Despite the great potential of graphene as a nanofiller, achieving homogeneous dispersion remains the key challenge for effectively reinforcing polyolefin (such as polyethylene (PE) and polypropylene (PP)) nanocomposites. Therefore, in this research, we report a facile combined in situ polymerization and masterbatch method for fabricating PP/reduced graphene oxide (rGO) nanocomposites. In the p...

A fourth-generation Ziegler-Natta catalyst was prepared to synthesize polypropylene (PP), which was stabilized by in situpolymerization employing lignin as antioxidant. The antioxidant properties of lignin were compared with those of the commercial antioxidant Irganox 1010. The presence of lignin in the reaction medium slightly decreased the catalytic activity of the reaction. The isotacticity ...

What was Leibniz’s take on the fundamental theorem of calculus? He was one of the creators of the field after all, so one is naturally curious. But if you go to the library to find the answer to this question youwill be sold a baitand-switch. You will be referred to his 1693 article [15], supposedly the only place where Leibniz explicitly stated and proved the fundamental theorem of calculus in...

Background: Literature review shows that there are not sufficient data about polyphenolic compounds of peel of Iranian pomegranate. So, this work was mainlyundertaken to determine phenolic compounds and antioxidant activity of dried peel of Iranian pomegranate. Methods: Pomegranate fruits were obtained from mature fruits grown in Saveh, Iran and the Pomegranate Peel (PP) were dried with three ...

Graphene nanoplatelets (GNP) are used to produce wood plastic composites (WPC) with improved electrical and thermal conductivity. The polypropylene/wood/GNP hybrid produced by melt compounding followed hot pressing. effect of GNP loadings (5, 10 15 wt%) on conductivity, tensile properties, degradation WPC containing 20 wt% flour is studied. fast slow cooling rates during pressing the surface re...
