The Triton team was contracted to model and optimize a gas separation/pre-concentrator system involving selectively permeable membranes. The system would nominally include an input of mixed gas species at some driving pressure, a number of membrane modules, and separate permeate ... En savoir plus

The synthesis of the superheavy elements and investigations of their nuclear, atomic and chemical properties are at the scientific forefront. Experiments are challenging due to the extremely low production rates and short half-lives [1]. A new universal high-density gas stopping cell ... En savoir plus

Founded in 1959, with headquarters in Aalst-Waalre, the Netherlands, and having approximately 140 employees, Goudsmit Magnetics is a specialist in the field of magnets and magnetism and delivers both standard and custom-made permanent and electro-magnet solutions in various fields, ...

A defining characteristic of atomic layer deposition (ALD) is the sequential exposure of a surface to self-limiting, saturating reactions. Temporal ALD operates through intermittent purge cycles, while spatial ALD relies on physical separation accomplished by delivering reactants through ... En savoir plus

This study investigates the shock boundary layer interaction occurring at the base of a double sharp fin. The base geometry is of particular interest, with comparisons made between flat and semi-cylindrical bases. The flow field is characterized via numerical simulations and ... En savoir plus

Photoacoustic spectroscopy (PAS) enables highly sensitive gas detection without optical detectors by directly measuring the sound generated from light absorption. However, the performance of PAS systems strongly depends on the photoacoustic cell’s acoustic design. In this work, we ... En savoir plus

Noble gasses such as argon and helium are utilized within In Gas Laser Ionization and Spectroscopy (IGLIS) [1] and Ion Guide Isotope Separation On-Line (IGISOL) [2] techniques to thermalize and transport the nuclear reactions products, which often have short lifetimes and small ... En savoir plus

In the nuclear fuel industry, the dry conversion process is employed to transform crystalline UF6 to UO2 powder, in order to produce fuel pellets. The quality of the finished product highly depends on the process input parameters, and it is imperative to understand accurately the full ... En savoir plus

The current and energy transfer to cathodes of vacuum arcs usually occurs in bright, narrow regions, known as cathode spots. Owing to extreme conditions in these spots, the cathode surface is eroded: electrode material is vaporized, and craters and molten metal jets are formed. The study ... En savoir plus

Aqueous polymers used for enhanced oil recovery (EOR) application is considered a complex fluid. It can exhibit Newtonian and Non-Newtonian behavior depending on the velocity or the stresses that it is submitted during the flooding process. Therefore, the polymer flooding project ... En savoir plus
