Atomic force microscopy (AFM) has been widely recognized as an essential tool that enables the imaging of surface, measuring and localizing many different forces and becoming a standard technique for force spectroscopy at the nanoscale. While conventional AFM is well-developed, recent ... En savoir plus

New design structure for generating and tuning the multi-bands of negative modulus is presented by introducing metamaterial concept. To effectively achieve selective noise reduction and sound transmission, acoustic metamaterial consisted of arrayed multiple resonators with extended necks ... En savoir plus

RAKON is a worldwide expert in high performance crystal oscillator. The company decided to expand its product range to larger space equipment, the Master Reference Oscillator (MRO). This product is composed of stacked mechanical modules, joined together by structural screwed assemblies. ... En savoir plus

Bentonite is a versatile material that is, among other things, envisaged in most countries worldwide for use in radioactive waste repositories to protect the waste canisters against groundwater. The thermo-hydro-mechanically (THM) coupled process of bentonite saturation is commonly based ... En savoir plus

For modeling battery simulation, material properties and simulation parameters such as electrical conductivity, diffusion coefficient, volume ratio of electrodes / electrolytes, exchange current density and electrode particle radius are required. Though these kinds information can be ... En savoir plus

High-voltage power cables are vital components of power transmission systems. Submarine cables are critical power carriers between offshore wind farms and onshore ac grids. Moreover, underground cables are generally preferred over overhead installations in land applications, owing to ... En savoir plus

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
