Abstract Consecutive layers of Ni(OH) 2 and Co(OH) were electrodeposited on stainless steel current collectors for preparing charge storage electrodes high specific capacity with potential application in hybrid supercapacitors. Different prepared consisting films , Ni 1/2 Co (OH) layered to highlight the advantages new architecture. The microscopy studies revealed formation nanosheets particles agglomerates films. Important morphological changes observed double hydroxides Film growth by...

This work reports the fabrication, by electrodeposition and post-thermal annealing, of hybrid electrodes for high rate electrochemical energy storage composed nickel manganese oxide (Ni0.86Mn0.14O) nanosheets over 3D open porous dendritic NiCu foams. The are made two different percolation networks dendrites, exhibit a specific capacitance value 848 F g−1 at 1 A g−1. tests revealed that display an excellent capability, characterized retention approximately 83% when applied current density...
The initial growth stages nickel cobalt hydroxide films prepared by electrodeposition for energy storage applications.
Experimental measurements were conducted to study the problem of crosstalk in multilayer printed-circuit-board design. Experiments using both pulse and sinusoidal signals designed as a function coupling line lengths, spacings, shielding versus nonshielding (lines different layers). The mutual inductance capacitance between two similar transmission lines also extracted from simple models crosstalk. It is found that when sinusoid-driven signal was used voltage source, coupled acted...

This paper presents a method based on multipoint Pade approximation in conjunction with the of characteristics for reduced order modeling and simulation coupled multiconductor transmission lines (MTL) frequency dependent losses. Specifically, skin-effect loss associated conductors is primary concern. Recursive algorithms generate sets frequency-shifted moments used approximation. The approach provides accurate broadband transfer function characteristic admittance. time accomplished via...

It has impacts on many aspects of modeling, simulation and analysis, presents some unique challenges due presence number electrical phenomena SOI.In this tutorial, we will review technology, touching specifically devices models, as well impact floating body parasitic bipolar effects. We show examples these circuit behavior balance that against existing sources variation such power supply variations,...
This paper presents a general method for incorporating state transformation in event driven explicit simulation. One inherent assumption this type of simulation algorithm is the independence, which allows to process states independently an manner at transistor level. Numerical problems arise when inappropriate representation circuit, are not truly independent, chosen. In principle, any similarity equation can be employed transform circuit into more convenient space numerical solution....
