One-dimensional PtO2 at Pt steps: formation and reaction with CO.

Physical review letters

Wang JG, Li WX, Borg M, Gustafson J, Mikkelsen A, Pedersen TM, Lundgren E, Weissenrieder J, Klikovits J, Schmid M, Hammer B, Andersen JN.
PMID: 16384475
Phys Rev Lett. 2005 Dec 16;95(25):256102. doi: 10.1103/PhysRevLett.95.256102. Epub 2005 Dec 15.

Using core-level spectroscopy and density functional theory we show that a one-dimensional (1D) oxide structure forms at the steps of the Pt(332) surface after exposure. The 1D oxide is found to be stable in an oxygen pressure range, where...

Extended one-dimensional supramolecular assembly on a stepped surface.

Physical review letters

Schnadt J, Rauls E, Xu W, Vang RT, Knudsen J, Laegsgaard E, Li Z, Hammer B, Besenbacher F.
PMID: 18352306
Phys Rev Lett. 2008 Feb 01;100(4):046103. doi: 10.1103/PhysRevLett.100.046103. Epub 2008 Jan 30.

2,6-naphthalene-dicarboxylic acid was adsorbed on a Ag110 surface with an average terrace width of only some tens of a nm. Scanning tunneling microscopy shows that the adsorbates self-assemble into one-dimensional mesoscale length chains. These extend over several hundred nanometers...

Concept and application of a computational vaccinology workflow.

Immunome research

Söllner J, Heinzel A, Summer G, Fechete R, Stipkovits L, Szathmary S, Mayer B.
PMID: 21067549
Immunome Res. 2010 Nov 03;6:S7. doi: 10.1186/1745-7580-6-S2-S7.

BACKGROUND: The last years have seen a renaissance of the vaccine area, driven by clinical needs in infectious diseases but also chronic diseases such as cancer and autoimmune disorders. Equally important are technological improvements involving nano-scale delivery platforms as...

The ACT heroin trial: intellectual, practical and political challenges.

Drug and alcohol review

Drug Alcohol Rev. 1997 Sep;16(3):287-96. doi: 10.1080/09595239800187471.

An array of intellectual, practical and political challenges will be faced both if the Australian Capital Territory "heroin trial" does or does not eventuate. The intellectual challenges include the development of new methodologies and analytical tools for some of...

In vivo monitoring of splenocytes in NMRI nu/nu- and nu/+,- mice during Lewis lung tumor progression or regression.

International journal of oncology

Splenocytes of T-cell deficient NMRI nu/nu- mice (n=15) and of inbred immunocompetent NMRI nu/+,littermates (n=18) significantly (p

Observation of all the intermediate steps of a chemical reaction on an oxide surface by scanning tunneling microscopy.

ACS nano

Matthiesen J, Wendt S, Hansen JØ, Madsen GK, Lira E, Galliker P, Vestergaard EK, Schaub R, Laegsgaard E, Hammer B, Besenbacher F.
PMID: 19309169
ACS Nano. 2009 Mar 24;3(3):517-26. doi: 10.1021/nn8008245.

By means of high-resolution scanning tunneling microscopy (STM), we have revealed unprecedented details about the intermediate steps for a surface-catalyzed reaction. Specifically, we studied the oxidation of H adatoms by O(2) molecules on the rutile TiO(2)(110) surface. O(2) adsorbs...

An Aggressive Hypoxia Related Subpopulation of Melanoma Cells is TRP-2 Negative.

Translational oncology

Lenggenhager D, Curioni-Fontecedro A, Storz M, Shakhova O, Sommer L, Widmer DS, Seifert B, Moch H, Dummer R, Mihic-Probst D.
PMID: 24746711
Transl Oncol. 2014 Apr;7(2):206-12. doi: 10.1016/j.tranon.2014.02.018. Epub 2014 Apr 17.

Despite existing vaccination strategies targeting TRP-2, its function is not yet fully understood. TRP-2 is an enzyme involved in melanin biosynthesis and therefore discussed as a differentiation antigen. However, in mice Trp-2 was shown to be expressed in melanocyte...

A surface coordination network based on copper adatom trimers.

Surface coordination networks formed by co-adsorption of metal atoms and organic ligands have interesting properties, for example regarding catalysis and data storage. Surface coordination networks studied to date have typically been based on single metal atom centers. The formation...

Self-consistent determination of the spike-train power spectrum in a neural network with sparse connectivity.
