graphene/cellulose nanofiber‐based film electrode with highly efficient capacitance performance

Rough Electrode Creates Excess Capacitance in Thin-Film Capacitors

The parallel-plate capacitor equation is widely used in contemporary material research for nanoscale applications and nanoelectronics. To apply this equation, flat and smooth electrodes are assumed for a capacitor. This essential assumption is often violated for thin-film capacitors because the formation of nanoscale roughness at the electrode interface is very probable for thin films grown via...

Kanemite: an easily prepared and highly efficient catalyst for biodiesel production optimized by response surface methodology

Kanemite was readily prepared and used as solid base catalyst for transesterification of sunflower oil to fatty acid methyl ester (FAME). The catalyst was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), N2 adsorption-desorption and field emission scanning electron microscopy (FESEM) techniques. Central Composite Design (CCD) coupled with Response Surfac...

1 Thin - Film Capacitance

Models for distributed capacitance in a thin lm are derived in the form of a system of local RC diiusion equations coupled by a global elliptic equation. Such models contain the local geometry of the distributed capacitance on which charge is stored and the exchange of current ux on its interface with the medium. Certain singular limits are characterized, and the resulting degenerate initial-bo...
