Band gap anomalies of the (ZnM2O4)-O-III (M-III = Co, Rh, Ir) spinels
(2011)Development of high figure-of-merit p-type transparent conducting oxides has become a global research goal. ZnM 2 IIIO 4 (M III = Co, Rh, Ir) spinels have been identified as potential p-type materials, with ZnIr 2O 4 ... -
Band gap engineering of In2O3 by alloying with Tl2O3
(2013)Efficient modulation of the bandgap of In 2 O 3 will open up a route to improved electronic properties. We demonstrate using ab initio calculations that Tl incorporation into In 2 O 3 reduces the band gap and ... -
Benzylic Oligothioethers as Ditopic Ligands for Group 6 Transition Metal Carbonyls
(2000)The co-ordination preferences of a family of novel thioethers based on (alkylsulfanylmethyl)benzene were examined. The alkyl chain length and the number and position of the thioether substituents were varied. The ligands ... -
Bidentate N-Heterocyclic carbene complexes of group 13 trihydrides and trihalides.
(2002)top Treatment of the potentially chelating bis-carbene, 1,2-ethylene-3,3′-di-tert-butyl-diimidazole-2,2′-diylidene, EtIBut, with [MH3(NMe3)], M = Al, Ga, In, in a 1 ∶ 1 or 1 ∶ 2 stoichiometery led to good yields of the ... -
Bioinspired electro-permeable glycans on carbon: Fouling control for sensing in complex matrices
(2020)The effect of glycan adlayers on the electrochemical response of glassy carbon electrodes was studied using standard redox probes and complex aqueous matrices. Aryldiazonium cations of aryl-lactoside precursors were used ... -
Bioinspired Water Oxidation Using a Mn-Oxo Cluster Stabilized by Non-Innocent Organic Tyrosine Y161 and Plastoquinone Mimics
(2020)The complexity and energy demand of the H2O oxidation half-reaction represents the bottleneck for the development of sustainable, environmentally friendly H2 economies using H2O as energy feedstock. In Nature, photosynthetic ... -
Biological investigations of novel 1,8-naphthalimide compounds and the design and synthesis of pyridine based polyamides
(Trinity College (Dublin, Ireland). School of Chemistry, 2009)This thesis entitled "Biological Investigations of Novel 1,8-Naphthalimide Compounds and the Design and Synthesis of Pyridine Polyamides" is divided into six chapters. Chapter 1, the introduction focuses on the basic ... -
Bioremediation of unresolved complex mixtures in marine oil spills : an analytical perspective
(Trinity College (Dublin, Ireland). School of Chemistry, 2000)Unresolved complex mixture (UCM) is the fraction of some petroleums that cannot be resolved by conventional gas chromatography and is characteristic of biodegraded petroleum oils and some refined products such as lubricating ... -
Bipyridyl alkynyl-based polyphenylenes : tuning photoluminescence in metal-organic chromophores
(Trinity College (Dublin, Ireland). School of Chemistry, 2011)Chapter 1 introduces two series of novel polyphenylene molecules with inherent ligand functionality. These are prepared via a sequence of Sonogashira cross-coupling reactions and [2+4] Diels-Alder cycloadditions and are ... -
BODIPY-Pyrene and Perylene Dyads as Heavy-Atom-Free Singlet Oxygen Sensitizer
(2018)Dyads combining BODIPY as an electron acceptor and pyrene or perylene as electron donor subunits were prepared and their photophysical properties were studied by steady‐state and transient spectroscopy. Depending on the ... -
Boride cluster fusion via an M4-unit (M=Cu, Ag): molecular structure of [PPN][{Ru4H(CO)12B}2Cu4(m-Cl)][Cl]
(1992)The reaction of [ppn][Ru4H(CO)12BH] with [Cu(MeCN)4][BF4] in the presence of [ppn][Cl] yields [ppn][{Ru4H(CO)12B}2-Cu4(?-Cl)][Cl], which has been structurally characterised; the introduction of silver in place of copper ...
