Pseudomonas aeruginosa can be detected in a polymicrobial competition model using impedance spectroscopy with a novel biosensor [PDF]

open access: yes, 2014
Electrochemical Impedance Spectroscopy (EIS) is a powerful technique that can be used to elicit information about an electrode interface. In this article, we highlight six principal processes by which the presence of microorganisms can affect impedance ...

Wide-band modelling of tower-footing grounding systems based on the impulse response measurement [PDF]

open access: yesZbornik Radova: Elektrotehnički Institut "Nikola Tesla", 2019
The tower footing grounding system is of major importance for analysis of the lightning overvoltages on an overhead transmission line during backflashover and shielding failure.

Enhancement of the Through‐Thickness Electrical Conductivity of Carbon‐Fiber‐Reinforced Plastics Using Large Graphite Particles

open access: yesAdvanced Engineering Materials, EarlyView.
To enhance through‐thickness conductivity without sacrificing impregnation, large spherical graphite particles are intentionally employed in a low‐viscosity resin. Unlike finer conductive fillers, these particles remain outside the fiber bundles and accumulate in resin‐rich interlaminar regions during molding.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

open access: yesAdvanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Determining acoustical directionality in an impedance tube using multiple fixed microphones [PDF]

open access: yes, 2011
Acoustic impedance of a port or object is a valuable piece of knowledge describing how well sound is transmitted or reflected. The commonly used slotted-line method is labourious and time consuming, requiring manual movement to find the maxima and minima

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Validation of frequency-varying characteristics of soil electrical parameters and their applicability in impulse response

open access: yes电力工程技术
There is a great difference between the transient response characteristics and the power frequency response characteristics of the grounding device under lightning strike. Its grounding impedance decreases under the action of soil impulse characteristics.

Achieving High ON State Current through Ferroelectric Polarization‐Dependent Interfacial Resistance Switching in Undoped Orthorhombic HfO2 Films

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectric tunnel junction devices based on epitaxial undoped ferroelectric HfO2 films demonstrate stable switching endurance of over 106 switching cycles, low write voltages of ±3 V, 16 measured resistance states, and neuromorphic capability.

Impulsive impedances in lossless circuits: Fourierand Laplace methods

open access: yesElectronics Letters, 2000
A proposal for adding impulsive components of impedance/admittance to the reactance/susceptance for lossless transmission lines is extended to all lossless resonant circuits. This new Fourier analysis yields a finite rate of energy transfer from a lossless source while the orthodox analysis would give an unbounded steady-state energy transfer.
