Standard-Free Quantification of Dicarboxylic Acids: Case Studies with Salt-Rich Effluents and Serum

Christian Ludwig, Daniil Salionov, Sasa Bjelic

The present study evaluates the ionization efficiency (IE) of linear and branched C2–C14 dicarboxylic acids (DCAs) by electrospray ionization (ESI) under different conditions. The influence of the concentration of organic modifier (MeOH); mobile phase addi ...

Enzyme and Acid Deconjugation of Plasma Sulfated Metanephrines

Sandrine Gerber

Background: Total (i.e. free + sulfated) metanephrines in plasma is a biomarker for the diagnosis of pheochromocytoma/paraganglioma. Sulfated metanephrines must be completely deconjugated by perchloric acid hydrolysis or sulfatase treatment prior to analyt ...

Inorganic salts interact with oxalic acid in submicron particles to form material with low hygroscopicity and volatility

Athanasios Nenes

Volatility and hygroscopicity are two key properties of organic aerosol components, and both are strongly related to chemical identity. While the hygroscopicities of pure salts, di-carboxylic acids (DCA), and DCA salts are known, the hygroscopicity of inte ...

Size-Controlled Pd Nanoparticles in 2-Butyne-1,4-diol Hydrogenation: Support Effect and Kinetics Study

Lioubov Kiwi, Fernando Cardenas Lizana, Charline Berguerand

Structured catalyst has been developed for C–C triple bond three-phase hydrogenation. The sintered metal fiber (SMF) coated by different oxides served as support for monodispersed Pd nanoparticles (6.4 ± 0.5 nm). The effect of acid–base properties and redu ...

Photocatalytic production of O-1(2) and (OH)-O-center dot mediated by silver oxidation during the photoinactivation of Escherichia coli with TiO2

César Pulgarin, Andrzej Sienkiewicz

Ag loaded TiO2 was applied in the photocatalytic inactivation of Escherichia coil under ultraviolet (UV) and visible (Vis) light irradiations. Ag enhanced the TiO2 photodisinfecting effect under Vis irradiation promoting the formation of singlet oxygen and ...

Labelling cell structures and tracking cell lineage in zebrafish using SNAP-tag

Kai Johnsson, Sambashiva Banala, Mako Kamiya

We present a method for the specific labelling of fusion proteins with synthetic fluorophores in Zebrafish. The method uses the SNAP-tag technology and O-6-benzylguanine derivatives of various synthetic fluorophores. We demonstrate how the method can be us ...

Striking Influence of the Catalyst Support and Its Acid–Base Properties: New Insight into the Growth Mechanism of Carbon Nanotubes

Arnaud Magrez, Gabor Laurenczy, Endre Horvath, Jin Won Seo, Rita Smajda, Donatello Acquaviva, Juan Carlos Andresen

In the accepted mechanisms of carbon nanotube (CNT) growth by catalytic chemical vapor deposition (CCVD), the catalyst support is falsely considered as a passive material whose only role is to prevent catalytic particles from coarsening. The chemical chang ...

On the photocatalytic degradation of phenol and dichloroacetate by BiVO4: The need of a sacrificial electron acceptor

César Pulgarin, Laura Ding, Nikola Castillo, Andre Heel

The photodegradation of phenol and dichloroacetic acid (DCAA) by \ce{BiVO4} was studied in the absence as well as presence of selected electron scavengers. The experiments were performed under the visible (vis) irradiation of aqueous solutions over a wide ...

Transient kinetics and in situ spectroscopic techniques for the characterisation of V/Ti-oxide catalysts in toluene partial oxidation

Fabio Rainone

Development of selective oxidation catalysts is a major concern of modern chemical industry. Among several systems, VTi-oxide based catalysts showed the most promising and versatile, able to catalyse key reactions like oxidation of o-xylene to phtalic anhy ...

Continuous monitoring of enzymatic whey protein hydrolysis. Correlation of base consumption with soluble nitrogen content

Albert Renken, Antoine Margot

The optimization of enzymatic protein hydrolysis often represents a tedious task due to complicated analytical methods. The simplest system of continuous analysis consists of monitoring the base consumption during a pH-controlled reactor operation. However ...
