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 ...

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 ...

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 ...

Solubility data for pharmacological drugs in supercritical fluids (SCFs) is of great importance, because there is an environmental and cost effective need for alternative specialty separation methods. This research was ...

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 ...

Currently, supercritical-fluid technology in the pharmaceutical and microelectronics industries is increasingly applied to solve difficult processing problems. The solubility of a solute in the supercritical fluid is the ...
