The performance of Li-ion battery is known to be dependent on the thickness direction distribution of binder volume fraction. The distribution is determined by drying process of electrode ink, which contains large active material and small binder. With the aim of predicting binder segregation, we studied new drying model of two-particle system solution by considering capillary pressure.

Blood Flow Patterns in a Patient Specific Right Coronary Artery with Multiple Stenoses - new

Atherosclerotic lesions preferentially develop in certain regions like bifurcations, branches, and bends [1, 2]. A possible explanation for such a preferential localization of atherosclerosis is that the geometry of the vessel influences the blood flow pattern. It suggests that the arterial geometry plays an important role in determining the localized blood flow information. Thus hemodynamic ...

Medical Cyclotrons are used in hospitals to manufacture radiopharmaceuticals. The nuclear reaction between the Cyclotron charged particles and a material takes place inside the so-called targets. In particular, gas target is used when a specific gas is bombarded with proton particles to produce radioactive gas [1]. For successful reaction and good production yield, heat generated due to ...

[1] Indian Institute of Technology Indore, Indore, Madhya Pradesh, India

In the present work, we have studied the electron transport properties of single silicon nanowire using Semiconductor Module of COMSOLMultiphysics software. We construct a MSM (metal-semiconductor-metal) model where metal is selected as copper and semiconductor is taken as silicon. Silicon is doped with n-type impurity by increasing doping concentration. Further, the Schottky diodes formed at ...

Lithium-sulphur (Li-S) batteries have the potential to surpass the energy storage capability of Li-ion batteries due to their high theoretical gravimetric energy density of 2700 Wh/kg. However, the processes which drive the system behaviour are much more complex than those in a Li-ion cell, meaning that controlling them to realise energy densities much above 350 Wh/kg is challenging. In a Li ...

[1] Université Pierre et Marie Curie, Paris, France

Electromagnetic and thermal simulations are achieved using COMSOL Multiphysics® with 2D axisymmetrical finite–element method for a percutaneous microwave hyperthermia system with ex–vivo experiments on different biological tissues. Temperature variation and distribution are studied in the biological tissues submitted to an open ended coaxial cable as microwave applicator. Three types of heat ...

[1] CERN, Geneva, Switzerland

A new electrochemical polishing facility will be built at CERN to process copper radiofrequency structures and this in the framework of the Future Circular Collider study. This polishing installation will be designed and assembled so that the necessary working conditions to achieve the ultimate limits of this technique are ensured. The main working variables like potential, current density, bath ...

Simulation and Visualisation of Shielding Gas Flows During Wire-Arc Additive Manufacture

I. Bitharas [1], A. Moore [1],
[1] Heriot-Watt Univerisity, Edinburgh, UK

One of the challenges associated with the wire-arc additive manufacture (WAAM) of metals is to provide adequate inert gas shielding, not only for the molten pool, but also for the long reactive metal surface that follows it. For Ti-6Al-4V, it has been shown that increased levels of porosity, a direct consequence of air contamination, result in reduced structural properties, lower fatigue ...
