Introduction: After more than 20 years of experience in EV applications, the sodium nickel chloride technology is fully mature for large scale energy storage. Early on, mathematical modeling of Na-MCl2 cell (M standing for Fe or Ni) has attracted attention to help identifying predominant mechanisms at work during operation. However, these models were rarely validated with data coming from ...

On the surface of an optical waveguide, there is an evanescent field. The evanescent field decays fast and this steep gradient can be used to pull nano- and microparticles down towards the waveguide surface. Radiation forces will propel the particle forward along the waveguide. Trapping on an optical waveguide can be used to manipulate particles in a lab-on-a-chip system where optical methods ...

The dependency of electrochemical processes performances on mass transfer is well-known. Electrolyte flow in the vicinity of electrodes surface can enhance reactions due to increased mass transfer. This flow can be generated by the production of a gaseous phase, leading to a natural bubble-driven convection flow. As a drawback, gas bubbles also modify electrodes active surface and the ...

Introduction: RFID system uses a Transponder and the near field communication (NFC) antenna and a matching circuit (Figure-1) in which at least latter two must be optimally designed for a higher efficiency. Typically, RFID antennas are flat inductive coils with 2 to 4 turns and are printed directly on the PCB. The larger antenna size implies larger operating distance whereas, the number of ...

The high luminosity large hadron collider (HL-LHC) project aims at increasing the integrated luminosity by a factor of 10 from its original value (from 300 to 3000 fb-1) leading to the potential extension of scientific discoveries. To attain this goal, important upgrades will take place in the LHC by 2024 including the installation of new superconducting magnets in which new beam screens will be ...

Introduction Droplet-based microfluidics is a large source of research for scientists of new biotechnologies, aerosols or other 2D-Microfluidics devices. Here, we will focus on an industrial application of a 3D microfluidic device : the PH2DG, Pneumo-HydroDynamic Droplet Generator. The aim of the process is to produce mono-disperse, regular pattern of droplets, with a minimum size. To use it in ...

In inductive heating simulations the electromagnetic properties of the steel have a significant impact on the temperature pattern along the heated product. Indeed, taking into account the non-linearity of the ferromagnetic material properties is a key point to have relevant simulation results. In particular, it is important to correctly include the nonlinear relationship between the magnetic ...

In order to predict the residual mechanical state of assemblies during pulsed laser welding, mechanical and metallurgical behaviors of materials need to be precisely characterized. Based on experimental data and analyses , a numerical model is developed in COMSOL Multiphysics® software to take into account the predominant effects identified for TA6V. First of all, the metallurgic behavior ...

Introduction: The drawbacks of most commercial “advanced battery” solutions are high price, danger, and low recyclability. The most cost efficient, environmental-friendly, and safest solutions so far is based on lead-acid electrochemistry, a proven technology for more than 150 years. Key problems of this technology are however the limited cyclability which results in a reduced lifetime and high ...

Intervertebral discs (IVD) are fibro-cartilages situated between vertebrae providing their joint flexibility. They play a major role in the transmission and absorption of load through the spine. The disc can undergo progressive structural and quantitative changes in its composition and morphology related to mechanical load applied to the spine which can lead to disc degeneration; this disease is ...
