An ignition delay time and chemical kinetic modeling study of the pentane isomers
(Elsevier, 2016-10-26)Ignition delay times of n-pentane, iso-pentane, and neo-pentane mixtures were measured in two shock tubes and in a rapid compression machine. The experimental data were used as validation targets for the model described ... -
Impact of pig slurry amendments on phosphorus, suspended sediment and metal losses in laboratory runoff boxes under simulated rainfall
(Elsevier, 2012)Losses of phosphorus (P) when pig slurry applications to land are followed by a rainfall event or losses from soils with high P contents can contribute to eutrophication of receiving waters. The addition of amendments to ... -
Influence of chemical composition on the fluorescence lifetimes of crude petroleum oils
(Society of Photo-optical Instrumentation Engineers, 2003)Fluorescence based methods are increasingly being used for the analysis of crude oils because they offer high speed, low cost, non-contact, and non-destructive testing options. The fluorescence of crude oils is due to the ... -
Inhibition of Burkholderia multivorans Adhesion to Lung Epithelial Cells by Bivalent Lactosides
(MDPI, 2012-08-24)Burkholderia cepacia complex (Bcc) is an opportunistic pathogen in cystic fibrosis patients which is inherently resistant to antimicrobial agents. The mechanisms of attachment and pathogenesis of Bcc, a group of 17 species, ... -
Interaction of nanoparticles with ideal liquid-liquid interfaces
(2009)Using molecular simulations the interaction between a noncharged nanoparticle and an ideal liquid-liquid interface is studied. The free energy profile as function of nanoparticle-interface separation is determined using ... -
Investigating the solid state hosting abilities of homo- and hetero-valent [Co-7] metallocalix[6]arenes
(RSC, 2012)A family of homo-valent [Co(II)(7)(OH)(6)(L-1)(6)](NO3)(2)(1), [(MeOH)(2)subset of Co(II)(7)(OH)(6)(L-1)(6)](NO3)(2) (2) (where L1H = 2-iminomethyl-6-methoxyphenol) and hetero-valent [(NO3)(2)subset of Co(III)Co(II)(6)(O ... -
Investigating tryptophan quenching of fluorescein fluorescence under protolytic equilibrium
(2009)Fluorescein is one of most used fluorescent labels for characterizing biological systems, such as proteins, and is used in fluorescence microscopy. However, if fluorescein is to be used for quantitative measurements involving ... -
Kernel principal component analysis residual diagnosis (KPCARD): an automated method to remove cosmic ray artefacts in Raman spectra.
(2016)A new, fully automated, rapid method, referred to as kernel principal component analysis residual diagnosis (KPCARD), is proposed for removing cosmic ray artifacts (CRAs) in Raman spectra, and in particular for large Raman ... -
Lectins: getting familiar with translators of the sugar code
(MDPI, 2015-01-22)The view on the significance of the presence of glycans in glycoconjugates is undergoing a paradigmatic change. Initially mostly considered to be rather inert and passive, the concept of the sugar code identifies glycans ... -
Lewis acid induced anomerization of se-glycosides. Application to synthesis of alpha-Se-GalCer
(American Chemical Society, 2016-01-22)The TiCl4 induced anomerization of selenium glycosides of galacturonic acid derivatives is reported. The reaction was successful for galacturonic acid when various alkyl, alkenyl, alkynyl, saccharide, steroid, and lipid ... -
Light driven styrene epoxidation and hydrogen generation using H2O as an oxygen source in a photoelectrosynthesis cell
(Royal Society of Chemistry, 2015-10-02)A dye-sensitized photoelectrosynthesis cell (DSPEC) has been prepared for the oxidation of alkenes to epoxides and evolution of hydrogen using water as an oxygen source and sunlight. A Ru oxidation catalyst, 2,2+ , is ... -
Liquid-crystal-mediated force between a cylindrical nanoparticle and substrate
(American Physical Society, 2007-10-25)Using classical density functional theory, the structure of a molecular fluid around a cylindrical nanoparticle near a solid substrate is studied. The solvent-mediated force between the nanoparticle and the substrate is ... -
Low Temperature Fluorescence Studies of Crude Petroleum Oils
(2011)We have studied the low-temperature (133-298 K) fluorescence emission of crude petroleum oils using a combination of steady-state and time-resolved measurements. This was done, first, to see if we could generate linear ... -
Low-content quantification in powders using Raman spectroscopy: a facile chemometric approach to sub 0.1% limits of detection.
(American Chemical Society, 2015-02-23)A robust and accurate analytical methodology for low-content (<0.1%) quantification in the solid-state using Raman spectroscopy, sub-sampling, and chemometrics was demonstrated using a piracetam–proline model. The method ... -
