Uranium from the sea provides a long-time supply guarantee of nuclear fuels for centuries to come, and the neutral Ca2UO2(CO3)3 complex has been shown to be the dominant species of uranium in seawater. However, the solvation and structure of the Ca2UO2(CO3)3 complex in seawater have been unclear. Herein we simulate the Ca2UO2(CO3)3 complex in a model seawater solution via classical molecular dy...

A series of heterometallic magnesium diruthenium(ii,iii) carbonates, namely K{Mg(H2O)6}2[Ru2(CO3)4Cl2]·4H2O (1), K2[{Mg(H2O)4}2Ru2(CO3)4(H2O)Cl]Cl2·2H2O (2), K[Mg(H2O)5Ru2(CO3)4]·5H2O (3) and K[Mg(H2O)4Ru2(CO3)4]·H2O (4), were synthesized from the reaction of Ru2(CO3)4(3-) and Mg(2+) in aqueous solution. Compound 1 is composed of ionic crystals with the Ru2(CO3)4Cl2(5-) : Mg(H2O)6(2+) : K(+) ra...

Co3 O4 , which is of mixed valences Co(2+) and Co(3+) , has been extensively investigated as an efficient electrocatalyst for the oxygen evolution reaction (OER). The proper control of Co(2+) /Co(3+) ratio in Co3 O4 could lead to modifications on its electronic and thus catalytic properties. Herein, we designed an efficient Co3 O4 -based OER electrocatalyst by a plasma-engraving strategy, which...

Co3 O4 -modified CeO2 (Co/Ce 1:4) was prepared by a combination of sol-gel processing and solvothermal treatment. The distribution of Co was controlled by means of the synthesis protocol to yield three different morphologies, namely, Co3 O4 nanoparticles located on the surface of CeO2 particles, coexistent Co3 O4 and CeO2 nanoparticles, or Co oxide structures homogeneously distributed within Ce...

A new nonlinear optical (NLO) material, RbNa5Ca5(CO3)8, has been synthesized by the hydrothermal method. The crystal structure is established by single-crystal X-ray diffraction. RbNa5Ca5(CO3)8 crystallizes in the hexagonal crystal system with space group P63mc (No. 186). The structure of RbNa5Ca5(CO3)8 can be described as the adjacent infinite [CaCO3]∞ layers lying in the a-b plane bridged thr...

Reactions of [Zn(L)(H2O)] precursor and EuCl3 with the aid of CO3(2-) ions derived from atmospheric CO2 affording an unusual heteropolynuclear cluster [Zn4L4Eu4(CO3)6]·EtOH. In the core of the cluster, four hetero-binuclear [ZnLEu] units linked by six CO3(2-) anions forms a well defined [Zn4Eu4] skeleton with good planarity, which plays an important role in stabilizing the cluster.

A series of novel rare earth carbonates, RE3(OH)6(CO3)Cl (RE = Dy, Er, Y), with sodalite-like (SOD-like) zeolite topologies have been successfully synthesized by introducing an appropriate amount of CO3(2-) from NaCO3 or atmospheric carbon dioxide as a template. Single-crystal X-ray diffraction reveals that the structure consists of the RE3(OH)6(3+) cationic framework with a SOD-like topology b...

BACKGROUND The current study utilized a Bleomycin-induced model of skin fibrosis to investigate the neo-epitope CO3-610 (KNGETGPQGP), a fragment of collagen III released during matrix metalloproteinase-9 (MMP9) degradation of the protein, we have previously described as a novel biomarker for liver fibrosis. The aim was to investigate CO3-610 levels in another well characterised model of fibrosi...

Using quantitative polymerase chain reaction (QPCR), the relative transcriptional levels of cytochrome c oxidase subunit 3 (CO3) were studied in Aedes aegypti in response to treatment with acetone, permethrin, and fipronil. The transcriptional levels of CO3 were significantly (P < 0.05) higher in acetone-treated Ae. aegypti compared with that in untreated samples. Using ribosomal L24, heat shoc...

[1] Broecker and Clark [2002] use the ‘‘size normalized weight’’ of planktic foraminifera to estimate the carbonate ion concentration ([CO3 ]) of Atlantic glacial upper deep water. This method was introduced by Lohmann [1995] and is based on the fact that, within a defined size fraction, dissolution decreases shell weight in proportion to the degree of undersaturation with respect to CaCO3.
