Nanocomposites containing controlled nanofiller loadings were fabricated and characterized by tensile testing and thermogravimetric analysis. Incorporation of C60/70 fullerenes yielded the most pronounced mechanical enhancement, increasing tensile strength from 31.41 to 31.87 MPa and elongation at break from 34 to 40%. MWCNTs produced moderate improvements (up to 29.77 MPa and 38%), contributing primarily to matrix stability. Thermal analysis showed that all nanofillers improved the thermo-oxidative resistance of PP. Fullerenes increased decomposition temperatures (T10 = 250°C, T20 = 300°C, T50 = 360°C), elevated τ1/2 from 63.2 to 68.8 min, and raised activation energy from 145.45 to 189.48 kJ/mol. MWCNTs similarly enhanced thermal thresholds (T10: 135 → 250°C; T20: 265 → 300°C; T50: 335 → 350°C) and extended τ1/2. Overall, C60/70 fullerenes provide dominant mechanical reinforcement, while thermal stability arises from their radical-scavenging ability combined with the structural and buffering contributions of MWCNTs and NiO. These findings offer design principles for high-performance PP-based nanocomposites.","PeriodicalId":585,"journal":{"name":"Inorganic Materials","volume":"61 7-15","pages":"612 - 618"},"PeriodicalIF":0.7,"publicationDate":"2026-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147967978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the high-temperature solid-phase synthesis method, compounds with glaserite-like structures such as nagelschmidtite and carnotite were obtained. It was established that the formation of single-phase copper-zinc-substituted silicophosphates requires synthesis at ~1500°C in an oxygen stream with preliminary calcination at 1000°C. Hydrolysis of the resulting compounds in aqueous solution provides a final pH of ~7.4–7.8, which meets physiological requirements. The solubility of these phases in a model solution of citric acid is significantly higher than that of traditional β-Ca3(PO4)2, which classifies the new materials as highly resorbable. The resulting ceramics have a density of about 80% of the theoretical value with grain sizes of 2–3 µm. The development of Cu,Zn-containing silicophosphates expands the concept of multicomponent bioceramics and offers a promising material with controlled resorption properties and improved biological activity for use in regenerative medicine.","PeriodicalId":585,"journal":{"name":"Inorganic Materials","volume":"61 7-15","pages":"373 - 383"},"PeriodicalIF":0.7,"publicationDate":"2026-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147968047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The binding and hydrophysical properties of the two-component system “MSP–Ca(OH)2” in a wide range of changes in the mass content of the mixture components were determined. IR spectra of sample compositions and electronic photographs of the chipped surface of samples after physical and mechanical testing were analyzed. It has been shown that a composition based on mechanically activated saponite-containing powder and slaked lime exhibits the properties of a cement-free binder, with the mass optimal content of mineral components (10–30% Ca(OH)2) with W/S = 0.45 allows to obtain a mixture with a compressive strength of 8–11 MPa. The maximum value of strength in a moisture-saturated state is observed with a content of Ca(OH)2 30 wt %. Increasing the concentration of calcium hydroxide above 30 wt % in the system leads to a decrease in the strength characteristics of the composite. It has been established that preliminary acid activation of saponite-containing powder leads to an increase in its pozzolanic capacity due to an increase in the content of the amorphous component, which is capable of entering into chemical interaction with lime to form needle-shaped crystals of aluminous tobermorite.","PeriodicalId":585,"journal":{"name":"Inorganic Materials","volume":"61 7-15","pages":"598 - 604"},"PeriodicalIF":0.7,"publicationDate":"2026-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147968055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have assessed the influence of biomass processing steps (HTC, carbonization, and alkaline activation), the amount of the alkaline agent, and graphene oxide (GO) additions on the physicochemical and sorption properties of the biochars. According to scanning and transmission electron microscopy data, the uncarbonized material has a disordered structure, which is determined by a considerable amount of amorphous carbon with low porosity. Carbonization opens pore spaces as a consequence of the removal of amorphous organics and formation of defects, which ensure a considerable amount of meso- and micropores. According to IR spectroscopy results, the HTC process includes active removal of thermally unstable organic compounds from the sunflower meal, and alkaline activation causes alkyl groups to appear in the composition of the material, which points to an increase in defect density in the material. These results are satisfactorily correlated with Raman spectroscopy and X-ray diffraction data. We have determined the adsorption capacity of the sunflower meal-derived biochars for Zn2+ heavy metal ions and methylene blue (MB), a synthetic organic dye. Results of comparative sorption studies in static mode show that the highest sorption capacity for Zn2+ ions and MB, 58.4 and 2301.2 mg/g, respectively, is offered by the GO-containing material. To identify the assumed adsorption mechanism, experimental kinetic data have been analyzed in terms of the pseudo-first order, pseudo-second order, Elovich, and interparticle diffusion models. The results demonstrate that Zn2+ ion and MB molecule sorption is a mixed diffusion process contributed by a pseudo-second-order reaction between the contaminant and active centers of the sorbent.","PeriodicalId":585,"journal":{"name":"Inorganic Materials","volume":"61 7-15","pages":"399 - 411"},"PeriodicalIF":0.7,"publicationDate":"2026-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147968074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These patterns are presented depending on the diameter of these elements. Taking these patterns into account, the authors developed a technology for the manufacture of multilayer microwave absorbers based on three-dimensional spiral elements made of aluminum foil. This technology involves thermopressing the construction in the form of identical fragments of a synthetic non-woven fibrous material, between which 3D spiral elements made of aluminum foil are distributed, and adhesively bonding the resulting structure to a fragment of aluminum-foiled polymer film. Absorbers manufactured in accordance with the developed technology are characterized by a wider effective absorption band (12.0 GHz) compared to similar ones. They are also flexible and lightweight. This makes them suitable for use in creating partitions for zoning anechoic chambers or for covering the walls of these chambers.","PeriodicalId":585,"journal":{"name":"Inorganic Materials","volume":"61 7-15","pages":"348 - 353"},"PeriodicalIF":0.7,"publicationDate":"2026-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147968119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
