Deterioration of mortar bars immersed in magnesium containing sulfate solutions

Karen Scrivener, Wolfgang Kunther, Barbara Lothenbach

Mortars prepared with a CEM I and a CEM III/B binder were investigated in different magnesium sulfate solutions. The main deterioration mechanism for the CEM I was expansion, while surface erosion was dominant for CEM III/B. The presence of sodium, potassi ...

Mechanism of expansion of mortars immersed in sodium sulfate solutions

Karen Scrivener, Cheng Yu, Wei Sun

The mechanisms behind the expansion of samples immersed in solutions containing sulfate ions have been controversial. Expansion is believed to originate in the formation of ettringite, but it is not possible to find any direct correlation between these two ...

Synthetic calibrators for the analysis of sulfoconjugated metanephrines in urine: hydrolysis conditions revisited

Sandrine Gerber, Jonathan Simonin

Background: The quantification of total (free + sulfated) metanephrines in urine is recommended to diagnose pheochromocytoma. Urinary metanephrines include metanephrine itself, normetanephrine and methoxytyramine, mainly in the form of sulfate conjugates ( ...

Application of a Versatile Nanoparticle Stabilizer in Phase Transfer and Catalysis

Paul Joseph Dyson, Vincent Laporte, Ilaria Biondi

Gold and rhodium nanoparticles stabilized by a cationic polymer can be readily modified by anion exchange to afford nanoparticles that may be dispersed in a wide range of organic solvents and ionic liquids. The catalytic activity of the Rh nanoparticle dis ...

Study of Amyloid beta-Peptide (A beta 12-28-Cys) Interactions with Congo Red and beta-Sheet Breaker Peptides Using Electrochemical Impedance Spectroscopy

Hubert Girault, Raheleh Partovi Nia

A surface-based approach is presented to study the interactions of A beta 12-28-Cys assembled on gold surfaces with Congo red (CR) and a beta-sheet breaker (BSB) peptide. The various aspects of the peptide film have been examined using different electroche ...

Mechanistic studies on two dinuclear organogold(III) compounds showing appreciable antiproliferative properties and a high redox stability

Angela Casini

Two dinuclear oxo-bridged organogold(III) compounds, namely [(N,N,C)(2)Au-2(mu-O)]PF6 (with N,N,CH = 6-(1-methylbenzyl)-2,2'-bipyridine, Au(2)O1; or 6-(1,1-dimethylbenzyl)-2,2'-bipyridine, Au(2)O2), were previously prepared and characterised. Their so ...
