Block copolymers prepared from isocyanate-terminated polybutadiene (NCOPBER) resulted in cured transparent epoxy networks with no discernible phase-separated morphology, as indicated by scanning electron microscopy.
The AFM findings support the earlier studies and reveal a remarkable level of long-range coherence in the chain direction with few regions of imperfection consisting mostly of isolated molecular kinks, flip-over of molecules and gradual coherent twists, but no readily discernible phase-separated amorphous layers.
In addition, SEM clearly shows the three discernible phases in the alloys with low purity Gd; EDS analyses have been conducted on all of them.
We identified four discernible phases of policymaking in relation to pesticide regulation from 1960 to 2005.
Antigen-induced arthritis (AIA) in the rat [ 15], a severe knee monoarticular arthritis induced by intra-articular administration of methylated bovine serum albumin (mBSA) after systemic immunization, is a suitable arthritis model inasmuch as CD4+ T cells and macrophages infiltrate the SM [ 16] and its course consists of clearly discernible phases.
Phase separation temperatures were measured turbidimetrically and by determining the first discernible macroscopic phase separation.
This strong refringence as seen by dark field microscopy is probably due to the optically dense walls of these particles, which also make the same particles easily discernible by phase contrast microscopy in the absence of any staining (not shown).
For example, on the one hand, we had recordings with very short or almost no discernible inspiratory phases, and on the other hand, we had recordings which have unusually prominent inspiratory phases as compared to expiratory phases.
NHL games exhibit no discernible end-phase pattern in their intermediate periods (1 and 2), but show an enormous end-game effect, with the scoring rate growing to more than three times its game mean.
Cell division in pre-MBT embryos alternates rapid rounds of DNA synthesis and mitosis (∼20 30 min) with no discernible G phases [56], [57].
