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....

Management of cardiac arrest survivors in UK intensive care units: a survey of practice.

Journal of the Intensive Care Society

Ford AH, Clark T, Reynolds EC, Ross C, Shelley K, Simmonds L, Benger J, Soar J, Nolan JP, Thomas M.
PMID: 28979475
J Intensive Care Soc. 2016 May;17(2):117-121. doi: 10.1177/1751143715615151. Epub 2015 Nov 11.

BACKGROUND: Cardiac arrest is a common presentation to intensive care units. There is evidence that management protocols between hospitals differ and that this variation is mirrored in patient outcomes between institutions, with standardised treatment protocols improving outcomes within individual...

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...

Applying to college: Do information deficits lower the likelihood of college-eligible students from less-privileged families to pursue their college intentions?: Evidence from a field experiment.

Social science research

Ehlert M, Finger C, Rusconi A, Solga H.
PMID: 28888286
Soc Sci Res. 2017 Sep;67:193-212. doi: 10.1016/j.ssresearch.2017.04.005. Epub 2017 Apr 29.

Information deficits are considered an important source of why students from less-privileged families do not enroll in college, even when they are college-eligible and intend to go to college. In this paper, we examine whether correct and detailed information...

Shorter Exciton Lifetimes via an External Heavy-Atom Effect: Alleviating the Effects of Bimolecular Processes in Organic Light-Emitting Diodes.

Advanced materials (Deerfield Beach, Fla.)

Einzinger M, Zhu T, de Silva P, Belger C, Swager TM, Van Voorhis T, Baldo MA.
PMID: 28892200
Adv Mater. 2017 Oct;29(40). doi: 10.1002/adma.201701987. Epub 2017 Sep 11.

Multiexcited-state phenomena are believed to be the root cause of two exigent challenges in organic light-emitting diodes; namely, efficiency roll-off and degradation. The development of novel strategies to reduce exciton densities under heavy load is therefore highly desirable. Here,...

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

Gebel K, Pont S, Ding D, Bauman AE, Chau JY, Berger C, Prior JC.
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

Donnadieu S, Berger C, Lallier M, Marendaz C, Laurent A.
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...
