Résumé :
A mixture of abramis brama (freshwater bream), carassius carassius (crucian carp), and sander lucioperca (pike perch) scales was used for the preparation of fish scale powder containing constituents of organic and inorganic nature. The mixture of the mentioned fish scales was washed, dried, and ground for the preparation of fish scale powder. Vibration sieving was used to prepare fish scale powder enriched with inorganic components. According to thermal analysis data, this fish scale powder enriched with inorganic components included about 36.5 wt.% components removed when heating, primarily those of organic nature, and 63.5 wt.% mineral components. Inorganic powders consisting of hydroxyapatite and magnesium whitlockite were obtained via heat treatment of this fish scale powder at 800–1000 °C. Particles of these inorganic powders consisted of sintered grains with dimensions less than 100 nm after heat treatment at 800 °C, less than 200 nm after heat treatment at 900 °C, and 100–1000 nm after heat treatment at 1000 °C. Fish scale powder enriched with inorganic components as well as heat-treated inorganic powders consisting of hydroxyapatite and magnesium whitlockite can be recommended for the production of different materials, such as ceramics or composites.

Biocomposites ́ properties are influenced by both particulate constituent characteristics. In last decades, the growing trend in using of plant fibres as filler and / or reinforcing material into biocomposites for building application is due to their renewability and environmentally friendly properties. Inorganic powdered binder substances, mainly Portland cement and/or hydraulic lime are used as matrix material in bio fibres reinforced composites. In this paper, the important characteristics of fibrous and isometric particles affecting the final properties of hardened composites will be discussed.

Résumé :
Abstract. Aerosol liquid water (ALW) is ubiquitous in ambient aerosol and plays an important role in the formation of both aerosol organics and inorganics. To investigate the interactions between ALW and aerosol organics during haze formation and evolution, ALW was modelled based on long-term measurement of submicron aerosol composition in different seasons in Beijing. ALW contributed by aerosol inorganics (ALWinorg) was modelled by ISORROPIA II, and ALW contributed by organics (ALWorg) was estimated with κ-Köhler theory, where the real-time hygroscopicity parameter of the organics (κorg) was calculated from the real-time organic oxygen-to-carbon ratio (O∕C). Overall particle hygroscopicity (κtotal) was computed by weighting component hygroscopicity parameters based on their volume fractions in the mixture. We found that ALWorg, which is often neglected in traditional ALW modelling, contributes a significant fraction (18 %–32 %) to the total ALW in Beijing. The ALWorg fraction is largest on the cleanest days when both the organic fraction and κorg are relatively high. The large variation in O∕C, from 0.2 to 1.3, indicates the wide variety of organic components. This emphasizes the necessity of using real-time κorg, instead of fixed κorg, to calculate ALWorg in Beijing. The significant variation in κorg (calculated from O∕C), together with highly variable organic or inorganic volume fractions, leads to a wide range of κtotal (between 0.20 and 0.45), which has a great impact on water uptake. The variation in organic O∕C, or derived κorg, was found to be influenced by temperature (T), ALW, and aerosol mass concentrations, among which T and ALW both have promoting effects on O∕C. During high-ALW haze episodes, although the organic fraction decreases rapidly, O∕C and derived κorg increase with the increase in ALW, suggesting the formation of more soluble organics via heterogeneous uptake or aqueous processes. A positive feedback loop is thus formed: during high-ALW episodes, increasing κorg, together with decreasing particle organic fraction (or increasing particle inorganic fraction), increases κtotal, and thus further promotes the ability of particles to uptake water.

Résumé :
Inorganic-organic hybrids (M–O–PDMS hybrids) have been synthesized from silanolterminated polydimethylsiloxane (PDMS) and inorganic sources of Al(O–sec–C4H9)3, Ti(OC2H5)4, and Ta(OC2H5)5. The molar ratio of M(OR)n/PDMS and the inorganic component derived from the different metal alkoxides were found to influence the structure and mechanical properties of the hybrids. Differential scanning calorimetry (DSC) measurements showed that the interaction between the inorganic component and PDMS increased in the order Al–O–PDMS < Ta–O–PDMS < Ti–O–PDMS hybrid. The stress-strain experiments revealed that the mechanical properties of the M–O–PDMS hybrids differed by the inorganic component, reflecting the network structure and strength of the interaction between the inorganic component and PDMS.

The primary objectives of this research were to determine the concentration of some inorganic trace components, to evaluate the concentration levels of these in Romanian wines by daily consumption of wine and the health risk of inorganic trace components intake at these rates form Romanian wine. The results indicated that the concentration levels of inorganic components in red wine decreased in the order Zn>Mn>Cr>Cu>Ni>Pb>Co>Cd, in case of white wine decreased in the order Zn>Mn>Cu>Cr>Ni>Pb>Co>Cd. Based on a 60-kilogram adult person, and moderate consumption of 200 milliliters of wine/day, the estimated daily intake of these inorganic components from wines was well below the daily allowance. The target hazard quotient suggests that the exposed humans would not experience significant health risks when ingesting these individual elements from daily consumption of 200 milliliters of Romanian wines/day.

