Measuring couplings in crowded NMR spectra: pure shift NMR with multiplet analysis.

Chemical communications (Cambridge, England)

Foroozandeh M, Adams RW, Kiraly P, Nilsson M, Morris GA.
PMID: 26343867
Chem Commun (Camb). 2015 Oct 28;51(84):15410-3. doi: 10.1039/c5cc06293d.

The PSYCHE method for pure shift NMR is exploited to generate 2D J spectra with full decoupling in one dimension and multiplet structure in the other, allowing spin-spin coupling constants to be measured even in very crowded spectra. Significant...

Matrix-assisted diffusion-ordered spectroscopy: choosing a matrix.

Magnetic resonance in chemistry : MRC

Gramosa NV, Ricardo NMSP, Adams RW, Morris GA, Nilsson M.
PMID: 27272403
Magn Reson Chem. 2016 Oct;54(10):815-820. doi: 10.1002/mrc.4459. Epub 2016 Jun 07.

Diffusion-ordered spectroscopy (DOSY) is an important technique for separating the NMR signals of the components in a mixture, and relies on differences in diffusion coefficient. Standard DOSY experiments therefore struggle when the components of a mixture are of similar...

One-dimensional DOSY.

Journal of magnetic resonance (San Diego, Calif. : 1997)

Loening NM, Keeler J, Morris GA.
PMID: 11700086
J Magn Reson. 2001 Nov;153(1):103-12. doi: 10.1006/jmre.2001.2423.

A new NMR experiment for correlating diffusion coefficients and chemical shifts is presented. This experiment provides the same information as the conventional DOSY experiment, but only requires a single dimension because a nonuniform magnetic field gradient is used to...

Lung transplantation for cystic fibrosis; the effect of B cepacia genomovars on post transplant outcomes.

The Journal of heart and lung transplantation : the official publication of the International Society for Heart Transplantation

Characteristic temperatures and electron number densities in an R.F. capacitively coupled plasma.

Analytical and bioanalytical chemistry

Anghel SD, Frentiu T, Darvasi E, Rusu AM, Simon A, Cordos EA.
PMID: 15045375
Anal Bioanal Chem. 1996 Jun;355(3):250-1. doi: 10.1007/s0021663550250.

The excitation temperatures of Ar and Fe, the ionization temperatures of Ar and Ca and the electron number densities have been determined for a radiofrequency capacitively coupled plasma in the tip-ring electrode geometry. The temperatures and the electron number...

Analytical characterisation of a capacitively coupled plasma torch with a central tube electrode.

Talanta

Cordos EA, Frentiu T, Rusu AM, Angel SD, Fodor A, Ponta M.
PMID: 18967525
Talanta. 1999 Apr;48(4):827-37. doi: 10.1016/s0039-9140(98)00099-x.

A new type of radiofrequency capacitively coupled plasma torch is presented. The torch electrode geometry is coaxial with a tubular central electrode and one or two outer ring electrodes. The argon plasma is generated at 275 W radiofrequency power...

Ganymede: observations by radar.

Science (New York, N.Y.)

Goldstein RM, Morris GA.
PMID: 17818164
Science. 1975 Jun 20;188(4194):1211-2. doi: 10.1126/science.188.4194.1211.

Radar cross-section measurements indicate that Ganymede scatters to Earth 12 percent of the power expected from a conducting sphere of the same size and distance. This compares with 8 percent for Mars, 12 percent for Venus, 6 percent for...

Model of dispersive transport across sharp interfaces between porous materials.

Physical review. E, Statistical, nonlinear, and soft matter physics

Cortis A, Zoia A.
PMID: 19658668
Phys Rev E Stat Nonlin Soft Matter Phys. 2009 Jul;80(1):011122. doi: 10.1103/PhysRevE.80.011122. Epub 2009 Jul 17.

Recent laboratory experiments on solute migration in composite porous columns have shown an asymmetry in the solute arrival time upon reversal of the flow direction, which is not explained by current paradigms of transport. In this work, we propose...

Matrix-assisted diffusion-ordered spectroscopy: mixture resolution by NMR using SDS micelles.

Magnetic resonance in chemistry : MRC

Tormena CF, Evans R, Haiber S, Nilsson M, Morris GA.
PMID: 20540075
Magn Reson Chem. 2010 Jul;48(7):550-3. doi: 10.1002/mrc.2621.

Diffusion-ordered spectroscopy (DOSY) is a powerful technique for mixture analysis, but in its basic form it cannot separate the component spectra for species with very similar diffusion coefficients. It has been recently demonstrated that the component spectra of a...

Spin echo NMR spectra without J modulation.

Chemical communications (Cambridge, England)

Aguilar JA, Nilsson M, Bodenhausen G, Morris GA.
PMID: 22143456
Chem Commun (Camb). 2012 Jan 21;48(6):811-3. doi: 10.1039/c1cc16699a. Epub 2011 Dec 05.

The spin echo is the single most important building block in modern NMR spectroscopy, but echo modulation by scalar couplings J can severely complicate its use. We show for the first time that a general but unacknowledged solution to...

Targeted Antibiotic Prophylaxis for Lung Transplantation in Cystic Fibrosis Patients Colonised with Pseudomonas aeruginosa Using Multiple Combination Bactericidal Testing.

Journal of transplantation

Haja Mydin H, Corris PA, Nicholson A, Perry JD, Meachery G, Marrs EC, Peart S, Fagan C, Lordan JL, Fisher AJ, Gould FK.
PMID: 22848792
J Transplant. 2012;2012:135738. doi: 10.1155/2012/135738. Epub 2012 Jul 16.

Early infection is a recognised complication after lung transplantation in patients with cystic fibrosis (CF). Our centre uses multiple combination bactericidal testing (MCBT) when determining appropriate peritransplant prophylactic regimens. To evaluate our strategy, we compared the incidence of posttransplant...
