Investigation on nonisothermal crystallization kinetics of the high-flow nylon 6 by differential scanning calorimetry
关键字：nonisothermal crystallization kinetics
The crystallization kinetics of the high-flow nylon 6 containing polyamidoamine (PAMAM) dendrimers units in nylon 6 matrix was investigated by differential scanning calorimetry. The Ozawa and Mo equations were used to describe the crystallization kinetics under non-isothermal condition. The values of Avrami exponent m and the cooling crystallization function F(T) were determined from the Ozawa plo...

Isothermal crystallization kinetics of high-flow nylon 6 by differential scanning calorimetry
关键字：isothermal crystallization kinetics; nylon 6; differential scanning calorimetry
The isothermal crystallization kinetics was investigated by differential scanning calorimetry for high-flow nylon 6, which was prepared with the mother salt of polyamidoamine (PAMAM) dendrimers and p-phthalic acid, end capping agent and ε-caprolactam by in situ polymerization. The Avrami equation has been adopted to study the crystallization kinetics. Comparing with pure nylon 6, the high-...

A Core-shell Nanostructure Ensures High Gene Transfection Efficacy and IVIinimal Cytotoxicity
关键字：core-shellnanostructure dendrimer polyethyleneimine gene delivery
Cationic dendrimers and polyethyleneimine (PEI) have been widely investigated both in vitro and in vivo. Generally, high generation dendrimer and high molecular weight PEI possess relatively high transfection efficacy, but they are associated with serious cytotoxicity during gene transfection. In comparison, low generation dendrimer and low molecular weight PEI has good
biocompatibility but poo...

A Visualization Method to Investigate the Mechanism of Cell Nucleation and Growth in High-Pressure Foam Injection Molding
Introduction
Foam injection molding (FIM) is one of the most promising technologies owing to its ability to
produce low-density parts with high geometrical accuracy and stiffness-to-weight ratio at fast
production cycles [i]. In this technology, a gas-charged melt is being injected into a confined cavity.In low-pressure FIM, i.e. short shot injection, foaming occurs due to the pressure drop ov...
