Photoinduced Birefringence and Liquid Crystal Orientation on Polymers with Different Azobenzene Content in the Main Chain.

In this paper, we give an overview of novel main-chain azobenzene-based fluorinated poly(arylene ether)s with different content of azo groups, aiming at providing a better understanding of the link between a number of N═N bonds and the macroscopic response of the material. We discuss chemical synthesis and molecular structure and report on a comprehensive analysis of the polymer properties, thermal behavior, and mechanical strength. We show that a higher content of azobenzene moieties reduces the mechanical strength of the polymer materials.

Reassessment of pore occlusion in some diatom taxa with re-evaluation of Mereschkowsky (Bacillariophyceae: Cymbellales) and description of two new genera.

In this article, the history and taxonomy of , the type species of the genus , was discussed. We investigated the structure of pore occlusions in and related genera. As a result, we propose a new classification for tectulum-like types of pore occlusions.

gen. nov.-A New Diatom Genus with Unusual Morphology Split Off from the Genus Bory.

A new naviculoid diatom genus, gen. nov., was described based on a detailed morphological investigation using light and scanning electron microscopy.

Is the New ? (Cymbellales), a New Genus Based on Taxa Previously Assigned to .

A new diatom genus Kulikovskiy, Glushchenko, Genkal and Kociolek gen. nov., was described with species Glushchenko, Kulikovskiy and Kociolek sp.
