This study aims to explore the relationship between college students' volunteer service experience, self-efficacy and moral identity Public Service Motivation(PSM). It provides empirical insights for improving PSM among students informs educational programs policies that can promote a more active service-oriented youth population. A questionnaire-based was conducted in Jiangxi Hunan provinces, using Volunteer Experience Scale, Self-Efficacy Moral Identity Motivation Scale. Data were...

Integrating natural macromolecules, e.g. proteins, is a progressive trend in the fabrication of biocompatible sub-micrometer fibers with tunable diameters using electrospinning technique. The correlation between solution properties and electrospun morphology critical; it quite clear for synthetic linear polymer solutions but remains uncertain protein. Here, we report determination protein-polymer poly(ethylene oxide) (PEO) zein, storage protein from corn. viscosity zein/PEO mixed can be well...

A clear description of the conformational and dynamical evolution polymer chains in shear flow is fundamental basis microfluidic separations macroscopic rheological behaviors. We employ graph theory analysis to analyze local deformation dynamics linear with different rigidities based on simulation trajectories that record instantaneous conformations dynamics. Our results show all semiflexible experience quasi-periodic tumbling motions when strain overwhelms U-shape (or S-shape) energy...
