A new compound, dipotassium holmium(III) phosphate(V) tungstate(VI), K(2)Ho(PO(4))(WO(4)), has been obtained during investigation of the K(2)O-P(2)O(5)-WO(3)-HoF(3) phase system using the flux technique. The compound is isotypic with K(2)Bi(PO(4))(WO(4)). Its framework structure consists of flat (∞) (2)[HoPO(4)] layers parallel to (100) that are made up of (∞) (1)[HoO(8)] zigzag chains inter-li...

The title compound, dinickel(II) strontium bis-[ortho-phosphate(V)] dihydrate, was obtained under hydro-thermal conditions. The crystal structure consists of linear chains (∞) (1)[NiO(2/2)(OH(2))(2/2)O(2/1)] of edge-sharing NiO(6) octa-hedra ( symmetry) running parallel to [010]. Adjacent chains are linked to each other through PO(4) tetra-hedra (m symmetry) and arranged in such a way to build ...

Low-cost and high-performance advanced electrocatalysts for direct methanol fuel cells are of key significance for the improvement of environmentally-pleasant energy technologies. Herein, we report the facile synthesis of cobalt phosphate (Co3(PO4)2) nanospheres by a microwave-assisted process and utilized as an electrocatalyst for methanol oxidation. The phase formation, morphological surface ...

Filter treatment may be a viable means for removing the nitrate (NO3), phosphate (PO4), and pesticides discharged with agricultural drainage waters that cause adverse environmental impacts within the U.S. on local, regional, and national scales. Laboratory batch test screening for agricultural drainage water treatment potential was conducted on 58 industrial product/byproduct filter materials g...

A new iron phosphate, rubidium copper(II) iron(III) bis-(phosphate), RbCuFe(PO4)2, has been synthesized as single crystals by the flux method. This compound is isostructural with KCuFe(PO4)2 [Badri et al. (2011 ▶), J. Solid State Chem. 184, 937-944]. Its structure is built up from Cu2O8 units of edge-sharing CuO5 polyhedra, inter-connected by FeO6 octa-hedra through common corners to form undul...

To reduce the environmental burden of agriculture, suitable methods to comprehend and assess the impact on natural resources are needed. One of the methods considered is the life cycle assessment (LCA) method, which was used to assess the environmental impacts of 18 grassland farms in three different farming intensities — intensive, extensified, and organic — in the Allgäu region in southern Ge...

Global metrics of land cover and land use provide a fundamental basis to examine the spatial variability of human-induced impacts on freshwater ecosystems. However, microscale processes and site specific conditions related to bank vegetation, pollution sources, adjacent land use and water uses can have important influences on ecosystem conditions, in particular in smaller tributary rivers. Comp...

Hydra littoralis and H. attenuata were labelled with Ca, PO4, or [ H]thymidine, either by exposing them to a medium containing the isotope or by injecting the isotope into their gut cavities. Various portions of labelled and unlabelled hydra were grafted together in diverse combinations, and the rate of transfer of radioactivity to the unlabelled portion was assessed. The relative transfer rate...

Numerous biological and chemical studies involve the use of calcium hydroxyapatite (HA), Ca10(PO4)6(OH)2. In this study detailed physicochemical characterization of HA, prepared from an aqueous solution, was carried out employing different methods and techniques: chemical and thermal analyses, x-ray diffraction, infrared and Raman spectroscopies, scanning and transmission microscopies, and Brun...

Fungal tRNA ligase (Trl1) is an essential enzyme that repairs RNA breaks with 2',3'-cyclic-PO4 and 5'-OH ends inflicted during tRNA splicing and non-canonical mRNA splicing in the fungal unfolded protein response. Trl1 is composed of C-terminal cyclic phosphodiesterase and central polynucleotide kinase domains that heal the broken ends to generate the 3'-OH,2'-PO4 and 5'-PO4 termini required fo...
