Multi-objective Optimization of Supercritical Water Gasification of Leftover Brazilian Ginseng Roots After Phytochemical Recovery Steps

François Maréchal, Adriano Viana Ensinas, Alberto Mian, Juliana Queiroz Albarelli, Diego Tresinari dos Santos

The present study aims at studying the supercritical water gasification (SCWG) of the leftover Brazilian ginseng roots after phytochemicals extraction for synthetic natural gas (SNG) production, envisioning the development of a promising Brazilian ginseng ...

Fluid thermodynamics control fault heating and weakening under upper crustal stress conditions

Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Mateo Alejandro Acosta

Although fluids are pervasive among tectonic faults, thermo-hydro-mechanical couplings during earthquake slip remain unclear. In particular, fluid induced seismicity is today a subject of major interest for the geo-energy community. We report full dynamic ...

Fabrication of 2d Material Based Resonators

Tom Larsen, An Tran

Improvements in manufacturing processes inspired by the semiconductor integrated circuit industry have seen a sharp reduction in dimensions of microelectromechanical systems (MEMS), leading to the emergence of its submicron counterpart – nanoelectromechani ...

Fabrication of 2D Material Based NEMS Resonators

Tom Larsen, An Tran

2D materials such as graphene, MoS2 and phosphorene are promising candidates for resonating mechanical sensors due to excellent tunable electrical/- mechanical properties, low masses, and maximal surface to volume ratios. Mechanical resonators based on sup ...

Catalytic supercritical water gasification: Interaction of sulfur with ZnO and the ruthenium catalyst

Christian Ludwig, Frédéric Vogel, Gaël Peng

Continuous catalytic supercritical water gasification (CSCWG; 400 degrees C, 28 MPa) of microalgal biomass (Chlorella vulgaris) was carried out at the microalgae production site of ZHAW in Wadenswil (Switzerland) non-stop over a period of 100 h. Characteri ...

Can we approach the gas-liquid critical point using slab simulations of two coexisting phases?

Dominic John Tildesley

In this paper, we demonstrate that it is possible to approach the gas-liquid critical point of the Lennard-Jones fluid by performing simulations in a slab geometry using a cut-off potential. In the slab simulation geometry, it is essential to apply an accu ...

Photocatalytic and Electrocatalytic Reduction of Carbon Dioxide in Pressurized Systems

Patrick Voyame

The depletion of carbon-based fossil fuels and the rise in atmospheric carbon dioxide concentration will force an inevitable change in the future global energy landscape. CO2 reduction presents the advantages of decreasing its atmospheric concentration and ...

Cutting the cost of carbon capture: a case for carbon capture and utilization

Berend Smit, Johanna Maria Huck, Lennart Joos

A significant part of the cost for carbon capture and storage ( CCS) is related to the compression of captured CO2 to its supercritical state, at 150 bar and typically 99% purity. These stringent conditions may however not always be necessary for specific ...
