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 ...
Spray deposited NiOx films on ITO substrates as photoactive electrodes for p-type dye-sensitized solar cells

Awais, Muhammad ; Dowling, Denis P. ; Rahman, Mahfujur ; Vos, Johannes G. ; Decker, Franco ; Dini, Danilo (Springer, 2013-02)

Spray deposition followed by sintering of nickel oxide (NiO x ) nanoparticles (average diameter: 40 nm) has been chosen as method of deposition of mesoporous NiO x coatings onto indium tin oxide (ITO) substrates. This ...
Studies on the effect of concentration of a self-inhibitory substrate on biofilm reaction rate under co-diffusion and counter diffusion configurations

Syron, Eoin ; Kelly, Hugh ; Casey, Eoin (Elsevier, 2009-06-15)

A simple mathematical model was developed to investigate the utilization rate of a self-inhibitory substrate in idealised biofilm reactors operating with either counter-diffusion or co-diffusion of oxygen and phenol. This ...
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 ...
Synergistic effects of Bi/S codoping on visible light-activated anatase TiO2 photocatalysts from first principles

Long, Run ; English, Niall J. (ACS Publications, 2009-04-20)

The electronic properties and photocatalytic activity of S and/or Bi-doped anatase TiO2 are investigated by first-principles density functional theory calculations. For S-doped TiO2, S 3p states locate above the top of the ...
Synergistic effects on band gap-narrowing in titania by codoping from first-principles calculations

Long, Run ; English, Niall J. (ACS Publications, 2010-02-12)

The large intrinsic band gap in TiO2 has hindered severely its potential application for visible-light irradiation. In this study, we have used a passivated approach to modify the band edges of anatase-TiO2 by codoping of ...
A TD-DFT study of the effects of structural variations on the photochemistry of polyene dyes

Agrawal, Saurabh ; Dev, Pratibha ; English, Niall J. ; Thampi, Ravindranathan ; MacElroy, J. M. Don (RSC publications, 2011-10-06)

We report a TD-DFT study of three polyene dyes namely: NKX-2553, NKX-2554 and NKX-2569 in isolation as well as upon their adsorption on TiO2 nanoparticles. By choosing closely related dyes we wish to focus on the effects ...
A theoretical thermodynamic investigation of cascade reactions in dinuclear octa-azacryptates involving carbon dioxide

English, Niall J. ; Mooney, Damian A. (Springer, 2011)

This paper investigates the thermodynamics of gas-phase CO2 cascade uptake-reactions in the form of carbonate or methoxycarbonate anions in the host cavity of various dinuclear octa-azacryptates of m-CH2C6H4CH2 and ...
Tracer measurements reveal experimental evidence of biofilm consolidation

Casey, Eoin (Wiley, 2007-11-01)

The ability to simultaneously measure both biofilm thickness and the mass transfer coefficient of an inert tracer through it provides a powerful method to study biofilm development. In this communication previously published ...
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 ...
