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 ...
Surface modification of nanoporous films using organosilanes dissolved in supercritical carbon dioxide
It is well known in the microprocessor industry that as the number of transistors increases, the capacity of chips to manage information also increases. To continue with the increment in the number of transistors per ...
