Fendt LA, Stöhr M, Wintjes N, Enache M, Jung TA, Diederich F.
PMID: 19760724
Chemistry. 2009 Oct 26;15(42):11139-50. doi: 10.1002/chem.200901502.

The self-assembly properties of two Zn(II) porphyrin isomers on Cu(111) are studied at different coverage by means of scanning tunneling microscopy (STM). Both isomers are substituted in their meso-positions by two voluminous 3,5-di(tert-butyl)phenyl and two rod-like 4'-cyanobiphenyl groups, respectively....

Why a harmonic solution for lossless, perfectly homogeneous, left-handed material cannot exist.

Journal of the Optical Society of America. A, Optics, image science, and vision

Maystre D, Enoch S, McPhedran R.

J Opt Soc Am A Opt Image Sci Vis. 2008 Aug;25(8):1937-43. doi: 10.1364/josaa.25.001937.

In a preceding paper [J. Opt. Soc. Am. A21, 122 (2004)], we proposed proof of the nonexistence of harmonic solutions for a perfectly homogeneous left-handed material with both relative permittivity and relative permeability equal to -1 using the theorem...

Comparison of zwitterionic N-alkylaminomethanesulfonic acids to related compounds in the Good buffer series.

Several N-alkyl and N,N-dialkylaminomethanesulfonic acids were synthesized (as zwitterions and/or sodium salts) to be tested for utility as biological buffers at lower pH levels than existing Good buffer compounds (aminoalkanesulfonates with a minimum of two carbons between amine and...

Intrathecal baclofen therapy for spinal origin spasticity: spinal cord injury, spinal cord disease, and multiple sclerosis.

Neuromodulation : journal of the International Neuromodulation Society

Ochs G, Naumann C, Dimitrijevic M, Sindou M.
PMID: 22151114
Neuromodulation. 1999 Apr;2(2):108-19. doi: 10.1046/j.1525-1403.1999.00108.x.

Spasticity can affect individuals with spinal injury, spinal disease, or multiple sclerosis. In most cases, spasticity is useful because it helps compensate for motor deficits. Oral medication is ineffective or produces intolerable side effects in ≅ 30% of patients...

Chemistry (Weinheim an der Bergstrasse, Germany)

Matena M, Stöhr M, Riehm T, Björk J, Martens S, Dyer MS, Persson M, Lobo-Checa J, Müller K, Enache M, Wadepohl H, Zegenhagen J, Jung TA, Gade LH.
PMID: 20077537
Chemistry. 2010 Feb 15;16(7):2079-91. doi: 10.1002/chem.200902596.

The structural chemistry and reactivity of 1,3,8,10-tetraazaperopyrene (TAPP) on Cu(111) under ultra-high-vacuum (UHV) conditions has been studied by a combination of experimental techniques (scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy, XPS) and DFT calculations. Depending on the deposition...

Solvent-free oxidation of primary carbon-hydrogen bonds in toluene using Au-Pd alloy nanoparticles.

Science (New York, N.Y.)

Kesavan L, Tiruvalam R, Ab Rahim MH, bin Saiman MI, Enache DI, Jenkins RL, Dimitratos N, Lopez-Sanchez JA, Taylor SH, Knight DW, Kiely CJ, Hutchings GJ.
