Anisotropy of excitation and relaxation of photogenerated charge carriers in graphene.

Nano letters

Mittendorff M, Winzer T, Malic E, Knorr A, Berger C, de Heer WA, Schneider H, Helm M, Winnerl S.
PMID: 24559191
Nano Lett. 2014 Mar 12;14(3):1504-7. doi: 10.1021/nl404730y. Epub 2014 Feb 24.

We present a pump-probe experiment on graphene, which reveals a pronounced dependence of the pump-induced transmission on the angle between pump and probe polarization. It reflects a strong anisotropy of the pump-induced occupation of photogenerated carriers in momentum space....

Improving the fatigue resistance of diarylethene switches.

Journal of the American Chemical Society

Herder M, Schmidt BM, Grubert L, Pätzel M, Schwarz J, Hecht S.
PMID: 25679768
J Am Chem Soc. 2015 Feb 25;137(7):2738-47. doi: 10.1021/ja513027s. Epub 2015 Feb 13.

When applying photochromic switches as functional units in light-responsive materials or devices, an often disregarded yet crucial property is their resistance to fatigue during photoisomerization. In the large family of diarylethene photoswitches, formation of an annulated isomer as a...

Visible-Light-Driven Water Oxidation by a Molecular Manganese Vanadium Oxide Cluster.

Angewandte Chemie (International ed. in English)

Schwarz B, Forster J, Goetz MK, Yücel D, Berger C, Jacob T, Streb C.
PMID: 27062440
Angew Chem Int Ed Engl. 2016 May 17;55(21):6329-33. doi: 10.1002/anie.201601799. Epub 2016 Apr 09.

Photosynthetic water oxidation in plants occurs at an inorganic calcium manganese oxo cluster, which is known as the oxygen evolving complex (OEC), in photosystem II. Herein, we report a synthetic OEC model based on a molecular manganese vanadium oxide...

Electronic cooling via interlayer Coulomb coupling in multilayer epitaxial graphene.

Nature communications

Mihnev MT, Tolsma JR, Divin CJ, Sun D, Asgari R, Polini M, Berger C, de Heer WA, MacDonald AH, Norris TB.
PMID: 26399955
Nat Commun. 2015 Sep 24;6:8105. doi: 10.1038/ncomms9105.

In van der Waals bonded or rotationally disordered multilayer stacks of two-dimensional (2D) materials, the electronic states remain tightly confined within individual 2D layers. As a result, electron-phonon interactions occur primarily within layers and interlayer electrical conductivities are low....

Four-Wave Mixing in Landau-Quantized Graphene.

Nano letters

König-Otto JC, Wang Y, Belyanin A, Berger C, de Heer WA, Orlita M, Pashkin A, Schneider H, Helm M, Winnerl S.
PMID: 28234493
Nano Lett. 2017 Apr 12;17(4):2184-2188. doi: 10.1021/acs.nanolett.6b04665. Epub 2017 Feb 28.

For Landau-quantized graphene, featuring an energy spectrum consisting of nonequidistant Landau levels, theory predicts a giant resonantly enhanced optical nonlinearity. We verify the nonlinearity in a time-integrated degenerate four-wave mixing (FWM) experiment in the mid-infrared spectral range, involving the...

Patterns and predictors of sitting time over ten years in a large population-based Canadian sample: Findings from the Canadian Multicentre Osteoporosis Study (CaMos).

Preventive medicine reports

PMID: 28180056
Prev Med Rep. 2017 Jan 24;5:289-294. doi: 10.1016/j.pmedr.2017.01.015. eCollection 2017 Mar.

Our objective was to describe patterns and predictors of sedentary behavior (sitting time) over 10 years among a large Canadian cohort. Data are from the Canadian Multicentre Osteoporosis Study, a prospective study of women and men randomly selected from...

Early Changes in Alpha Band Power and DMN BOLD Activity in Alzheimer's Disease: A Simultaneous Resting State EEG-fMRI Study.

Frontiers in aging neuroscience

Brueggen K, Fiala C, Berger C, Ochmann S, Babiloni C, Teipel SJ.
PMID: 29056904
Front Aging Neurosci. 2017 Oct 06;9:319. doi: 10.3389/fnagi.2017.00319. eCollection 2017.

Simultaneous resting state functional magnetic resonance imaging (rsfMRI)-resting state electroencephalography (rsEEG) studies in healthy adults showed robust positive associations of signal power in the alpha band with BOLD signal in the thalamus, and more heterogeneous associations in cortical default...

Persistence and recurrence of vesicoureteric reflux in children after endoscopic therapy - implications of a risk-adapted follow-up.

Central European journal of urology

Haid B, Berger C, Roesch J, Becker T, Koen M, Langsteger W, Oswald J.
PMID: 26568888
Cent European J Urol. 2015;68(3):389-95. doi: 10.5173/ceju.2015.560. Epub 2015 Aug 24.

INTRODUCTION: There is no well-defined follow-up scheme available to reliably detect persistent or recurrent vesicoureteric reflux (VUR) after endoscopic therapy (ET), but also to reduce postoperative invasive diagnostics in these children. Our aim was the evaluation of possible predictors...

Is the impairment in temporal allocation of visual attention in children with ADHD related to a developmental delay or a structural cognitive deficit?.

Research in developmental disabilities

PMID: 25462498
Res Dev Disabil. 2015 Jan;36:384-395. doi: 10.1016/j.ridd.2014.10.014. Epub 2014 Nov 08.

We investigated the temporal allocation of visual attention in 11-year-old children with attention-deficit/hyperactivity disorder (ADHD) by comparing their attentional blink (AB) parameters (duration, amplitude and minimum performance) with those observed in three groups of healthy control participants (8-year-olds, 11-year-olds...
