Convenient and simple procedures for the synthesis of functionalized Quinoxaline derivatives were developed via one-pot four-component reaction of o-aminoanilin, acetylenic ester, and malonyl dichloride in the presence of K2 CO3 as effective base catalyst. These compounds widely are used in various industries like paint, pharmaceutical and medicine. Quinoxaline derivatives are also part of anti...
Naphtha was separated by using a easily attainable metal–organic framework, Co3(HCOO)6, through selective molecular exclusion of alkane isomers with different degrees branching. The separation capability the compound evaluated naphtha mixtures 180+ hydrocarbon components. Co3(HCOO)6 exhibited efficient mixture and thus yielded products high octane ratings dynamic capacity. More information can ...
The survival of isolated small populations is threatened by both demographic and genetic factors. Large carnivores declined for centuries in most of Europe due to habitat changes, overhunting of their natural prey and direct persecution. However, the current rewilding trends are driving many carnivore populations to expand again, possibly reverting the erosion of their genetic diversity. In thi...
Lanthanite-(Nd), ideally Nd2(CO3)3·8H2O [dineodymium(III) tricarbonate octa-hydrate], is a member of the lanthanite mineral group characterized by the general formula REE2(CO3)3·8H2O, where REE is a 10-coordinated rare earth element. Based on single-crystal X-ray diffraction of a natural sample from Mitsukoshi, Hizen-cho, Karatsu City, Saga Prefecture, Japan, this study presents the first struc...
The rhythmogenic capacity of the tail-innervating segments (L4-Co3) of the spinal cord was studied in isolated spinal cord and tail-spinal cord preparations of neonatal rats. Bath-applied serotonin/N-methyl-D-aspartate (NMDA) failed to produce a robust sacrococcygeal rhythmicity following midlumbar transection of the spinal cord. By contrast, a regular alternating left-right rhythm could be ind...
The rapid kinetics of bacterial U(VI) reduction and low solubility of uraninite (UO2,cr) make this process an attractive option for removing uranium from groundwater. Nevertheless, conditions that may promote or inhibit U(VI) reduction are not well-defined. Recent descriptions of Ca-UO2-CO3 complexes indicate that these species may dominate the aqueous speciation of U(VI) in many environments. ...
We discuss the sources of radionuclides in the environment and summarise the level of radioactive contaminations world-wide. We delineate how X-ray absorption spectroscopy (XAS) can be used in molecular-level environmental radionuclide research and demonstrate the technique’s application on the following three research topics related to contaminations from uranium mining: 1. The structure of a ...
