Dielectric spectroscopy study on ionic liquid microemulsion composed of water, TX-100, and BmimPF6.
We report here a broadband dielectric spectroscopy study on an ionic liquid microemulsion (ILM) composed of water, Triton X-100 (TX-100), and 1-butyl-3-methylimidazolium hexafluorophosphate (bmimPF(6)). It is found that the phase behavior of this ILM can be easily identified by its dielectric response. The dielectric behavior of the ILM in the GHz range is consistent with that of TX-100∕water m...
متن کاملEffect of water on interfacial chemical properties of nonionic surfactants in hydrophobic ionic liquid bmimPF6.
We studied the effect of water addition on interfacial properties and aggregate behavior of nonionic surfactants (polyoxyethylene alkyl ether; CnEm) in an ionic liquid (1-butyl-3-methylimidazolium hexafluorophosphate; bmimPF₆). When a small amount of water was added to mixtures of CnEm and bmimPF₆, two breaking points (cac1, cac2) were observed in the surface tension/CnEm concentration plots, s...
متن کاملPolylactic acid (PLA)
This website provides an excellent overview of PLA as a polymer, its properties, and manufacture. This web article describes the production of lactic acid from biomass by microbial fermentation coupled to a poly-merization process to make PLA. The article is a bit dated and its industrial projections are now seen to be a bit over-optimistic. NatureWorks is the company that started large-scale p...
متن کاملApplication of a novel approach to prepare biodegradable polylactic-co-glycolic acid microspheres: surface liquid spraying.
A novel approach which had foreground of industrialization, surface liquid spraying, was studied in this paper to prepare biodegradable polylactic-co-glycolic acid (PLGA) microspheres for controlled release drug delivery system. To compare with the normal methods, the microspheres prepared by this approach were characterized by particle size distribution and photograph of microscope. The relati...
متن کاملSpectroscopic studies of amino acid ionic liquid-supported Schiff bases.
Amino acid ionic liquid-supported Schiff bases, derivatives of salicylaldehyde and various amino acids (L-threonine, L-valine, L-leucine, L-isoleucine and L-histidine) have been investigated by means of various spectroscopic techniques (NMR, UV-Vis, IR, MS) and deuterium isotope effects on ¹³C-NMR chemical shifts. The results have shown that in all studied amino acid ionic liquid-supported Schi...
