In order to assess the potential toxicity of the solvent HFIP, 45,000 hADSCs were cultured per well and different concentrations of HFIP solvent (10, 50, 100, 250, and 500 ppm) in DMEM supplemented with 10% FBS and 1% antibiotic were evaluated.
After 72 h of cultivation of the hADSCs in a culture medium containing HFIP solvent, no statistical difference was observed (P = 0.
The five PLA samples tested in this report took approximately one second to dissolve in hexafluoroisopropanol (HFIP
), whereas the other two fiber types are insoluble in HFIP
2013)] and the University of Wisconsin Nonhydrostatic Model, among others, have been funded by HFIP
(Gall et al.
Under continued HFIP
collaboration, ongoing experimental efforts at NOAA and PSU seek to considerably expand the sample sizes by including other airborne inner-core observations such as those made by the dropsondes, flight-level in situ and remote-sensing measurements from all hurricane reconnaissance flights, as well as through continuously cycled data assimilation that includes routine observations.
We also acknowledge the support of the Office of Naval Research and the NOAA HFIP
for funding this and other efforts to improve tropical cyclone intensity forecasting.
A PL HFIP
gel column (Polymer Lab) and a refractive index detector (Shimadzu RID-10A) were used.
Safety precautions should be taken when handling HFIP
because it is a corrosive solvent that causes burns and irritates eyes and skin.
Previously, PG chitin, dissolved in HFIP
(8) was electrospun into fine, cylindrical, continuous, bead-free, randomly oriented fibrous mats [Refer Appendix for Fourier transform infrared spectroscopy (FTIR) on bulk and electrospun chitin].

The infrared spectra were recorded from measurements on ~ 10 [micro]m thick films that were solvent-cast on a KBr pellet from a solution in HFIP
The desired ratio of polymers was simultaneously dissolved in HFIP
and the solution was allowed to stir for at least 12 hours to ensure complete dissolution and mixing.
