The second Conference of CIS Countries "Sol-Gel-2012"

Sevastopol, Crimea, Ukraine

September 18-20, 2012

The Second Conference of CIS Countries "Sol-Gel-2012" was held on September 18-20, 2012 in Sevastopol (Crimea, Ukraine) at the recreation hostel "Sevastopol". It was organized by the Institute for Sorption and Problems of Endoecology of NAS of Ukraine and Chuiko Institute of Surface Chemistry of NAS of Ukraine (Kiev) – at the support of Grebenshchikov Institute of Silicate Chemistry of RAS (St. Petersburg). Participation in the Conference took 135 scientists and experts from different scientific centers of the Russian Federation (Moscow, Apatity, St. Petersburg, Belgorod, Syktyvkar, Kazan, Ivanovo, Ekaterinburg, Novosibirsk, Krasnoyarsk, Tomsk, Vladivostok), Ukraine (Kyiv, Dnipropetrovsk, Donetsk, Kharkiv, Odesa, Lviv), the Republic of Belarus (Minsk, Gomel), Armenia (Yerevan), Kazakhstan (Almaty). About half of the conference participants were young scientists and graduate students, which will certainly contribute to their creative growth. In addition, there were 15 researchers from other countries, such as Austria, Hungary, Lithuania, Canada, Slovenia, Poland, Sweden, Czech Republic, and Finland, who took part in the Conference.

“Sol-Gel-2012” covered the following sections:

Theoretical aspects of sol-gel process;
Sol-gel synthesis and study of nanoparticles;
Sol-gel films, coatings and membranes;
Hybrid inorganic and organic-inorganic sol-gel materials;
Xerogels, glass and bulk ceramic materials, sorbents, and catalysts synthesized by sol-gel method;
Biomedical materials.

During the Conference, there were presented 17 plenary lectures and 30 short oral presentations. 110 posters were discussed during the two poster sessions. The opening speech was delivered by the Co-Chair of the Conference, Academician of NASU V.V. Strelko. In the beginning, he read the address of the President of National Academy of Sciences of Ukraine, Acad. Boris Paton, to the participants of "Sol-Gel-2012", and then briefly outlined the historical aspects of chemistry and technology of sol-gel processes. Prof. O.O. Shylova of Grebenshchikov Institute of Silicate Chemistry of RAS conveyed video greeting from the Co-Chair of the Conference, Academician of RAS V.Ya. Shevchenko, who, unfortunately, could not attend “Sol-Gel-2012”.

The first plenary lecture was delivered by the president of ISPE NASU, Academician of NASU V.V. Strelko, "Sol-Gel Method for the Synthesis of Sorbents and Catalysts". The report was rich in essential facts and important theoretical generalizations. The Institute for Sorption and Problems of Endoecology has significant achievements in this area and offers a wide range of sorbents obtained via sol-gel method for selective extraction and concentration of cesium and strontium ions. The logical continuation of this theme was the lecture by Prof. N.A. Shabanova of Mendeleev University of Chemical Technology of Russia (Moscow) "Colloidal Silica: reactive properties and aggregation stability". Prof. N.A. Shabanova as an author of several books in this field, considered the impact of various factors on the aggregation stability of colloidal silica, which is very important from practical point of view. Theoretical aspects of sol-gel processes were also discussed in brief oral reports by Dr. M.S. Melhunov of Boreskov Institute of Catalysis SB RAS (Novosibirsk), "Mechanisms of self-organization in sol-gel and template synthesis" and Prof. S.D. Kyryk of Siberian Federal University (Krasnoyarsk) "Hydrothermal stability of mesostructured silicate MCM-41 in terms of the path of its formation". Much interest aroused the reports by Dr. T.H. Honina from the Postovsky Institute of Organic Synthesis, UB RAS (Ekaterinburg) "Polyolates of silicon and titanium in sol-gel process", Dr. S.I. Meleshevych from ISPE NASU (Kyiv) "Influence of hydrothermal treatment on the physico-chemical properties of individual and mixed gels based on SiO2, ZrO2, TiO2”, PhD student K.V. Ilyina of Boreskov Institute of Catalysis SB RAS (Novosibirsk) "Aerogels: synthesis, research, applications". The authors, in their reports have demonstrated the opportunities for the synthesis of new materials using alternative precursors and different methods of processing of the derived gels.

The work of the second section of the Conference was launched by the lecture by the renowned expert, Prof. S. Barany from Myshkolts University (Hungary) "Stabilization of dispersed systems/nanoparticles with polymers," in which he examined in detail the influence of the nature of the polymer, its molecular weight, charge density, and size of the particles and their concentration on the stabilization of colloids. Academician of Lithuanian Academy of Sciences, Prof. A. Kareiva (Vilnius) in his plenary report "Synthesis silica-carbon nanotube composites by sol-gel method" showed that upon the receipt of such composites by «spin-coating technique», nanotubes aggregation is critical, and outlined the ways to avoid it. Interesting aspects of the synthesis of nanomaterials, including nanoparticles have also been considered in short reports by Prof. V.P. Tolstoy from St. Petersburg State University "’Layer-by-layer’"synthesis of nanomaterials using colloid solutions as reagents”, Dr. I.V. Melnyk of Chuiko ISC NASU (Kyiv) "Functionalized silica spherical particles," Dr. H.M. Murashkevych of Belarusian State Technological University (Minsk) "Nanosize composite materials in the system SiO2-TiO2”, Dr. I.A. Farbun of ISPE NASU (Kyiv) "Citrate method for obtaining functional oxide materials”, Dr. O.O. Aleksiyenko of Gomel State Technical University (Gomel) "High-silica glasses, structured with recovered bimetal nanoparticles".

