Metal foams are interesting materials with many potential uses. They are characterized by a cellular structure represented by a metal (or a metal alloy) and gas voids inside. A common metallic cellular material is a solid sponge, also known as open-cell metal foam. Due to their intrinsic ... En savoir plus

The rise in atmospheric CO2 needs the development of efficient conversion technologies. CO2 reduction reaction (CO2RR) emerges as a compelling solution, offering the transformation of CO2 into more energetic compounds, such as fuels (hydrocarbons, alcohols, etc.) and valuable chemicals, ...

The disposal of highly radioactive waste in geological environment is not the possibility studies anymore as the countries such as Finland, Sweden, France with more advanced radwaste disposal programs are actually implementing it nowadays. In such disposal system, passive safety does not ... En savoir plus

The continuous inkjet technology is widely used in the industry for marking and coding, and reposes on the emission of charged droplets at high velocity and high frequency. The shape of the droplets and the length needed for the jet breakup are important indicators when designing a ... En savoir plus

The lithospheric mantle often undergoes enrichment in incompatible chemical elements during ocean closure and collisional orogeny. This enrichment is most pronounced during the subduction of sedimentary rocks and crystalline crust derived from continents. Uranium and thorium are ... En savoir plus

A robust and computationally efficient homogenization approach, grounded on exact local and integral moments, is proposed to investigate the temporal evolution and asymptotic properties of the effective velocity vector and the dispersion tensor in Hydrodynamic Chromatographic Columns ...

X-rays represent high-energy electromagnetic radiation capable to penetrate matter and are therefore widely used in medical diagnostics, material testing and various other applications. They are typically produced by vacuum tubes with electrons emitted from a hot cathode and accelerated ... En savoir plus

In order to facilitate semiconductor production in the upcoming technology nodes (3nm, 2nm, 14A) our state-of-the-art multi beam mask writer (MBMW) needs constant improvement in throughput and writing precision. As these two goals contradict each other, adaption of the electron optical ... En savoir plus

Temperature homogeneity is a critical issue for high temperature vacuum furnaces for heat treatment, as small temperature variations in the load volume can significantly influence the heat treatment result. It is generally defined by the so-called Temperature Uniformity Survey (TUS) ... En savoir plus

Axial-flux permanent-magnet motors are an important technology in many technical applications, being an alternative to radial-flux motors. Axial-flux motors come up with many advantages in comparison to radial-flux motors such as high-power density, higher torque to weight ratio etc. ... En savoir plus
