Abstract
An investigation was carried out on humic substances (HSs) isolated from the coal of the Kansk-Achinsk basin (Krasnoyarsk Territory, Russia). The coal HSs demonstrate the main parameters of molecular structure inherent to this class of natural compounds. An assessment was performed for the chemical, microbiological, and pharmacological safety parameters, as well as the biological efficacy. The HS sample meets the safety requirements in microbiological purity, toxic metals content (lead, cadmium, mercury, arsenic), and radionuclides. The presence of 11 essential elements was determined. The absence of general, systemic toxicity, cytotoxicity, and allergenic properties was demonstrated. The coal HS sample was classified as a Class V hazard (low danger substances). High antioxidant and antiradical activities and immunotropic and cytoprotective properties were identified. The ability of the HS to inhibit hydroxyl radicals and superoxide anion radicals was revealed. Pronounced actoprotective and nootropic activities were also demonstrated in vivo. Intragastric administration of the HS sample resulted in the improvement of physical parameters in mice as assessed by the "swim exhaustion" test. Furthermore, intragastric administration in mice with cholinergic dysfunction led to a higher ability of animals with scopolamine-induced amnesia to form conditioned reflexes. These findings suggest that the studied HS sample is a safe and effective natural substance, making it suitable for use as a dietary bioactive supplement.

Abstract
The main objective of this study was to assess the usefulness of the low-quality brown coal, ash obtained as a result of its combustion, as well as used gear oil for the production of mineral-carbon adsorbents. The adsorbents were characterized in terms of textural parameters, acidic-basic character of the surface, mineral matter contribution to the structure, as well as their suitability for drinking water purification. Adsorption tests were carried out against two synthetic dyes-methylene blue and methyl orange. In order to understand the nature of the organic pollutants adsorption, the effect of the initial dye concentration, temperature, and pH of the system as well as the phase contact time were investigated. The obtained mineral-carbon composite and activated carbons significantly differed not only in terms of the elemental composition and chemical character of the surface (from slightly acidic to strongly alkaline), but also showed a very diverse degree of specific surface development (from 21 to 656 m2/g) and the type of porous structure generated (from micro/mesoporous to typically mesoporous). Adsorption tests showed that the efficiency of organic dye removal from aqueous solutions primarily depends on the type of the adsorbent and adsorbate applied, and, to a lesser extent, on the temperature and pH of the system. In turn, kinetic studies have shown that the sorption of dyes on such materials is consistent with a pseudo-second-order kinetics model, regardless of the type of adsorbed dye.

Abstract
Effective density (ρeff) is an important property describing particle transportation in the atmosphere and in the human respiratory tract. In this study, the particle size dependency of ρeff was determined for fresh and photochemically aged particles from residential combustion of wood logs and brown coal, as well as from an aerosol standard (CAST) burner. ρeff increased considerably due to photochemical aging, especially for soot agglomerates larger than 100 nm in mobility diameter. The increase depends on the presence of condensable vapors and agglomerate size and can be explained by collapsing of chain-like agglomerates and filling of their voids and formation of secondary coating. The measured and modeled particle optical properties suggest that while light absorption, scattering, and the single-scattering albedo of soot particle increase during photochemical processing, their radiative forcing remains positive until the amount of nonabsorbing coating exceeds approximately 90% of the particle mass.

Abstract
This paper deals with the adsorption of heavy metal ions (Cu2+ and Zn2+) on the carbonaceous materials obtained by chemical activation and ammoxidation of Polish brown coal. The effects of phase contact time, initial metal ion concentration, solution pH, and temperature, as well as the presence of competitive ions in solution, on the adsorption capacity of activated carbons were examined. It has been shown that the sample modified by introduction of nitrogen functional groups into carbon structure exhibits a greater ability to uptake heavy metals than unmodified activated carbon. It has also been found that the adsorption capacity increases with the increasing initial concentration of the solution and the phase contact time. The maximum adsorption was found at pH = 8.0 for Cu(II) and pH = 6.0 for Zn(II). For all samples, better fit to the experimental data was obtained with a Langmuir isotherm than a Freundlich one. A better fit of the kinetic data was achieved using the pseudo-second order model.

