Anisotropic characteristics analysis of 3D-printed optics

Grabe, Tobias; Biermann, Tobias; Bayerl, Maximilian; Lachmayer, Roland (Erlangen : Deutsche Gesellschaft für angewandte Optik, 2020)

The Additive Manufacturing of transparent materials enables cost efficient rapidprototyping of optically transparent components. The components are built layer-by-layer which can cause anisotropic optical properties. We ...
Dry friction of microstructured polymer surfaces inspired by snake skin

Baum, Martina J.; Heepe, Lars; Fadeeva, Elena; Gorb, Stanislav N. (Frankfurt am Main : Beilstein-Institut zur Förderung der Chemischen Wissenschaften, 2014)

The microstructure investigated in this study was inspired by the anisotropic microornamentation of scales from the ventral body side of the California King Snake (Lampropeltis getula californiae). Frictional properties ...
Experimentelle Entwicklung von Bondprozessen mit niedrigschmelzenden eutektischen Legierungen auf flexiblen Substraten mit niedriger Glasübergangstemperatur

Moakhar ep Bouguecha, Sonda (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2015-11-13)

Das übergeordnete Ziel dieser Arbeit besteht in der Grundlagenuntersuchung und Optimierung von eutektischen Bondprozessen (auch Anlegieren genannt) für die Befestigung von elektronischen Bauteilen auf flexiblen Substraten. ...
The future of short-range high-speed data transmission: Printed polymer optical waveguides (POW) innovation, fabrication, and challenges

Reitberger, T.; Stoll, T.; Hoffmann, G.-A.; Lorenz, L.; Neermann, S.; Overmeyer, L.; Bock, K.-H.; Wolter, K.-J.; Franke, J. (Bellingham, Wash. : SPIE, 2018)

One of today's megatrends in the industrial environment is additive manufacturing. Faster prototyping, customized products like hearing devices, integrated functions like heatsinks and many other opportunities are offered ...
In-line production, optronic assembly and packaging of POFs

Hachicha, Bernd; Overmeyer, Ludger (Amsterdam : Elsevier, 2014)

The importance of optical technology as a key technology is constantly increasing. In application areas, where the conventional use of electrical solutions for signal generation, signal transmission or signal reception is ...
The osteogenic and tenogenic differentiation potential of C3H10T1/2 (mesenchymal stem cell model) cultured on PCL/PLA electrospun scaffolds in the absence of specific differentiation medium

Baudequin, Timothée; Gaut, Ludovic; Mueller, Marc; Huepkes, Angela; Glasmacher, Birgit; Duprez, Delphine; Bedoui, Fahmi; Legallais, Cécile (Basel : MDPI AG, 2017)

The differentiation potential of mesenchymal stem cells (MSC) has been extensively tested on electrospun scaffolds. However, this potential is often assessed with lineage-specific medium, making it difficult to interpret ...
Preliminary results in anterior cervical discectomy and fusion with an experimental bioabsorbable cage - clinical and radiological findings in an ovine animal model

Daentzer, Dorothea; Floerkemeier, Thilo; Bartsch, Ivonne; Masalha, Waseem; Welke, Bastian; Hurschler, Christof; Kauth, Theresa; Kaltbeitzel, Daniel; Hopmann, Christian; Kujat, Bernd; Kalla, Katharina (Heidelberg : SpringerOpen, 2013)

Background: Bioabsorbable implants are not widely used in spine surgery. This study investigated the clinical and radiological findings after anterior cervical discectomy and fusion (ACDF) in an ovine animal model with an ...
Printing polymer optical waveguides on conditioned transparent flexible foils by using the aerosol jet technology

Reitberger, Thomas; Hoffmann, Gerd-Albert; Wolfer, Tim; Overmeyer, Ludger; Franke, Jörg (Bellingham, Wash. : SPIE, 2016)

The optical data transfer is considered as the future of signal transfer due to its various advantages compared to conventional copper-based technologies. The Aerosol Jet Printing (AJP) technology offers the opportunity ...
Replication of planar polymer micro-optical waveguides and components

Rezem, Maher (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)

Photonic integrated circuits represent a topic of increasing interest in the research community. Its attractiveness is linked to the potential wide range of applications in the elds of optical telecommunication, photonic ...
The role of surface-energy of carbon-based nano-particles in polymer-filler interaction and reinforcement of elastomer nano-composites

Fleck, Frank (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)

In this work, the role of carbon black (CB) as reinforcing material for elastomer composites was studied on various length-scales.The technique of static, volumetric gas adsorption was utilized to elucidate the energetic- ...
