Modelling early age hydration kinetics of alite

Karen Scrivener, Shashank Bishnoi, Aditya Kumar

The modelling platform mu ic [1] has been used to investigate the mechanisms occurring during the hydration of alite. It is shown that it is possible to obtain a good simulation of the hydration kinetics through the implementation of two mechanisms: a diss ...

Modelling Hydration Kinetics of Cementitous Systems

Aditya Kumar

The modeling platform µic has been extended to study the hydration of cement based systems. It is shown that the hydration kinetics of alite can be described through the implementation of two mechanisms: a solution controlled dissolution (SCD) mechanism fo ...

A Pyridinol Acyl Cofactor in the Active Site of [Fe]-hydrogenase Evidenced by the Reactivity of Model Complexes

Xile Hu, Dafa Chen, Bowen Hu

The decomposition reaction of a water-soluble complex (see scheme; 1) in H2O confirms the existence of a unique bidentate pyridinol cofactor in [Fe]-hydrogenase. This unique moiety is confirmed for the first time by the decomposition of a well-defined mode ...

Utilization of Silicate Minerals for pH Control during In Situ Bioremediation of Chlorinated Solvents

David Andrew Barry, Christof Holliger, Alessandro Brovelli, Elsa Marina Lacroix

Background/Objectives. Chloroethenes such as tetrachloroethene (PCE) and trichloroethene (TCE) are among the most prevalent contaminants in groundwater due to their extensive use in industrial processes. In situ bioremediation (ISB) is an attractive techno ...

New Bisaqua Picolinate-Based Gadolinium Complexes as MRI Contrast Agents with Substantial High-Field Relaxivities

Lothar Helm, Marinella Mazzanti

Two new tripodal heptadentate ligands, H4dpaba (N,N'-bis[(6-carboxypyridin-2-yl)methyl]aspartic acid) and H3mpatcn(1,4-bis(methoxycarbonyl)-7-[(6-carboxypyridin-2-yl)methyl]-1,4,7-triazacyclononane), which bear one or two picolinate pendant arms, have been ...

Game-theoretic Models of Web Credibility

Karl Aberer

Research on Web credibility assessment can significantly benefit from new models that are better suited for evaluation and study of adversary strategies. Currently employed models lack several important aspects, such as the explicit modeling of Web content ...

Carbon monoxide as a tracer of gas transport in snow and other natural porous media

Wolf Hendrik Huwald, Marc Parlange, Marc Calaf Bracons, Nicolaas Cornelis van de Giesen, Scott W. Tyler

The movement of air in natural porous media is complex and challenging to measure. Yet gas transport has important implications, for instance, for the evolution of the seasonal snow cover and for water vapor transport in soil. A novel in situ multi-sensor ...

Interface reactions and stability of a hydride composite (NaBH4 + MgH2)

Shunsuke Kato

The use of the interaction of two hydrides is a well-known concept used to increase the hydrogen equilibrium pressure of composite mixtures in comparison to that of pure systems. The thermodynamics and reaction kinetics of such hydride composites are revie ...

NMR Study of Ligand Exchange and Electron Self-Exchange between Oxo-Centered Trinuclear Clusters [Fe3(μ3-O)(μ-O2CR)6(4-R´py)3]+/0

André Merbach, Lothar Helm

The syntheses, single crystal X-ray structures, and magnetic properties of the homometallic mu(3)-oxo trinuclear clusters Fe-3(mu(3)-O)(mu-O2CCH3)(6)(4-Phpy)(3) (1) and F(e)3(mu(3)-O)(mu-O(2)CAd)(6)(4-Mepy)(3) (2) are reported (Ad = adamanta ...

Beyond Transition State Theory: Accurate Description of Nuclear Quantum Effects on the Rate and Equilibrium Constants of Chemical Reactions Using Feynman Path Integrals

Jiri Vanicek

Nuclear tunneling and other nuclear quantum effects have been shown to play a significant role in molecules as large as enzymes even at physiological temperatures. I discuss how these quantum phenomena can be accounted for rigorously using Feynman path int ...
