Chemical Cross Linking

The core–shell structure composite magnetic nanoparticles (NPs), Fe3O4@chitosan@nimodipine (Fe3O4@CS@NMDP), were successfully synthesized by a chemical cross-linking method in this paper. NMDP is widely used for cardiovascular and cerebrovascular disease prevention and treatment, while CS is of biocompatibility. The composite particles were characterized by an X-ray diffractometer (XRD), a Fourier transform infrared spectroscopy (FT-IR), a transmission electron microscopy (TEM), a vibrating sample magnetometers (VSM) and a high performance liquid chromatography (HPLC). The results show that the size of the core–shell structure composite particles is ranging from 12[Formula: see text]nm to 20[Formula: see text]nm and the coating thickness of NMDP is about 2[Formula: see text]nm. The saturation magnetization of core–shell composite NPs is 46.7[Formula: see text]emu/g, which indicates a good potential application for treating cancer by magnetic target delivery. The release percentage of the NMDP can reach 57.6% in a short time of 20[Formula: see text]min in the PBS, and to 100% in a time of 60[Formula: see text]min, which indicates the availability of Fe3O4@CS@NMDP composite NPs for targeting delivery treatment.

Coumarin-based, photo-cross-linkable core–shell bottlebrush copolymers were synthesized by a grafting-from approach. Hollow cylindrical nanocapsules were generated by selective, metal-free shell photo-cross-linking followed by hydrolytic core removal.

Counterface Roughness

In this investigation, the sliding wear of polyetheretherketone (PEEK) against smooth (polished) and slightly roughened mild-steel counterfaces was studied under dry, lightly-loaded conditions. In this counterface roughness regime, the wear rate of PEEK decreased to a relative minimum as roughness increased. The worn system of PEEK against polished steel was simulated using several contact models. The application of a numerical non-Hertzian elastic stress analysis yielded estimates of subsurface stresses, which were correlated with results of wear particle morphological studies. As counterface roughness increased, minor changes were observed in the wear mechanism. Wear particle morphology, however, displayed evidence of mechanical counterface interaction resulting in interfacial film formation and reduced wear.