Abstract. The processes of creation of fire-retardant varnish for wood consisting of a mixture of inorganic and polymeric substances are investigated in the work. It is established that the optimization of the inorganic component leads to a directional ratio of mineral acids and urea capable of effective fire protection of the material. Studies have shown that at the initial temperature of gaseous combustion products T = 68 °C, when exposed to the radiation panel, the untreated sample ignited after 146 s, the flame spread over the entire surface, instead, the sample fire-protected varnish did not ignite, the maximum temperature was 105 °C. In this case, as evidenced by the results of heat resistance, there is a change in the structure of the protective film of the coating. The thickness of the protective layer increases due to the decomposition of the composition, which leads to inhibition of oxidation in the gas and condensed phase, change the direction of decomposition towards the formation of non-combustible gases and combustible coke residue, reduce material combustion and increase flammability index. The coating under the influence of high temperature promotes the formation of a heat-insulating layer of coke, which prevents burning and the passage of high temperature to the material, which is confirmed by the absence of the process of ignition of fire-retardant wood. Features of braking of process of ignition and distribution of a flame of the wood processed by a varnish which consist in several aspects are established. This is the formation of a heat-insulating layer of coke, which prevents burning and the passage of high temperatures to the material, which is confirmed by the absence of the process of ignition of fire-retardant reeds. This indicates the possibility of targeted control of high temperature transfer processes to organic material through the use of special coatings for wood products.

Résumé :
This article studies inorganic components in Heliánthus tuberósus stems. Ash samples and extracts obtained at different pH values were examined. It is established that the extractant's nature has a significant effect on the yield of extractive substances from the ground stems: the greatest (45%) and the minimum (31%) yield was achieved by sodium hydroxide and distilled water, respectively. According to atomic absorption spectrometry, the main ions in the extracts obtained in different media are those of potassium, calcium, sodium, magnesium and iron. Following treatment of stems with solutions having different pH values, the mass fraction of ash varied from 0.4 to 2.3%. The smallest ash yield was observed for a stem sample after acid extraction. According to energy dispersive X-ray fluorescence spectrometry, all ash samples contained predominantly K, Ca, Si and P compounds. Acid hydrolysis produced the highest level of Si in samples, which allows this ash to be used as a silicon-containing material. The ash components of the core and outer part of the stem were compared with the initial sample. According to the nature of thermal decomposition, the initial sample and the outer shell were similar between themselves, though differing from the core. The ash content of the initial sample was 4.3%, with the ash content of the stem core being ~2 times higher than that of the outer shell (7 and 3.8%, respectively). The results of IR spectroscopy showed that splitting of bands in the IR spectra of ash samples depend on the part of the stem and the pre-treatment of raw materials at different pH values. The ash of the initial sample, core and outer shell, as well as the ash of the residues after the aqueous and alkaline hydrolysis of the stem, showed the absorption bands of carbonate groups. The IR spectra of the stem ash after acid extraction contained absorption bands characteristic of amorphous silicon dioxide. According to the conducted X-ray analysis, the studied ash samples were in an amorphous-crystal and crystalline state. The identification of phases was carried out.

Résumé :
Osteoclasts are the principal resorptive cells of bone, yet their capacity to degrade collagen, the major organic component of bone matrix, remains unexplored. Accordingly, we have studied the bone resorptive activity of highly enriched populations of isolated chicken osteoclasts, using as substrate devitalized rat bone which had been labeled in vivo with L-[5-3H]proline or 45Ca, and bone-like matrix produced and mineralized in vitro by osteoblast-like rat osteosarcoma cells. When co-cultured with a radiolabeled substrate, osteoclast-mediated mineral mobilization reached a maximal rate within 2 h, whereas organic matrix degradation appeared more slowly, reaching maximal rate by 12-24 h. Thereafter, the rates of organic and inorganic matrix resorption were essentially linear and parallel for at least 6 d when excess substrate was available. Osteoclast-mediated degradation of bone collagen was confirmed by amino acid analysis. 39% of the solubilized tritium was recovered as trans-4-hydroxyproline, 47% as proline. 10,000 osteoclasts solubilized 70% of the total radioactivity and 65% of the [3H]-trans-4-hydroxyproline from 100 micrograms of 25-50 micron bone fragments within 5 d. Virtually all released tritium-labeled protein was of low molecular weight, 99% with Mr less than or equal to 10,000, and 65% with Mr less than or equal to 1,000. Moreover, when the 14% of resorbed [3H]proline-labeled peptides with Mr greater than or equal to 2,000 were examined for the presence of TCA and TCB, the characteristic initial products of mammalian collagenase activity, none was detected by SDS PAGE. In addition, osteoclast-conditioned medium had no collagenolytic activity, and exogenous TCA and TCB fragments were not degraded by osteoclasts. On the other hand, osteoclast lysates have collagenolytic enzyme activity in acidic but not in neutral buffer, with maximum activity at pH 4.0. These data indicate that osteoclasts have the capacity to resorb the organic phase of bone by a process localized to the osteoclast and its attachment site. This process appears to be independent of secretion of neutral collagenase and probably reflects acid protease activity.

