This work is about the application of large-scale mi-crowave furnaces being suitable for the sintering of conductive structures deposited on standard plastic parts in industrial processes. The conductive structures are consisting of carbon or silver
Structural Aspects and Host Effects of the Chirality Transfer by Mesogenic Substituted Aminoalcohols

Molecular Crystals and Liquid Crystals. 626:1-11
In continuation of the investigations on chiral dopants derived from the aminoalcohols ephedrine and pseudoephedrine as chiral bivalent structure elements, a series of new agents bearing very different substituents has been synthesized. The products

The molecular dynamics in thin films of isotactic poly(methylmethacrylate) is investigated by broadband dielectric spectroscopy. No shifts in the mean relaxation time of the dynamic glass transition are detected down to a film thickness of 6.6 nm. Th

The separation of the evaporation from the catalytic reforming process is crucial for fuel processing. Unfavourable mixtures lead to degradation by local hot spots in the sensitive catalysts and formation of unwanted byproducts. Cool flames offer a c

We propose a novel fabrication method for realizing robust and solvent resistant honeycomb films by combining parylene deposition with the polymer auto-organization phenomenon leading to breath figures. Parylene CVD process is suitable for producing

Chiral dopants were obtained by acylation of enantiomerically pure ephedrine and pseudoephedrine with promesogenic carbonyl reagents. The products have been investigated with respect to their chiral transfer ability on nematic host matrices character
