Synchrotron-based valence shell photoionization of CH radical.

The Journal of chemical physics

Gans B, Holzmeier F, Krüger J, Falvo C, Röder A, Lopes A, Garcia GA, Fittschen C, Loison JC, Alcaraz C.
PMID: 27250306
J Chem Phys. 2016 May 28;144(20):204307. doi: 10.1063/1.4950880.

We report the first experimental observations of X(+) (1)Σ(+)←X (2)Π and a(+) (3)Π←X (2)Π single-photon ionization transitions of the CH radical performed on the DESIRS beamline at the SOLEIL synchrotron facility. The radical was produced by successive hydrogen-atom abstractions...

Competition and cooperation in a synchronous bushcricket chorus.

Royal Society open science

Hartbauer M, Haitzinger L, Kainz M, Römer H.
PMID: 26064537
R Soc Open Sci. 2014 Oct 08;1(2):140167. doi: 10.1098/rsos.140167. eCollection 2014 Oct.

Synchronous signalling within choruses of the same species either emerges from cooperation or competition. In our study on the katydid Mecopoda elongata, we aim to identify mechanisms driving evolution towards synchrony. The increase of signal amplitude owing to synchronous...

Hierarchical Manipulation of Block Copolymer Patterns on 3D Topographic Substrates: Beyond Graphoepitaxy.

Advanced materials (Deerfield Beach, Fla.)

Park S, Cheng X, Böker A, Tsarkova L.
PMID: 27270877
Adv Mater. 2016 Aug;28(32):6900-5. doi: 10.1002/adma.201601098. Epub 2016 Jun 06.

Templates of complex nanopatterns in a form of hierarchically sequenced dots and stripes can be generated in block copolymer films on lithography-free 3D topographic substrates. The approach exploits thickness- and swelling-responsive morphological behavior of block copolymers, and demonstrates novel...

Wetting Phenomena on (Gradient) Wrinkle Substrates.

Langmuir : the ACS journal of surfaces and colloids

Hiltl S, Böker A.
PMID: 27517879
Langmuir. 2016 Sep 06;32(35):8882-8. doi: 10.1021/acs.langmuir.6b02364. Epub 2016 Aug 24.

We characterize the wetting behavior of nanostructured wrinkle and gradient wrinkle substrates. Different contact angles on both sides of a water droplet after deposition on a gradient sample induce the self-propelled motion of the liquid toward smaller wrinkle dimensions....

A core-shell structured BaTiO3 precursor preparation, characterization and potential.

Analytical and bioanalytical chemistry

Rössel M, Gablenz S, Müller T, Röder A, Abicht HP.
PMID: 12560979
Anal Bioanal Chem. 2003 Jan;375(2):310-4. doi: 10.1007/s00216-002-1669-0. Epub 2002 Dec 19.

A new procedure for the preparation of a core-shell-structured BaTiO(3) precursor (core=TiO(2); shell=BaCO(3)) will be described. The structure of this precursor is characterized by electron microscopy (environmental scanning electron microscopy; energy disperse X-ray spectroscopy), whereas the development of phases...

Amphiphilic Janus micelles with polystyrene and poly(methacrylic acid) hemispheres.

Journal of the American Chemical Society

Erhardt R, Zhang M, Böker A, Zettl H, Abetz C, Frederik P, Krausch G, Abetz V, Müller AH.
PMID: 12630881
J Am Chem Soc. 2003 Mar 19;125(11):3260-7. doi: 10.1021/ja028982q.

We describe the synthesis and the solution properties of Janus micelles containing a polybutadiene (PB) core and a compartmentalized corona consisting of a poly(methacrylic acid) (PMAA) and a polystyrene (PS) hemisphere. The Janus micelles were obtained via cross-linking the...

Direct comparison between potential landscape and local density of states in a disordered two-dimensional electron system.

Physical review letters

Morgenstern M, Klijn J, Meyer C, Getzlaff M, Adelung R, Römer RA, Rossnagel K, Kipp L, Skibowski M, Wiesendanger R.
PMID: 12225050
Phys Rev Lett. 2002 Sep 23;89(13):136806. doi: 10.1103/PhysRevLett.89.136806. Epub 2002 Sep 09.

The local density of states (LDOS) of the adsorbate-induced two-dimensional electron system (2DES) on n-InAs(110) is studied by scanning tunneling spectroscopy. In contrast to a similar 3DES, the 2DES LDOS exhibits 20 times stronger corrugations and rather irregular structures....

BACKGROUND: Pichia stipitis xylose reductase (Ps-XR) has been used to design Saccharomyces cerevisiae strains that are able to ferment xylose. One example is the industrial S. cerevisiae xylose-consuming strain TMB3400, which was constructed by expression of P. stipitis xylose...

Spin noise spectroscopy in GaAs (110) quantum wells: access to intrinsic spin lifetimes and equilibrium electron dynamics.

Physical review letters

Müller GM, Römer M, Schuh D, Wegscheider W, Hübner J, Oestreich M.

In this Letter, the first spin noise spectroscopy measurements in semiconductor systems of reduced effective dimensionality are reported. The nondemolition measurement technique gives access to the otherwise concealed intrinsic, low temperature electron spin relaxation time of n-doped GaAs (110)...
