Mechanism of Atmospheric CO2 Fixation in the Cavities of a Dinuclear Cryptate

El-Hendawy, Morad M. ; English, Niall J. ; Mooney, Damian A. (ACS Publications, 2012-05-07)

Using density functional theory (DFT) methods, we have investigated two possible mechanisms for atmospheric CO2 fixation in the cavity of the dinuclear zinc (II) octaazacryptate, and the subsequent reaction with methanol ...
Molecular dynamics study of water in contact with TiO2 rutile-110, 100, 101, 001 and anatase-101, 001 surface

Kavathekar, Ritwik S. ; Dev, Pratibha ; English, Niall J. ; MacElroy, J. M. Don (Taylor and Francis, 2011-05-19)

We have carried out classical molecular dynamics of various surfaces of TiO2 with its interface with water. We report the geometrical features of the first and second monolayers of water using a Matsui Akaogi (MA) force ...
Oxygen-mediated regulation of biofilm development is controlled by the alternative sigma factor sigma(B) in Staphylococcus epidermidis

Cotter, John J. ; O'Gara, James P. ; Mack, Dietrich ; Casey, Eoin (ASM, 2009-01)

Using a modified rotating-disk reactor to sparge oxygen to Staphylococcus epidermidis cultures, we found that oxygen negatively regulates biofilm development by influencing the activity of {sigma}B. Under anaerobic conditions, ...
Phase diagrams of microemulsions containing reducing agents and metal salts as bases for the synthesis of metallic nanoparticles

Najjar, Reza ; Stubenrauch, Cosima (Elsevier, 2008-11-21)

We studied the phase diagrams of microemulsions with a view to using these systems for the synthesis of metallic Pt, Pb, and Bi nanoparticles as well as of intermetallic Pt/Pb and Pt/Bi nanoparticles. The microemulsions ...
Phase diagrams of non-ionic microemulsions containing reducing agents and metal salts as bases for the synthesis of bimetallic nanoparticles

Magno, Miguel ; Angelescu, Daniel G. ; Stubenrauch, Cosima (Elsevier, 2009-09)

Phase diagrams of microemulsions containing metal salt(s) and reducing agent, respectively, were studied in detail. The microemulsions were based on non-ionic surfactants, namely pure tetraethyleneglycol monododecylether, ...
Precursor-directed biosynthesis of fluorinated iturin A in Bacillus spp.

Moran, Stephen ; Rai, Dilip K. ; Clark, Benjamin R. ; Murphy, Cormac D. (RSC Publishing, 2009)

Some iturin A-producing strains of Bacillus subtilis will elaborate the novel fluorinated analogue when incubated with 3-fluoro-L-tyrosine. The activity of iturin A is dependent on the D-tyrosine residue and the presence ...
Purification and properties of fluoroacetate dehalogenase from Pseudomonas fluorescens DSM 8341

Donnelly, Clár ; Murphy, Cormac D. (Springer, 2009)

The degradation of fluoroacetate by microorganisms has been established for some time, although only a handful of dehalogenases capable of hydrolyzing the stable C-F bond have been studied. The bacterium Pseudomonas ...
Rapid depletion of dissolved oxygen in 96 well microtitre plate Staphylococcus epidermidis biofilm assays promotes biofilm development and is influenced by inoculum cell concentration

Cotter, John J. ; O'Gara, James P. ; Casey, Eoin (Wiley, 2009-08-01)

Biofilm-related research using 96-well microtiter plates involves static incubation of plates indiscriminate of environmental conditions, making oxygen availability an important variable which has not been considered to ...
Study of translational, librational and intra-molecular motion of adsorbed liquid water monolayers at various TiO2 interfaces

Kavathekar, Ritwik S. ; English, Niall J. ; MacElroy, J. M. Don (Taylor and Francis, 2011-10-19)

Equilibrium classical molecular dynamics (MD) simulations have been performed to investigate the vibrational motion of water in contact with rutile-(110), rutile-(100), rutile-(001), anatase-(101) and anatase-(001) surfaces ...
Treatment of fluoroacetate by a Pseudomonas fluorescens biofilm grown in membrane aerated biofilm reactor

Heffernan, Barry ; Murphy, Cormac D. ; Syron, Eoin ; Casey, Eoin (ACS Publications, 2009)

Fluorinated organic compounds have widespread applications, and their accumulation in the environment is a concern. Biofilm reactors are an effective technology for the treatment of contaminated wastewater, yet almost no ...
