Moscow, Russia

D. Mendeleev University of Chemical Technology of Russia has its roots going far back into the 19th century. Back then, professors from the Imperial Moscow Technical School came up with an idea of establishing an Industrial College in Moscow to train “Chemical and Mechanical Engineer Assistants”.This proposal received an enormous support on behalf of the Moscow City Duma on February 9, 1880, which passed a Decision to Build an Industrial College in Moscow to Commemorate the 25th Anniversary of the Russian Emperor Alexander II's Reign.

The PoLaRBEAR (Production and Analysis Evolution For Lattice Related Barrel Elements Under Operations With Advanced Robustness) project focuses on reliable novel composite aircraft structures based on geodesic technology aiming at a significant higher Robustness and Technology Readiness Level (TRL). While the global structural behavior of composite geodesic structures is investigated and understood in a top-down approach in EU-ALaSCA, PoLaRBEAR will follow up in a bottom-up approach on local level analyzing the geodesic structures in terms of in-operation demands for higher TRL. The main objectives of this research proposal are: Industrial highly automated process for cost efficient barrel manufacturing Advanced reliability of geodesic structures under operational loads Design rules for robust grid structures The aim is to promote a competent cooperation in the development of light, low-cost airframe fuselage structures made with a new generation of composite materials and based on geodesic / iso-grid technologies under operations. The proposal will enhance the cooperation in research and in innovation between the European Union and the Russian Federation in the field of civil transport aircraft.

The ALaSCA project focuses on maximum weight and cost reduction significant in airframes by developing manufacture-optimized lattice fuselage structures fulfilling fundamental aspects of airworthiness. The idea behind the ALaSCA project is to perform a comprehensive investigation starting with the beneficial geodesic design well-proven in space technology and transferring it to composite aircraft fuselage designs. The main objectives of this research programme are: a) Maximum weight and cost reduction by using lattice designs for fuselage structures. b) Development of manufacture-optimized lattice designs satisfying airworthiness requirements. c) Verification of airworthiness by manufacture and testing of representative lattice components. Since structural requirements and boundary conditions in rocket technology are quite different from those in aircraft fuselage design, the scope of this project covers the specific aspects of design, sizing, manufacture and testing of lattice structures that follow from aircraft requirements. The objectives will only be achieved when solutions to the following issues in terms of lay-out, design, sizing, manufacture, and testing are found: a) Pro-lattice aircraft configurations for maximum weight and cost savings b) Aircraft specific components treated in the lattice fuselage design. c) Lattice elements, i.e. examination in the aircraft-specific detailed design of loads from impact and internal pressure. Applying the above-mentioned methodology, the objectives will be achieved by main innovations in the following areas: a) Structural concepts for long service-life periods b) Design and dimensioning of cut-out surround structures c) Optimized floor-barrel interface. d) Barrel-barrel interface. e) Aircraft configurations reducing the demand for large cut-outs and interfaces in lattice fuselage sections. f) Process chain: preliminary design, sizing, detailed design, manufacturing, testing, validation, cost and weight analysis.

The main objective of the project is the development of the pilot scale production system of the new generation of nanoporous organic and hybrid aerogels with multiple functions for application in gas and humidity adsorption, personal care and food. Thereby the fast manufacturing in form of spherical particles will be in focus in order to reduce the process time and to decrease the overall process costs. Thereby the purpose is to insure the high porosity and internal pore size distribution of the particles in order to provide the high surface area, pore volume and defined pore size needed for good adsorption capability. The production of organic aerogel particles in sufficient amounts will firstly enable the possibility to build prototypes for the applications in gas and humidity adsorption and food and to perform the corresponding tests. Based on the results of the test the properties of aerogels will be fine-tuned for the corresponding real applications in industrial environments. By this means it is intended to increase the technology readiness level of organic aerogels production from TLR 4 to TLR 6 by the end of the project.

A series of novel non-symmetrical coumarin-fused BODIPY dyes were synthesised. Their absorption and emission properties are strongly influenced by substitution in the coumarin moiety. Diethylamino-substituted dyes showed near-IR emission with large Stokes shifts (up to 144 nm) and good fluorescence quantum yields. © 2013 The Royal Society of Chemistry.

Pressure-sensitive adhesives (PSAs) are finding increasing applications in various areas of industry and medicine. PSAs are a special class of viscoelastic polymers that form strong adhesive joints with substrates of varying chemical nature under application of light external bonding pressures (1-10 Pa) over short periods of time (1-5 s). To be a PSA, a polymer should possess both high fluidity under applied bonding pressure, to form good adhesive contact, and high cohesive strength and elasticity, which are necessary for resistance to debonding stresses and for dissipation of mechanical energy at the stage of adhesive bond failure under detaching force. For rational design of novel PSAs, molecular insight into mechanisms of their adhesive behavior is necessary. As shown in this review, strength of PSA adhesive joints is controlled by a combination of diffusion, viscoelastic, and relaxation mechanisms. At the molecular level, strong adhesion is the result of a narrow balance between two generally conflicting properties: high cohesive strength and large free volume. These conflicting properties are difficult to combine in a single polymer material. Individually, high cohesive interaction energy and large free volume are necessary but insufficient prerequisites for PSA strength. Evident correlations are observed between the adhesive bond strengths of different PSAs, and their relaxation behaviors are described by longer relaxation times. Innovative PSAs with tailored properties can be produced by physical mixing of nonadhesive long- and short-chain linear parent polymers, with groups at the two ends of the short chains complementary to the functional groups in the recurring units of the long chains. Although chemical composition and molecular structure of such innovative adhesives are unrelated to those of conventional PSAs, their mechanical properties and adhesive behaviors obey the same general laws, such as the Dahlquist's criterion of tack. © 2012 Wiley Periodicals, Inc.

The polarization effects associated with halogen bonding for the series of charge-transfer complexes Dm⋯X-Y, where donor molecules D m = NH3, H2O, H2S, C 2H4, CO and X-Y = Cl2, ClF, Br2, BrCl, ICl, I2, are characterized in terms of the quantum theory of atoms in molecules using the B3LYP/6-311** Kohn-Sham wave functions. We study the electrostatic potential features of separate donor and acceptor molecules, the change in atomic charges as well as the atomic electric dipole moments and their components, and the intra-atomic electron density dipole polarization and the bonding dipole moments resulting from the electron density redistribution between the molecules in the charge-transfer complexes. The equation linking the most negative electrostatic potential values in the donor molecules and the most positive values in dihalogen molecules with the stretching force constants was found using two-factor regression. It is demonstrated that the dipole polarization of the acceptor atom mirrors the strength of halogen bonding in complexes in a series of different donors and acceptors. An exponential relationship between the magnitude of the total atomic electric dipole moment of the acceptor atom and the intermolecular stretching force constant is established for weakly bounded complexes. © 2013 the Owner Societies.

The present review deals with the novel developments in melt growth techniques which have arisen mostly within recent five-ten years and focuses on recent progress in growing bulk crystals of dielectrics, however, many developments could be easily applied to the semiconductor growth technology. The scaling of size and yield of crystals grown from the melt, and various ways and tricks to improve crystal perfection via homogenization of melt composition and governing the heat and mass transfer are under consideration. Particular developments such as low-thermal gradient and low-melt level growth techniques, governing by heat field rotation and applying of low-frequency vibration, as well as the use of double crucibles and submerged baffles are considering. The paper also discusses the current problems of bulk crystal growth due to the competition with arisen alternative technologies of manufacture the bulk crystalline or quasi-crystalline materials including transparent ceramics and glass-ceramics as well as the solid-state single crystal growth technology. © 2011 Elsevier B.V.
