A variety of phosphated zeolite H-ZSM-5 samples are investigated by using a combination of Fourier transfer infrared (FTIR) spectroscopy, single pulse (27)Al, (29)Si, (31)P, (1)H-(31)P cross polarization (CP), (27)Al-(31)P CP, and (27)Al 3Q magic angle spinning nuclear magnetic resonance...

Prevalence Rates of Major Depressive Disorders: The Effects of Varying the Diagnostic Criteria in an Older Primary Care Population.

The American journal of geriatric psychiatry : official journal of the American Association for Geriatric Psychiatry

Hendrie HC, Callahan CM, Levitt EE, Hui SL, Mustek B, Austrom MG, Numberger JI, Tierney WM.
PMID: 28531015
Am J Geriatr Psychiatry. 1995 Spring;3(2):119-131. doi: 10.1097/00019442-199500320-00004. Epub 2012 Aug 08.

Patients age 60 years and older (N = 3,767) were screened for depression using the Center for Epidemiological Studies Depression Scale (CES-D). A random sample of patients scoring ≥ 16 on the CES-D (n = 44) and of patients...

NMR assignments of a di-pentacyclo-undecane cyclic ether.

Magnetic resonance in chemistry : MRC

Kruger HG, Ramdhani R.
PMID: 16941577
Magn Reson Chem. 2006 Nov;44(11):1058-62. doi: 10.1002/mrc.1889.

The X-ray structure of a di-pentacyclo-undecane cyclic ether was recently reported. As part of a programme to use NMR spectroscopy for the structure elucidation of cage compounds, the complete NMR assignments of the cyclic ether was attempted. Major overlap...

Active control of slow light on a chip with photonic crystal waveguides.

Nature

Vlasov YA, O'Boyle M, Hamann HF, McNab SJ.
PMID: 16267549
Nature. 2005 Nov 03;438(7064):65-9. doi: 10.1038/nature04210.

It is known that light can be slowed down in dispersive materials near resonances. Dramatic reduction of the light group velocity-and even bringing light pulses to a complete halt-has been demonstrated recently in various atomic and solid state systems,...

Charge shift and triplet state formation in the 9-mesityl-10-methylacridinium cation.

Journal of the American Chemical Society

Benniston AC, Harriman A, Li P, Rostron JP, van Ramesdonk HJ, Groeneveld MM, Zhang H, Verhoeven JW.
PMID: 16287292
J Am Chem Soc. 2005 Nov 23;127(46):16054-64. doi: 10.1021/ja052967e.

The target donor-acceptor compound forms an acridinium-like, locally excited (LE) singlet state on illumination with blue or near-UV light. This LE state undergoes rapid charge transfer from the acridinium ion to the orthogonally sited mesityl group in polar solution....

Individual single-walled carbon nanotubes as nanoelectrodes for electrochemistry.

Nano letters

Heller I, Kong J, Heering HA, Williams KA, Lemay SG, Dekker C.
PMID: 15792427
Nano Lett. 2005 Jan;5(1):137-42. doi: 10.1021/nl048200m.

We demonstrate the use of individual single-walled carbon nanotubes (SWNTs) as nanoelectrodes for electrochemistry. SWNTs were contacted by nanolithography, and cyclic voltammetry was performed in aqueous solutions. Interestingly, metallic and semiconducting SWNTs yielded similar steady-state voltammetric curves. We clarify...

Control of Hamiltonian chaos as a possible tool to control anomalous transport in fusion plasmas.

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

Ciraolo G, Briolle F, Chandre C, Floriani E, Lima R, Vittot M, Pettini M, Figarella C, Ghendrih P.
PMID: 15244910
Phys Rev E Stat Nonlin Soft Matter Phys. 2004 May;69(5):056213. doi: 10.1103/PhysRevE.69.056213. Epub 2004 May 18.

It is shown that a relevant control of Hamiltonian chaos is possible through suitable small perturbations whose form can be explicitly computed. In particular, it is possible to control (reduce) the chaotic diffusion in the phase space of a...

(1S,3S)-Methyl 2-benzyl-6,7-dimeth-oxy-1-phenyl-1,2,3,4-tetra-hydro-isoquinoline-3-carboxyl-ate.

Acta crystallographica. Section E, Structure reports online

Naicker T, Govender T, Kruger HG, Maguire GE.
PMID: 21754788
Acta Crystallogr Sect E Struct Rep Online. 2011 Jun 01;67:o1403. doi: 10.1107/S1600536811017430. Epub 2011 May 14.

In the title compound, C(26)H(27)NO(4), the heterocyclic ring assumes a half-chair conformation and inter-molecular C-H⋯O inter-actions help to construct the three-dimensional network within the crystal packing.

Acta crystallographica. Section E, Structure reports online

Onajole OK, Govender T, Kruger HG, Maguire GE.
PMID: 21754821

Interplay between gyrokinetic turbulence, flows, and collisions: perspectives on transport and poloidal rotation.

Physical review letters

Dif-Pradalier G, Grandgirard V, Sarazin Y, Garbet X, Ghendrih P.
PMID: 19792575
Phys Rev Lett. 2009 Aug 07;103(6):065002. doi: 10.1103/PhysRevLett.103.065002. Epub 2009 Aug 04.

The impact of ion-ion collisions on confinement is investigated with the full-f and global gyrokinetic Gysela code through a series of nonlinear turbulence simulations for tokamak parameters. A twofold scan in the turbulence drive and in collisionality is performed,...
