Toward Sustainable and Cost-Effective CO2 Conversion Processes to Propylene Carbonate Based on Ionic Liquids

Elia Mercedes Ruiz Pachon

The use of ionic liquids (ILs) for CO2 capture and utilization into a valuable product is attracting interest even though literature evaluating their sustainability is scarce. A liquid-liquid extraction (LLE)-based separation is recently proposed as an alt ...

Emergent thermophoretic behavior in chemical reaction systems

Paolo De Los Rios, Daniel Maria Busiello, Shiling Liang

Exposing a solution to a temperature gradient can lead to the accumulation of particles on either the cold or warm side. This phenomenon is known as thermophoresis, and its microscopic origin is still debated. Here, we show that thermophoresis can be obser ...
