Nano-contact transfer with gold nanoparticles on PEG hydrogels and using wrinkled PDMS-stamps

Yesildag, Cigdem; Tyushina, Arina; Lensen, Marga (2017)

In the present work, a soft lithographic process is used to create nanometer-sized line patterns of gold nanoparticles (Au NPs) on PEG-based hydrogels. Hereby nanometer-sized wrinkles on polydimeth...

Novel wet micro-contact deprinting method for patterning gold nanoparticles on PEG-hydrogels and thereby controlling cell adhesion

Yesildag, Cigdem; Bartsch, Christoph; Vicente, Gonzalo de; Lensen, Marga C. (2017)

In the present work we introduce a novel method to create linear and rectangular micro-patterns of gold nanoparticles (Au NPs) on poly(ethylene glycol) (PEG) hydrogels. The strategy consists of rem...

Property-performance relationships of catalysts in the oxidative coupling of methane

Schmack, Roman (2017)

The catalytic oxidative coupling of methane (OCM) is a „dream reaction“ of heterogeneous catalysis, as it provides a direct conversion route of methane to the value-added and easily transportable C...

Underpricing und Private Equity

Seyfarth, Sebastian (2017)

Underpricing is often used to determine asymmetric information when companies first list their shares at the stock exchange. This paper examines the relation between pre-IPO private equity investme...

ACT-R model: "Modeling of Visual Search and Influence of Item Similarity"

Lindner, Stefan; Rußwinkel, Nele; Ahrlt, Lennart; Neufeld, Max; Schattenhofer, Lukas (2017-05-31)

A modeling approach addressing visual search in an array of items of differing similarity is introduced. The model is able to capture the effects found in a study that varies target-distractor simi...

Experimental Human-Robot-Interaction: A Handover-Interaction with BROMMI:TAK at a public science event.

Graf, Philipp; Marquardt, Manuela; Compagna, Diego (2017-06-16)

We conducted a Human-Robot Interaction (HRI) study during a science event, using a mixed method exper- imental approach with quantitative and qualitative data (adapted version of Godspeed Questionn...

Contactless visible light probing for nanoscale ICs through 10 μm bulk silicon

Boit, Christian; Lohrke, Heiko; Scholz, Philipp; Beyreuther, Anne; Kerst, Uwe; Iwaki, Y. (2015)

This paper explains why only optical techniques will be able to provide debug and diagnosis of bulk silicon FinFET technologies. In order to apply optical techniques through a convenient thickness ...

Development of a swirl-stabilized H2/O2 combustion system under humidified conditions

Tanneberger, Tom; Schimek, Sebastian; Kossatz, Max; Paschereit, Christian Oliver; Stathopoulos, Panagiotis (2017-04-19)

The use of renewable energy sources raises the demand of fast and flexible storage techniques as well as fast power availability. A promising storage approach is the production of hydrogen and oxyg...

Reforming the European Union Emissions Trading System (EU ETS)

Grosjean, Godefroy (2017)

Given the need to reduce greenhouse gas emissions to decrease the risk of dangerous climate change, economists have often argued in favour of carbon pricing. Carbon pricing can essentially take two...

Voraussetzungen und Hindernisse beim Zugang zu UVP-Dokumenten und Verfahrensinformationen

Odparlik, Lisa Friederike; Kerkemeyer, Andreas (2016)

Damit Verfahren mit Öffentlichkeitsbeteiligung gelingen können, bedarf es zuvor einer aktiven Information der Öffentlichkeit. Die fortschreitende Digitalisierung eröffnet hierbei den Behörden die M...

Are agencies turning a blind eye to public access to environmental assessment information?

Odparlik, Lisa Friederike (2015)

For environmental assessments (strategic environmental assessment (SEA) and environmental impact assessment (EIA)) a wide range of data and documents is gathered, processed, and produced. In planni...

Nanocrystalline silicon and silicon oxide contact layers for silicon heterojunction solar cells

Mazzarella, Luana (2017)

Crystalline-silicon solar cells are presently the main technology to supply the rapidly growing market for competitive photovoltaic electricity. To drive conversion efficiency of such cells further...

Experimentelle Untersuchungen zur Verformungsakkumulation und Tragfähigkeitsreduktion zyklisch belasteter Pfahlgründungen

Georgi, Steven (2017)

Confronted with the effects of wind and waves, the foundations for offshore wind turbines are exposed to cyclic and dynamic loads. In this respect, different types of driven pile foundations, eithe...

Access to information and the role of environmental assessment registries for public participation

Odparlik, Lisa Friederike; Köppel, Johann (2013)

International practice shows an increasing use of web-based Environmental Assessment (EA) registries or project websites to provide public access to information. In support of statutory public part...

Organisationsmodelle im öffentlichen und privaten Hochbau

Edquist, Love Erik (2017)

Diese Arbeit setzt sich mit Organisationsmodellen bei Hochbauvorhaben auseinander. Hochbauvorhaben in Deutschland stellen einen bedeutenden Ausgabenposten öffentlicher Haushalte dar. Immer wieder ...

Gesture-based user authentication on mobile devices using accelerometer and gyroscope

Guse, Dennis (2017)

Mobile devices offer their users lots of possibilities and a feeling of freedom. However, this freedom comes along with new security threats. Sensitive data might be stolen and abused, if an unauth...

Design and provability of a statically configurable hypervisor

Nordholz, Jan (2017)

In this thesis we develop a novel, minimalist design for Type I hypervisors and present a fully working prototype for the ARMv7 and ARMv8 architectures. We introduce its key design paradigm, the Pr...

Anisotropic plasmonic nanoparticle arrays for surface-enhanced biosensors

Gkogkou, Dimitra (2017)

Plasmonic structures exhibiting surface enhancement properties can lead to hypersensitive, label-free and analyte-specific detection of organic molecules. The motivation of this work is the realiza...
