Imaging of toll-like receptor microarrays was achieved using scanning electrochemical microscopy with the successful integration of two ferrocene derivatives in order to enhance the background contrast. This investigation has resulted in the novel fabrication of a tuneable, multiplex, broad-spectrum bacterial sensor for the interrogation of conserved microbial stimuli. © The Royal Society of Chemistry.

The Herschel ATLAS is the largest open-time key project that will be carried out on the Herschel Space Observatory. It will survey 570 deg 2 of the extragalactic sky, 4 times larger than all the other Herschel extragalactic surveys combined, in five far-infrared and submillimeter bands. We describe the survey, the complementary multiwavelength data sets that will be combined with the Herschel data, and the six major science programs we are undertaking. Using new models based on a previous submillimeter survey of galaxies, we present predictions of the properties of the ATLAS sources in other wave bands. © 2010.

We present the results of an optical spectroscopic study of two-dimensional atomic crystals of the high-temperature superconductor Bi2Sr2CaCu2O8+δ. Our measurements reveal a pronounced suppression of the optical conductivity σ1(ω) with thickness. Using an effective medium approximation, we interpret this in terms of an insulating surface layer. The surface layer explains the insulating behavior previously observed in exfoliated Bi2Sr2CaCu2O8+δ and has implications for future studies and potential applications of these materials. © 2014 American Physical Society.

Recently, main group reagents have attracted a lot of attention in bond-forming reactions in organic synthesis. This article highlights the use of pentafluorophenyl substituted boron reagents in their reactions with CC and CC π-bonds for the synthesis of heterocyclic and aromatic compounds. These cyclisation reactions fall into four general classes although there is some overlap between classes and often combinations of these different types of reactivity are observed in the formation of the final heterocyclic product: (i) 1,2- (and 1,4-) additions of nucleophile and Lewis-acidic boron centre, (ii) 1,1-carboboration, (iii) carbocation rearrangements and (iv) cycloaddition chemistry. In addition, the prospect of using such boron reagents catalytically in the synthesis of aromatic compounds such as oxazoles and dibenzopentalene derivatives is emphasised.

We report an intermolecular hydroacylation of allylic alcohols with salicylaldehydes to afford β-hydroxy aryl ketones in 73-94% yields as single regioisomers. The reactivity and regioselectivity were promoted by catalytic amounts of a phosphinite that forms a dynamic covalent bond with the allylic alcohol. Hydroacylation of 1,2- and 1,1-disubstituted olefins generates β-hydroxy aryl ketones bearing tertiary and quaternary centers, respectively. © 2012 The Royal Society of Chemistry.

Recently, main group reagents have attracted a lot of attention in bond-forming reactions in organic synthesis. This article highlights the use of pentafluorophenyl substituted boron reagents in their reactions with C=C and CC -bonds for the synthesis of heterocyclic and aromatic compounds. These cyclisation reactions fall into four general classes although there is some overlap between classes and often combinations of these different types of reactivity are observed in the formation of the final heterocyclic product: (i) 1,2- (and 1,4-) additions of nucleophile and Lewis-acidic boron centre, (ii) 1,1-carboboration, (iii) carbocation rearrangements and (iv) cycloaddition chemistry. In addition, the prospect of using such boron reagents catalytically in the synthesis of aromatic compounds such as oxazoles and dibenzopentalene derivatives is emphasised.
