Introduction: Modeling biological structures is challenging due to their often complex anatomical geometries and material properties. Finite element studies of the femur, the largest and strongest bone in the human body, have focused on the femoral neck, since this is where fractures ... En savoir plus

Solid-state batteries have emerged as a viable alternative to traditional liquid-based lithium-ion batteries, offering improved cost efficiency, safety, and environmental impact. Chlorine-rich lithium argyrodite (Li6PS5Cl) has emerged as a promising solid-state electrolyte, presenting ... En savoir plus

We present a problem-adapted finite element model, which enables the design of a novel type of a highly miniaturized, electrostatic MEMS membrane pump, as well as the investigation and the optimization of its operation. The electro-mechanical actuation scheme constitutes a strongly ... En savoir plus

During the hot extrusion process, a cylindrical pre-heated billet is inserted into a container and is forced by a hydraulic press to flow through a shaped die in order to obtain, as final product, a profile with a constant cross-section (Fig.1). Aluminum extrudates have become prominent ... En savoir plus

Foam is a multiscale material composed of many millimetric cells. Altogether, the cells can easily be shaped into almost any object of the metric scale, provided that a mould is available to let the initial mixture expand appropriately. While some mechanical properties such as foam ... En savoir plus

Thermal ablation driven by an acoustic heat source has tremendous potential for the treatment of diseased tissue. In many applications, such as treating tumors in the liver, bulk removal of tissue is required, and thermal ablation can reliably cause necrosis for a relatively large tissue ... En savoir plus

The intestine, a muscular, tubular organ within the digestive system is responsible for the final stages of food processing. The cyclic material transport generates a shear stress on the intestinal lining known as epithelium. Recently, the application of shear stress on epithelial cells ... En savoir plus

This article reports the design of a high-power ultrasound system, capable of emitting acoustic radiation at 20kHz with SPL peaks up to 160dB at a distance of up to 1m. The main problem of high power airborne ultrasonic systems lies in the acoustic impedance mismatch between the radiator ... En savoir plus

Due to particle interactions, magnetic particles suspended in non-magnetic fields tend to form chains, clusters or columns under magnetic fields. The non-spherical magnetic particles in the suspension show different rheological properties compared to spherical particles. In this paper, ... En savoir plus

In India, more than 150,000 people are killed each year in traffic accidents, according to the Ministry of Road Transport and Highways 2016 report. That’s about 400 fatalities a day, which is far higher than in developed auto markets like the US which, in 2016, logged about 40,000 a ... En savoir plus
