The title coordination polymer, {[Co2(C15H7O7)(OH)(C14H14N4)]·0.25H2O} n , was synthesized under hydro-thermal conditions. The asymmetric unit contains two Co(2+) ions, one L (3-) anion originating from 5-(4-carb-oxy-phen-oxy)isophthalic acid (H3 L), one OH(-) ligand, one 1,4-bis-[(1H-imidazol-l-yl)meth-yl]benzene (bix) ligand and one disordered lattice water mol-ecule (occupancy 0.25). The two...

POP (prolyl oligopeptidase) specifically hydrolyses a number of small proline-containing peptides at the carboxy end of the proline residue and POP inhibitors have been shown to have cognition-enhancing properties. It has been noted that certain functional groups at the P1 site of the inhibitor, which correspond to the substrate residue on the N-terminal side of the bond to be cleaved, increase...

A series of six Zn(II) tetraphenylporphyrins (ZnTPP), with a phenyl (P) or oligophenyleneethynylene (OPE = (PE) n ) rigid-rod bridge varying in length (9-30 A) and terminated with an isophthalic acid (Ipa) anchoring unit, were prepared as model dyes for the study of sensitization processes on metal oxide semiconductor nanoparticle surfaces (MO(n) = TiO(2), ZnO, and insulating ZrO(2)). The dyes ...

Jute fibers are totally biodegradable and recyclable substances, i.e., environmentally friendly substances. The contemporary annual global production of jute fiber is ready 3. 2 million tons used for diverse packages. Various research being accomplished to discover a suitable substitute the nonbio degradable plastic strengthened composites, which has negative effect at environment. mercerizatio...

Seven Mn(ii) coordination polymers, namely {[Mn2(ptptp)Cl2(H2O)3]·H2O}n (1), {[Mn(μ-ptptp)3]2[Mn3(μ3-Cl)]2}·2Cl·16H2O (2), {[Mn2(ptptp)(ip)2(H2O)3]·H2O}n (3), {[Mn2(ptptp)(5-CH3-ip)2(H2O)3]·H2O}n (4), {[Mn4(ptptp)(5-Br-ip)3(H2O)3]·4H2O}n (5), {[Mn2(ptptp)(Hbtc)(H2O)2]·2H2O}n (6) and {[Mn2(ptptp)(tdc)(H2O)2]·1.5H2O}n (7), have been prepared based on multidentate N-heterocyclic aromatic ligands a...

Poly(ether ketone ketone) (PEKK) is a semicrystalline polymer investigated for highly demanding applications in aerospace, transportation, electronics, and oil & gas industries. The properties required these applications, such as thermomechanical chemical stability, are intimately linked to the crystalline state of material. PEKK exhibits polymorphism that depends, among other factors, on its t...
