Analysis of hydrocarbon bearing fluid inclusions HCFI) using time-resolved fluorescence spectroscopy
(Society of Photo-optical Instrumentation Engineers, 2005)Hydrocarbon-bearing fluid inclusions (HCFI) are microscopic cavities within rocks that are filled with petroleum oil, the composition of which may not have changed since the trapping event. Thus, the composition of that ... -
Anisotropy resolved multidimensional emission spectroscopy (ARMES): A new tool for protein analysis
(Elsevier, 2015-07-30)Structural analysis of proteins using the emission of intrinsic fluorophores is complicated by spectral overlap. Anisotropy resolved multidimensional emission spectroscopy (ARMES) overcame the overlap problem by the use ... -
Assessing the predictions of a NOx kinetic mechanism on recent hydrogen and syngas experimental data
(Elsevier, 2017-05-02)A detailed chemical kinetic mechanism has been developed to describe the pyrolysis and oxidation of the hydrogen/NOx and syngas/NOx systems. The thermodynamic data of nitrogenous compounds have been updated based on the ... -
Autoignition of ethanol in a rapid compression machine
(Elsevier, 2013-12-09)Ethanol is a renewable source of energy and significant attention has been directed to the development of a validated chemical kinetic mechanism for this fuel. The experimental data for the autoignition of ethanol in the ... -
Bi- to tetravalent glycoclusters presenting GlcNAc/GalNAc as inhibitors: from plant agglutinins to human macrophage galactose-type lectin (CD301) and galectins
(Royal Society of Chemistry, 2015-02-17)Emerging insights into the functional spectrum of tissue lectins leads to identification of new targets for the custom-made design of potent inhibitors, providing a challenge for synthetic chemistry. The affinity and ... -
Bodipy-ruthenium(II) tris-bipyridyl dyads for homogeneous photochemical oxidations
(Elsevier, 2014-10-28)Two Bodipy-ruthenium(II) tris-bipyridyl dyads were synthesized for use as sensitizers in photochemical oxidation reactions of organic substrates. The synthetic strategy involved the use of a simple ‘click’ CuAAC reaction ... -
Chain transfer to solvent in the radical polymerization of structurally diverse acrylamide monomers using straight-chain and branched alcohols as solvents
(Royal Society of Chemistry, 2014-01-02)Chain transfer to solvent in conventional radical polymerizations of N-tert-butylacrylamide (TBAM) and N-(2-morpholin-4-ylethyl) acrylamide (MEA) in a range of alcohol solvents is investigated. Mayo analysis of polymerization ... -
