Zinc phosphate micro flakes as new corrosion inhibition additives in coatings and paints

Perre E., Albayrak S., Becker-Willinger C., INM - Leibniz Institute for New Materials, DE

Corrosion protection is a constant concern to steel manufacturers and users. Various processes were developed in the past to provide corrosion protection for steel such as metallic layers like e.g. zinc, coating of the metal [...]

Abuse Prevention by Controlled Release of Opioids from Micro to Nano-structured Silica Xerogel Delivery Systems

Toworfe G., Anku C., Radin S., Zeiger A., Ducheyne P., Flowers Sch of Technology & Management, DE

This study proposes that release concentrations, of opioid, not exceeding therapeutic target levels can be achieved by incorporating the dosage in a nano-structurally optimized delivery material.

Non-destructive imaging analysis of unstable foam structures using 3D computed tomography

Eggert A., Müller M., Nachtrab F., Dombrowski J., Rack A., Zabler S., Fraunhofer Institute for Integrated Systems IIS, DE

In this contribution a laboratory CT setup is presented allowing the acquisition of 3D data sets in less than 15 s. The suitability and possibilities of such a system for unstable foams and other porous [...]

Uptake Behavior of Glycoconjugated and Micellar-Encapsulated Quantum Dots on HeLa Cervical Cancer Cells

Merkl J.-P., Schmidtke C., Safi M., Muroski M., Alpers D., Tran H., Ostermann J., Kreuziger A.-M., Strouse G., Mattoussi H., Weller H., University of Hamburg, DE

Glyconanomaterials are of great interest for bio-imaging to understand biological processes, for instance metabolism, cell-cell or virus-cell interactions, gluconeogenesis, and cancer. Herein, we present a strategy for the biofunctionalization of fluorescent quantum dots (QDs) from [...]

Engineering of Recombinant Spider Silk Proteins Allows Defined Drug Uptake and Release

Scheibel T., Unibersity of BAyreuth, DE

Drug delivery systems allow tissue / cell specific targeting of drugs in order to reduce total drug amounts administered to an organism and potential side effects upon systemic drug delivery. Most drug delivery systems are [...]

Development of alternative binder for lithium ion battery based on epoxy resin

Bunzel F., Wagner M., Stammen E., Dilger K., Technische Universität Braunschweig, DE

The development of batteries for the e-mobility continuously creates new challenges for the researchers. To improve performance of lithium ion batteries, different approaches might be considered. Therefore the Institute of Joining and Welding (ifs) focuses [...]

Fine textured composite low friction coatings with combined corrosion protection ability

Becker-Willinger C., Kalmes P., Bentz D., INM - Leibniz Institute for New Materials, DE

A new class of multifunctional low friction coatings combining a low coefficient of friction of µ 1000 h in the neutral salt spray test on mild steel have been developed. The coatings possess a fine [...]

Encapsulation and controlled thermal release of vegetable oils from organic nanoparticles for functional coating applications

Samyn P., Stanssens D., University of Freiburg - Freiburg Institute for Advanced Studies, DE

Nanoparticle pigments of poly(styrene-maleimide) or SMI have been synthesized containing different vegetable oils that favourably can be applied as a barrier resistant coating against water and oil penetration onto paper substrates and regulate its surface [...]

Fluorescent-Plasmonic Quantum Dot-Gold based Nanohybrids: Basic Research for Next Generation Materials and Tracking of Biological Events

Merkl J.-P., Schmidtke C., Aldeek F., Safi M., Strelow C., Feld A., Kloust H., Heidari H., Bals S., Lange H., Mattoussi H., Weller H., University of Hamburg, DE

A novel hybrid nanoparticle is presented based on encapsulated fluorescent CdSe/ZnSe/ZnS core/shell/shell quantum dots (QDs) with zwitterionic capped gold nanoparticles (AuNPs). This hybrid is fully characterizes by variouse techniques including optical spectroscopy, (cryo) transmission electron [...]
