“…The object is the bitumen BN 70/30 GOST 6617-76 RF, a petroleum resin obtained by thermal polymerization of C9 fraction of liquid pyrolysis products (plant "Slanci", Saint-Petersburg, Russia) TU 2451-024-78780418-2006 and oxidized with peracetic acid [4], which is formed in situ and is used as a modifier. The oxidation of the petroleum resin allows inclusion into the structure of the molecule of up to 13 % of epoxide groups, which later on will intensify the process of the composition condensation by macromolecular crosslinking [3,5]. Tetrabutoxytitanium (tetrabutilate titanium, TBT) -butyl orthotitanic acid -(C 4 H 9 O) 4 Ti was used as a hardening agent.…”

The possibility of using epoxidized petroleum resins for modification of bitumen was shown. The dependence of the properties of coatings based on polymeric-bitumen compositions of the number of modifiers, hardening agent and the curing temperature was investigated. The optimum process parameters for polymeric-bitumen compositions were identified. The resistance of the coatings to different environments was investigated.

“…To improve the adhesive properties of bitumen it is proposed to use the functional resins. [8][9][10][11][12][13][14][15] The peculiarity is that the resins contain different by nature functional groups (epoxy, peroxy, hydroxy, etc.) in their structure, which may react with bitumen component and form the cross-linked structures.…”

Hydroxyapatite nanoparticles were isolated from a biowaste, buffalo bone, via the thermal decomposition method. The resulting white powdered material was characterized by Fourier Transformed Infrared (FTIR) spectroscopy, X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and Energy Dispersive X-ray (EDX) analysis. The FTIR spectra confirmed that a heat treatment of the bone powder at the temperature at or above 1223 K removed the organic moieties leading to the formation of a pure inorganic biomineral. The XRD analyses showed that the obtained material was nanocrystalline HAp (nano-HAp) with an average grain diameter of 25 nm, while their rod-shaped particles with their tightly agglomerated morphology were confirmed by the SEM analysis. Besides Calcium (Ca), Phosphorous (P), and Oxygen (O), trace amounts of Aluminum (Al), Magnesium (Mg), Copper (Cu), Zirconium (Zr) and Carbon (C) were also found by EDX analysis. Antibacterial activity of nano-HAp against six standard isolates was investigated by the agar well diffusion method and found to be more susceptible to Acinetobacter baumannii while other standard strains such as Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus showed lesser susceptibility and no antibacterial activity was noticed against Salmonella typhi and Methicillin resistant Staphylococcus aureus (MRSA) with the analysed concentration of nano-HAp suggesting its potential application in biomedical fields.

Removal of lead from aqueous solutions was studied using nanocomposite absorbent of bentonite/-alumina. The novel absorbent was characterized using XRD, FT-IR and SEM-EDX. Absorption process optimization using response surface methodology (RSM) and experimental design was performed with central composite design technique. The effects of Pb(II) initial concentration, adsorbent dosage, and composite percentage on Pb(II) removal percentage and adsorption capacity were examined. The adsorption capacity of 166.559 mg/g and removal % of 82.9887 with desirability equal to 0.763 were obtained for optimal initial concentration of 200 mg•l-1, adsorbent dosage of 0.5 mg•l-1, and composite percentage of 7.08 % determined using RSM design. The equilibrium adsorption data were investigated by Langmuir, Freundlich and Dubinin-Radushkevich isotherm models. It was found that Freundlich isotherm model fits better compared with other models.
