A New Method for Mixed Matrix Composite Membranes Preparation Using Direct Spray‐Coating Technique
Greenhouse Gases: Science and Technology, EarlyView.ABSTRACT The development of membranes has evolved over the last years as an effective CO2 separation technology to fight the environmental impact of post‐combustion processes. In this regard, the upgrade of conventional polymers has been approached through different strategies to overcome their permeance‐selectivity trade‐off.

Terminology for Membrane Distillation [PDF]
, 1989 One of the subjects of the “Round Table ” at the “Workshop on Membrane Distillation ” in Rome on May 5,1986 was nomenclature. The best example for the need of a more uniform language is the name of the process itself.
