  2. Serial Peripheral Interface - Wikipedia

    en.wikipedia.org/wiki/Serial_Peripheral_Interface

    This configuration only requires a single CS line from the main, rather than a separate CS line for each sub. [ 7 ] In addition to using SPI-specific subs, daisy-chained SPI can include discrete shift registers for more pins of inputs (e.g. using the parallel-in serial-out 74 xx165) [ 8 ] or outputs (e.g. using the serial-in parallel-out 74 ...

    en.wikipedia.org/wiki/Randles_circuit

    In a simple situation, the Warburg element manifests itself in EIS spectra by a line with an angle of 45 degrees in the low frequency region. Figure 2 shows an example of EIS spectrum (presented in the Nyquist plot) simulated using the following parameters: R S = 20 Ω, C dl = 25 μF, R ct = 100 Ω, A W = 300 Ω•s −0.5.

  7. Covalent radius - Wikipedia

    en.wikipedia.org/wiki/Covalent_radius

    The covalent radius, r cov, is a measure of the size of an atom that forms part of one covalent bond.It is usually measured either in picometres (pm) or angstroms (Å), with 1 Å = 100 pm.

  8. Mott–Schottky plot - Wikipedia

    en.wikipedia.org/wiki/Mott–Schottky_plot

    Mott–Schottky plot of a fluorine-doped tin oxide (FTO) semiconductor electrode measured in aqueous electrolyte at different pH, with respect to standard Ag/AgCl electrode. Changing the pH modifies the apparent flatband potential by 570 mV corresponding to a 59 mV displacement per unit of pH.

  9. Nichols plot - Wikipedia

    en.wikipedia.org/wiki/Nichols_plot

    The Nichols plot is a plot used in signal processing and control design, named after American engineer Nathaniel B. Nichols. [ 1 ] [ 2 ] [ 3 ] It plots the phase response versus the response magnitude of a transfer function for any given frequency, and as such is useful in characterizing a system's frequency response .
