Abstract Novel Ni-PSF@PAO40 microcapsules (NPPMS) with high stability were prepared by using a combined processing method of electroless nickel plating and solvent volatilization. The results indicate that Ni is completely assembled on the surfaces PSF/PAO40 encapsulation capacity NPPMS achieved at 50%. Organic solvents immersion shows have an excellent chemical stability. Macro thermal tests r...

In the present study, novel natural fiber composites, consisting of untreated and alkali(NaOH)-treated chopped henequen fibers polyamide 6 (PA6), were produced by hopper feeding side fiber, upon extrusion process, then an injection molding respectively. The effects alkali treatment route on heat deflection temperature, tensile, flexural, Izod impact properties fiber/PA6 composites investigated....

Abstract Polyamide 6 (PA6) was modified with ethylene maleic anhydride syndiotactic copolymer resin (ZeMac), and triglycidyl isocyanurate (TGIC) as modifiers to prepare a grafting structure long-chain branching structure, respectively. The effects of two on the rheological behavior, crystallization properties, foaming performance, mechanical properties PA6 were systematically studied by rotatin...

Human embryonic stem cells (hESCs) are a promising source for cell replacement therapies. Parkinson's disease is one of the candidate diseases for the cell replacement therapy since the motor manifestations of the disease are associated with the loss of dopaminergic neurons in the substantia nigra pars compacta. Stromal cell-derived inducing activity (SDIA) is the most commonly used method for ...

The role of IL-7 in the stromal cell-dependent B cell development was investigated using two stromal cell clones, ST2 and PA6; the former supports B lymphopoiesis while the latter can not. We demonstrate here that: (a) the ability of the stromal cell clone to produce IL-7 correlates well with the stromal cell activity to support B lymphopoiesis; (b) IL-7 production by ST2 is inducible rather th...

Solid-state NMR was used to establish the specific intermolecular interactions responsible for the miscibility of blends of nylon 6 (PA6) and the zinc salt of lightly sulfonated polystyrene (Zn-SPS) and to characterize the scale of molecular mixing. l 3 C CPIMAS spectroscopy identified the interpolymer interaction as a complex between the Zn2+ cation of the ionomer and the amide nitrogen. Measu...

Oxyimides have gained wide interest in different applications because of radical generating properties, such as flame retardants various polymers. As polyamide-6 (PA6) is highly flammable and shows burning dripping during incineration the mentioned issues to be overcome by use a retardant. All previously developed oxyimides already show these but this based on ester structure with consequence t...

Due to material design and fabrication flexibility, additive manufacturing (AM) or 3D printing (3DP) processes polymer composites have paved their way into several industrial sectors. The quality of printed is highly dependent on the reinforcement content polymers 3DP process parameters. Several experimental studies are performed optimize contents parameters; however, exploring numerical modeli...
