High-quality multiwall carbon nanotubes (MWNTs) were produced by a simple one-step technique. The production of MWNTs was based on thermal decomposition of the mixture of a liquid phase organic compound and ferrocene. High degree of alignment was noticed by scanning electron microscopy. The aspect ratio of as-synthesized MWNTs was quite high (more than 4500). Transmission electron microscopy analysis showed the presence of the catalytic iron nanorods at various lengths of MWNTs. Raman spectroscopy was used to know the quality of MWNTs. The ratio of intensity of the G-peak to the D-peak was very high which revealed high quality of MWNTs. Magnetotransport studies were carried out at low temperature and a negative MR was noticed.

This paper proposes a novel method to generate strategic team AI pathfinding plans for computer games and simulations using probabilistic pathfinding. This method is inspired by genetic algorithms (Russell and Norvig, 2002), in that, a fitness function is used to test the quality of the path plans. The method generates high-quality path plans by eliminating the low-quality ones. The path plans are generated by probabilistic pathfinding, and the elimination is done by a fitness test of the path plans. This path plan generation method has the ability to generate variation or different high-quality paths, which is desired for games to increase replay values. This work is an extension of our earlier work on team AI: probabilistic pathfinding (John et al., 2006). We explore ways to combine probabilistic pathfinding and genetic algorithm to create a new method to generate strategic team AI pathfinding plans.

Ecological Aspects

The paper presents up-to-date and perspective requirements for the quality of diesel fuels. The effect of chemical, as well as fractional composition on the quality of diesel fuels is marked. The capability of obtaining prospective ecologically friendly diesel fuel based on the mixture of Azerbaijani oils via hydro-treatment in the presence of the catalyst of alumonickelmolibdene is noted. Ecologically friendly diesel fuels with ASTMD 4294 by sulfur - 0.039 % mass, ASTMD 3227 by sour sulfur - 0.006 % mass, ASTMD 5708 by metals: V ˃ 2 mg/kg, Ni ˃ 1 mg/kg, Fe ˃ 3 mg/kg, Na ˃ 8 mg/kg, as well as with the freezing temperature of ASTMD 97 – 50 оС have been obtained. Such kinds of diesel fuel meet EN standards and provide environmental safety in storage and transportation to the European countries. The prospect of obtaining and using buffer plug (mixture of petroleum products) during consistent pumping of various sorts of oil products without ecologic-economic risks of jet fuels is shown as well.

Carboxyl end-functionalized poly(3-hexylthiophene) (P3HT-COOH) was grafted chemically with CdSe nanocrystals (NCs) by a phosphine-free method. The particle quality of P3HT-COOH/CdSe nanocomposites was better than that of P3HT/CdSe nanocomposites, which were synthesized using the same method. Nanocrystals with controllable particle size exhibited a wurtzite crystalline structure and showed excellent nanocrystal dispersion in the P3HT-COOH matrix. Photoluminescence (PL) characterization performed on nanocomposites suggested the efficient charge transfer at the P3HT-COOH/CdSe interface. This approach based on the phosphine-free method is not only environmentally friendly but also highly efficient.

Expediency of using natural glauconite material as a basis for the production of an environmentally friendly sorbent with hydrophobic and magnetic properties for liquidating oil and oil products spills mechanically and using a magnetic field has been substantiated and experimentally proved. Fractional, elemental and oxide compositions of the original mineral have been studied. The structure of glauconite fraction 0.045-0.1 mm has been investigated by transmission electron microscopy. It was found that the surface of the sample particles is heterogeneous with a large number of pores and cracks. Based on the experimental data, the optimal conditions for the production and use of powder and granular sorbents based on glauconite with specified properties were determined, at which a high degree of recovery (more than 90%) of oil with water and hard surfaces. The optimum temperature for obtaining a magnetic oil sorbent is 400 °C. The doses of stearic acid and iron (III) oxide were established at 5 wt. %, which provide hydrophobicity and magnetic properties to the synthesized sorbent. A high degree of oil (97%) and oil (98%) recovery when using a sorbent is achieved at a ratio of 1: 10 to sorbate. To eliminate oil and oil product spills, it is proposed to use granular ferromagnetic sorbents obtained by introducing carboxymethyl cellulose into the modified glauconite composition. oil and oil products granular sorbent increases in comparison with the original mineral by 1.2–2.2 times. Technological schemes for obtaining ferromagnetic hydrophobic and granular sorbents based on glauconite for collecting oil and oil products from water and solid surfaces have been developed. The synthesized sorbents are characterized by high efficiency, low cost, and environmental friendliness.

A consortium of microorganisms were isolated from TC-1 fuel form, each member of which is capable of consistently degrade hydrocarbons’ different fractions. The 5 strains of hydrocarbon-oxidizing bacteria (PSB) were identified and isolated from TS-1 jet fuel. Their physiological and biochemical features are defined. All strains exhibit positive catalase activity. It is determined that all UOB strains, producing exogenous and endogenous surfactants, are capable to growth on media with different fraction of hydrocarbons. The study of these associations allows to create effective preparations for bioremediation in the elimination of accidental spills of oil and petroleum products.
