Materials (Basel) 2021 Jul 13;14(14). Epub 2021 Jul 13.

Laboratoire de Chimie de la Matière Condensée de Paris, CNRS, Sorbonne Université, LCMCP, F-75005 Paris, France.

In the field of non-oxide ceramic composites, and by using the polymer-derived ceramic route, understanding the relationship between the thermal behaviour of the preceramic polymers and their structure, leading to the mechanisms involved, is crucial. To investigate the role of Zr on the fabrication of ZrC-SiC composites, linear or hyperbranched polycarbosilanes and polyzirconocarbosilanes were synthesised through either "click-chemistry" or hydrosilylation reactions. Then, the thermal behaviours of these polymeric structures were considered, notably to understand the impact of Zr on the thermal path going to the composites. Read More

Fungal Biol 2020 10 29;124(10):884-891. Epub 2020 Jul 29.

Winogradsky Institute of Microbiology, Research Center of Biotechnology of the Russian Academy of Sciences, 33, Bld. 2, Leninsky Ave., Moscow, 119071, Russian Federation. Electronic address:

The accumulation of low molecular weight cytoprotective compounds (osmolytes) and changes in the membrane lipids composition are of key importance for the adaptation to stress impacts. However, the reason behind the wide variety of osmolytes present in the cell remains unclear. We suggest that specific functions of osmolytes can be revealed by studying the adaptation mechanisms of the mycelial fungus Emericellopsis alkalina (Hypocreales, Ascomycota) that is resistant to both alkaline pH values and high sodium chloride concentrations.
