Completely discontinuous organic/ inorganic hybrid nanocomposites by self-curing of nanobuilding blocks constructed from reactions of [HMe 2 SiOSiO 1.5 ] 8 with vinylcyclohexene
(John Wiley & Sons, Ltd., 2007-11)
The reaction of 4-vinyl-1-cylcohexene with [HMe 2 SiOSiO 1.5 ] 8 provides tetra- and octa-2-cyclohexenylethyloctasilsesquioxanes. The tetrabifunctional [cyclohexenylethylMe 2 SiOSiO 1.5 ] 4 -[HMe 2 SiOSiO 1.5 ] 4 (average ...
Positronium formation in semicrystalline poly(ethylene terephthalate)
(Elsevier, 1994-01)
The probability of positronium (Ps) formation in semicrystalline poly(ethylene terephthalate) (PET), has been investigated by means of positron annihilation lifetime spectroscopy (p.a.l.s.). The p.a.l.s. data are correlated ...

Aufgerollt wie ein Teppich : Durch Anbringen flexibler KnÄuel an den Mittelteil starrer stabfÖrmiger MolekÜle entstehen T-fÖrmige Stab-KnÄuel-Konstrukte, die selbstorganisierte Schichten aufbauen. Diese Schichten rollen ...
Cure versus Flow in Dispersed Chip-Underfill Materials
(WILEY-VCH Verlag, 2008-10-10)
The relative stability of chip-underfill composite materials was modeled as a function of glass filler concentration between 10 and 70 wt.-%, filler particle size (between 5 and 25 microns), and the curing temperature of ...
Mechanical properties of in situ composites based on polycarbonate and a liquid crystalline polymer
(Elsevier, 1994-08)
The mechanical properties of in situ composites based on blends of polycarbonate and a liquid crystalline copoly(ester amide) (Vectra B950) have been studied as functions of the liquid crystalline polymer (LCP) concentration ...
Toughening mechanisms in core-shell rubber modified polycarbonate
(Elsevier, 1990-12)
We have conducted a study of toughening mechanisms in rubber modified polycarbonate systems in order to evaluate the sequence of deformation events which improve fracture toughness. We conclude that cavitation of the rubber ...
Highly Efficient, Near-Infrared Electrophosphorescence from a Pt–Metalloporphyrin Complex The authors acknowledge financial support from the U.S. Dept. of the Army, CECOM for the phase 14II SBIR program (contract no. 14W15P7T-06-C-T201), and Universal Display Corporation.

Deformation behaviour of a polycarbonate plate with a circular hole: finite elements model and experimental observations
(Elsevier, 1988-09)
The unique and complex deformation behaviour of ductile polymers has received considerable attention in the polymer field. Much research has been conducted to study the yielding and post-yielding behaviour of polymers. In ...
