The photo-DSC profiles of the photopolymerization of HEA initiated by different initiating systems are presented in Fig.
Figure 3 shows the photo-DSC profiles of the photopolymerization of HEA initiated by different initiating systems containing the above amino acid and pentapeptides, respectively.
This suggested that the condensation polymerization of the amino acid with excellent photo-initiating capability was unfavorable for further improving initiating efficiency.
It can be seen that the hydrogel films initiated by these two initiating systems all exhibit excellent mechanical tensile strength.
And by investigating the photo-initiating ability of four essential amino acids of silk peptide, glycine, alanine, serine, and tyrosine, respectively, it was found that glycine and alanine exhibited excellent initiating activity.
Moreover, the water absorption of the photo-curing hydrogel initiated by the initiating system containing SP, was further improved, due to excellent hydrophilicity of SP.
Photo-DSC profiles for the photopolymerization of HEA initiated by the initiating systems containing four essential amino acid or pentapeptides, respectively as well as by CQ/IOD and CQ/SP/IOD, respectively, under the visible light with an intensity of 30 mW/[cm.sup.2]; in systems, the concentration of the sensitizer was 0.5% (w/w) and every components were mixed in 1:1 weight ratio.
8) Can new and/or better in viva functional assays to identify tumor initiating
cells (e.g., engraftment of leukemic stem cells into immunodeficient NOD/SCID mice) be developed?
Precisely because libel suits can be so expensive, there are, needless to say, semi-scrupulous lawyers who specialize in conning rich people into initiating them.
It is obvious that anyone initiating a libel suit, anyone so desperately desiring assault weaponry, is courting the ignominy that is generally accorded bullies.
