New material opens up the possibility of saving up to 80 percent of energy when separating raw materials for the plastics industry

14-Aug-2020

Jointly with cooperation partners, a researcher of Karlsruhe Institute of Technology (KIT) has developed “porous liquids”: Nanoparticles, that are able to separate gas molecules of different sizes from each other, float – finely distributed – in a solvent. This is because the particles have empty ...

Polyimide membranes for the purification of natural gas

26-Jun-2020

Natural gas that contains larger amounts of hydrogen sulfide (H2S) and carbon dioxide (CO2) is termed sour gas. Before it can enter a pipeline, it must be “sweetened” by removal of its acidic impurities. Through fine tuning of the ratios of two molecular components, it is possible to produce ...

The electrical charge is what makes the difference

05-Mar-2020

A new membrane developed at the Helmholtz-Zentrum Geesthacht (HZG) separates small dye particles or drug substances not only by size but also by their electrical charge. This additional function enables organic molecules with lateral dimensions of one to two nanometres to be such high-efficiently ...
