A robust extra-large microporous coordination polymer with a Kagomé type structure was synthesized by carboxylate/amine multifunctional ligand with a Cu2+ cluster and the hexagonal 1D channels (approximately 15 A) showed type I and IV adsorption isotherms for gas molecules.

In the Hydrogen based economy, distributed power generation systems using fuel cell technology require modularity. This modularity in power generation can be achieved by process intensification of the equipments involved. The water gas shift reaction is an integral part of hydrocarbon based Hydrogen generation and the reaction is kinetically limited and hence occupies the largest volume. Proces...

Use of preformed metal-organic polyhedra (MOPs) as supermolecular building blocks (SBBs) for the synthesis frameworks (MOFs) remains underexplored due to lack robust functionalized MOPs. Herein we report use polycarboxylate cuboctahedral RhII-MOPs constructing highly-connected MOFs. Cuboctahedral MOPs were with carboxylic acid groups on their 12 vertices or 24 edges through coordinative covalen...

The asymmetric unit of the title compound, [Zn 2 (C 9 H 3 O 6 )(NO )(C 5 NO) ] n , I consists two different zinc(II) ions bridged by carboxylate group benzene-1,3,5-tricarboxylate (BTC 3− ). Zn1 center is tetra-coordinated atoms three symmetrically equivalent BTC anions and one nitrate atom in a distorted tetrahedral geometry with Zn—O bond lengths (average value 1.958 Å) slightly shorter than ...

In the introduction to this paper, characteristics of Góreckie lake and construction operation wind-driven pulverizing aerator are presented. The purpose manuscript is determine efficiency unit in windy conditions Lake. pulverization depends on wind at lake.

The article discusses the separation process efficiency issue of fine powders in an air separator. aerodynamic scheme separator is proposed and schemes gas-material flow through elements path are considered. equations motion proposed. calculation various operating modes results approximate graphical-analytical for presented. A high convergence theoretical positions with performed experiments sh...

A simple and robust on-line sequential insertion system coupled with hydride generation atomic absorption spectrometry (HG-AAS) was developed, for selective As(III) and total inorganic arsenic determination without pre-reduction step. The proposed manifold, which is employing an integrated reaction chamber/gas–liquid separator (RC-GLS), is characterized by the ability of the successful managing...

The title dinuclear complex, [Cu2(C6H11O2)4(C6H4N2)2], has a paddle-wheel structure. The two crystallographically independent Cu(II) atoms are each in a distorted square-pyramidal environment, in which four O atoms from the four bridging caproate ligands form the basal plane and the pyridine N atom of the 4-cyano-pyridine ligand occupies the apical position. The Cu⋯Cu distance is 2.6055 (9) Å. ...

The paddle-wheel-type centrosymmetric dinuclear title complex, [Zn(2)(C(7)H(5)O(2))(4)(C(12)H(10)N(2))(2)], contains four bridging benzoate groups and two terminal trans-1-(2-pyrid-yl)-2-(4-pyrid-yl)ethyl-ene (L) ligands. The inversion center is located between the two Zn(II) atoms. The octa-hedral coordination around the Zn(II) atom, with four O atoms in the equatorial plane, is completed by a...