Very important in terms of technological implementation was plenary lecture by Prof. O.O. Shylova from Grebenschykov ISC of RAS "Features of synthesis and structure of oxide composite and hybrid coatings, obtained from silica sols doped with inorganic and organic substances". It examined in detail the mechanism for formation of alloying meso- and macro- phases, mechanism for preparation of boron-containing coatings and the conditions of sol-gel synthesis, which contribute to avoiding macro heterogeneities in doped silica coatings”. Prof. Y. Djaoued of Universite de Moncton (Canada) in his lecture "Sol-gel synthesis of porous tungsten oxide thin films: application in electrochromic and photochromic devices" also touched on the implementation in practice. This aspect was also partially considered in the lecture by Corr.-member of NASU, Prof. V.V. Shevchenko of Institute of Macromolecular Chemistry of NASU "Organic-inorganic proton conducting membranes obtained by sol-gel method for fuel cells”, and in the speech by Dr. O.A. Dmytriyeva of Institute of Physics and Technology (Almaty, Kazakhstan) "Effect of NH4F on the structure and physical properties of thin films of SnO2, synthesized by sol-gel method". Considerable attention was devoted to the impact of synthesis conditions on the structure and properties of thin films and membranes, and their innovative application in the messages by Prof. V.V. Kozyk of Tomsk State University "Target sol-gel synthesis of thin films multifunctional materials based on oxides of 3,4,5 groups", Dr. N.P. Smirnova of ISC NASU "Nanostructured films of mixed oxides based on titanium dioxide: synthesis, structure, electronic structure, photocatalytic properties," Dr. P.V. Kryvoshapkina of the Institute of Chemistry (Komi Science Centre, UB RAS) "Study of the structure of alumina ceramic membranes," Dr. A.I. Ivanets of IGIC NASB (Minsk) "Syntheis of silica membrane materials by sol-gel method."

Sections 4 and 5 of the Conference devoted to hybrid materials, gels, and glasses aroused much curiosity of the participants. Prof. A. Khachatryan of Yerevan State University (Armenia) in his plenary report "Some chromatographic peculiarities of polymer-mineral packing materials" considered the peculiarities of synthesis of silica microspheres by hydrothermal treatment of mesoporous silica, and the subsequent deposition of the polymer layer on the surface of spherical particles for their effective application in reversed-phase HPLC. Possibilities of using sol-gel method for the synthesis of selective sorbents and ion chemical sensors has been shown in the reports by Prof. A. Lobnik of the University of Maribor (Slovenia) "Sol-gel based optical chemical sensors", Prof. Yu.L. Zub of Chuiko ISC NASU "Hydrolytic polycondensation reaction of alkoxysilanes in the synthesis of hybrid organic-inorganic materials", Dr. Ye.K. Papynova of the Institute of Chemistry FED RAS (Vladivostok) "Template synthesis of porous calcium silicates using siloxane-acrylate emulsions", Dr. M. Barczak of M. Curie-Sklodowska University (Lublin, Poland) "SBA-15 and SBA-16 mesoporous silicas as sorbents of heavy metal ions", Prof. V.V. Milyutin of Frumkin Institute of Physical Chemistry and Electrochemistry RAS (Moscow) "Modern sorption materials in radiochemistry and purification of radioactively contaminated wastewater", Corr.-member of RAS, Prof. A.I. Nikolayev of Tananayev Institute of Chemistry and Technology of Rare Elements and Mineral Raw Materials (Kola Scientific Center, RAS) "Synthesis of inorganic ion exchangers using colloidal sol-gel titanium-containing precursor", Corr.-member of NASU B.Yu. Kornilovych of the National Technical University of Ukraine "Kyiv Polytechnical Institute" "Sol-gel synthesis of sorbents from natural layered silicates".

At the end of the Conference there was delivered a report by a renowned expert, Prof. V.G. Kessler of Swedish University of Agriculture Sciences (Uppsala) "Metal-organic sol-gel synthesis, surface modification and application aspects for biocompatible metal oxide nanomaterials," where he demonstrated the possibility of effective use of surfactants to control the porous structure of metals oxides. Dr. K. Soukup of the Institute of Chemical Processes Fundamentals of AS CR (Prague), in his report "Electrospinning Technique for preparation of biomedical materials" drew attention to the opportunities of promising new methods of synthesis of nanofibers to be used in membrane formation, etc. Finally, Dr. V.K. Ivanov of IGIC of RAS (Moscow) in his speech "Nanocrystalline cerium dioxide - a promising material for biomedical applications" presented the results of interdisciplinary studies of the mechanisms of formation, development of methods of directed synthesis, physico-chemical properties and biological activity of nanocrystalline cerium dioxide.

As a result of the Conference, there was achieved one of its objectives: to strengthen mutually beneficial research cooperation between researchers from the CIS countries and other foreign countries. Undoubtedly, this Conference gave new impetus to the research in chemistry and technology of sol-gel processes in the CIS countries.

Conference proceedings will be published in a special issue of journal "Physics and Chemistry of Glass" (ISC, RAS) and the Journal of Sol-Gel Science and Technology (Springer).

The following, Third Conference of CIS Countries "Sol-gel-2014" is to be held in Suzdal (organizer – Krestov Institute of Solution Chemistry of RAS, Ivanovo, Russia), and the Fourth Conference of CIS Countries "Sol-gel-2016" - in Yerevan (organizer - Yerevan State University, Armenia).
