Thermodynamic Analysis of Biodegradation Pathways

Vassily Hatzimanikatis, Stacey Deleria Finley

Microorganisms provide a wealth of bio-degradative potential in the reduction and elimination of xenobiotic compounds in the environment. One useful metric to evaluate potential biodegradation pathways is thermodynamic feasibility. However, experimental da ...

Characterization of surface functional groups present on laboratory-generated and ambient aerosol particles by means of heterogeneous titration reactions

Michel Rossi, Michel Guillemin

A Knudsen flow reactor has been used to quantify surface functional groups on aerosols collected in the field. This technique is based on a heterogeneous titration reaction between a probe gas and a specific functional group on the particle surface. In the ...

Structure of the Orthorhombic gamma-Phase and Phase Transitions of Ca(BD4)(2)

Philippe Mauron

We have solved and refined the crystal structure of the orthorhombic gamma-phase of Ca(BD4)(2) by combined synchrotron X-ray powder diffraction, neutron powder diffraction, and ab initio calculations. Among five structural candidates giving the same qualit ...

Dynamics and disorder in surfactant-templated silicate layers studied by solid-state NMR dephasing times and correlated line shapes

David Lyndon Emsley, Bradley Floyd Chmelka

Surfactant-templated layered silicates are shown to possess complex compositional, structural, and dynamic features that manifest rich and interrelated order and disorder at molecular length scales. Temperature-dependent 1D and 2D solid-state Si-29 NMR mea ...

Triboelectrochemical techniques and interpretation methods in tribocorrosion: A comparative evaluation

Stefano Mischler

Tribocorrosion is a material deterioration or transformation resulting from simultaneous action of wear and corrosion. Tribocorrosion is found in many engineering applications but the involved mechanisms are still little understood. The investigation of tr ...

Effects of chlorine residue in atomic layer deposition hafnium oxide: A density-functional-theory study

Wei Chen, Min Xu

Hafnium tetrachloride is one of the most commonly used precursors for atomic layer deposition of HfO2. According to the experimental result, chlorine residue is almost unavoidably incorporated during the deposition process. We performed first-principles ca ...

Photodissociation of Alkyl Iodides in Helium Nanodroplets II: Solvation Dynamics

Marcel Drabbels, Andreas Braun

The solvation dynamics of non-thermal species in liquid helium has been investigated by photolyzing alkyl iodide molecules, CH3I, C2H5I and CF3I, embedded in helium nanodroplets. The iodine and CH3 fragments are found to leave the droplets solvated by a fi ...

3-D Shape Estimation of DNA Molecules from Stereo Cryo-Electron Micro-Graphs Using a Projection-Steerable Snake

Michaël Unser, Thierry Blu, Mathews Jacob

We introduce a three-dimensional (3-D) parametric active contour algorithm for the shape estimation of DNA molecules from stereo cryo-electron micrographs. We estimate the shape by matching the projections of a 3-D global shape model with the micrographs; ...

Simultaneous microbial reduction of iron(III) and arsenic(V) in suspensions of hydrous ferric oxide

Janet Gordon Hering

Bacterial reduction of arsenic(V) and iron(III) oxides influences the redox cycling and partitioning of arsenic (As) between solid and aqueous phases in sediment-porewater systems. Two types of anaerobic bacterial incubations were designed to probe the rel ...
