Autor: Mastropierro, Pasquale, Kennedy, Alan R., Hevia, Eva

Publikováno v: Mastropierro, Pasquale; Kennedy, Alan R.; Hevia, Eva (2022). Metallation of sensitive fluoroarenes using a potassium TMP-zincate supported by a silyl(bis)amido ligand. Chemical Communications, 58(34), pp. 5292-5295. Royal Society of Chemistry 10.1039/D2CC00979J

Combining a bulky bis(amide) and a reactive one-coordinate TMP (2,2,6,6-tetramethylpiperidide) ligand, a new mixed K/Zn heteroleptic base has been developed for regioselective zincation of fluoroarenes. This special ligand set allows for trapping and

Innovations in point-of-care electrochemical detection of Pyocyanin

Autor: Caitlin McLean, Kelly Brown, James Windmill, Lynn Dennany

Pseudomonas Aeruginosa (P. Aeruginosa) is a prevalent and opportunistic bacterium which frequently causes severe nosocomial infection. Current clinical detection methods are limited in terms of necessary time and equipment. Increasingly, P. Aeruginos

Peroxidase Activity of Myoglobin Variants Reconstituted with Artificial Cofactors

Autor: Chao Guo, Robert J. Chadwick, Adam Foulis, Giada Bedendi, Andriy Lubskyy, Kyle J. Rodriguez, Michela M. Pellizzoni, Ross D. Milton, Rebecca Beveridge, Nico Bruns

Publikováno v: ChemBioChem. 23

Myoglobin (Mb) can react with hydrogen peroxide (H 2O 2) to form a highly active intermediate compound and catalyse oxidation reactions. To enhance this activity, known as pseudo-peroxidase activity, previous studies have focused on the modification

Combining steady state and temperature jump IR spectroscopy to investigate the allosteric effects of ligand binding to dsDNA

Autor: Michael Towrie, Robby Fritzsch, Tom McLeish, Hedvika Toncrova, Neil T. Hunt, Jessica Dale, Ian P. Clark, Anthony W. Parker, C. Peter Howe, Gregory M. Greetham

Publikováno v: Physical Chemistry Chemical Physics. 23:15352-15363

Changes in the structural dynamics of double stranded (ds)DNA upon ligand binding have been linked to the mechanism of allostery without conformational change, but direct experimental evidence remains elusive. To address this, a combination of steady

Unraveling high-pressure gas storage mechanisms in shale nanopores through SANS

Autor: Shimin Liu, Guijie Sang, Long Fan, Rui Zhang, Tomasz Blach

Publikováno v: Environmental Science: Nano. 8:2706-2717

As storage rocks rather than source rocks, shale reservoirs can potentially serve as energy storehouses for energy security and sequester CO 2in the long term to mitigate climate change. Despite extensive studies investigating the geochemical and geo

A universal polymer shell-isolated nanoparticle (SHIN) design for single particle spectro-electrochemical SERS sensing using different core shapes

Autor: Delali K. Boccorh, Alastair W. Wark, Leonard Berlouis, Andrew J. Wain, Peter A. Macdonald, Colm W. Boyle

Publikováno v: Nanoscale Advances. 3:6415-6426

Shell-isolated nanoparticles (SHINs) have attracted increasing interest for non-interfering plasmonic enhanced sensing in fields such as materials science, biosensing, and in various electrochemical systems. The metallic core of these nanoparticles i

Alkene Syn- and Anti-Oxyamination with Malonoyl Peroxides

Autor: Nicholas C. O. Tomkinson, Jonathan M. Curle, Alan R. Kennedy, Marina C. Perieteanu, Philip G. Humphreys

Publikováno v: Organic Letters

Malonoyl peroxide [6] is an effective reagent for the syn- or anti-oxyamination of alkenes. Reaction of [6] and an alkene in the presence of O-tert-butyl-N-tosylcarbamate (R3 = CO2tBu) leads to the anti-oxyaminated product in up to 99% yield. Use of

Electro-osmotic and viscous effects upon pressure to drive a droplet through a capillary

Autor: Paul Grassia

A charged oil droplet advancing into a charged capillary is considered, assuming the special case in which charges are opposite and equal. The droplet is surrounded by an aqueous phase that wets the capillary wall, such that a thin film adjacent to t

Competitive gold/nickel transmetalation

Autor: Brady J. H. Austen, Mitchell J. Demchuk, David J. Nelson, Joseph A. Zurakowski, Marcus W. Drover

Transmetalation is a key method for the construction of element-element bonds. Here, we disclose the reactivity of [NiII(Ar)(I)(diphosphine)] compounds with arylgold(I) transmetalating agents, which is directly relevant to cross-coupling catalysis. B
