New insights into colloidal gold flakes: structural investigation, micro-ellipsometry and thinning procedure towards ultrathin monocrystalline layers.

Nanoscale

Hoffmann B, Bashouti MY, Feichtner T, Mačković M, Dieker C, Salaheldin AM, Richter P, Gordan OD, Zahn DR, Spiecker E, Christiansen S.
PMID: 26661036
Nanoscale. 2016 Feb 28;8(8):4529-36. doi: 10.1039/c5nr04439a.

High-quality fabrication of plasmonic devices often relies on wet-chemically grown ultraflat, presumably single-crystalline gold flakes due to their superior materials properties. However, important details about their intrinsic structure and their optical properties are not well understood yet. In this...

Electrochemical in situ investigations of SEI and dendrite formation on the lithium metal anode.

Bieker G, Winter M, Bieker P.
PMID: 25735488
Phys Chem Chem Phys. 2015 Apr 14;17(14):8670-9. doi: 10.1039/c4cp05865h. Epub 2015 Mar 04.

This comparative work studies the self-enforcing heterogeneity of lithium deposition and dissolution as the cause for dendrite formation on the lithium metal anode in various liquid organic solvent based electrolytes. In addition, the ongoing lithium corrosion, its rate and...

Wetting-induced effective interaction potential between spherical particles.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Bauer C, Bieker T, Dietrich S.
PMID: 11089094
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000 Oct;62(4):5324-38. doi: 10.1103/physreve.62.5324.

Using a density-functional-based interface displacement model, we determine the effective interaction potential between two spherical particles which are immersed in a homogeneous fluid such as the vapor phase of a one-component substance or the A-rich liquid phase of a...

Efficient multi-keV underdense laser-produced plasma radiators.

Physical review letters

Back CA, Grun J, Decker C, Suter LJ, Davis J, Landen OL, Wallace R, Hsing WW, Laming JM, Feldman U, Miller MC, Wuest C.
PMID: 11800887
Phys Rev Lett. 2001 Dec 31;87(27):275003. doi: 10.1103/PhysRevLett.87.275003. Epub 2001 Dec 12.

Novel, efficient x-ray sources have been created by supersonically heating a large volume of Xe gas. A laser-induced bleaching wave quickly ionizes the high- Z gas, and the resulting plasma emits x rays. This method significantly improves the production...

Nanopore tomography of a laser focus.

Nano letters

Keyser UF, Krapf D, Koeleman BN, Smeets RM, Dekker NH, Dekker C.
PMID: 16277463
Nano Lett. 2005 Nov;5(11):2253-6. doi: 10.1021/nl051597p.

We demonstrate that the ionic current through a solid-state nanopore can be used to measure at single nanometer resolution the three-dimensional intensity profile of a laser directly in the focus of a microscope objective. We find a linear dependence...

Electrical generation and absorption of phonons in carbon nanotubes.

Nature

Leroy BJ, Lemay SG, Kong J, Dekker C.
PMID: 15549099
Nature. 2004 Nov 18;432(7015):371-4. doi: 10.1038/nature03046.

The interplay between discrete vibrational and electronic degrees of freedom directly influences the chemical and physical properties of molecular systems. This coupling is typically studied through optical methods such as fluorescence, absorption and Raman spectroscopy. Molecular electronic devices provide...

Individual single-walled carbon nanotubes as nanoelectrodes for electrochemistry.

Nano letters

Heller I, Kong J, Heering HA, Williams KA, Lemay SG, Dekker C.
PMID: 15792427
Nano Lett. 2005 Jan;5(1):137-42. doi: 10.1021/nl048200m.

We demonstrate the use of individual single-walled carbon nanotubes (SWNTs) as nanoelectrodes for electrochemistry. SWNTs were contacted by nanolithography, and cyclic voltammetry was performed in aqueous solutions. Interestingly, metallic and semiconducting SWNTs yielded similar steady-state voltammetric curves. We clarify...

Implementing an innovative consent form: the PREDICT experience.

Implementation science : IS

Decker C, Arnold SV, Olabiyi O, Ahmad H, Gialde E, Luark J, Riggs L, DeJaynes T, Soto GE, Spertus JA.
PMID: 19117513
Implement Sci. 2008 Dec 31;3:58. doi: 10.1186/1748-5908-3-58.

BACKGROUND: In the setting of coronary angiography, generic consent forms permit highly variable communication between patients and physicians. Even with the existence of multiple risk models, clinicians have been unable to readily access them and thus provide patients with...

Voids, nanochannels and formation of nanotubes with mobile Sn fillings in Sn doped ZnO nanorods.

Nanotechnology

Ortega Y, Dieker Ch, Jäger W, Piqueras J, Fernández P.
PMID: 20453289

ZnO nanorods containing different hollow structures have been grown by a thermal evaporation-deposition method with a mixture of ZnS and SnO(2) powders as precursor. Transmission electron microscopy shows rods with rows of voids as well as rods with empty...

Streaming currents in a single nanofluidic channel.

We report measurements of the streaming current, an electrical current generated by a pressure-driven liquid flow, in individual rectangular silica nanochannels down to 70 nm in height. The streaming current is observed to be proportional to the pressure gradient...
