Scanning Impedance Microscopy: From Impedance Spectra to Impedance Images [PDF]

open access: yesMicroscopy Today, 2001
Abstract The properties and performance of electronic devices are crucially dependent on interface-related phenomena. The presence of interfaces can enable electronic device functionality (p-n diodes, solar cells); alternatively, non-functional interfaces can degrade device performance (ohmic vs. non-ohmic contacts).

Recycling of Li−Ni−Mn−Co Hydroxide from Spent Batteries to Produce High‐Performance Supercapacitors with Exceptional Stability

open access: yesChemElectroChem, 2020
The intensive implementation of Li‐ion batteries in many markets makes it increasingly urgent to address the recycling of strategic materials from spent batteries. Batteries typically contain toxic chemicals and cannot be disposed of at will.

On the Passivity Based Impedance Control of Flexible Joint Robots [PDF]

open access: yes, 2008
In this paper, a novel type of impedance controllers for flexible joint robots is proposed. As a target impedance, a desired stiffness and damping are considered without inertia shaping.

Evaluation of Hepatoprotective Effect of Curcumin on Liver Cirrhosis Using a Combination of Biochemical Analysis and Magnetic Resonance-Based Electrical Conductivity Imaging

open access: yesMediators of Inflammation, 2018
In oriental medicine, curcumin is used to treat inflammatory diseases, and its anti-inflammatory effect has been reported in recent research. In this feasibility study, the hepatoprotective effect of curcumin was investigated using a rat liver cirrhosis ...

Multifrequency dielectric mapping of fixed mice colon tissues in cell culture media via scanning electrochemical microscopy

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
Alternating current scanning electrochemical microscopy (AC-SECM) is a powerful tool for characterizing the electrochemical reactivity of surfaces. Here, perturbation in the sample is induced by the alternating current and altered local potential is ...

Acoustic Vector-Corrected Impedance Meter [PDF]

open access: yes, 2014
We describe the development of a novel instrument intended for the measurement of the acoustical reflection coefficient of materials. The instrument effectively implements a one-port vector-corrected network analyzer in the acoustic, rather than the ...

Setpoint Feasibility and Stability of Wind Park Control Interactions at Weak Grids

open access: yesJournal of Modern Power Systems and Clean Energy, 2022
The controllers of wind parks that are connected to weak grids can induce unstable oscillations near the fundamental frequency. Such phenomenon can be studied with equivalent impedances of the wind generators, which depend on their operational setpoints ...

A FOUR TERMINAL AXIAL-BISHIELDED NETWORKS

open access: yesТехнічна електродинаміка, 2022
An impedance measurement object with an H-shaped four-terminal equivalent substitution circuit is considered. An error analysis was performed for sensors whose non-informative supply resistances are of the same order or exceed the measured impedance.
