Barrel temperature control in injection molding process
In this paper, the barrel temperature control is selected to illustrate the recent R&D progress of CPPS. As polymer processing is mainly through extrusion and injection molding, they both utilize a screw-barrel system to melt ...

Morphology control and characterization of broom-like porous CeO2
In this study, CeO2 with a broom-like porous hierarchical structure was successfully prepared by a simple template-free hydrothermal method. In the whole hydrothermal process, reaction time and temperature play important roles in morphology control. The morphology of the as-prepared samples was characterized by field emission scanning electron microscopy, transmission electron microscopy and high-...

JOC--Absolute Control of Helical Handedness in Quinoline Oligoamides
The synthesis of quinoline-derived helically folded aromatic oligoamides functionalized by various chiral functions at their N-terminus is reported. When a (1S)-(?)-camphanyl moiety was introduced, it was found that helix handedness was completely shifted to right-handed helicity (de > 99%), in both protic and nonprotic solvents. The absolute helical sense and the de values were unambiguously...

Rational Synthesis of Heterostructured Nanoparticles with Morphology Control
Rational synthesis of Pt−Aun nanoparticles (NPs) has been achieved by overgrowing Au on Pt with n, the number of Pt−Au heterojunctions in each particle, controlled from 1 to 4, and the corresponding NPs in pear-, peanut-, or clover-like morphology. Monte Carlo simulation reveals that the morphology control can be correlated to a thermodynamic equilibrium of the Au coherence energy, the...

The morphology evolution and Size control of polypropylene nanofibers
关键字：morphology evolution， size control， PP nanofibers
Polyproplylene (PP) nanofibers were prepared by melt-blending extrusion of cellulose acetate butyrate (CAB) and PP and subsequent removal of the CAB matrix. The sizes and distributions of nanofibers were controlled by morphology development...
