No full textAMIOTA GUIENSIS XU & CHEN SP. NOV. (FIG. 2) Specimens examined: Holotype male (SCAU 121736) and six male paratypes (SCAU 121737–121742), China, Fushui, Chongzuo, Guangxi, 230 m a.s.l., 23 August 2004, H.W. Chen. Etymology: Pertaining to shortened form Guangxi of the type locality. Diagnosis: This species is slightly similar to A. lambirensis in the shape of the distal part of the paramere, but can be distinguished by the following characters: in lambirensis the distal part of the paramere is distinctly longer than the basal part in ventral view, and is basally triangularly expanded in lateral view (Chen et al., 2007: figs. 18, 19). Description: Male. Thorax nearly entirely brown. Abdominal tergites dark brown, except for first to third yellow medially. Male terminalia: epandrium pubescent except for ventral margin, with ~11 setae near posterior margin on each side of the body (Fig. 2A). Surstylus with several setae and roughly eight prensisetae (Fig. 2B). Paramere distally with about five sensilla and slightly curved, submedially with about six sensilla arranged in a small patch, apparent in lateral view (Fig. 2D). Vertical lobe of gonopod broad, arched, slightly sclerotized (Fig. 2C, D). Aedeagal apodeme longer than wide (Fig. 2D). Female: unknown.Published as part of Zhao, Feng, Xu, Xiaoyang, Jiang, Jianjun, He, Xiaofang & Chen, Hongwei, 2013, Molecular phylogenetic analysis of the Amiota apodemata and Amiota sinuata species groups (Diptera: Drosophilidae), with descriptions of four new species, pp. 849-858 in Zoological Journal of the Linnean Society 168 (4) on page 853, DOI: 10.1111/zoj.12043, http://zenodo.org/record/528587
Effect of electrolytes on electrochemical properties of MmNi(5)-based hydrogen storage alloy
No full textThis Project is financially supported by the National Natural Foundations of China (51261003), the Natural Foundations of Guangxi Province (2012GXNSFGA060002; 2011GXNSFD018004; 201201ZD009) Guangxi Experiment center of information science (20130113) and National students’ Innovative Project (101059530) and National students’ Innovative Project (101059530).The effect of electrolytes on the electrochemical properties of MmNi(3.68)Co(0.72)Mn(0.43)Al(0.17) hydrogen storage alloy electrodes has been investigated at 303 K and 273 K. Three electrolytes (EL1, EL2, EL3) were obtained by adding 2 wt%, 4 wt% and 6 wt% LiOH into the original electrolyte EO (6 M/ L KOH), respectively. The results indicate that the addition of LiOH improves the discharge capacity and cycle life at 303 K and 273 K. The highest maximum capacity and capacity retention (after 50th cycles) have been observed in electrolyte EL2. However, the high-rate dischargeability (HRD) decreases gradually from EO to EL3 at the two temperatures because of the addition of LiOH. The corrosion current I-corr from Tafel Polarization curves (TP) and the resistance of the oxide layer R-ol from electrochemical impedance spectroscopy (EIS) indicates that the alloy electrode worked in EL1 has a better anti-corrosion ability. The real surface area of the electrodes estimated with EIS analysis, decrease from 51.95 cm(2) in EO to 15.6 cm(2) in EL2, but increase to 31.59 cm(2) in EL3 after being fully activated. The additional LiOH improves the anti-pulverization ability of alloy powders, delay the loss of active elements within the alloy electrode, resulting in an inproved capacity retention of alloy electrode. Meanwhile, the electrochemical kinetics analysis suggests that the charge-transfer reaction at the interface of electrode surface and electrolyte is the rate-determining step when tested at 303 K and 273 K.Peer reviewe
