Sulfonated fluoroblock copolymer membranes for direct methanol fuel cell applications
This investigation studied the transport properties of several fluorinated sulfonated membranes for direct methanol fuel cell applications. First, Nafion® membranes were processed with supercritical fluid (SCF) CO2 and ...
Reverse micelles in supercritical carbon dioxide for pharmacological applications: a spectroscopic characterization
The aim of this research is to characterize microemulsions in supercritical (sc) CO2 using two spectroscopic techniques (UV-Vis and FT-IR) and apply the microemulsion approach to extract impurities from a pharmacological ...
Transport properties of proton-exchange membranes: effect of supercritical-fluid processing and chemical functionality
Nafion® membranes commonly used in direct methanol fuel cells (DMFC), are tipically limited by high methanol permeability (also known as the cross-over limitation). These membranes have phase segregated sulfonated ionic ...
