Application of zinc and magnesium oxides nanoparticles in crosslinking of carboxylated butadiene-acrylonitrile rubber

Lipinska M., Zaborski M., Technical University of Lodz, PL

The aim of this work was to study the activity of several nanosized zinc and magnesium oxides in the crosslinking of carboxylated nitrile elastomer XNBR. The influence of the specific surface area, particle size and [...]

The morphology and properties of silica nanoparticles synthesized by sol-gel reaction in elastomer matrix

Lipinska M., Zaborski M., Technical University of Lodz, PL

In our studies the influence of different dispersing agents on the synthesis and character of silica particles prepared by a sol-gel reaction was investigated. The silica with different surface morphology was synthesized from tetraethoxysilane (TEOS) [...]

Solid Oxide Fuel Cell in the hybrid system – selection of the size and configuration

Milewski J., Warsaw University of Technology, PL

Based on the model, fuel cell size according to hybrid system is selected. The selection is made by using an optimizing process, in which both thermal-flow parameters and design parameters of the fuel cell were [...]

Utilization the heat accumulator in large heating system

Bujalski W., Badyda K., Milewski J., Warchol M., Warsaw University of Technology, PL

Cogeneration is currently one of the cheapest ways to generate electricity. The European Union promotes systems for combined heat and power generation. In Europe in general – and Poland in particular – there are numerous [...]

The Application of GHMRF to 3-D Synthetic Proliferation

Zubert M., Napieralska M., Napieralski A., Technical University of Lodz, PL

This paper presents a novel hypothetical tissue proliferation model of extraneuronal filaceous material consisting of accumulation of the amyloid beta-proteins. Proposed model is constructed using a 3-D Gaussian Hidden Markov Random Field obtained from fluorescent [...]

Study on Application of Piezoelectric Vibration Energy Harvesters for Powering of Wireless Sensor Nodes in Large Rotary Machine Diagnostic Systems

Pekoslawski B., Pietrzak P., Makowski M., Szafoni L., Napieralski A., Technical University of Lodz, PL

A condition monitoring of large rotary machines such as turbogenerators in power plants can be more convenient and less expensive when using a distributed measurement system with wireless sensor nodes. A battery-based powering of these [...]

Characterization of Silane Nanoadhesion by means of Dynamic Force Spectroscopy

Ptak A., Makowski M., Niemier M., Cichomski M., Gojzewski H., Czajka R., Poznan University of Technology, PL

Using a modified atomic force microscope the nanoadhesion between a silicon tip and a monolayer of 1H, 1H, 2H, 2H-perfluorodecyl-trichlorosilane was measured at different loading rates. Adhesion force-versus-loading rate curves could be fitted with two [...]

Silica-alumina composite monoliths with a hierarchical pore structure containing the MFI-type zeolitic films

Pudlo W., Pashkova V., Derewinski M., Jarzebski A.B., Institute of Chemical Engineering, Polish Academy of Sciences, PL

Materials with multimodal hierarchical porosity, containing pore networks in the range of micro-, meso- and macropores, attract considerable attention owing to their widespread application prospects in process industries (catalysts, sorbents), energy conversion and sensors. Here [...]

Engineering of efficient biocatalysts using nanostructured mesoporous silicate carriers

Szymanska K., Bryjak J., Jarzebski A.B., Institute of Chemical Engineering, Polish Academy of Science, PL

Immobilization of free enzymes/proteins on water-insoluble mesoporous silica (MS) supports is often applied to obtain efficient biocatalysts for various applications. Three methods were applied for enzyme bonding onto MS: (1) physical adsorption with subsequent crosslinking [...]
