Enhanced Hydrogen Evolution Catalysis of Pentlandite due to the Increases in Coordination Number and Sulfur Vacancy during Cubic-Hexagonal Phase Transition.

The search for new phases is an important direction in materials science. The phase transition of sulfides results in significant changes in catalytic performance, such as MoS and WS. Cubic pentlandite [cPn, (Fe, Ni)S] can be a functional material in batteries, solar cells, and catalytic fields.

Oldhamite: a new link in upper mantle for C-O-S-Ca cycles and an indicator for planetary habitability.

In the solar system, oldhamite (CaS) is generally considered to be formed by the condensation of solar nebula gas. Enstatite chondrites, one of the most important repositories of oldhamite, are believed to be representative of the material that formed Earth. Thus, the formation mechanism and the evolution process of oldhamite are of great significance to the deep understanding of the solar nebula, meteorites, the origin of Earth, and the C-O-S-Ca cycles of Earth.

Relationship of individual and mixed urinary metals exposure with liver function in the China National Human Biomonitoring (CNHBM) of Zhejiang Province.

Background: Heavy metals have been reported to affect liver function. However, there is currently little and inconsistent knowledge about the effects of combined and individual urinary metals on specific parameters of liver function in the general population. Therefore, this study aimed to investigate their associations.

Experimental Study on the Shell: Distinctive Structure and Mechanical Behavior.

, Lamarck, 1819 (Bivalvia Cardiida Cardiidae, known as the fluted giant clam) is one of the largest-sized bivalve shells, which is equipped with a strong and tough bioceramic shell to effectively protect itself from the attack of predators. To better understand the mechanical defense mechanism, the relationship between the microstructure, composition, and mechanical properties of the shell was investigated. We find that the shell is composed of aragonite CaCO and a small portion of organic matter, which are well-arranged, assembling a multiscale, inhomogeneous, and anisotropic structure.

[Establishment and evaluation of identification method for Yersinia pestis and Yersinia pseudotuberculosis].

Objective: To establish a gene identification method of Yersinia pestis and Yersinia pseudotuberculosis for plague surveillance.

Methods: According to the specific genomic sequences of Y. pestis and Y.

Discovery, diversity and evolution of novel coronaviruses sampled from rodents in China.

Although rodents are important reservoirs for RNA viruses, to date only one species of rodent coronavirus (CoV) has been identified. Herein, we describe a new CoV, denoted Lucheng Rn rat coronavirus (LRNV), and novel variants of two Betacoronavirus species termed Longquan Aa mouse coronavirus (LAMV) and Longquan Rl rat coronavirus (LRLV), that were identified in a survey of 1465 rodents sampled in China during 2011-2013. Phylogenetic analysis revealed that LAMV and LRLV fell into lineage A of the genus Betacoronavirus, which included CoVs discovered in humans and domestic and wild animals.

Ongoing spillover of Hantaan and Gou hantaviruses from rodents is associated with hemorrhagic fever with renal syndrome (HFRS) in China.

Background: Longquan City, Zhejiang province, China, has been seriously affected by hemorrhagic fever with renal syndrome (HFRS) since the first cases were registered in 1974. To understand the epidemiology and emergence of HFRS in Longquan, which may be indicative of large parts of rural China, we studied long-term incidence patterns and performed a molecular epidemiological investigation of the causative hantaviruses in human and rodent populations.

Method/principal Findings: During 1974-2011, 1866 cases of HFRS were recorded in Longquan, including 20 deaths.

[Investigation on the natural infectious status of hantaviruses among small mammals in Longquan city, Zhejiang province].

Objective: To investigate the situation of the natural infection of hantaviruses (HV) in small mammals and to provide evidence for the control and prevention of hemorrhagic fever with renal syndrome (HFRS) in Longquan area, Zhejiang province.

Methods: Small mammals were captured by night trap, and lung tissue samples were collected and stored in liquid nitrogen. HV antigens were detected by indirect immuno-fluorescence assay (IFA).
