Degradation Mechanisms of Magnesium Metal Anodes in Electrolytes Based on (CF.

Langmuir : the ACS journal of surfaces and colloids

Yoo HD, Han SD, Bolotin IL, Nolis GM, Bayliss RD, Burrell AK, Vaughey JT, Cabana J.
PMID: 28636826
Langmuir. 2017 Sep 19;33(37):9398-9406. doi: 10.1021/acs.langmuir.7b01051. Epub 2017 Jul 05.

The energy density of rechargeable batteries utilizing metals as anodes surpasses that of Li ion batteries, which employ carbon instead. Among possible metals, magnesium represents a potential alternative to the conventional choice, lithium, in terms of storage density, safety,...

Nazarov reactions intercepted by (4 + 3) cycloadditions with oxygen-substituted dienes.

The Journal of organic chemistry

LeFort FM, Mishra V, Dexter GD, Morgan TD, Burnell DJ.
PMID: 25984922
J Org Chem. 2015 Jun 05;80(11):5877-86. doi: 10.1021/acs.joc.5b00914. Epub 2015 May 22.

The oxyallyl cation intermediate from the Lewis acid mediated Nazarov reaction of an allenyl vinyl ketone was intercepted by acyclic, 2-silyloxy-substituted butadienes by highly regioselective (4 + 3) cycloadditions. Stereoselectivity was often modest, but in some instances steric interactions...

Torquoselectivity in the Nazarov reactions of allenyl vinyl ketones.

The Journal of organic chemistry

Morgan TD, LeBlanc LM, Ardagh GH, Boyd RJ, Burnell DJ.
PMID: 25521250
J Org Chem. 2015 Jan 16;80(2):1042-51. doi: 10.1021/jo502532a. Epub 2015 Jan 05.

Nazarov reactions mediated by BF3-etherate of a series of carbon-substituted allenyl vinyl ketones provided intermediates in which substituents on the termini of the allenes had rotated away from the vinyl moieties, and these intermediates were trapped by (4 +...

Expanding the phenotypic associations of globular glial tau subtypes.

Alzheimers Dement (Amst). 2016 Apr 08;4:6-13. doi: 10.1016/j.dadm.2016.03.006. eCollection 2016.

INTRODUCTION: Clinicopathologic correlation in non-Alzheimer's tauopathies is variable, despite refinement of pathologic diagnostic criteria. In the present study, the clinical and neuroimaging characteristics of globular glial tauopathy (GGT) were examined to determine whether subtyping according to consensus guidelines improves...

Origin of Electrochemical, Structural, and Transport Properties in Nonaqueous Zinc Electrolytes.

ACS applied materials & interfaces

Han SD, Rajput NN, Qu X, Pan B, He M, Ferrandon MS, Liao C, Persson KA, Burrell AK.
PMID: 26765789
ACS Appl Mater Interfaces. 2016 Feb 10;8(5):3021-31. doi: 10.1021/acsami.5b10024. Epub 2016 Jan 29.

Through coupled experimental analysis and computational techniques, we uncover the origin of anodic stability for a range of nonaqueous zinc electrolytes. By examination of electrochemical, structural, and transport properties of nonaqueous zinc electrolytes with varying concentrations, it is demonstrated...

A Lewis acid-free and phenolate-based magnesium electrolyte for rechargeable magnesium batteries.

Chemical communications (Cambridge, England)

Pan B, Zhang J, Huang J, Vaughey JT, Zhang L, Han SD, Burrell AK, Zhang Z, Liao C.
PMID: 25758092
Chem Commun (Camb). 2015 Apr 11;51(28):6214-7. doi: 10.1039/c5cc01225b.

A novel Lewis acid-free and phenolate-based magnesium electrolyte has been established. The excellent reversibility and stability of this electrolyte in battery cycling render this novel Lewis acid-free synthetic approach as a highly promising alternative for the development of highly...

Investigations of H-mode plasmas triggered directly by pellet injection in the DIII-D tokamak.

Physical review letters

Gohil P, Baylor LR, Jernigan TC, Burrell KH, Carlstrom TN.
PMID: 11177902
Phys Rev Lett. 2001 Jan 22;86(4):644-7. doi: 10.1103/PhysRevLett.86.644.

The transition from low-confinement (L-mode) to high-confinement (H-mode) plasmas has been directly produced by injecting frozen deuterium pellets in the DIII-D tokamak. H-mode transitions were produced at edge electron and ion temperatures below the L-mode values. This implies that...

Quiescent double barrier regime in the DIII-D tokamak.

Physical review letters

Greenfield CM, Burrell KH, DeBoo JC, Doyle EJ, Stallard BW, Synakowski EJ, Fenzi C, Gohil P, Groebner RJ, Lao LL, Makowski MA, McKee GR, Moyer RA, Rettig CL, Rhodes TL, Pinsker RI, Staebler GM, West WP.
PMID: 11384279
Phys Rev Lett. 2001 May 14;86(20):4544-7. doi: 10.1103/PhysRevLett.86.4544.

A new sustained high-performance regime, combining discrete edge and core transport barriers, has been discovered in the DIII-D tokamak. Edge localized modes (ELMs) are replaced by a steady oscillation that increases edge particle transport, thereby allowing particle control with...

7-Bromoquinolin-8-ol.

Acta crystallographica. Section C, Crystal structure communications

Collis GE, Burrell AK, John KD, Plieger PG.
PMID: 12909773
Acta Crystallogr C. 2003 Aug;59:o443-4. doi: 10.1107/s0108270103013714. Epub 2003 Jul 22.

Structure analysis of the title compound, C(9)H(6)BrNO, has established that bromination of an 8-hydroxyquinoline derivative occurred in the 7-position. Intermolecular and weak intramolecular O-H.N hydrogen bonds are present, the former causing the molecules to pack as hydrogen-bonded dimers in...

Cysteinyl-tRNA Synthetase from Astragalus Species.

Plant physiology

Burnell JN.
PMID: 16660863
Plant Physiol. 1979 Jun;63(6):1095-7. doi: 10.1104/pp.63.6.1095.

l-Cysteinyl-tRNA synthetases (EC 6.1.1.16) from four Astragalus species were partially purified. The substrate specificities of the cysteinyl-tRNA synthetase from three selenium accumulator species (A. crotalariae, A bisulcatus, and A. racemosus) were compared with those from two nonaccumulator species (A....
