Long-term effects of physical exercise on verbal learning and memory in middle-aged adults: results of a one-year follow-up study.

Brain sciences

Hötting K, Schauenburg G, Röder B.
PMID: 24961197
Brain Sci. 2012 Aug 27;2(3):332-46. doi: 10.3390/brainsci2030332.

A few months of physical exercise have been shown to increase cognition and to modulate brain functions in previously sedentary, mainly older adults. However, whether the preservation of newly gained cognitive capacities requires an active maintenance of the achieved...

Reversible Photoswitching of a Spin-Crossover Molecular Complex in the Solid State at Room Temperature.

Angewandte Chemie (International ed. in English)

Rösner B, Milek M, Witt A, Gobaut B, Torelli P, Fink RH, Khusniyarov MM.
PMID: 26480333
Angew Chem Int Ed Engl. 2015 Oct 26;54(44):12976-80. doi: 10.1002/anie.201504192. Epub 2015 Sep 07.

Spin-crossover metal complexes are highly promising magnetic molecular switches for prospective molecule-based devices. The spin-crossover molecular photoswitches developed so far operate either at very low temperatures or in the liquid phase, which hinders practical applications. Herein, we present a...

Ultramicroscopy. 2016 May;164:70-7. doi: 10.1016/j.ultramic.2015.12.007. Epub 2016 Feb 11.

We demonstrate a prototype of a Focused Ion Beam machine based on the ionization of a laser-cooled cesium beam and adapted for imaging and modifying different surfaces in the few-tens nanometer range. Efficient atomic ionization is obtained by laser...

Schmidt O, Rothhardt J, Röser F, Linke S, Schreiber T, Rademaker K, Limpert J, Ermeneux S, Yvernault P, Salin F, Tünnermann A.
PMID: 17546185
Opt Lett. 2007 Jun 01;32(11):1551-3. doi: 10.1364/ol.32.001551.

We report on a Q-switched short-length fiber laser producing 100 W of average output power at 100 kHz repetition rate and pulse durations as short as 17 ns. Up to 2 mJ of energy and sub-10-ns pulse duration are...

High-power picosecond fiber amplifier based on nonlinear spectral compression.

Optics letters

Limpert J, Deguil-Robin N, Manek-Hönninger I, Salin F, Schreiber T, Liem A, Röser E, Zellmer H, Tünnermann A, Courjaud A, Hönninger C, Mottay E.
PMID: 15832915
Opt Lett. 2005 Apr 01;30(7):714-6. doi: 10.1364/ol.30.000714.

We report on the rare-earth-doped fiber-based generation of nearly transform-limited 10-ps pulses based on self-phase-modulation-induced spectral compression. An ytterbium-doped low nonlinearity photonic crystal fiber is used as a gain medium. An average power of as much as 97 W...

Electron transfer in oligothiophene-bridged bisporphyrins.

The journal of physical chemistry. B

Regehly M, Wang T, Siggel U, Fuhrhop JH, Röder B.
PMID: 19191508
J Phys Chem B. 2009 Feb 26;113(8):2526-34. doi: 10.1021/jp808052u.

Oligothiophene-bridged zinc-tin bisporphyrinates were synthesized. Their absorption spectra have been analyzed in terms of exciton interaction and porphyrin-bridge coupling by through-bond interaction and the steady-state fluorescence spectra in terms of differential Stokes shifts for the electron-donating zinc and the...

Visual target selection and motor planning define attentional enhancement at perceptual processing stages.

Frontiers in human neuroscience

Collins T, Heed T, Röder B.
PMID: 20224662
Front Hum Neurosci. 2010 Mar 05;4:14. doi: 10.3389/neuro.09.014.2010. eCollection 2010.

Extracting information from the visual field can be achieved by covertly orienting attention to different regions, or by making saccades to bring areas of interest onto the fovea. While much research has shown a link between covert attention and...

Disorganized behavior on Link's cube test is sensitive to right hemispheric frontal lobe damage in stroke patients.

Frontiers in human neuroscience

Kopp B, Rösser N, Tabeling S, Stürenburg HJ, de Haan B, Karnath HO, Wessel K.

Front Hum Neurosci. 2014 Feb 17;8:79. doi: 10.3389/fnhum.2014.00079. eCollection 2014.

One of Luria's favorite neuropsychological tasks for challenging frontal lobe functions was Link's cube test (LCT). The LCT is a cube construction task in which the subject must assemble 27 small cubes into one large cube in such a...

Dispersion and characterization of arc discharge single-walled carbon nanotubes--towards conducting transparent films.

Nanoscale

Nanoscale. 2014 Apr 07;6(7):3695-703. doi: 10.1039/c3nr05788g.

This study addresses a combination of a well-developed and mild dispersion method and high-quality arc discharge single-walled carbon nanotubes (SWCNTs) as starting materials. Thus, we advance in fabrication of transparent, conducting films with extraordinary low material loss during SWCNT...
