Potentiometric E-Tongue System for Geosmin/Isoborneol Presence Monitoring in Drinkable Water.

Larisa Lvova et al.

Sensors (Basel, Switzerland), 20(3) (2020-02-09)

A potentiometric E-tongue system based on low-selective polymeric membrane and chalcogenide-glass electrodes is employed to monitor the taste-and-odor-causing pollutants, geosmin (GE) and 2-methyl-isoborneol (MIB), in drinkable water. The developed approach may permit a low-cost monitoring of these compounds in concentrations

Development of Organic-Inorganic Hybrid Optical Gas Sensors for the Non-Invasive Monitoring of Pathogenic Bacteria.

Sumana Kladsomboon et al.

Sensors (Basel, Switzerland), 18(10) (2018-09-23)

Hybrid optical gas sensors, based on different organic and inorganic materials, are proposed in this paper, with the aim of using them as optical artificial nose systems. Three types of organic and inorganic dyes, namely zinc-porphyrin, manganese-porphyrin, and zinc-phthalocyanine, were

Detection of meat-borne trimethylamine based on nanoporous colorimetric sensor arrays.

Huang Xiao-wei et al.

Food chemistry, 197(Pt A), 930-936 (2015-12-01)

Trimethylamine (TMA) is a key measurement indicator for meat spoilage. In order to develop simple, cheap, and sensitive sensors for TMA detection, a nanoporous colorimetric sensor array (NCSA) was developed. A sol-gel method has been used to obtain TiO2 nanoporous

High-frequency and -field electron paramagnetic resonance of high-spin manganese(III) in tetrapyrrole complexes.

J Krzystek et al.

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 58(6), 1113-1127 (2002-05-08)

High-field and -frequency electron paramagnetic resonance (HFEPR) spectroscopy has been used to study three complexes of high spin Manganese(III), 3d4, S = 2. The complexes studied were tetraphenylporphyrinatomanganese(III) chloride (MnTPPCI), phthalocyanatomanganese(III) chloride (MnPcCl), and (8,12-diethyl-2,3,7,13,17,18-hexamethylcorrolato)manganese(III) (MnCor). We demonstrate the ability

A new decomposition mechanism for metal complexes under water-oxidation conditions.

Mohammad Mahdi Najafpour et al.

Scientific reports, 9(1), 7483-7483 (2019-05-18)

Herein, water-oxidation reaction by cobalt(II) phthalocyanine, N,N'-bis (salicylidene) ethylenediamino cobalt(II), nickel(II) Schiff base (N,N'-bis (salicylidene)ethylenediamino nickel(II), nickel(II)) phthalocyanine-tetrasulfonate tetrasodium, manganese(II) phthalocyanine, 5,10,15,20-Tetraphenyl-21H,23H-porphine manganese(III) chloride, manganese(III) 5,10,15,20-tetra(4-pyridyl)-21H,23H-porphine chloride tetrakis(methochloride) was investigated using electrochemistry, UV-vis spectroscopy and spectroelectrochemistry. According to our results

Chloro(5,10,15,20-tetraphenylporphyrinato)manganese(III) with 4/m symmetry.

B Cheng et al.

Acta crystallographica. Section C, Crystal structure communications, 52 ( Pt 2), 361-363 (1996-02-15)

The crystal structure of [Mn(TPP)Cl] in space group I4/m (where TPP is C44H28N4) has been determined. The unit cell contains two full molecules, with one eighth of a molecule unique. An out-of-plane model for the Mn atom was applied and

Mild and efficient oxidation of Hantzsch 1,4-dihydropyridines with sodium periodate catalyzed by a new polystyrene-bound Mn(TPP)Cl.

Majid Moghadam et al.

Bioorganic & medicinal chemistry letters, 16(7), 2026-2030 (2006-01-24)

Mild and efficient oxidation of Hantzsch 1,4-dihydropyridines with sodium periodate catalyzed by Mn(TTP)Cl supported on polystyrene-bound imidazole is reported. This heterogeneous catalyst is of great stability and reusability in the oxidation of 1,4-dihydropyridines with sodium periodate without significant loss of
