Detection and neutralization of soil contamination in the event of an emergency leakage of petroleumbased substances from a transmission pipeline

Andrzej PAPLIŃSKI*, Magdalena Piros – Faculty of Mechatronics and Aerospace, Military University of Technology in Warsaw, Poland Please cite as: CHEMIK 2016, 70, 6, 326–335 An increasing role of hydrocarbon substances is a feature of contemporary civilizational processes. Hydrocarbon substances are becoming a very common raw material, used in an increasingly wide range of products; they are also a necessary energy source. Technologies using modified hydrocarbon structures allow for manufacture of lightweight products with a durability rivalling...

Thermally activated delayed fluorescence – as a solution to the low yield problem of the fluorescent OLEDs

Piotr PANDER* - Department of Physical Chemistry and Technology of Polymers, Faculty of Chemistry, Silesian University of Technology, Gliwice, Poland Please cite as: CHEMIK 2016, 70, 6, 318–325 The development of display technologies has begun with the invention of the cinematograph; whereas a next important step was the cathode ray tube. CRT screens reached a high degree of development at the turn of the century, but they have been virtually superseded today by the liquid crystal displays...

Mesoporous carbon materials as promising catalysts for oxidative dehydrogenation of alkanes

Sebastian JARCZEWSKI*, Piotr KUŚTROWSKI – Faculty of Chemistry, Jagiellonian University, Kraków, Poland Please cite as: CHEMIK 2016, 70, 6, 298–309 From the beginning of the twentieth century, a systematic growth of demand for high volume products of chemical industry has been observed [1]. A rapid economic development of Asian (especially China, India and Middle East) as well as African countries suggests that during the next decades a further growth of such production should be expected [2]. It...

Role of various types of shape-selectivity in catalysis, exemplified by diisopropylnaphthalene isomers

Robert BRZOZOWSKI* – Industrial Chemistry Research Institute, Warsaw, Poland Please cite as: CHEMIK 2016, 70, 5, 310–317 Reactions of diisopropylnaphthalene (DIPN) synthesis are excellent examples how we can control isomeric composition of the product by exploiting shape-selectivity phenomenon and selecting proper reaction conditions. Moreover, these reactions are excellent examples illustrating main types of shape selectivity, such as substrate selectivity, product selectivity or transition state selectivity and also they prove an important role of the external surface of...
