In recent years, a number of reactions leading to the liberation of inorganic pyrophosphate have been described. Since the only known reaction leading to a net decrease in the concentration of inorganic pyrophosphate is that of hydrolysis, the properties of inorganic pyrophosphatases are of interest. The discovery of an inorganic pyrophosphatase in muscle was made by Lohmann (2) and one was dem...

In this study, we used a 6-methyl-2,3-pyridine dicarboxylate ligand to develop the frameworks. Two novel compounds, [Zn2(L)2(H2O)4] (1) and [Cd(L)(H2O)] (2) (where L = 6-methyl-pyridine-2,3-dicarboxylate) were produced. The compounds characterized by elemental analysis, powder X-ray diffraction, Fourier-transform infrared spectroscopy single crystal crystallography. We successfully tuned framew...

Functional photoluminescent materials are emerging as a fascinating subject with versatile applicability. In this work, luminescent organic-inorganic hybrid hydrogels are facilely designed through supramolecular self-assembly of sodium cholate, and lanthanide ions such as Eu(3+), Tb(3+), and Eu(3+)/Tb(3+). Fluorescence microscopy and TEM visualization demonstrates the existence of spontaneously...

the recognition of the biologically and environmentally important ions is of great interest in the field of chemical sensors in recent years. the fluorescent sensors as a powerful optical analytical technique for the detection of low level of various analytes such as anions and metal cations have been progressively developed due to the simplicity, cost effective, and selectivity for monitoring ...

Lanthanide ions can mediate both phosphomonoester hydrolysis and beta-elimination of inorganic phosphate from polypeptide substrates under near-physiological conditions of pH, temperature, and salt.

Ion-adsorbed rare earth minerals have ions adsorbed on the surfaces of clay such as kaolinite and high contents medium heavy elements. They are important resources supporting development high-tech industries. In this study, CASTEP module in Materials Studio was used to study adsorption ion Y(III) interface (Al-OH)-H2O (Si-O)-H2O with density functional theory. The monitoring calculation chemica...

This paper reports new insights on the role of the inorganic composition of Bone char (BC) on its sorption properties for the removal of heavy metals Cd, Ni, and Zn ions from aqueous solution. In particular, we showed the importance of both composition and surface chemistry of BC on its sorption properties for the removal of these metal ions in aqueous solution. Results of physicochemical chara...

Three new heteroleptic copper(II) complexes, [(tmen)Cu(dike)H2O]X where tmen = N,N,N',N'-tetramethylethylenediamine, dike = 2-acetylcyclopentanone anion and X= ClO4- (1), Cl- (2) and Br- (3) are prepared and characterized by elemental analyses, molar conductance measurements and IR and UV-Vis spectroscopy techniques. The complex 1 is fairly soluble in various organic solvents and demonstrates d...

By use of different inhibitors as well as atomic absorption spectrophotometry it has been shown that the haemolymph-acetylcholinesterase (E. c. 3.1.1.7) of the sea mussel Mytilus edulis is a metalloprotein containing 2,95 Fe2+-ions per subunit. All inhibitors used (1,10-phenanthroline, salicylic aldehyde, 2,2'-dipyridyl, 8-hydroxyquinoline) showed a non-competitive inhibition, which was not pH-...
