The aim of this paper is to investigate the influence of physical and chemical factors on transport and use of substrate for Atta sexdens rubropilosa workers. Three types of rectangular fragments were used to study the physical influence factors： filter paper with paraffin, filter paper without paraffin and polyester film. To study the chemical factors, some fragments were impregnated with organic extract of orange albedo, others were soaked with soybean oil and for the remaining ones nothing was applied. The fonowing parameters were evaluated：（i） attractiveness of substrate for transport and number of loading workers per treatment; （ii） foraged material incorporation; （iii） rejection by numbers of fragments deposited in the garbage or beside the fungus garden. All the polyester film fragments carried out to the fungus garden were subsequently rejected. We verified that chemical factors of the substrate were more quickly detected by the workers, whereas physical factors were used as a criterion in the decision-making to reject or accept the substrate collected.

Proton exchange membrane(PEM)water electrolysis represents a promising technology for green hydrogen production,but its widespread deployment is greatly hindered by the indispensable usage of platinum group metal catalysts,especially iridium(Ir)based materials for the energy-demanding oxygen evolution reaction(OER).Herein,we report a new sequential precipitation approach to the synthesis of mixed Ir-nickel(Ni)oxy-hydroxide supported on antimony-doped tin oxide(ATO)nanoparticles(IrNiyO_(x)/ATO,20 wt.%(Ir+Ni),y=0,1,2,and 3),aiming to reduce the utilisation of scarce and precious Ir while maintaining its good acidic OER *** tested in strongly acidic electrolyte(0.1 M HclO_(4)),the optimised IrNi1Ox/ATO shows a mass activity of 1.0 mAµgIr^(−1) and a large turnover frequency of 123 s^(−1) at an overpotential of 350 mV,as well as a comparatively small Tafel slope of 50 mV dec^(−1),better than the IrOx/ATO control,particularly with a markedly reduced Ir loading of only 19.7µgIr cm^(−2).Importantly,IrNi1O_(x)/ATO also exhibits substantially better catalytic stability than other reference catalysts,able to continuously catalyse acidic OER at 10 mA cm^(−2) for 15 h without obvious *** in-situ synchrotron-based x-ray absorption spectroscopy confirmed that the Ir^(3+)/Ir^(4+)species are the active sites for the acidic ***,the performance of IrNi1Ox/ATO was also preliminarily evaluated in a membrane electrode assembly,which shows better activity and stability than other reference *** IrNi1Ox/ATO reported in this work is a promising alternative to commercial IrO_(2) based catalysts for PEM electrolysis.

盘状星系中的棒结构特征与星系自身所处环境及整体恒星形成特征之间存在复杂的相互关系。利用细致的星系形态特征测量计划Galaxy Zoo DECaLs中的数据构建了一组目前最大的具有同样恒星质量分布的强棒、弱棒和无棒星系样本。通过引入星系所处暗晕质量及相空间特征来控制星系所处的环境效应之后,进一步对比研究强棒、弱棒和无棒星系的恒星形成特征。研究表明,有棒星系中的恒星形成熄灭的比例系统地高于无棒星系,且强棒的效应更为明显。但是,对于仍处于恒星形成主序上的星系来说,强棒、弱棒和无棒星系的恒星形成特征并没有显著差别。以上结果表明,星系中的棒特征在其存在的时标中可能使部分星系迅速地从恒星形成转入熄灭状态。

Chinese women are speaking up about pain and shame on the gynecologist’s table In December, 23-year-old Wu Jiayi emerged,shaking, from the hospital. Though her gynecological appointment had only lasted 15 minutes, Wu, who agreed to be interviewed under a pseudonym, had spent almost an hour in the hospital bathroom, bleeding into the toilet after an invasive exam.

supercapacitors(sCs) are energy storage devices with the ability to charge and discharge at very high rates. The fast accumulation and release of charges occurs either electrostatically or electrochemically. There are two types of capacitors: electric double layer capacitors(EDLCs) and pseudocapacitors. EDLCs are the most commercially available.
