Elastomeric elements are currently used as external dampers in many applications to increase the stability of dynamical systems, e.g., rotor-bearings systems. However, the dynamic design of systems embedded with elastomeric dampers is a hard task, since the properties of this kind of ... En savoir plus
In this work we present a novel approach to enhance energy efficiency in cooling intake air for air conditioning (AC) systems in harsh environments using geothermal energy. We developed a 3D finite element model to simulate the heat transfer between underground soils/gravels and cooling ... En savoir plus
Roll-to-plate nanoimprinting is a manufacturing method to replicate micro- and nanotextures on large-area substrates with UV-curable resins. Figure 1 shows a schematic of the roll-to-plate imprint process, which is considered in this study [1]. It uses several rollers, for imprinting and ... En savoir plus
Electrochemical Impedance Spectroscopy (EIS) is a technique commonly used to investigate the properties of the electrode surface and the bulk electrolyte in an electrochemical cell [1]. An AC excitation signal is applied with a frequency range, typically from 0.01 Hz to 1 MHz, and the ... En savoir plus
