Thermal and mechanical properties of PU/POSS nanocomposites plasticized with DOA were investigated. These hybrid materials were prepared using one-step method through the incorporation of flexible HTPB prepolymer, reactive or non-reactive POSS nanoparticle, and DOA plasticizer under IPDI curative system. The

Diffusion tensor imaging (DTI) was used to study traumatic brain injury. The impact-acceleration trauma model was used in rats. Here, in addition to diffusivities (mean, axial and radial), fractional anisotropy (FA) was used, in particular, as a parameter to characterize

[M + Ag](+) ions from cyclic and linear polystyrenes and polybutadienes, formed by matrix-assisted laser desorption ionization (MALDI), give rise to significantly different fragmentation patterns in tandem mass spectrometry (MS(2)) experiments. In both cases, fragmentation starts with homolytic cleavage at

Blue light-emitting Au nanoclusters were synthesized in a simple one-pot process via reflux of Au ions with amino-terminated poly(1,2-butadiene) in toluene. DLS results and photoemission spectra showed that Au(8) nanoclusters were successfully formed. Moreover, photo-patterned films containing Au(8) clusters were

We present the results of coarse grained molecular dynamics simulation using a charge free model that is able to capture different regions of the morphological phase diagram of charged diblock copolymers. Specifically, we were able to reproduce many phases of
