A simple formulation of a stable high internal phase emulsion of dicyclopentadiene which is cured by using properly selected ring opening metathesis polymerization initiators yields highly porous monolithic materials with paramount mechanical properties and the possibility of easy functionalisation.

نانوالیاف کامپوزیتی پلی­کاپرولاکتون(PCL)/ دی­ کلسیم ­فسفات دی ­هیدرات(DCPD)  در حلال مناسب کلروفرم/متانول(۲۵:۷۵) با روش الکتروریسی تهیه شدند. نتایج حاصل از میکروسکوپ الکترونی روبشی نشان دهنده یکنواختی مناسب الیاف و عدم نقص گره با تغییر پارامتر الکتروریسی می­باشد. همچنین نتایج نقشه برداری عنصری حضور و توزیع مناسب نانوذرات DCPD در ماتریس  PCLتایید می­کند. نتایج حاصل از اندازه­گیری زاویه تماس نشان...

A structurally well-defined THF-free cationic half-sandwich scandium aminobenzyl complex serves as a novel catalyst for the first copolymerization of 1-hexene with dicyclopentadiene to give the random copolymers with a wide range of 1-hexene contents (32-70 mol%) unavailable previously.

Hepatitis B virus (HBV) is the prototype of hepatotropic DNA viruses (hepadnaviruses) infecting a wide range of human and non-human hosts. Previous studies with duck hepatitis B virus (DHBV) identified duck carboxypeptidase D (dCPD) as a host specific binding partner for full-length large envelope protein, and p120 as a binding partner for several truncated versions of the large envelope protei...

The hydroxyapatite (HAP) with variable chemical substitutions has been considered as the major component in the mineralized part of bones. Various metastable crystalline phases have been suggested as transitory precursors of HAP in bone, but there are no consensuses as to the nature of these phases and their temporal evolution. In the present study, we cultured rat calvarial osteoblasts with as...

A generalized silica coating scheme is used to functionalize and protect sub-micron and micron size dicyclopentadiene monomer-filled capsules and polymer-protected Grubbs' catalyst particles. These capsules and particles are used for self-healing of microscale damage in an epoxy-based polymer. The silica layer both protects the capsules and particles, and limits their aggregation when added to ...

Kinetic studies of the transformation calcium orthophosphates metastable precipitates are performed under different synthesis conditions. The phase composition and degree crystallinity investigated by X-ray powder diffraction analysis. In acidic solution, CaHPO 4 . 2H 2 O (DCPD) (DCPA) formed at early stage precipitation, with range 17–35%. Specifically, DCPD 30 °C anhydrous DCPA 50 °C. alkalin...
