Self-Assembly of a Perfluorinated Amphiphilic Cyanine Dye into Branched Tubular J-Aggregates.

The self-assembly process is governed by the individual constituents of molecules through precise non-covalent interactions. Amphiphilic cyanines are intriguing in supramolecular chemistry due to the large polarizability of their delocalized π-electron systems, their tuneable optical properties and their ability to form well-defined self-assembled structures in different media. Here we present the synthesis of a novel tetrahydroxy amphiphilic carbocyanine dye with perfluoro alkylated chains -(CH)-(CF)-CF as hydrophobic segments and aminoproanediol as hydrophilic segment.

Fluorinated dendritic amphiphiles, their stomatosome aggregates and application in enzyme encapsulation.

Enzymes are more selective and efficient than synthetic catalysts but are limited by difficult recycling. This is overcome by immobilisation, namely through encapsulation, with the main drawback of this method being slow diffusion of products and reactants, resulting in effectively lowered enzyme activity. Fluorinated dendritic amphiphiles were reported to self-assemble into regularly perforated bilayer vesicles, so-called "stomatosomes".

Photosensitisation and green egg yolks in laying hens caused by the feeding of ensiled alfalfa leaves.

1. The present study was carried out to determine the effects of feeding ensiled alfalfa leaves (ALS) as an alternative protein source to laying hens under the terms of an organic diet. Due to the occurrence of unexpected negative health effects and undesirable egg yolk pigmentation in the test groups the trial was prematurely stopped and further analysis was conducted to evaluate the responsible substances.

A comparison of two manual catching methods of broiler considering injuries and behavior.

The aim of this study was to compare the 2 manual catching methods in terms of injuries and behavior. Throughout 12 loadings on practical farms with the same standard, 1 container each was caught using the one-legged (1LCM) and 1 using the two-legged catching method (2LCM). The animals were filmed during loading to evaluate their behavior and subsequently examined regarding injuries.
