RELATIONS BETWEEN RHEOLOGICAL RESPONSES OF ER FLUIDS TO HIGH AC FIELD AND THEIR NON LINEAR DIELECTRIC PROPERTIES

Acta Physica Sinica, 1997
By measuring the dielectric properties,we have found experimentally that the studied ER fluids underwent interfacial polarization and showed nonlinear dielectric properties under high AC field.Considering the dynamical shear stress to be similar to the high field dielectric spectra of the ER fluids,we have established a relation of dynamical shear ...

Combined sensor of dielectric constant and visible and near infrared spectroscopy to measure soil compaction using artificial neural networks [PDF]

, 2014
Soil compaction is a widely spread problem in agricultural soils that has negative agronomic and environmental impacts. The former may lead to poor crop growth and yield, whereas the latter may lead to poor hydraulic properties of soils, and high risk to

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

Advanced 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 ...

Effect of Deposition Time on the Optoelectronic Properties of CdS Thin Films Synthesized via Chemical Bath Deposition Technique [PDF]

Physics Access
Cadmium sulphide (CdS) thin films were synthesized via chemical bath deposition (CBD) to investigate the influence of deposition time on their optoelectronic properties. The films were deposited at 80 °C for durations ranging from 5 to 30 minutes. Film

Laser‐Induced Graphene from Waste Almond Shells

Advanced 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.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Variable structure model for flow-induced tonal noise control with plasma actuators

, 2008
The objective of this work was to study the effect of plasma actuators in attenuating low-speed flow-induced cavitytones from a control point of view by employing techniques from classical control. A modification of the existingphysics-based linear model
