Two novel lanthanoid thioantimonates [Sm(4)(tepa)(4)(μ-η(2),η(3)-Sb(3)S(7))(2)(μ-Sb(2)S(4))] (1, tepa = tetraethylenepentamine) and [Eu(2)(tepa)(2)(μ-SbS(3))(μ-OH)](2)(SbS(4))(OH)·H(2)O (2) were solvothermally synthesized. Compound 1 represents the only example of different types of [Sb(3)S(7)](5-) and [Sb(2)S(4)](2-) anions coexisting in the same lanthanoid thioantimonate framework, while 2 di...

One novel 1-D europium thioindate-thioantimonate {[Eu(tepa)](2)[μ(2)-SbS(3)](μ(2)-H(2)O)}[Eu(tepa)In(4)S(9)]·0.25tepa (1, tepa = tetraethylenepentamine) has been solvothermally synthesized. 1 represents the first example of the coordination of a soft Lewis basic 1-D polymeric [In(4)S(9)(6-)](n) ligand to a hard Lewis acidic Eu(3+) ion. The wide-band-gap semiconductor and photoluminescence prope...

MAC it happen : Presented is a study of the synergistic structuredirecting effect of metal–amine complexes (MACs) with different chelating polyamine ligands and imidazolium-based ionic liquid (IL) cations. For the first time, a layered selenidostannate with an asymmetric eight-membered ring, an organic-decorated layered selenidostannate, and a 3D selenidostannate with both the MAC and IL cation...

Macro/mesoporous carbon monoliths with a graphitic framework were synthesized by carbonizing polymeric monoliths of poly(benzoxazine-co-resol). The overall synthesis process consists of the following steps: a) the preparation of polymeric monoliths by copolymerization of resorcinol and formaldehyde with a polyamine (tetraethylenepentamine), b) doping the polymer with a metallic salt of Fe, Ni o...

Copper amine oxidases are important enzymes, which contribute to the regulation of monoand polyamine levels. Each monomer contains one Cu(II) ion and 2,4,5-trihydroxyphenylalanine (TPQ) as cofactors. They catalyze the oxidative deamination of primary amines to aldehydes with a ping-pong mechanism consisting of a transamination. The mechanism is followed by the transfer of two electrons to molec...

choline oxidase (chox) was chosen as a model enzyme for evaluating the performance of cnts’ functional groups for development of enzyme electrodes. cnts were functionalized with carboxylic acid, amine or amide groups. carboxylic acid, amine and amide functionalized cnts were obtained by acid treatment, ethylenediamine or tetraethylenepentamine chemically modification and ammonia plasma treatmen...

The paper reports the development of a microfluidic chip-capillary electrophoresis device using UV/Vis detection for profiling of urinary markers with adjustable on-chip sample dilution. A PMMA polymer microfluidic chip-CE device with on-chip ferrofluid valve control for adjustable sample dilution is developed for profiling of urinary markers related to metabolism disorders for clinical diagnos...
