Continuous Supercritical Water Impregnation Method for the Preparation of Metal Oxide on Activated Carbon Composite Materials
Metal oxide (MexOy) nanomaterials are used as catalysts and/or sorbents in processes taking place in supercritical water (scH2O), which is the “green” solvent needed to obtain energy-relevant products. Their properties are significantly influenced by the s ...
2024New Approach to Synthesis of Tetralin via Naphthalene Hydrogenation in Supercritical Conditions Using Polymer-Stabilized Pt Nanoparticles
Supercritical (SC) fluid technologies are well-established methods in modern green chemical synthesis. Using SC fluids as solvents instead of traditional liquids gives benefits of higher diffusivity and lower viscosity, which allows mass transfer intensifi ...
2020Scanning PIV of turbulent flows over and through rough porous beds using refractive index matching
Christophe Ancey, Gauthier Paul Daniel Marie Rousseau
This paper presents image velocimetry measurements on turbulent flows adjacent to a permeable bed made of randomly packed glass particles. For measuring flow velocities inside the bed, the refractive index of the glass particles was matched with that of th ...
SPRINGER2020Visualization of supercritical water pseudo-boiling at Widom line crossover
Christian Ludwig, Andrea Testino
Supercritical water is a green solvent used in many technological applications including materials synthesis, nuclear engineering, bioenergy, or waste treatment and it occurs in nature. Despite its relevance in natural systems and technical applications, t ...
2019Supercritical water anomalies in the vicinity of the Widom line
Supercritical water is used in a variety of chemical and industrial applications. As a consequence, a detailed knowledge of the structure-properties correlations is of uttermost importance. Although supercritical water was considered as a homogeneous fluid ...
2019Printing of NiO-YSZ nanocomposites: from continuous synthesis to inkjet deposition
Andreas Stephan Lesch, Victor Costa Bassetto, Massimo Rosa
Water-based inks, containing nanometric NiO and YSZ particles in 66/34 vol. % ratio, are produced by colloidal stabilization of a binary dispersion obtained via continuous hydrothermal synthesis at supercritical conditions, i.e. 280 bar and 400 °C. The met ...
2019Production of Additive‐Free Amorphous Nanoparticles with a SAW‐Based Microfluidic Spray‐Dryer
Esther Amstad, Huachuan Du, Mathias Steinacher, Duncan Christophe Emmanuel Gilbert
Spray‐drying is a widely employed, cost‐effective process to formulate solutions into solid particles of controlled sizes and compositions. In addition, this process can also offer control over the structure of spray‐dried particles: if the solvent is evap ...
2019Multiple Inflow Branches at Supercritical-Type Vortex Drop Shaft
Michael Pfister, Jean-Marc Ribi, Corrado Gisonni, Gaetano Crispino, Thierry Fuchsmann
Vortex drop shafts serve to overcome important elevation differences in drainage systems. If well designed, they are performant in terms of energy dissipation and safety. However, the standard design requires well-defined approach flow conditions to ensure ...
