Effect of β-PVDF Piezoelectric Transducers’ Positioning on the Acoustic Streaming Flows

open access: yesMicromachines, 2014
This paper reports the numerical and experimental analysis of the acoustic streaming effect in a fluidic domain. The actuation of a piezoelectric transducer generates acoustic waves that propagate to the fluids, generating pressure gradients that induce ...

Normal state Nernst effect, semiconducting-like resistivity and diamagnetism of underdoped cuprates [PDF]

open access: yes, 2005
Semiconducting-like low-temperature in-plane resistivity indicates that there are no remnants of superconductivity above the resistive phase transition at T > Tc in underdoped cuprates.

Modification of Canola Oil Properties Using Ethyl Oleate and n-Hexane

open access: yesEnergies
Canola oil (rapeseed oil, RO), despite being a potential source of biofuel, needs some modifications of its properties to be effectively used as a fuel. The reason RO needs to be altered lies above all in its viscosity, fatty acid composition, and other ...

The Influence of the Ethyl Oleate and n-Hexane Mixture on the Wetting and Lubricant Properties of Canola Oil

open access: yesApplied Sciences
Canola oil (RO) is increasingly being considered as a potential lubricant for various types of abrasive materials. Unfortunately, its properties such as wettability, surface tension (ST), adhesion work and dynamic viscosity do not always meet the ...
