To fully understand the polymer-filler interfacial interaction mechanism, we use a coarse-grained molecular dynamics simulation to mainly investigate the interfacial dynamic properties by tuning the polymer-filler interaction, temperature, chain length, volume fraction of filler, and size and shape of filler. The polymer beads around the filler exhibit an obvious layering behavior and a gradien...

INTRODUCTION: Vertebral fractures are often the result of a progressive deformation process. Structural brittleness parameters should be considered relevant for such failure processes. Much of the previous work has been concerned with vertebral stiffness and strength but measures of brittleness such as work to fracture and failure displacement largely remained unexplored. In a previous study ex...

The polymer-filler interaction of a dental composite was examined by dielectric measurements to determine how a non-compatible inorganic phase modifies the molecular behaviour of the polymer chains and how modification of this phase by silanation can affect these molecular behaviours. Urethane dimethacrylate (UDMA) monomer and zirconia-silica (ZS) powder were used as organic and inorganic phase...

INTRODUCTION Polyacrylamide hydrogel has been considered a safe and biocompatible soft tissue filler, and it has been widely used in cosmetic procedures. However, recent studies have revealed some complications with polyacrylamide filler injections. CASE REPORT We present the case of foreign-body granulomas of the glabella, which subsequently formed an infectious ulcer 3 years after a polyacr...

The combined use of a highly magnetic filler (mumetal) in low proportion and a highly conductive filler in high proportion in a polymer matrix provides a composite material that is more effective for electromagnetic interference shielding than the use of a highly magnetic filler alone or the use of a highly conductive filler alone. Mumetal is effective (due to absorption) when it is in a compos...

In this paper, I argue that the retrieval of filler-phrases in syntactic filler-gap dependencies is facilitated by encoding more information in the filler-phrase. Three self-paced reading experiments provide the evidence for this memory facilitation hypothesis: reading times decrease when more explicit whphrases and indefinites occur as fillers in three different syntactic constructions. Crucia...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Effect of TiO2 and ZrO2 filler on mechanical properties of the epoxy polymer has been investigated experimentally. TiO2 and ZrO2 filler epoxy composites are fabricated by hand layup technique in a mold and cured under light pressure at room tempera...

Filled pauses are ubiquitous in everyday speech. I investigated whether linguistic complexity of upcoming phrases affects filler rate at phrase boundaries in presentation speeches in Japanese. Filler rate at phrase boundaries increased monotonically with complexity of the following phrases. However, when the following phrase was composed of more than 11 Bunsetsu-phrases, the filler rate did not...
