Conformations of myoglobin-derived peptides at the air-water interface
(American Chemical Society, 2016-04-14)The conformational change exhibited by proteins at liquid interfaces, such as the air-water and oil-water interfaces, has long been of interest, both for understanding protein structure outside of native environments and ... -
A connection between star formation activity and cosmic rays in the starburst galaxy M 82
(2009)Although Galactic cosmic rays (protons and nuclei) are widely believed to be dominantly accelerated by the winds and supernovae of massive stars, definitive evidence of this origin remains elusive nearly a century after ... -
Continuous culture of Escherichia coli, under selective pressure by a novel antimicrobial complex, does not result in development of resistance
(Nature Research, 2019-02-20)We attempted to generate de novo resistance to a newly described biocidal complex, ITC (iodo-thiocyanate complex), and to levofloxacin (LVX) in Escherichia coli ATCC 25922, by means of selective chemostat culture. We ... -
Contrasting responses to nutrient enrichment of prokaryotic communities collected from deep sea sites in the Southern Ocean
(MDPI Open-Access Journals, 2013-09-13)Abstract: Deep water samples (ca. 4,200 m) were taken from two hydrologically-similar sites around the Crozet islands with highly contrasting surface water productivities. Site M5 was characteristic of high productivity ... -
Control of transfer and weak closure in fusion systems
(2010)We show that K¿ and K¿ control transfer in every fusion system on a finite p-group when p ¿ 5, and that they control weak closure of elements in every fusion system on a finite p-group when p ¿ 3. This generalizes resultsof ... -
Controlling the pirouetting motion in rotaxanes by counterion exchange
(American Chemical Society, 2014-07-25)A fine control of the pirouetting motion of rotaxanes was achieved by using a series of metallabisdicarbollides. The latter were used as anions in the protonated form of benzylic amide macrocycle-containing fumaramide ... -
A convenient synthetic route to useful monobranched polyethoxylated halogen terminated [3,3 -Co(1,2-C2B9H11)2]- synthons
(Royal Society of Chemistry, 2009-11-15)An atom efficient and environmentally friendly route has been developed to obtain a new range of reagents in metallacarborane chemistry having monobranched polyethoxylated cobaltabisdicarbollide synthons. -
Conversion of gel-forming crystal needles to easily processable more equant crystals Using high-shear ultralow attrition agitation: accelerated Ostwald ripening without crystal attrition
(American Chemical Society, 2019-02-01)We demonstrate the first examples of the transformation of gel-forming crystal needles into easily processable more equant crystals by accelerated Ostwald ripening without detectable crystal attrition. Using high solution ... -
Cost-effective wireless microcontroller for internet connectivity of open-source chemical devices
(American Chemical Society, 2018-06-04)This paper presents a system for remote monitoring of turbidity data that can detect light intensity and temperature using a microcontroller and the Internet of Things. The system comprises a light dependent resistor and ... -
Creep, recovery, and waves in a nonlinear fiber-reinforced viscoelastic solid
(Society for Industrial and Applied Mathematics, 2007-10-10)We present a constitutive model capturing some of the experimentally observed features of soft biological tissues: nonlinear viscoelasticity, nonlinear elastic anisotropy, and nonlinear viscous anisotropy. For this model ... -
Critical evaluation of thermochemical properties of C-1-C-4 species: updated group-contributions to estimate thermochemical properties
(AIP Publishing, 2015-01-05)A review of literature on enthalpies of formation and molar entropies for alkanes, alkenes, alcohols, hydroperoxides, and their associated radicals has been compiled and critically evaluated. By comparing literature values, ... -
Cross platform standardisation of an experimental pipeline for use in the identification of dysregulated human circulating MiRNAs
(Public Library of Science, 2015-09-10)Micro RNAs (miRNAs) are a class of highly conserved small non-coding RNAs that play an important part in the post-transcriptional regulation of gene expression. A substantial number of miRNAs have been proposed as biomarkers ... -
Crystalline adducts of the Lawsone molecule (2-hydroxy-1,4-naphthaquinone): optical properties and computational modelling
(Royal Society of Chemistry, 2015-09-04)Four new crystalline adducts of the Lawsone molecule (2-hydroxy-1,4-naphthaquinone) with 4,4'-bipyridine, 4-(2-pyridine-4-ethyl)pyridine, 1,3-di.4-pyridyl)propane and 2-hydroxy pyridine are reported. Adduct formation leads ... -
Crystallization of organic salts from the gas phase: When does proton transfer take place?
(American Chemical Society, 2020-12-13)Salt formation with proton transfer is observed in crystals grown by cosublimation of the salt coformers. Diflunisal salts were obtained with 4-[3-(pyridin-4-yl)propyl]pyridine, piperazine, and 4-dimethylaminopyridine. ... -
