Nanomer® coatings containing flake-type zinc-manganese metal phosphate particles as corrosion protection additives for mild steel

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

Metal phosphates and in particular, zinc phosphates are known to show interesting protection effect on steel against corrosion. The detailed mechanism of their anticorrosive effect is still not fully understood yet. In this direction not [...]

VEROGLAZE – color and protection for metal

Piesslinger-Schweiger S., POLIGRAT GmbH, DE

VEROGLAZE is a new revolutionary method, which applies long living hard and dense protective layers of quartz glass onto solid surfaces of numerous materials like Steel, Stainless Steel, Aluminum, Copper Alloys, Zinc, concrete, ceramics, stone, [...]

Preparation, Characterization and Application of Nanocellulose

Volkert B., Hettrich K., Fischer S., Fraunhofer Institute for Applied Polymer Research IAP, DE

Novel spherical nano-scaled cellulose particles have been prepared by high-pressure homogenizing of four different types of pre-treated cellulose samples with MICROFLUIDIZER™ processor (MF) in aqueous media. One possibility of pre-treatment is a decrystallization step realized [...]

Novel fatty-acid assisted co-precipitation method for synthesis of the SrAl2O4:Eu2+, Sm3+ storage phosphor nanoparticles

Levchuk I., Römling L., Steimle M., Osvet A., Batentschuk M., Winnacker A., Brabec C.J., University of Erlangen-Nuremberg, DE

Biological and medical imaging is a key-stone for in-vivo and in-vitro monitoring necessary for basic research and for medical diagnostics. Inorganic nanoparticles have already been established as fluorescence markers due to their high stability and [...]

Structure determination of silicene nanoribbons on Ag(110)

Espeter P., Keutner C., Kleimeier N.F., Roese P., Shamout K., Wenzel G., Berges U., Zacharias H., Westphal C., TU Dortmund, DE

Since the discovery of graphene much interest came up in the graphene analoga from the carbon group. One of the most famous representatives is silicene. Silicene is known to crystallize in different configurations, depending on [...]

Semiconductor Equipment Assessment – An Enabler for Production Ready Equipment

Pfeffer M., Bauer A., Fraunhofer Institute for Integrated Systems and Device Technology (IISB), DE

Semiconductor devices today show a ubiquitous presence and are of strategic importance. The manufactured number of transistors per area is still growing along a semi-logarithmic plot over the years. However, Europe‘s position as a supplier [...]

Inkjet Printing of High κ-Dielectric Ceramic/Polymer Composite Thick Films

Mikolajek M., Binder J.R., Karlsruhe Institute of Technology (KIT), DE

Inkjet printing offers a high flexibility and therefore is increasingly gaining importance for the selective deposition of functional materials, for example in printed electronics. However, till today either particle based inks or inks based on [...]

Combined Device- and System-level Simulation of RF MEMS Switches

Schrag G., Künzig T., Niessner M., Wachutka G., Technical University of Münich, DE

We present two problem-adapted, tailored modeling approaches for RF-MEMS switches which, in principle, are applicable to any capacitive MEMS device. They are based on finite element analysis (FEA) combined with analytical, lumped-element, and reduced-order modeling [...]

New Designs for MEMS-Micromirrors and Micromirror Packaging with Electrostatic and Piezoelectric Drive

Gu-Stoppel S., Stenchly V., Kaden D., Quenzer H.-J., Wagner B., Hofmann U., Dudde R., Fraunhofer Institute Silicon Technology, DE

New devices of 1 and 2dimensional micro-mirrors based on new designs and new process capabilities using piezoelectric actuators are presented. For micro-mirrors an 8’’ wafer-level packaging process was developed using pre-processed borosilicate glass wafers. An [...]

Freestanding Membranes of Cross-Linked Gold-Nanoparticles: Novel Functional Material for MEMS/NEMS Applications

Schlicke H., Schröter C.J., Rebber M., Battista D., Kunze S., Vossmeyer T., University of Hamburg, DE

We present the focus of our current research, which is the investigation of the electronic and mechanical properties of freestanding gold nanoparticle (GNP) membranes, e.g. by micro bulge tests with atomic force microscopy (AFM) data [...]
