A study on synergies of combined pulp and fuel production

François Maréchal, Julia Granacher, Tuong-Van Nguyen

To limit climate change by reducing global greenhouse gas emissions, a transition away from fossil fuels is required. Biofuels represent a promising low carbon alternative for sectors that are hard to electrify, such as aviation. The integration of bio ref ...

Synergistic Cu/CeO2 carbon nanofiber catalysts for efficient CO2 electroreduction

Andreas Züttel, Wen Luo, Jie Zhang

The electrochemical reduction of carbon dioxide (CO2RR) has attracted enormous interest because of the energy crisis and climate change; however, more efficient catalysts are required for practical applications. Herein, we present electrospinning as a faci ...

Decarbonization in Complex Energy Systems: A Study on the Feasibility of Carbon Neutrality for Switzerland in 2050

François Maréchal, Stefano Moret, Xiang Li, Theodoros Damartzis

Decarbonization gained prominence with the witnessed rise of temperature over recent years, particularly in the aftermath of the adoption of the Paris agreement for limiting the temperature increase within 2°C until 2050. Biogenic resources are explicitly ...

Characterization of metal organic frameworks of interest for gas adsorption/separation applications

Mehrdad Asgari

Metal-Organic Frameworks (MOFs) are a class of porous materials that are applicable in many energy and environmentally relevant areas, due to their unique features including unprecedented internal surface areas and easy chemical tunability. Gas separation ...

Carbon dioxide reduction by lanthanide(iii) complexes supported by redox-active Schiff base ligands

Rosario Scopelliti, Marinella Mazzanti, Nadir Jori, Davide Toniolo

Here we have explored the ability of Schiff bases to act as electron reservoirs and to enable the multi-electron reduction of small molecules by lanthanide complexes. We report the reductive chemistry of the Ln(iii) complexes of the tripodal heptadentate S ...

Visualization 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 ...

Palladium-Catalyzed Carboxy-Alkynylation of Propargylic Amines Using Carbonate Salts as Carbon Dioxide Source

Jérôme Waser, Phillip Gulliver Dominic Greenwood

A palladium-catalyzed multicomponent reaction of propargylic amines, alkynyl bromides and cesium hydrogen carbonate to access oxazolidinones is reported. In contrast to previous reports, only a slight excess of cesium hydrogen carbonate is used as a surrog ...

Supercritical water anomalies in the vicinity of the Widom line

Christian Ludwig

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 ...
