The production of dimethyl ether (DME) as compared to methanol from synthesis gas allows for increased conversions in a single pass. A challenge this process is the combination and dehydration functionalities catalyst without mutual negative interference their performances. Here, we studied use hydrated niobium pentoxide (Nb2O5·nH2O) phosphate (NbOPO4) with copper-based direct DME, while gamma-...

Several hybridoma cell lines from mice were established, producing monoclonal antibodies (MAbs) directed against the dissimilatoric copper nitrite reductase (dNIR) to detect actual denitrifying bacteria at the single cell level under nondestructive conditions in the environment. The mice were immunized with native or recombinant enzyme gained from two different bacteria, Ochrobactrum anthropi a...

In the title salt, [Cu(NO(3))(C(7)H(6)N(2))(4)]NO(3), one nitrate anion is coordinated to the Cu(II) atom, which is also coordinated by the N atoms of four N-heterocycles. The geometry at the metal atom is a square pyramid in which the O atom of the anion occupies the apical position [Cu-O = 2.468 (5) and 2.590 (7) Å in the two independent formula units]. The cation lies on a twofold rotation a...

In the title compound, [Cu(C(10)H(8)N(2))(C(18)H(15)P)(2)]NO(2)·CHCl(3)·0.5H(2)O, the Cu atom is tetra-hedrally coordinated by a bidentate 2,2'-bipyridine ligand and two PPh(3) ligands. The Cu-N and Cu-P distances are similar to those observed in similar compounds. The range of coordination angles shows a moderate distortion from ideal tetra-hedral geometry. The bipyridine ligand is twisted [14...

The occurrence of denitrification and nitrate respiration among eukaryotes has been established during the last few decades. However, denitrification-related eukaryotic genes have been isolated from only a few fungi, and eukaryotic denitrification (or nitrate respiration) is still inadequately understood. In this study, we identified genes that were up-regulated under denitrifying conditions in...

Background & Aims of the Study:  Soil and water pollution to heavy metals is a serious threat for environment and human health. Finding an effective way for refining water from these metals is very important. The aim of this study was modifying electrospun polymeric nano fibers and studying its efficiency for copper ion omission in water solutions. Materials & Method...