Abstract
Eighty percent of the world's wastewater is discharged back into nature without reuse and further treatment and solid byproduct of wastewater is either spread on land or landfilled. The valorization of municipal sewage sludge for energy use is a major opportunity for sustainable energy applications. This includes effective dewatering and drying of the sludge in addition to producing biogas during the anaerobic digestion. Supercritical CO 2 extraction process was investigated for the purpose of drying municipal sewage sludge. Remarkably our results showed that after sCO2 processing the higher heating value (HHV) of sludge at wet basis moisture content of 52% was 14 MJ/kg and thus higher than the HHV of brown coal with similar moisture level (12 MJ/kg). Our research also shows that under specific conditions sCO2 extraction reduces the moisture content of the municipal sludge from 89% to 53% in 15 min. Although, more research is needed this dewatering process could be considerably less energy intensive than conventional thermal and other drying processes. Another benefit is extraction of micro pollutants by sCO2 treatment and thus making the dried sludge more useable in energy applications as per regulations. Our results show an alternative and novel pathway for highly effective dewatering and drying of municipal and other types of sludge.

Abstract
BACKGROUND It has been previously found that humic substances (HSs) can serve as the environmentally benign non-toxic agent for the preparation of magnetic and noble metals nanoparticles that are increasingly used in biomedicine. The structure of HSs and, hence, their synthetic potential depend on the source of their origin. Thus, humification character, determined by conditions and duration of complex transformation of organic remains in HSs can evidence their structure, in particular their aromaticity and oxidation degree. The incorporation of platinum nanoparticles in a shell of HSs allows obtaining aggregate-stable nanomaterials with directly controlled structural and nanomorphological characteristics, which combine the properties of platinum nanoparticles (selective cytotoxicity, anti-inflammatory activity, etc. And a complex of biological properties of HSs (antioxidant, immunomodulatory and anti-inflammatory activity. At the same time, the expression of valuable properties of platinum nanoparticles can be varied directly by changing their nanomorphological characteristics that strongly depend on the conditions of synthesis, in particular on the HSs type which is used for the synthesis. AIM To study the effect of humification (aromaticity and oxidation degree) of three types of humic substances extracted from natural Mongolia sources (therapeutic muds of Gurvan Nuur Lake, brown coal of Baganuur coal deposit and shale of Shine Hudag deposit) on structural and nanomorphological characteristics of Pt0-containing nanocomposites produced on their basis. METHODS Nanocomposites with Pt0 content 1.2-6.5% were synthesized by reduction of hydrogen hexachloroplatinate with HSs in an aqueous-alkaline medium upon heating (90 °C). The yield of nanocomposites varied depending on type of HSs in the range 75-96%. The structure, composition and morphology of obtained nanocomposites were characterized by complex of modern physical and chemical methods (elemental analysis, XRD, SEM, TEM, IR- and optical-spectroscopy, DLS). RESULTS The platinum-containing nanocomposites have been synthesized using the reduction and stabilizing potentials of HSs with different degrees of humification (aromaticity and oxidation degree) and isolated from three natural Mongolian sources. The effect of functional composition, including oxidation and aromaticity degrees of HSs on the yield, quantitative and nanomorphological characteristics of produced platinum nanocomposites has been found. It is established that under the same reaction conditions platinum nanoparticles with face-centered cubic lattice and the smallest average size (9-15 nm) are formed from humic substances extracted from coal, while HSs derived from mud and shale afford the nanoparticles of larger size (18-28 and 16-26 nm respectively). The increase of platinum content in nanocomposites enlarges their average size, decreases their aggregate stability, as well as augments oxidation degree of HSs macromolecules. The reduction of platinum from precursor to the zero-valent state occurs due to oxidation of the phenolic and alcoholic hydroxyl groups, which are major components of HSs, as well as carbonyl groups. At the same time, HSs cover individual platinum nanoparticles, making them water soluble and preventing their aggregation. CONCLUSION Thus, we have synthesized a series Pt0-containing nanocomposites containing 1.2-6.5% with use as reducing and stabilizing matrix of natural available HSs with different humification characteristics (aromaticity and oxidation degree) and isolated from three natural Mongolia sources It is found that obtained nanocomposites are formed in form of platinum nanoparticles mainly of spherical shape and size of 3-42 nm distributed in a matrix of HSs. Polyfunctional composition of HSs is determined by conditions of their transformation and degree of humification, which provides their reducing and stabilizing properties during the synthesis of platinum metallic nanocomposites. It is established that Pt0 nanoparticles with the smallest average size and the highest aggregate stability are generated from HSs-coal with the lowest oxidation degree. These data contribute significantly to understanding of possible control of the nanomaterials synthesis and prediction of their properties.
