-deposited method, and the effects of the saccharin content in the electrolytes on the microstructure of the coatings were studied by using X-ray diffractometry(XRD), scanning electron microscopy(SEM) and transmission electron microscopy(TEM). The results show that the saccharin content in the bath affects the plating rates and the current efficiency remarkably. As the saccharin content increases......

Quasi-static and dynamic tensile behaviors in electron beam welded Ti-6Al-4V alloy ZHANG Jing1, TAN Cheng-wen1, 2, REN Yu1, WANG Fu-chi1, CAI Hong-nian1 1. School of Materials Science..., Beijing 100081, China Received 11 December 2009; accepted 23 March 2010 Abstract: The quasi-static and dynamic tensile behaviors in electron beam welded (EBW) Ti-6Al-4V alloy were investigated......
structure of the nanocrystals was confirmed by powder X-ray diffraction (XRD) and electron diffraction (ED) studies. The size of the crystals was observed using transmission electron microscope (TEM). The oxidation state of Mn in ZnSe nanocrystal was found using electron spin resonance (ESR) spectrum. The room temperature luminescence measurements show the peaks corresponding to both bandgap......
. Overall, these data suggest a very complex picture of aerobic respiration by S. oneidensis MR-1. Key words: cytochrome; mutant; electron transport; pellicle; biofilms ... contaminants in the environment. S. oneidensis MR-1 has been extensively studied, including the development of the canonical biofilms [3-9]. S. oneidensis MR-1 possesses a complex electron- transport system......
, such as low reduction potential as cathode materials or high reduction potential as anode materials. Here, the influence of chemical functionalities that are capable of either electron donating or electron withdrawing groups on the reduction potential and charge-discharge performance of anthraquinone (AQ) based system is studied. The cyclic voltammetry results show that the introduction of two -OH......
