The Russian-British round table, dedicated to the development of heterocyclic chemistry, was held in February 2012, in the conference hall of the presidium of the RAS Ural Branch. The meeting was organized by the General Consulate of Great Britain in Yekaterinburg, Ural Federal University and RAS Ural Branch. According to Mariya Bychkova, Ural scientists, in particular, from the Institute of Organic Synthesis named after I. Postovsky (IOS) are closely coordinating with colleagues from Great Britain in this sphere of knowledge. It is true, scientists in England are more engaged in creation of appropriate new materials and studies of liquid crystals, while our specialists focus on working out of antiviral preparations.
Professor Duncan Bruce from the University of York dwelt in his speech on the unique properties of liquid

crystals, discussed at the meeting, which occupy an intermediate position between liquids and solids, possessing properties of both. The unique combination of regulated state of their molecules and fluidity stipulates anisotropy of the phenomena, interesting for specialists-dependence of the properties on the direction of action. Besides, the British scientist demonstrated the variety of forms of the latter, resembling a claim, ring, pizza or even a banana. As a result, today the world market is well acquainted with the so-called plane-panel displays, i.e. television sets, phones, calculators, etc. But very often we even do not know we are dealing with mesomorphic structures in everyday life. For example, they make up cellular membranes of our organism, in everyday life they are a basis for active components of all detergents. And the cobweb is durable only because it passes a mesomorphic stage before "freezing".
Then professor Bruce emphasized: further studies of liquid crystals will bring to mankind a mass of discoveries and creation of absolutely new substances, the ... Читать далее
