豆荚状铬铁矿铂族元素地球化学研究进展

豆荚状铬铁矿是蛇绿岩中特有的一类矿产，按其化学成分可分为高Cr型和高Al型两种。其中的PGE主要以RuS2和Os、Ir、Ru合金等包体形式存在，或以类质同像形式进入铬铁矿晶格。两种类型的铬铁矿均表现出负倾斜型PGE配分模式，其Pt、Pd含量相近；与高Al型铬铁矿相比，高Cr型铬铁矿有更高的Os、Ir、Ru含量，部分豆荚状铬铁矿表现出Pt、Pd相对富集的平坦到正倾斜型PGE配分模式。目前对豆荚状铬铁矿PGE含量及配分模式还缺少一个统一的解释，但其PGE地球化学可为豆荚状铬铁矿的成因及构造背景解释提供更多的信息.

滇东南白牛厂银多金属矿床成矿元素特征

成矿物质来源是研究矿床成因的关键问题之一,而地质体（地层和岩浆岩）成矿元素的含量高低是探讨成矿物质来源的基础.为了研究白牛厂超大型银多金属矿床主要成矿元素特征,本文系统测定了外围赋矿地层以及矿区花岗岩和花岗斑岩的成矿元素（Ag、Pb、Zn、Sn）含量,结果表明,Pb、Zn主要来源于矿区花岗岩,寒武系及下伏基底地层可能也提供了部分成矿物质,特别是Zn;由于矿区外围赋矿地层的Sn含量远低于Pb、Zn的含量,也远远低于地壳克拉克值,因此推测,Sn主要来源于花岗岩浆;Ag则主要来源于赋矿地层,花岗岩对其进行了后期的改造作用.

感激与利他：从特质与情境的角度考察感激对利他倾向和行为的影响

Recently, as a moral affect and trait, gratitude has been acquiring growing attention in social psychology. Previous research showed those who are grateful were motivated not only to reciprocate the benefactor, but also to make altruistic behavior towards other people. By reviewing previous studies, we found two approaches on exploring the gratitude-altruism link: one is to examine the relationship of correlation between gratitude being a personality trait and altruistic tendency using questionnaires as research method; another is to probe into the causality of gratitude and altruistic behaviors by experimental methods. The present research consists of five studies combining correlative studies and experimental designs, trying to explore the effect of gratitude on altruistic tendency and altruistic behavior from perspective of trait and situation. Participants are 1769 Chinese undergraduates and 332 community residents. Firstly, results of study one showed dispositional gratitude was significantly positively correlated with altruistic tendency: higher dispositional gratitude, higher altruistic tendency. When social desirability, Big Five, and grateful mood were controlled, the correlation of gratitude and altruism still remained relatively significant. Secondly, results of the most experiments showed: main effects of both dispositional gratitude and situational gratitude were significant. For example, people with high dispositional gratitude showed higher altruistic tendency than people with low dispositional gratitude; People in high condition of gratitude arousing showed higher altruistic tendency than people in low condition of gratitude arousing as well as the control group. Thirdly, data analyses showed that the interaction effect of dispositional gratitude and situational gratitude on general altruistic tendency and altruistic behavior was significant. Compared with people with high dispositional gratitude, those with low dispositional gratitude was relatively more sensitive to condition of gratitude arousing. The latter show enhanced altruistic tendency in condition of gratitude arousing than in control condition. This interaction effect was also represented in three different condition of altruistic behavior. (1) As for beneficiaries of altruistic behavior, people with low dispositional gratitude showed enhanced altruistic behavior in condition of gratitude arousing towards strangers rather than friends and relatives. (2) As for the receiver role of altruistic behavior, people with low dispositional gratitude showed less “reject” or more “acceptance” in condition of gratitude arousing than that of the control condition. (3) When it comes to the cost of altruistic behavior, people with low dispositional gratitude showed enhanced altruistic tendency in condition of gratitude arousing than that of the control condition. However, altruistic behaviors of high cost in real life were more affected by dispositional gratitude.

Centenarians and their hearts: a prospective registry with comprehensive geriatric assessment, electrocardiogram, echocardiography, and follow-up

Background Data on the cardiac characteristics of centenarians are scarce. Our aim was to describe electrocardiogram (ECG) and echocardiography in a cohort of centenarians and to correlate them with clinical data. Methods We used prospective multicenter registry of 118 centenarians (28 men) with a mean age of 101.5 ± 1.7 years. Electrocardiogram was performed in 103 subjects (87.3%) and echocardiography in 100 (84.7%). All subjects underwent a follow-up for at least 6 months. Results Centenarians with abnormal ECG were less frequently females (72% vs 93%), had higher rates of previous consumption of tobacco (14% vs 0) and alcohol (24% vs 12%), and scored lower in the perception of health status (6.8 ± 2.0 vs 8.3 ± 6.8). Centenarians with significant abnormalities in echocardiography were less frequently able to walk 6 m (33% vs 54%). Atrial fibrillation/flutter was found in 27 subjects (26%). Mean left ventricular (LV) ejection fraction was 60.0 ± 10.5%. Moderate or severe aortic valve stenosis was found in 16%, mitral valve regurgitation in 15%, and aortic valve regurgitation in 13%. Diastolic dysfunction was assessed in 79 subjects and was present in 55 (69.6%). Katz index and LV dilation were independently associated with the ability to walk 6 m. Age, Charlson and Katz indexes, and the presence of significant abnormalities in echocardiography were associated with mortality. Conclusions Centenarians have frequent ECG alterations and abnormalities in echocardiography. More than one fifth has atrial fibrillation, and most have diastolic dysfunction. Left ventricular dilation was associated with the ability to walk 6 m. Significant abnormalities in echocardiography were associated with mortality.

Precursor adsorption on copper surfaces as the first step during the deposition of copper: a density functional study with van der Waals correction

Copper dimethylamino-2-propoxide [Cu(dmap)2] is used as a precursor for low-temperature atomic layer deposition (ALD) of copper thin films. Chemisorption of the precursor is the necessary first step of ALD, but it is not known in this case whether there is selectivity for adsorption sites, defects, or islands on the substrate. Therefore, we study the adsorption of the Cu(dmap)2 molecule on the different sites on flat and rough Cu surfaces using PBE, PBE-D3, optB88-vdW, and vdW-DF2 methods. We found the relative order of adsorption energies for Cu(dmap)2 on Cu surfaces is Eads (PBE-D3) > Eads (optB88-vdW) > Eads (vdW-DF2) > Eads (PBE). The PBE and vdW-DF2 methods predict one chemisorption structure, while optB88-vdW predicts three chemisorption structures for Cu(dmap)2 adsorption among four possible adsorption configurations, whereas PBE-D3 predicts a chemisorbed structure for all the adsorption sites on Cu(111). All the methods with and without van der Waals corrections yield a chemisorbed molecule on the Cu(332) step and Cu(643) kink because of less steric hindrance on the vicinal surfaces. Strong distortion of the molecule and significant elongation of Cu–N bonds are predicted in the chemisorbed structures, indicating that the ligand–Cu bonds break during the ALD of Cu from Cu(dmap)2. The molecule loses its initial square-planar structure and gains linear O–Cu–O bonding as these atoms attach to the surface. As a result, the ligands become unstable and the precursor becomes more reactive to the coreagent. Charge redistribution mainly occurs between the adsorbate O–Cu–O bond and the surface. Bader charge analysis shows that electrons are donated from the surface to the molecule in the chemisorbed structures, so that the Cu center in the molecule is partially reduced.
