Ideal contribution to the macroscopic quasiequilibrium entropy of anisotropic fluids.

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

Ilg P, Hütter M, Kröger M.
PMID: 21797393
Phys Rev E Stat Nonlin Soft Matter Phys. 2011 Jun;83(6):061713. doi: 10.1103/PhysRevE.83.061713. Epub 2011 Jun 29.

The Landau-de Gennes free energy plays a central role in the macroscopic theory of anisotropic fluids. Here, the ideal, entropic contribution to this free energy-that is always present in these systems, irrespectively of the detailed form of interactions or...

Dementia and amputation.

Interventional medicine & applied science

Schuch V, Moysidis T, Weiland D, Santosa F, Kröger K.
PMID: 24265873
Interv Med Appl Sci. 2012 Dec;4(4):175-80. doi: 10.1556/IMAS.4.2012.4.1. Epub 2012 Dec 27.

OBJECTIVES: To our experience dementia seems to play an increasing role for major amputation in patients suffering from peripheral arterial disease (PAD). To confirm our impression, we analysed the rate of dementia associated with different surgical procedures using the...

Non-polymeric asymmetric binary glass-formers. II. Secondary relaxation studied by dielectric, .

The Journal of chemical physics

Pötzschner B, Mohamed F, Bächer C, Wagner E, Lichtinger A, Bock D, Kreger K, Schmidt HW, Rössler EA.
PMID: 28456197
J Chem Phys. 2017 Apr 28;146(16):164504. doi: 10.1063/1.4980085.

We investigate the secondary (β-) relaxations of an asymmetric binary glass former consisting of a spirobichroman derivative (SBC; T

Semiconductor-Metal Nanofloret Hybrid Structures by Self-Processing Synthesis.

Journal of the American Chemical Society

Hazut O, Waichman S, Subramani T, Sarkar D, Dash S, Roncal-Herrero T, Kröger R, Yerushalmi R.
PMID: 26972888
J Am Chem Soc. 2016 Mar 30;138(12):4079-86. doi: 10.1021/jacs.5b12667. Epub 2016 Mar 21.

We present a synthetic strategy that takes advantage of the inherent asymmetry exhibited by semiconductor nanowires prepared by Au-catalyzed chemical vapor deposition (CVD). The metal-semiconductor junction is used for activating etch, deposition, and modification steps localized to the tip...

Depopulation of Single-Phthalocyanine Molecular Orbitals upon Pyrrolic-Hydrogen Abstraction on Graphene.

ACS nano

Néel N, Lattelais M, Bocquet ML, Kröger J.
PMID: 26812093
ACS Nano. 2016 Feb 23;10(2):2010-6. doi: 10.1021/acsnano.5b06153. Epub 2016 Feb 01.

Single-molecule chemistry with a scanning tunneling microscope has preponderantly been performed on metal surfaces. The molecule-metal hybridization, however, is often detrimental to genuine molecular properties and obscures their changes upon chemical reactions. We used graphene on Ir(111) to reduce...

A Vacuum Ultraviolet Absorption Array Spectrometer as a Selective Detector for Comprehensive Two-Dimensional Gas Chromatography: Concept and First Results.

Analytical chemistry

Gröger T, Gruber B, Harrison D, Saraji-Bozorgzad M, Mthembu M, Sutherland A, Zimmermann R.
PMID: 26810390
Anal Chem. 2016 Mar 15;88(6):3031-9. doi: 10.1021/acs.analchem.5b02472. Epub 2016 Feb 26.

Fast and selective detectors are very interesting for comprehensive two-dimensional gas chromatography (GC × GC). This is particularly true if the detector system can provide additional spectroscopic information on the compound structure and/or functionality. Other than mass spectrometry (MS),...

Retrospective life course data from European countries on how early life experiences determine health in old age and possible mid-life mediators.

Data in brief

Pakpahan E, Hoffmann R, Kröger H.
PMID: 27995163
Data Brief. 2016 Dec 07;10:277-282. doi: 10.1016/j.dib.2016.11.094. eCollection 2017 Feb.

The data presented in this article is related to the research paper entitled "The long arm of childhood circumstances on health in old age: Evidence from SHARELIFE" (E. Pakpahan, R. Hoffmann, H. Kröger, 2016) [1]. It presents the distribution...

Surface-enhanced mid-infrared spectroscopy using a quantum cascade laser.

Optics express

Hasenkampf A, Kröger N, Schönhals A, Petrich W, Pucci A.
PMID: 25836797
Opt Express. 2015 Mar 09;23(5):5670-80. doi: 10.1364/OE.23.005670.

We report on the successful measurement of surface-enhanced infrared vibrational spectra from a few nanometer thick organic semiconductor layers on samples with resonant plasmonic nanoantennas arranged in arrays. For the first time, a setup with a tunable quantum cascade...
