The role of aluminium from supplementary cementitious materials in controlling alkali-silica reaction

Alkali silica reaction (ASR) is a long-term reaction between certain aggregates containing amorphous silicate phases and the alkalis from the cement paste. These silicates react with the alkalis present in the pore solution of the cement paste and form an ...

Evaluation of silicate minerals for pH control during bioremediation: Application to chlorinated solvents

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

Accurate control of groundwater pH is of critical importance for in situ biological treatment of chlorinated solvents. This study evaluated a novel approach for buffering subsurface pH that relies on the use of silicate minerals as a long-term source of al ...

Numerical modeling of field scale application of ground silicate minerals for groundwater pH buffering

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

Recently, it was shown that ground silicate minerals are a potentially suitable pH buffering material for contaminated soils undergoing acidification, for example due to acid mine leachate and coal pile runoff infiltration, as well as during the degradatio ...

Compliant membranes improve resolution in full-wafer micro/nanostencil lithography

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Andreea Veronica Savu, Oscar Vazquez Mena, Katrin Sidler Arnet

This work reports on a considerable resolution improvement of micro/nanostencil lithography when applied on full-wafer scale by using compliant membranes to reduce gap-induced pattern blurring. Silicon nitride (SiN) membranes are mechanically decoupled fro ...

Utilization of silicate minerals for pH control during in situ bioremediation of chlorinated solvent

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

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 technology for removal of the ...

Oxidative dissolution of biogenic uraninite in groundwater at Old Rifle, CO

Rizlan Bernier-Latmani, Elena Suvorova Buffat, Harish Veeramani

Reductive bioremediation is currently being explored as a possible strategy for uranium-contaminated aquifers such as the Old Rifle site (Colorado). The stability of U(IV) phases under oxidizing conditions is key to the performance of this procedure. An in ...

Buffering agent for pH control during in situ bioremediation of chlorinated solvent source zones

David Andrew Barry, Christof Holliger, Elsa Marina Lacroix

Chloroethenes such as tetrachloroethene (PCE) and trichloroethene (TCE) are among the most prevalent contaminants in groundwater. Because of their low aqueous solubility, PCE and TCE are often present as dense non aqueous phase liquid (DNAPL) that can act ...

Surface Enhanced NMR Spectroscopy by Dynamic Nuclear Polarization

David Lyndon Emsley, Geoffrey Bodenhausen, Pascal Miéville, Moreno Lelli, Marc Anthony Caporini, David Benjamin Roger Antoine Gajan, Mehdi Ahmadi

It is shown that surface NMR spectra can be greatly enhanced using dynamic nuclear polarization. Polarization is transferred from the protons of the solvent to the rare nuclei (here carbon-13 at natural isotopic abundance) at the surface, yielding at least ...
