Influence of Environmental Conditions on Carbon Black Oxidation by Reactive Oxygen Intermediates
AbstractThe paper examined the influence of hydrogen peroxide and ozone and singlet oxygen co-agents on the functional groups of the carbon black surface. The influence of the ambient temperature and the concentration of the reactants on protogenic functional groups (carboxylic and phenolic) generating has been studied. To assess the functional composition methods of titration with alkali of different strengh, differential potentiometer, pyrolysis gas chromatography have been used. It was found that the carbon oxidation depends on the sample structure. It is shown that carbon oxidation with hydrogen peroxide depends on the co-agent nature. With singlet oxygen used as a co-agent, carboxyl groups with the lowest pKa of about 2are generated on the carbon surface. When using ozone pKa of the group is higher than 2

Optimizing the Conditions of Mechanochemical Synthesis of LiAl Layered Hydroxides
AbstractLiAl layered double hydroxides (LDH) are the promising compounds for application in base catalysis and as precursors of the supports for platinum catalysts. In the work, such systems were synthesized by mechanochemical method. The effect of composition of the initial mixture (Al(OH)3, Al(NO3)3, LiOH, LiNO3), material of milling bodies (steel or ceramic), and activation conditions (centripetal acceleration and activation time) on the properties of LiAl-LDH were studied. It was found that each of the synthesized systems is a polyphase one and contains not only the LDH phase but also the side phase of aluminum trihydroxide. In addition, the samples obtained with the use of steel milling bodies have a substantial amount of iron. The use of ceramic milling bodies makes it possible to obtain the LiAl-LDH phase under relatively mild conditions (acceleration of 300 m/s2 and activation time of 15min)

(DBP), the size of the agglomerates and the functional surface of the carbon black (CB) N375 was
investigated. It was established that in the process of mechanical activation, the number of oxygencontaining
groups on the surface CB increases to 0.34 meq/g and the size of the aggregates decreases
from 300 to 3-5 microns. At the same time, the amount of absorption of DBP decreases.

Objective: to develop a technology for obtaining the molded sorbent VNIITU1, to study its physicochemical and biomedical properties, and to evaluate its efficacy in preventing and treating pyoinflammatory complications in obstetrics.Materials and methods.Β The molded sorbent VNIITU-1 was designed from the carbon porous material based on nanodispersed carbon by mixing with a vehicle, extruding the mixture, drying the extrudate in an inert atmosphere, thermally treating and activating by steam, followed byΒ washing with distilled water and drying (TU 9398043710698342013). The molded sorbent VNIITU-1 is apyrogenic and nontoxicΒ (Toxicity Study Conclusion No. 1998.013.P dated 14.08.2013; Engineering Testing Assessment No. 12.404 ORTI/2013 datedΒ 26.08.2013), it is destined for single administration, sterile, placed in a removable thread capron mesh container, and used to treatΒ and prevent pyoseptic complications in puerperas at risk for infection, such as acute nonspecific postpartum endometritis. A total ofΒ 52 puerperas were examined and treated. They had been divided into 2 groups: a study group (n=37) and a comparison groupΒ (n=15). In the study group, the hemosorbent VNIITU1 as a porous carbon applicator was postpartum inserted into the uterine cavity, by concurrently performing traditional antibiotic therapy to prevent infectious complications. The comparison group receivedΒ only traditional antibiotic therapy. The uterine cavity aspirate was examined for IL1Ξ² and IL6 levels, its microbial profile, andΒ microbial growth patterns in culture media. The data were processed using a package of applied STATISTICA6.1 programs andΒ standard mathematical tables in Microsoft Excel. Descriptive and variation statistical methods were applied. The data were presented as Me [low quartilehigh quartile (LQHQ)]; two pre and posttreatment dependent variables were compared using theΒ Wilcoxon and Mann-Whitney tests.Results. The molded carbon sorbent VNIITU1 was found to have pronounced antibacterialΒ activity against S.aureus, P.aeroginosa, K.pneumonia, E.coli and S.agalactiae. Examination of lavages from the surface of the sorbent after its removal from the uterine cavity, by using a transmission electron microscope, revealed castoff epithelial cells, leukocytes, macrophages, and microorganisms, which determines the capacity of the sorbent to eliminate not only soluble toxins, but alsoΒ microorganisms and disintegrating cell elements. Conclusion. The proposed procedure to Β postpartum endometritis in puerΒ peras at risk for infection via insertion of the porous carbon applicator VNIITU1 into the uterine cavity is more effective than theΒ traditional approach and it can improve treatment results, by completely eliminating pathogens from the uterus and by reducing theΒ level of local proinflammatory cytokines.Π¦Π΅Π»Ρ β ΡΠ°Π·ΡΠ°Π±ΠΎΡΠ°ΡΡ ΡΠ΅Ρ

Objective: to study the specific features of sorption of some protein molecules (cytokines, immunoglobulins) in vitro, by using the carbon hemosorbent designed at the Institute of Hydrocarbon Process Problems, Siberian Branch, Russian Academy of Sciences.Materials and methods. 42 plasma samples from 14 patients with peritonitis were examined before and after hemosorption. Plasma was perfused through the hemosorbent with a plasma:hemosorbent ratio of 10:1 and a 5-cm3-column volume on an Π£ΠΠΠ ΠΠ-1 at a rate of 15 ml/min.Results. The designed hemosorbent was found to absorb proinflammatory cytokines, such as tumor necrosis fac-tor-a and interleukin-1/J more than the hemosorbent VNIITU-1, and to significantly unchange the content of immunoglobulins M, G, and A. The absorptive capacity of the new hemosorbent was 48% greater than that of VNIITU-1.Conclusion. The findings may serve as a guide for further more in-depth studies of the specific features of sorption of plasma protein molecules from critically ill patients, by employingjust this carbon sorbent.Β Π¦Π΅Π»Ρ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ .
