Methodology for modeling of the jet formation process in linear sharped charges

Methodology for modeling of the jet formation process in linear sharped charges Andrzej WOJEWÓDKA, Tomasz WITKOWSKI ? Faculty of Chemistry, Silesian University of Technology,Gliwice; Poland Please cited as: CHEMIK 2011, 65, 1, 28-35 Linear shaped charges are used in the mining industry, industry, police, army, and in many other braches of industry. Methods of computer modeling can be used more widely if geometrical and material parameters are selected more accurately. Standoff dstance is one of such parameters that can be optimized using computer...

Hydrazine complexes of transition metals as perspective explosives

Hydrazine complexes of transition metals as perspective explosives Andrzej WOJEWÓDKA, Janusz BEŁZOWSKI - Silesian University of Technology, Faculty of Chemistry; Gliwice; Poland Please cited as: CHEMIK 2011, 65, 1, 20-27 Synthesis of nitrate and perchlorate complexes of cobalt, nickel, cadmium, zinc and chromium with hydrazine was done. Structure of obtained compounds was confirmed by instrumental methods, like: infrared spectroscopy, elemental analysis and x-ray fluorescence spectroscopy. Obtained compound was tested for them friction, impact and electrostatic sensitivity. Keywords: hydrazine complexes, explosives, friction sensitivity, impact sensitivity, electrostatic sensitivity Read more: Read more

The covalent grafting of polymers to the solid surface

The covalent grafting of polymers to the solid surface

Agata BLACHA, Katarzyna KRUKIEWICZ, Jerzy ŻAK - Silesian University of Technology, Faculty of Chemistry - Department of Physical Chemistry and Technology of Polymers, Gliwice; Poland Please cited as: CHEMIK 2011, 65, 1, 11-19 In this literature review the processes of the solid surface grafting are presented, which lead to the creation of the molecular surface polymeric structures known as polymer brushes. This is an area of nanotechnology, which offers perspective applications in the organic...
