Inverter Circuits Based on Low-Temperature Solution-Processed ZnO Nanoparticle Thin-Film Transistors

Wolff K., Vidor F.F., Hilleringmann U., University of Paderborn, DE

Promising enhancement-load inverter cuircuits using bottom-gated ZnO nanoparticle thin-film transistors and a poly(4-vinylphenol) (PVP) dielectric are demonstrated. The deposition of the ZnO active layer is done by spin coating of a colloidal dispersion. Due to [...]

Synthesis of nanocrystalline nitrate enclathrated zeolite with intermediate framework structure between sodalite (SOD) and cancrinite (CAN)

Buhl J.-Ch., Cramm S., Leibniz University Hannover, DE

Synthesis of nitrate enclathrated nanocrystalline aluminosilicate zeolite was performed in the system Na2O-SiO2-Al2O3-H20-NaNO3-(TEA) under superalkaline low temperature conditions at 333 K. Formation of nanoparticles occurred already after 3 hours with sizes not exceeding 50 nm [...]

Synthesis, tuning of electrical conductivity and self-assembly of niobium doped titania nanoparticles

Liu Y., Rathousky J., Bein T., Fattakhova-Rohlfing D., University of Munich (LMU), DE

Controlling the synthesis of ultrasmall, stable oxide nanoparticles of different compositions and functionality is a continuing quest of nanoscience. Here we report on a solvothermal procedure that enables the preparation of crystalline niobium-doped and undoped [...]

Synthesis and characterization of La0.75Sr0.25Cr0.5Mn0.5O3- nanoparticles using combustion method

Reddy Channu V.S., Holze R., Walker Jr. E.H., Kalluru R.R., Technische universtat of Chemnitz, DE

La0.75Sr0.25Cr0.5Mn0.5O3-δ (LSCM) perovskite phase nanoparticles were successfully synthesized by solution combustion method using different carriers (NTP, oxalic acid, and citric acid) after calcination of fired gel at 1200 ºC for 7h. Scanning electron microscopy (SEM) [...]

Joint Technology Initiative Clean Sky – The European Program Towards Ecologically Compatible Air Transportation

Kaulfersch E., Rzepka S., Michel B., Fraunhofer ENAS, DE

The paper aims to introduce ‘Clean Sky’, the largest European aeronautics research programme that will radically improve the impact of air transport on the environment while strengthening and securing aeronautics industry’s competitiveness. The results of [...]

Nanocrystalline NaBH4-enclathrated zeolite SOD: a model for the improvement of safeness and reactivity of boron hydride based hydrogen storage systems

Buhl J.-Ch., Rüscher C.H., Schomborg L., Stemme F., Leibniz University Hannover, DE

Boron hydride is an interesting material for hydrogen storage but to become widely accepted in techniques, several problems like the high reactivity of NaBH4 under atmospheric conditions have to be solved. The latter offers a [...]

NANOCYTES-Technology – Biomimetic nanoparticles for molecular recognition by molecular imprinting

Schreiber T., Niedergall K., Wojciukiewicz D., Gose T., Gruber-Traub C., Weber A., Hirth T., Tovar G.E.M., University of Stuttgart & Fraunhofer Gesellschaft, DE

Communication of living systems is done by molecular recognition. This central principle of the living world is performed at the contact sites of different objects such as single macromolecules or highly complex supramolecular assemblies as [...]

The challenges of statistical experiment design in process development

Ortloff D., Popp J., Process Relations GmbH, DE

Process development, especially in the high tech sectors, is an extremely complex task. The key challenge is developing a range of process recipes and testing these recipes via experimentation. These experiments can take a lot [...]

A visual approach on MEMS process modeling using device cross-sections

Schmidt T., Mielke M., Hahn K., Ortloff D., Popp J., Brueck R., University of Siegen, DE

With MEMS entering fast moving consumer markets the need for more efficient design concepts becomes apparent. A technology centered approach where a product is designed around a highly specialized and optimized technology cannot cope with [...]

Calibration and Validation Procedure for Reliable and Predictive High-level Transducer Models Suited for System-level Design

Khalilyulin R., Schrag G., Wachutka G., Münich University of Technology, DE

We present an elaborated parameter extraction and model validation procedure for high-level transducer models that are aimed for system-level design as well as for hardware-software co-simulation (Matlab/Simulink transducer model embedded in control circuitry) in order [...]
