Nano electrospray combined with a quadrupole ion trap for the analysis of peptides and protein digests.

Journal of the American Society for Mass Spectrometry

Körner R, Wilm M, Morand K, Schubert M, Mann M.
PMID: 24203235
J Am Soc Mass Spectrom. 1996 Feb;7(2):150-6. doi: 10.1016/1044-0305(95)00626-5.

A nano electrospray (NanoES)/ion trap combination was developed to take advantage of the long spraying time of the NanoES source (Wilm, M. S., Mann, M. Int. J. Mass Spectrom. Ion Processes 1994, 136, 167-180) for extensive experiments on the...

Viscoelastic properties and efficient acoustic damping in confined polymer nano-layers at GHz frequencies.

Scientific reports

Hettich M, Jacob K, Ristow O, Schubert M, Bruchhausen A, Gusev V, Dekorsy T.
PMID: 27633351
Sci Rep. 2016 Sep 16;6:33471. doi: 10.1038/srep33471.

We investigate the viscoelastic properties of confined molecular nano-layers by time resolved optical pump-probe measurements. Access to the elastic properties is provided by the damping time of acoustic eigenmodes of thin metal films deposited on the molecular nano-layers which...

Distinguishing crystallization stages and their influence on quantum efficiency during perovskite solar cell formation in real-time.

Scientific reports

Wagner L, Mundt LE, Mathiazhagan G, Mundus M, Schubert MC, Mastroianni S, Würfel U, Hinsch A, Glunz SW.
PMID: 29097712
Sci Rep. 2017 Nov 02;7(1):14899. doi: 10.1038/s41598-017-13855-6.

Relating crystallization of the absorber layer in a perovskite solar cell (PSC) to the device performance is a key challenge for the process development and in-depth understanding of these types of high efficient solar cells. A novel approach that...

1.024 Tb/s wavelength conversion in a silicon waveguide with reverse-biased p-i-n junction.

Optics express

Sackey I, Gajda A, Peczek A, Liebig E, Zimmermann L, Petermann K, Schubert C.
PMID: 29041528
Opt Express. 2017 Sep 04;25(18):21229-21240. doi: 10.1364/OE.25.021229.

We experimentally show an all-optical wavelength conversion of 8 × 32-GBd single-polarization 16QAM signals using a silicon nano-rib waveguide. The application of reverse biasing of the p-i-n junction of the waveguide allows a conversion efficiency of -8.5 dB with...

A subset of patients with oral squamous cell carcinoma (OSCC), the most common subtype of head and neck squamous cell carcinoma (HNSCC), harbor dysplastic lesions (often visually identified as leukoplakia) prior to cancer diagnosis. Although evidence suggest that leukoplakia...

Glass-Based Transparent Conductive Electrode: Its Application to Visible-to-Ultraviolet Light-Emitting Diodes.

ACS applied materials & interfaces

Lee TH, Kim KH, Lee BR, Park JH, Schubert EF, Kim TG.
PMID: 27990816
ACS Appl Mater Interfaces. 2016 Dec 28;8(51):35668-35677. doi: 10.1021/acsami.6b12767. Epub 2016 Dec 19.

Nitride-based ultraviolet light-emitting diodes (UV LEDs) are promising replacements for conventional UV lamps. However, the external quantum efficiency of UV LEDs is much lower than for visible LEDs due to light absorption in the p-GaN contact and electrode layers,...

Comparative analyses of olfactory systems in terrestrial crabs (Brachyura): evidence for aerial olfaction?.

PeerJ

Krieger J, Braun P, Rivera NT, Schubart CD, Müller CH, Harzsch S.
PMID: 26713228
PeerJ. 2015 Dec 22;3:e1433. doi: 10.7717/peerj.1433. eCollection 2015.

Adaptations to a terrestrial lifestyle occurred convergently multiple times during the evolution of the arthropods. This holds also true for the "true crabs" (Brachyura), a taxon that includes several lineages that invaded land independently. During an evolutionary transition from...

Cavity-enhanced optical Hall effect in two-dimensional free charge carrier gases detected at terahertz frequencies.

Optics letters

Knight S, Schöche S, Darakchieva V, Kühne P, Carlin JF, Grandjean N, Herzinger CM, Schubert M, Hofmann T.

The effect of a tunable, externally coupled Fabry-Perot cavity to resonantly enhance the optical Hall effect signatures at terahertz frequencies produced by a traditional Drude-like two-dimensional electron gas is shown and discussed in this Letter. As a result, the...

Measuring the interactions between engineered nanoparticles and natural substrates (e.g. soils and sediments) has been very challenging due to highly heterogeneous and rough natural surfaces. In this study, three-dimensional nanostructured slanted columnar thin films (SCTFs), with well-defined roughness height...
