Additive tuning redox potential in metallacarboranes by sequencial halogen substitution
(Wiley, 2010-04-21)The first artificially made set of electron acceptors is presented that are derived from a unique platform Cs[3,3′-Co(C2B9H11)2], for which the redox potential of each differs from its predecessor by a fixed amount. The ... -
Adsorption and conformations of lysozyme and α-lactalbumin at a water-octane interface
(AIP Publishing, 2017-11)As proteins contain both hydrophobic and hydrophilic amino acids, they will readily adsorb onto interfaces between water and hydrophobic fluids such as oil. This adsorption normally causes changes in the protein structure, ... -
Adsorption of the natural protein surfactant Rsn-2 onto liquid interfaces
(Royal Society of Chemistry, 2017-02-27)To stabilize foams, droplets, and films at liquid interfaces nature has evolved a range of protein biosurfactants. Compared to synthetic surfactants, these combine surface activity with biocompatibility and low solution ... -
Advances in rapid compression machine studies of low- and intermediate-temperature autoignition phenomena
(Elsevier, 2017-07-10)Rapid compression machines (RCMs) are widely used to acquire experimental insights into fuel autoignition and pollutant formation chemistry, especially at conditions relevant to current and future combustion technologies. ... -
Aggregation of nanoparticles on one and two-component bilayer membranes
(AIP Publishing, 2014)Using dissipative particle dynamics simulations the aggregation of nanoparticles on single and two-component bilayers is investigated. For a uniform bilayer the aggregation of nanoparticlesdepends strongly on the location ... -
The air-water interface stabilizes α-helical conformations of the insulin B-chain
(AIP Publishing, 2019-08-09)Adsorption of proteins onto liquid interfaces, such as the air-water interface, often leads to changes in the protein conformation. This can lead to changes in protein assembly behaviour, with aggregation and fibrillation ... -
The air-water interface stabilizes α-helical conformations of the insulin B-chain
(NUI Galway, 2019-09-16)Dataset to accompany article: Cheung, David L. (2019). The air-water interface stabilizes α-helical conformations of the insulin B-chain. The Journal of Chemical Physics, 151(6), 064706. doi: 10.1063/1.5100253 -
Allelopathic interactions between the brown algal genus lobophora (dictyotales, phaeophyceae) and scleractinian corals
(Nature Publishing Group, 2016-01-05)Allelopathy has been recently suggested as a mechanism by which macroalgae may outcompete corals in damaged reefs. Members of the brown algal genus Lobophora are commonly observed in close contact with scleractinian corals ... -