Résumé :
Kidney stone disease affects people globally, with its prevalence on the rise. Given the importance of elements’ function in formation of kidney stones, this study investigated major and trace element content in thirty kidney stone samples from patients in Beijing. The kidney stone samples included inorganic components (calcium oxalate and carbonate apatite) and organic components (uric acid). Results showed that Ca is much higher in inorganic components than organic components. Compared to inorganic components, uric acid has a very low content of elements except for Cu and Se, which may be derived from the liver. Carbonate apatite stones have a higher element content (such as Na, K, Sr, Zn, Rb, Ba, Li, and Ti) than calcium oxalate stones, especially enrichment of Mg. The principal components analysis (PCA) extracted three principal components (PCs) with total variances of 91.91%, including the PC1 (45.08%): Na-Li-Ti-Ba-Sr-Zn, PC2 (30.05%): Rb, K, Mg, and PC3 (16.78%): Cu-Se, indicating that there are co-precipitated processes of these elements by their specific properties. A different distribution of stone types in the three components indicates a significant discrepancy in their element content, which can be an essential reference for patient intake elements.

Résumé :
The distribution of about twenty inorganic elements was traced in the skeletons of black corals of the Antipathes salix species. Electron microprobe and PIXE mappings revealed the peculiar structure of this material, composed of the large cells (arranged in annual rings), surrounded by thin layers with an elevated level of iodine (up to 5%). Our current knowledge of the chemical composition of these corals’ skeleton is not complete. Essentially the organic skeleton is saturated with inorganic elements and several of these could be commercially important. In fact, they have never been investigated for biomedical applications. In this preliminary current work, black corals from the Antipathes salix species were studied with the aim of detecting the inorganic components of their matrix and their suitability as biomedical materials.

Résumé :
Abstract. In this study, the fuzzy analytic hierarchy process (AHP) is used to study the relationship between drinking water quality based on content of inorganic components and landform classes in the south of Firozabad, west of Fars province, Iran. For determination of drinking water quality based on content of inorganic components, parameters of calcium (Ca), chlorine (Cl), magnesium (Mg), thorium (TH), sodium (Na), electrical conductivity (EC), sulfate (SO4), and total dissolved solids (TDS) were used. It was found that 8.29 % of the study area has low water quality; 64.01 %, moderate; 23.33 %, high; and 4.38 %, very high. Areas with suitable drinking water quality based on content of inorganic components are located in parts of the south-eastern and south-western parts of the study area. The relationship between landform class and drinking water quality based on content of inorganic components shows that drinking water quality based on content of inorganic components is high in the stream, valleys, upland drainages, and local ridge classes, and low in the plain small and midslope classes. In fact we can predict water quality using extraction of landform classes from a digital elevation model (DEM) by the Topographic Position Index (TPI) method, so that streams, valleys, upland drainages, and local ridge classes have more water quality than the other classes. In the study we determined that without measurement of water sample characteristics, we can determine water quality by landform classes.

Résumé :
Abstract In this study, we have examined how the activation of hydrothermally carbonized sewage sludge and horse manure influences the inorganic component of these materials and surface chemistry. This was examined through statistical correlations between kinetic tests using trimethoprim, fluconazole, perfluorooctanoic acid, and copper, zinc, and arsenic and physicochemical properties. Yield and inorganic content varied considerably, with potassium hydroxide–activated materials producing lower yields with higher inorganic content. Phosphoric acid activation incorporated inorganically bound phosphorus into the material, although this showed no statistically relevant benefit. A maximum surface area of 1363 m2g−1 and 343 m2g−1 was achieved for the horse manure and sewage sludge. Statistical analysis found positive correlations between carbon-oxygen functionalities and trimethoprim, fluconazole, perfluorooctanoic acid, and copper removal, while inorganic content was negatively correlated. Conversely, arsenic removal was positively correlated with inorganic content. This research provides insight into the interactions with the organic/inorganic fraction of activated waste materials for water treatment.

Résumé :
The possibilities of improving starch/water batter foam properties by additions of inorganic and organic compounds, waste sawdust and waste paper pulp were investigated. The most suitable ratio between starch and water was set to 2:3. The best results were obtained when calcium stearate was added to the starch/water tray because it filled the matrix of the tray and improved the surface. The addition of calcium stearate and a low amount of waste paper pulp and/or waste sawdust also brought good results. Higher amounts of waste sawdust and calcium stearate did not produce the compact and smooth surface of starch trays. The addition of polyvinyl alcohol improved these parameters. &nbsp;
