A First-principles Calculation of Structures and Stability of Al_(13)I Cluster

Chinese Journal of Structural Chemistry 2006年第2期25卷 232-239页

作者： li gui-fa peng ping yang feng han shao-chang School of Materials Science ＆ Engineering Hunan University Changsha 410082 China

Using first-principles pseudo-potential plane wave method, the energetics, geometrical and electronic structures of three Al13I cluster isomers were calculated. The calculation results of the binding energy indicate Al13I cluster is more stable than Al13 cluster although its electrons are not a magic number as in Alia cluster, and among Al13I cluster isomers the ＂Bridge＂ structure is the most stable, the second is the ＂Ontop＂ structure, and the worst is the ＂Hollow＂ structure. By analyzing the geometrical structures of Al13I cluster isomers, it is found that after I atom and Al13 cluster combine the geometrical structures of Al13 moieties are changed besides Al13I Hollow cluster, in which the Alia moiety is still a regular icosahedron. For Al13I Ontop cluster, the Al13 moiety has a shrinking trend to I, whereas in Al13I Bridge cluster it is distorted. Mulliken population analysis shows for the interaction of electrons between Al-I atoms in Al13I cluster not only there exists an ionic bonding but there is a covalent bonding. Part of electrons in the Alia cluster transfer to I as Al13 cluster and I atom combine. The order of the strength of covalent bonding between Al13 moiety and I in Al13I cluster isomers is Al13IBridge〉Al13IHollow〉Al13I Ontop. Further analysis of electric structures of Al13 and Al13I clusters indicates a higher stability of Al13I cluster than Al13 cluster can be attributed to the s-p hybridization of 3s and 3p electrons of Al in Al13 moiety induced by 1 doped, which leads to fewer electrons N（EF） at EF in Al13I and a larger energy gap △EH-L between HOMO and LUMO levels in Al13I cluster. The distinguish of structural stability of Al13I cluster isomers mainly originates from their different magnitudes .in decrease of N（EF） and increase of △EH-L relative to Al13 cluster. The fewest N（EF） and the largest △EH-L are responsible for the high stability of Al13I Bridge cluster.

目的多维度评估农村居民的镉暴露水平,分析环境镉暴露与居民内暴露水平之间的关联性。方法在典型土壤镉污染区和土壤镉清洁区采集土壤和出产农作物样本,选择当地成年常住居民为调查对象,采集晨间空腹随机中段尿液样本,并开展膳食调查。采用电感耦合等离子体质谱法检测环境和生物样本镉含量。采用相关分析、通径分析、广义线性回归等统计学方法探究环境镉暴露与人体镉负荷的关联。结果污染区和清洁区的土壤镉、大米镉以及蔬菜镉含量的中位数分别为0.50 mg/kg vs.0.49 mg/kg、0.23 mg/kg vs.0.02 mg/kg和0.03 mg/kg vs.0.02 mg/kg;污染区调查对象日均膳食镉摄入和尿镉水平显著高于清洁区,两地区居民日均自产粮食镉摄入和尿镉水平的中位数分别为2.59μg/kg体重(body weight,BW)vs.0.19μg/kg BW和4.27μg/g肌酐vs.1.34μg/g肌酐。土壤镉、大米镉、蔬菜镉和自产粮食镉摄入均与尿镉显著正相关,相关系数分别为0.36、0.78、0.61和0.69(P值均<0.05)。通径分析结果显示,大米镉含量是影响尿镉水平的主要决定因子。广义线性回归分析的结果显示,日均自产粮食镉摄入量每增加1μg/kg BW,尿镉增加0.69μg/g肌酐;日均大米镉摄入量每增加1μg/kg BW,尿镉增加0.68μg/g肌酐。结论环境镉暴露与人体镉负荷水平存在正向暴露—反应关系,控制大米镉摄入是降低人群镉暴露的首要途径。

中子辐射俘获反应在反应堆运行、核装置设计及核天体物理研究中起重要的作用.4πBaF_(2)探测装置有着高时间分辨能力、低中子灵敏度、高探测效率等优点,适合开展中子辐射俘获反应截面数据的测量.中国原子能科学研究院核数据重点实验室建立了伽马全吸收装置(Gamma total absorption facility,GTAF),该装置用28块六棱BaF_(2)晶体和12块五棱BaF_(2)晶体构成了外径25 cm,内径10 cm的球壳,覆盖了95.2%的立体角.利用GTAF在中国散裂中子源Back-n束线上,测量了197Au(n,γ)的反应截面数据.测量数据通过能量筛选、PSD方法、晶体多重性筛选进行了初步本底扣除,随后结合对^(nat)C及空样品的测量数据对本底进行了分析及扣除,获得了197Au俘获反应的产额,利用SAMMY程序拟合得到了^(197)Au在1—100 e V的共振能量、中子共振宽度和伽马共振宽度参数.实验测量结果与ENDF/B-VIII.0数据库符合良好,其共振参数存在一定差异,分析原因可能与GTAF能量分辨率、Back-n的中子能谱测量精度、以及实验本底扣除方法相关,这也是下一步工作的重点.

Characteristics of SARS-CoV-2 transmission in a medium-sized city with traditional communities during the early COVID-19 epidemic in China

Virologica Sinica 2022年第2期37卷 187-197页

作者： yang li Hao-Rui Si Yan Zhu Nan Xie Bei li Xiang-ping Zhang Jun-feng han Hong-Hong Bao Yong yang Kai Zhao Zi-Yuan Hou Si-Jia Cheng Shuan-Hu Zhang Zheng-li Shi peng Zhou CAS Key Laboratory of Special Pathogens and Biosafety Wuhan Institute of VirologyChinese Academy of SciencesWuhan430071China Anyang Municipal Center for Disease Control and Prevention Anyang455000China University of Chinese Academy of Sciences Beijing101409China

The nationwide COVID-19 epidemic ended in 2020, a few months after its outbreak in Wuhan, China at the end of2019. Most COVID-19 cases occurred in Hubei Province, with a few local outbreaks in other provinces of China. A few studies have reported the early SARS-Co V-2 epidemics in several large cities or provinces of China. However,information regarding the early epidemics in small and medium-sized cities, where there are still traditionally large families and community culture is more strongly maintained and thus, transmission profiles may differ, is limited. In this study, we characterized 60 newly sequenced SARS-Co V-2 genomes from Anyang as a representative of small and medium-sized Chinese cities, compared them with more than 400 reference genomes from the early outbreak, and studied the SARS-Co V-2 transmission profiles. Genomic epidemiology revealed multiple SARS-Co V-2 introductions in Anyang and a large-scale expansion of the epidemic because of the large family ***, our study revealed two transmission patterns in a single outbreak, which were attributed to different social activities. We observed the complete dynamic process of single-nucleotide polymorphism development during community transmission and found that intrahost variant analysis was an effective approach to studying cluster infections. In summary, our study provided new SARS-Co V-2 transmission profiles representative of small and medium-sized Chinese cities as well as information on the evolution of SARS-Co V-2 strains during the early COVID-19 epidemic in China.
