Over the past years, one of the most important challenges facing industry has been the search for environmentally benign and cost effective alternatives to traditional power sources. Many industries invest considerable ...

The increasing need to replace current materials with new or reprocessed ones that have more specific properties and uses has led to the use of supercritical fluids (SCFs) for polymer reprocessing. Kraton® poly ...

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 ...

This study describes the synthesis and characterization of sulfonated poly(styreneisobutylene- styrene) (SIBS) polymer nanocomposite membranes, which show antibacterial properties useful for the inactivation of Enterococci ...

The rapid growth of the global population, the industrialization and environmental problems caused by global warming have made it necessary to implement advanced water purification techniques capable of fulfilling the ...

In this study, the transport properties of poly(styrene-isobutylene-styrene) (SIBS) block copolymer were determined as a function of sulfonation level (0-94.9 %), counter ion substitution (Ba+2, Ca+2, Mg+2, Mn+2, Cu+2, ...

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 ...

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 ...

This investigation studied the morphology, hydration, and transport properties of different membranes for direct methanol fuel cell (DMFC) applications. First, sulfonated poly(ether ether ketone) (SPEEK) membranes were ...

Organic solar cells are a very promising technology for use in the renewable energy field. Band gap measurements on liquid phase for different polymers were studied, and the possible radiation harvest and reasoning for ...
