Scaling up of continuous-flow, microwave-assisted, organic reactions by varying the size of Pd-functionalized catalytic monoliths.

Beilstein journal of organic chemistry

He P, Haswell SJ, Fletcher PD, Kelly SM, Mansfield A.
PMID: 21915220
Beilstein J Org Chem. 2011;7:1150-7. doi: 10.3762/bjoc.7.133. Epub 2011 Aug 23.

A product-scalable, catalytically mediated flow system has been developed to perform Suzuki-Miyaura reactions under a microwave heating regime, in which the volumetric throughput of a Pd-supported silica monolith can be used to increase the quantity of the product without...

Anomalous superfluid density in quantum critical superconductors.

Hashimoto K, Mizukami Y, Katsumata R, Shishido H, Yamashita M, Ikeda H, Matsuda Y, Schlueter JA, Fletcher JD, Carrington A, Gnida D, Kaczorowski D, Shibauchi T.
PMID: 23404698
Proc Natl Acad Sci U S A. 2013 Feb 26;110(9):3293-7. doi: 10.1073/pnas.1221976110. Epub 2013 Feb 12.

When a second-order magnetic phase transition is tuned to zero temperature by a nonthermal parameter, quantum fluctuations are critically enhanced, often leading to the emergence of unconventional superconductivity. In these "quantum critical" superconductors it has been widely reported that...

Higher Levels and Intensity of Physical Activity Are Associated with Reduced Mortality among Community Dwelling Older People.

Journal of aging research

Hrobonova E, Breeze E, Fletcher AE.
PMID: 21437004
J Aging Res. 2011 Mar 07;2011:651931. doi: 10.4061/2011/651931.

Introduction. There is limited evidence on physical activity and mortality in older people. Methods. People aged 75-84 years (n = 1449) participating in a randomized trial of health screening in UK general practice were interviewed about their physical activity...

Multiply scattered light tomography and confocal imaging: detecting neovascularization in age-related macular degeneration.

Optics express

Elsner A, Miura M, Burns S, Beausencourt E, Kunze C, Kelley L, Walker J, Wing G, Raskauskas P, Fletcher D, Zhou Q, Dreher A.
PMID: 19404374
Opt Express. 2000 Jul 17;7(2):95-106. doi: 10.1364/oe.7.000095.

A novel technique, Multiply Scattered Light Tomography (MSLT), and confocal Infrared Imaging are used to provide diagnostic information using a comfortable, rapid, and noninvasive method. We investigated these techniques in detecting neovascularization in age-related macular degeneration. The MSLT used...

Bond-forming reactions of small triply charged cations with neutral molecules.

Chemistry (Weinheim an der Bergstrasse, Germany)

Fletcher JD, Parkes MA, Price SD.
PMID: 23843367
Chemistry. 2013 Aug 12;19(33):10965-70. doi: 10.1002/chem.201301861. Epub 2013 Jul 10.

Time-of-flight mass spectrometry reveals that atomic and small molecular triply charged cations exhibit extensive bond-forming chemistry, following gas-phase collisions with neutral molecules. These experiments show that at collision energies of a few eV, I(3+) reacts with a variety of...

A simultaneous voltammetric temperature and humidity sensor.

The Analyst

Xiong L, Fletcher AM, Davies SG, Norman SE, Hardacre C, Compton RG.
PMID: 23001184
Analyst. 2012 Nov 07;137(21):4951-7. doi: 10.1039/c2an35939a. Epub 2012 Sep 24.

We report the simultaneous measurement of temperature and humidity by analysing square wave voltammetric responses of two ferrocene derivatives, decamethylferrocene (DmFc) and 1,2-diferrocenylethylene (bisferrocene, BisFc) in 1-(2-methoxyethyl)-1-methyl-pyrrolidinium tris(pentafluoroethyl)trifluorophosphate ([Moepyrr][FAP]). These two molecules produce three peaks in square wave voltammetry....

Medical Errors Cause Harm in Veterinary Hospitals.

Frontiers in veterinary science

Wallis J, Fletcher D, Bentley A, Ludders J.
PMID: 30805349
Front Vet Sci. 2019 Feb 05;6:12. doi: 10.3389/fvets.2019.00012. eCollection 2019.

Medical errors are a leading cause of mortality in human medicine. In contrast, errors in veterinary medicine are rarely discussed, and there is little known about their nature and frequency. This study aimed to evaluate the type and severity...
