Catalyst–support interaction plays a crucial role in improving the catalytic activity of oxygen evolution reaction(OER).Here we modulate the catalyst–support interaction in polyaniline-supported Ni_(3)Fe oxide(Ni_(3)Fe oxide/PANI)with a robust hetero-interface,which significantly improves oxygen evolution activities with an overpotential of 270 mV at 10 mA cm^(-2)and specific activity of 2.08 mA cm_(ECSA)^(-2)at overpotential of 300 mV,3.84-fold that of Ni_(3)Fe *** is revealed that the catalyst–support interaction between Ni_(3)Fe oxide and PANI support enhances the Ni–O covalency via the interfacial Ni–N bond,thus promoting the charge and mass transfer on Ni_(3)Fe *** the excellent activity and stability,rechargeable Zn-air batteries with optimum Ni_(3)Fe oxide/PANI are assembled,delivering a low charge voltage of 1.95 V to cycle for 400 h at 10 mA cm^(-2).The regulation of the effect of catalyst–support interaction on catalytic activity provides new possibilities for the future design of highly efficient OER catalysts.

为了探明固化期间缓黏结预应力混凝土梁的力学性能,制作了4根缓黏结预应力混凝土梁,每根梁直线布置3根缓黏结预应力钢筋,进行试验梁的抗弯承载力测试。通过邵氏硬度计测得试验梁缓黏结剂的硬度,用以反映缓凝材料在加载试验时的固化性质;然后把试验梁分4批进行三分点两点同步单调静力加载试验;最后通过监测梁挠度、关键截面混凝土的应变变化、预应力钢筋张拉端和锚固端的压力变化、裂缝分布等指标,明确缓黏结预应力钢筋与混凝土之间的传力机理以及混凝土梁的抗弯承载能力。结果表明:缓黏结剂的固化度对预应力混凝土梁的开裂荷载影响较小,对最大承载力影响较大,利用现有的预应力混凝土计算理论计算得到的开裂荷载与试验结果吻合较好,但最大承载力的理论计算结果相对保守;随着缓黏结剂逐渐固化,预应力混凝土梁的极限承载力随之增加,当缓黏结剂的邵氏硬度(D型)达到80时,缓黏结预应力钢筋与混凝土具有良好的共同工作状态,梁纯弯段部分的裂缝开展均匀,数量较多,其承载力及延性也最大。

东营凹陷民丰北带地区砂砾岩体发育广泛,其岩电关系不明显;加之常规层序地层研究方法具有主观人为因素过多的弊端,制约了该地区层序地层研究工作的深化。基于测井资料的小波变换技术与基于地震资料的时频分析技术,与常规方法相比,具有定量划分层序地层的优势。在常规层序研究方法的基础上,综合利用以上两种技术,准确定量地划分了东营凹陷民丰北带地区沙四上亚段的四级层序。研究表明:基于测井资料的小波变换技术和基于地震资料的时频分析技术本质上具有一致性,都是在频率域定量划分层序地层;小波变换技术分辨率高,适用于有井区,地震时频分析技术适用性广,但分辨率低,两者需结合使用。东营凹陷民丰北带地区沙四上亚段地层为一个完整的三级层序,进一步可细分为5个四级层序,每个四级层序都具有粒度向上变细的正旋回的沉积特点。
