During the electroplating, the mechanical attrition(MA) was introduced by impact of glass balls on the sample surface with a special vibrating frequency. The surface and cross-sectional images of Ni coating were observed with SEM. The microstructure and crystallinity of coating were examined with TEM and XRD. The electrochemical performance of coating was measured with polarization curves and electrochemical impedance spectroscopy (EIS) and its mechanical behaviours, such as tensile strength and hardness, were studied. The results show that the MA has significant effects on the microstructure and property of the electroplated Ni coating. By MA, the coating becomes smooth, compact, thin and has refined grains and is free of cracks and pores. Consequently, the adhesion, tensile strength, hardness and corrosion resistance of coating are improved significantly.展开更多

Ion conductive polymer film (ICPF) actuators have been one of the strong candidates. The ICPF investigated here was a cation-exchange membrane (Nation 117, Du Pont). When a voltage is given between the metal eIectrodes of an ICPF actuator, the ICPF actuator bends in the water due to the motion of Li+ cations with associated water. In order to increase the freedom of the deformation of the ICPF actuator, structures of independent electrode pairs were proposed. The electrodes were selectively deposited by non-electrokvzed plating including the Pt [(NH3)6]^4+ deposition process in a [Pt(NH3)6]Cl4 solution and the reduction process in a NaBH4 solution.

METHODS: Totally 74 patients with acute ischemic stroke were enrolled and divided into either body acupuncture (Control) or electro-scalp acupuncture (ESA) groups according to randomized controlled principle. The patients in the control group were given body acupuncture treatment once daily for 28 d, whereas except for the body acupuncture, electro-scalp acupuncture was additional treatment given to the ESA group. Neurological deficits, everyday motor function and muscle strength were evaluated at baseline and the 28th d by NIH Stroke Scale (NIHSS), FugI-Meyer Assessment (FMA) and Modified Barthel Index Score (MBI), respectively. RESULTS: There were not obvious between-group differences in the baseline efficacy parameters (NI- HSS, FMA and MBI) (all P 〉 0.05), whereas signifi- cant between-group differences were found in post-treatment NIHSS, FMA-UE and MBI scores (all P 〈 0.05). After acupuncture treatment, systematic within-group improvements were found in the two groups for any of the efficacy parameters assessed (all P 〈 0.01), and the ESA group showed higher significant improvements in NIHSS, FMA-UE and MBI scores (all P 〈 0.05). CONCLUSION: Electro-scalp acupuncture was efficacious in the treatment of acute ischemic stroke, which resulted in meaningful improvements in neurologic function, motor function and activities of daily living of patients.展开更多
