Since more than 100 years, the adsorption of the radioactive noble gas radon (222Rn) is performed on activated charcoal at cryogenic temperatures. There is little-if any-progress in the field of radon adsorption at ambient conditions to facilitate the development of simple and compact radon adsorption systems. We report here on the truly remarkable...
Molecular dynamics simulations were performed to elucidate the roles of ion structure and interface behavior in absorption of gases (NH3, N-2, H-2) by ILs (protic IL [Bim][Tf2N] and conventional IL [Bmim][Tf2N]). The results indicated that NH3 compete with [Tf2N](-) to interact with N3-H site of [Bim](+) cation, forming a strong N3-H center dot cen...

High-order harmonic generation (HHG) is a fundamental process which can be simplified as the production of high energetic photons from a material subjected to a strong driving laser field. This highly nonlinear optical process contains rich information concerning the electron structure and dynamics of matter, for instance, gases, solids and liquids...
The study of phases is useful for understanding novel states of matter. One such state of matter are time crystals which constitute periodically driven interacting many-body systems that spontaneously break time translation symmetry. Time crystals with arbitrary periods (and dimensions) can be realized using the model of Bose-Einstein condensates b...
Afin d’anticiper de potentiels problèmes thermiques liés à l’éjection de gaz d’échappements à haute température par les moteurs hélicoptères, les industriels ont de plus en plus recours à la simulation numérique. La simulation de la trajectoire et du mélange des gaz d’échappement est cependant complexe et peu intuitive. Elle implique notamment de r...
The interaction of Aun+ (n ≤ 20) clusters with Ar is investigated by combining mass spectrometric experiments and density functional theory calculations. We show that the inert Ar atom forms relatively strong bonds with Aun+. The strength of the bond strongly varies with the cluster size and is governed by a fine interplay between geometry and elec...
In this study, magnetic steel slag biochar (MSSB) was synthesized from low-cost steel slag waste to investigate the effectiveness of steel slag biochar composite for NH4-N removal and magnetic properties in aqueous solution. The maximum adsorption capacity of NH4-N by MSSB was 4.366 mg/g according to the Langmuir model. The magnetic properties of M...
The analysis of the influence of various design solutions of the gas-dynamic stabilization system in plasma torches for cutting metals on the efficiency of equalizing the velocities of gas flows along the cross-section of the gas path is carried out. It is noted that the efficiency evaluation method developed by the authors should be based on the c...
