The Electrochemical Characterization of Single Core-Shell Nanoparticles.

Angewandte Chemie (International ed. in English)

Holt LR, Plowman BJ, Young NP, Tschulik K, Compton RG.
PMID: 26572689
Angew Chem Int Ed Engl. 2016 Jan 04;55(1):397-400. doi: 10.1002/anie.201509008. Epub 2015 Nov 17.

We report the direct solution-phase characterization of individual gold-core silver-shell nanoparticles through an electrochemical means, with selectivity achieved between the core and shell components based on their different redox activities. The electrochemically determined core-shell sizes are in excellent agreement...

Anionogenic mixed valency in KxBa1-xO2-δ.

Inorganic chemistry

Giriyapura S, Zhang B, de Groot RA, de Wijs GA, Caretta A, van Loosdrecht PH, Kockelmann W, Palstra TT, Blake GR.
PMID: 24328297
Inorg Chem. 2014 Jan 06;53(1):496-502. doi: 10.1021/ic402493q. Epub 2013 Dec 11.

We have synthesized members of an isostructural solid solution series KxBa1-xO2-δ (x < 0.41, δ < 0.11) containing mixed-valent dioxygen anions. Synthesis in liquid ammonia solution allows a continuous range of compounds to be prepared. X-ray and neutron diffraction...

The strong catalytic effect of Pb(II) on the oxygen reduction reaction on 5 nm gold nanoparticles.

Physical chemistry chemical physics : PCCP

Wang Y, Laborda E, Plowman BJ, Tschulik K, Ward KR, Palgrave RG, Damm C, Compton RG.
PMID: 24407350
Phys Chem Chem Phys. 2014 Feb 21;16(7):3200-8. doi: 10.1039/c3cp55306j.

Citrate-capped gold nanoparticles (AuNPs) of 5 nm in diameter are synthesized via wet chemistry and deposited on a glassy carbon electrode through electrophoresis. The kinetics of the oxygen reduction reaction (ORR) on the modified electrode is determined quantitatively in...

Total pancreatectomy and islet autotransplantation: A decade nationwide analysis.

World journal of transplantation

Fazlalizadeh R, Moghadamyeghaneh Z, Demirjian AN, Imagawa DK, Foster CE, Lakey JR, Stamos MJ, Ichii H.
PMID: 27011922
World J Transplant. 2016 Mar 24;6(1):233-8. doi: 10.5500/wjt.v6.i1.233.

AIM: To investigate outcomes and predictors of in-hospital morbidity and mortality after total pancreatectomy (TP) and islet autotransplantation.METHODS: The nationwide inpatient sample (NIS) database was used to identify patients who underwent TP and islet autotransplantation (IAT) between 2002-2012 in...

Structure and Abundance of Nitrous Oxide Complexes in Earth's Atmosphere.

The journal of physical chemistry. A

Salmon SR, de Lange KM, Lane JR.
PMID: 26983553
J Phys Chem A. 2016 Apr 07;120(13):2096-105. doi: 10.1021/acs.jpca.5b11853. Epub 2016 Mar 23.

We have investigated the lowest energy structures and binding energies of a series of atmospherically relevant nitrous oxide (N2O) complexes using explicitly correlated coupled cluster theory. Specifically, we have considered complexes with nitrogen (N2-N2O), oxygen (O2-N2O), argon (Ar-N2O), and...

Cavitation and bubble dynamics: the Kelvin impulse and its applications.

Interface focus

Blake JR, Leppinen DM, Wang Q.
PMID: 26442141
Interface Focus. 2015 Oct 06;5(5):20150017. doi: 10.1098/rsfs.2015.0017.

Cavitation and bubble dynamics have a wide range of practical applications in a range of disciplines, including hydraulic, mechanical and naval engineering, oil exploration, clinical medicine and sonochemistry. However, this paper focuses on how a fundamental concept, the Kelvin...

Assessing Systemic Stress in Otolaryngology: Methodology and Feasibility of Hair and Salivary Cortisol Testing.

Journal of nature and science

Genther DJ, Laudenslager ML, Sung YK, Blake CR, Chen DS, Lin FR.
PMID: 26436139
J Nat Sci. 2015 Aug;1(8).

OBJECTIVE: Elevated systemic stress is a predictor of adverse health outcomes, and stress can be objectively quantified by cortisol concentration. Despite its utility, such testing is rarely performed in otolaryngology. This manuscript provides details on the principles, methodology, and...

Capping agent promoted oxidation of gold nanoparticles: cetyl trimethylammonium bromide.

Physical chemistry chemical physics : PCCP

Plowman BJ, Tschulik K, Young NP, Compton RG.
PMID: 26382661
Phys Chem Chem Phys. 2015 Oct 21;17(39):26054-8. doi: 10.1039/c5cp05146k. Epub 2015 Sep 18.

Capping agents, key for nanoparticle stability, may hugely influence chemical behaviour. We show that differently capped gold nanoparticles, with either citrate or cetyl trimethylammonium bromide (CTAB) capping agents, show qualitatively different electron transfer properties. Specifically through cyclic voltammetry and...

Intramolecular Hydrogen Bonding in Substituted Aminoalcohols.

The journal of physical chemistry. A

Lane JR, Schrøder SD, Saunders GC, Kjaergaard HG.
PMID: 27447952
J Phys Chem A. 2016 Aug 18;120(32):6371-8. doi: 10.1021/acs.jpca.6b05898. Epub 2016 Aug 03.

The qualifying features of a hydrogen bond can be contentious, particularly where the hydrogen bond is due to a constrained intramolecular interaction. Indeed there is disagreement within the literature whether it is even possible for an intramolecular hydrogen bond...

Discovery of a potentially deleterious variant in TMEM87B in a patient with a hemizygous 2q13 microdeletion suggests a recessive condition characterized by congenital heart disease and restrictive cardiomyopathy.

Cold Spring Harbor molecular case studies

Yu HC, Coughlin CR, Geiger EA, Salvador BJ, Elias ER, Cavanaugh JL, Chatfield KC, Miyamoto SD, Shaikh TH.
PMID: 27148590
Cold Spring Harb Mol Case Stud. 2016 May;2(3):a000844. doi: 10.1101/mcs.a000844.

Restrictive cardiomyopathy (RCM) is a rare cause of heart muscle disease with the highest mortality rate among cardiomyopathy types. The etiology of RCM is poorly understood, although genetic causes have been implicated, and syndromic associations have been described. Here,...

Upper limit on the inner radiation belt MeV electron intensity.

Journal of geophysical research. Space physics

Li X, Selesnick RS, Baker DN, Jaynes AN, Kanekal SG, Schiller Q, Blum L, Fennell J, Blake JB.

No instruments in the inner radiation belt are immune from the unforgiving penetration of the highly energetic protons (tens of MeV to GeV). The inner belt proton flux level, however, is relatively stable; thus, for any given instrument, the...

Isotope fractionation and atmospheric oxygen: implications for phanerozoic O(2) evolution.

Science. 2000 Mar 03;287(5458):1630-3. doi: 10.1126/science.287.5458.1630.

Models describing the evolution of the partial pressure of atmospheric oxygen over Phanerozoic time are constrained by the mass balances required between the inputs and outputs of carbon and sulfur to the oceans. This constraint has limited the applicability...
