A molecular probe for the optical detection of biogenic amines

Rosario Scopelliti, Kay Severin, Bo Ram Lee

A coumarin derivative was employed for the detection of biogenic amines in buffered aqueous solution by UV-Vis or fluorescence spectroscopy. Incorporated in a polymeric matrix, the dye can also be used for the optical detection of gaseous amines. ...

Evolution of algal toxicity during (photo)oxidative degradation of diuron

Urs von Gunten, Kristin Schirmer, Silvio Canonica

In the aquatic environment and in engineered water treatment systems, organic contaminants can undergo oxidative and photochemical transformations. For an overall risk assessment, the toxicity of the resulting transformation products has to be investigated ...

Effects of sonochemical parameters and inorganic ions during the sonochemical degradation of crystal violet in water

César Pulgarin, Fernando Guzman Duque

This work deals with the ultrasonic degradation (800 kHz) of crystal violet (CV) under different experimental conditions. The effects of saturating gas (argon, carbon dioxide and air), CV concentration (2.45-1225 mu mol L-1), pH (3-9) and power (20-80 W) w ...

Deciphering Three Beneficial Effects of 2,2 '-Bipyridine-N,N '-Dioxide on the Luminescence Sensitization of Lanthanide(III) Hexafluoroacetylacetonate Ternary Complexes

Jean-Claude Bünzli, Svetlana Eliseeva

Lanthanide hexafluoroacetylacetonate ternary complexes with 2,2'-bipyridine-N,N'-dioxide, [Ln(hfa)3(bpyO2)], were synthesized for Ln = Eu, Gd, Tb, and Lu and fully characterized by elemental, thermal, and mass-spectrometric analyses. The X-ray crystal stru ...

Metal-Organic Frameworks as Adsorbents for Hydrogen Purification and Precombustion Carbon Dioxide Capture

Berend Smit

Selected metal-organic frameworks exhibiting representative properties-high surface area, structural flexibility, or the presence of open metal cation sites-were tested for utility in the separation of CO2 from H 2 via pressure swing adsorption. Single-com ...

Dioxygen Reduction by Cobalt(II) Octaethylporphyrin at Liquid / Liquid Interfaces

Hubert Girault, Manuel Alejandro Méndez Agudelo, Bin Su, Raheleh Partovi Nia, Zdenek Samec

Oxygen reduction catalyzed by cobalt(II) (2,3,7,8,12,13,17,18-octaethylporphyrin) [Co(OEP)] at soft interfaces is studied by voltammetry and biphasic reactions. When Co(OEP) is present in a solution of 1,2-dichloroethane in contact with an aqueous acidic s ...

A Fluorescent Sensor for Pyrophosphate Based on a Pd(II) Complex

Rosario Scopelliti, Kay Severin, Jie Gao

A mixture of the Pd(II) complex [Pd(NO3)2(bipy)] (bipy = 2,2-bipyridine) and the fluorescent dye Methylcalcein blue (MCB) constitutes a chemosensing ensemble which can be used for the detection of pyrophosphate (PPi) by fluorescence spectroscopy. The senso ...

Direct and mediated electrochemical oxidation of ammonia on boron-doped diamond electrode

Christos Comninellis, Agnieszka Kapalka

Direct (non-mediated) electrochemical oxidation of ammonia on boron-doped diamond (BDD) electrode proceeds mainly at high pH (>8) via free ammonia (NH3) oxidation. To enhance ammonia oxidation on BDD at low pH (

Turn-Off-and-On: Chemosensing Ensembles for Sensing Chloride in Water by Fluorescence Spectroscopy

Kay Severin, Kurt Schenk

The recognition and sensing of aqueous chloride by synthetic receptors is a challenging task. Herein we apply the chemosensing ensemble methodology to optically detect chloride in water at near physiological pH. Variants based on two closely related recept ...
