Exploring the IR-limit of the Triplet-Triplet Annihilation Upconversion: Tetraaryltetraanthra[2,3]porphyrin – family

Filatov M., Ilieva I., Landfester K., Baluschev S., MPIP, DE

The main advantage of the techniques, using photon conversion is that conversion processes and devices can be considered and optimized independently, without affecting the particular physical properties of the operating photovoltaic material or device architectures. [...]

Determining the environmental benefit of artificial spider silk products

Lauterbach A.Y., Scheibel T., University of Bayreuth, DE

Spider silk is a highly interesting material with outstanding properties. Because the usage of natural spider silk for technical applications is not possible, the production of recombinant spider silk was established. This production process has [...]

Lysozyme – alginate nanocomplex: Effect of alginate composition

Fuenzalida J.P., Nareddy P.K., Moreno-Villoslada I., Moerschbacher B., Swamy M.J., Goycoolea F.M.A., Westfälische Wilhelms-Universität Münster, DE

In the present work we investigated the electrostatic self-assembly of nanoparticles of Lyz and different alginates (Alg A Mw~4kD and M/G~1.42 or Alg B Mw~7kD and M/G~5.00)to establish a relationship between the alginate structure and [...]

Establishment of a Matrix for Biorecognition Reactions based on Responsive Polymeric Compounds

Fandrich A., Buller J., Wischerhoff E., Laschewsky A., Lisdat F., Technical University of Applied Sciences Wildau, DE

Thermo-responsive polymers were synthesized and covalently bound to the surface of gold electrodes. Subsequently cyclic voltammetric and impedimetric measurements with so prepared working electrodes were realised in aqueous potassium ferro-/ferricyanide solutions at different temperatures. Significant [...]

Chitosan-based nanomaterials for drug delivery and antibiotic-free bacterial control

Vila-Sanjurjo C., Fuenzalida J.P., Menchicchi B., Coelho D., Engwer C., Hoffman S., Pereira S., Remuñán-López C., Alonso M.J., Vidal A., Moerschbacher B., Kollenbrock S., Fetzner S., Philipp B., Goycoolea F.M., Westfaelische Wilhelms Universitaet - Muenster, DE

Research focused on chitosan (CS)-based nanostructured materials has burgeoned in the past decade or so, particularly in the biosciences and bionanotechnology fields. Chitosan characteristics (Mw and degree of acetylation), as well as the processing conditions [...]

Multilayer Architectures of Enzymes on Electrodes for Sensorial Application – Influence of the Building Blocks on the Assembly Behaviour

Lisdat F., Technical University Wildau, DE

The presentation will illustrate how redox proteins can be arranged in multiple layers on electrodes while retaining full electroactivity without the use of mediators. Enzymes can be integrated into such systems to result in sensing [...]

Triplet-Triplet Annihilation Upconversion in Water Environment: Biocompatible and Non-invasive All-optical Temperature Sensing for Living Objects

Busko D., Dimitrova R., Turshatov A., Avlasevich Y., Landfester K., Baluschev S., Max Planck Institute for Polymer Research, DE

A realistic temperature sensing alternative for life-science objects could be the process of triplet-triplet annihilation upconversion in water environment (TTA – UC): It is inherently micro-scale sensing techniques – the sensing function is carried out [...]

Pseudocapacitive random and aligned nano-porous electrode materials for supercapacitors

Saruhan B., Gönüllü Y., Arndt B., German Aerospace Center, DE

Commercial electric double layer capacitors store energy in an electric field. This is caused by charged particles arranged on two electrodes consisting mostly of carbon, in the form of a double layer. Such double layer [...]

Methodology and tool support for micro- and nano product engineering for SMEs

Hahn K., Ortloff D., Mielke M., Brueck R., University Siegen, DE

The development of micro and nano tech devices such as MEMS (micro-electro-mechanical systems) and NEMS (nano-electro-mechanical systems) based on semiconductor manufacturing processes comprises the structural design as well as the definition of the manufacturing process [...]
