Encapsulating metal organic framework into hollow mesoporous carbon sphere as efficient oxygen bifunctional electrocatalyst     

Wanfeng Xiong  Hongfang Li  Hanhui You  Minna Cao  Rong Cao 《国家科学评论(英文版)》2020,7(3):609

Applying metal organic frameworks (MOFs) in electrochemical systems is a currently emerging field owing to the rich metal nodes and highly specific surface area of MOFs. However, the problems for MOFs that need to be solved urgently are poor electrical conductivity and low ion transport. Here we present a facile in situ growth method for the rational synthesis of MOFs@hollow mesoporous carbon spheres (HMCS) yolk–shell-structured hybrid material for the first time. The size of the encapsulated Zeolitic Imidazolate Framework-67 (ZIF-67) is well controlled to 100 nm due to the spatial confinement effect of HMCS, and the electrical conductivity of ZIF-67 is also increased significantly. The ZIF@HMCS-25% hybrid material obtained exhibits a highly efficient oxygen reduction reaction activity with 0.823 V (vs. reversible hydrogen electrode) half-wave potential and an even higher kinetic current density (J_K = 13.8 mA cm⁻²) than commercial Pt/C. ZIF@HMCS-25% also displays excellent oxygen evolution reaction performance and the overpotential of ZIF@HMCS-25% at 10 mA cm⁻² is 407 mV. In addition, ZIF@HMCS-25% is further employed as an air electrode for a rechargeable Zn–air battery, exhibiting a high power density (120.2 mW cm⁻² at 171.4 mA cm⁻²) and long-term charge/discharge stability (80 h at 5 mA cm⁻²). This MOFs@HMCS yolk–shell design provides a versatile method for the application of MOFs as electrocatalysts directly.  相似文献   

Rapid phenotypic evolution with shallow genomic differentiation during early stages of high elevation adaptation in Eurasian Tree Sparrows

Known as the ‘third polar region’, the Qinghai-Tibet Plateau represents one of the harshest highland environments in the world and yet a number of organisms thrive there. Previous studies of birds, animals and humans have focused on well-differentiated populations in later stages of phenotypic divergence. The adaptive processes during the initial phase of highland adaptation remain poorly understood. We studied a human commensal, the Eurasian Tree Sparrow, which has followed human agriculture to the Qinghai-Tibet Plateau. Despite strong phenotypic differentiation at multiple levels, in particular in muscle-related phenotypes, highland and lowland populations show shallow genomic divergence and the colonization event occurred within the past few thousand years. In a one-month acclimation experiment investigating phenotypic plasticity, we exposed adult lowland tree sparrows to a hypoxic environment and did not observe muscle changes. Through population genetic analyses, we identified a signature of polygenic adaptation, whereby shifts in allele frequencies are spread across multiple loci, many of which are associated with muscle-related processes. Our results reveal a case of positive selection in which polygenic adaptation appears to drive rapid phenotypic evolution, shedding light on early stages of adaptive evolution to a novel environment.  相似文献   

我国高技术产业的区域分布失衡问题分析   总被引：1，自引：0，他引：1  

熊英  汤亚非  邹纲明 《现代情报》2010,30(8):157-162

通过对我国高技术产业的绩效数据的分析,其中包括:总产值、主营收入、增加值、新产品产值、利税和出口交货值等多个方面的数据,了解到我国高技术产业在全国区域分布,发现高技术产业集中我国的东部地区,而中部和西部在高技术领域处于明显劣势,严重影响我国高技术产业的均衡发展。据此建议国家应该尽快调整高技术的产业结构,让高技术产业成果,带给中部和西部的人民一些经济实惠。  相似文献   

Cultural Connections and Disconnections Between Non-Hmong Principals and Hmong Parents     

Tong T. Xiong  Festus E. Obiakor 《Multicultural Perspectives》2013,15(1):39-45

The purpose of the authors in this qualitative research is to explore cultural connections and disconnections between non-Hmong principals and Hmong parents. The results show that cultural disconnections occur because of the lack of culturally sensitive professional development for teachers and principals, and the lack of understanding of Hmong cultural values and beliefs, especially when it comes to parental involvement.  相似文献
