Experiments showed that the interaction of diisobutylaluminum hydride with acrylonitrile leads to formation of an imine adduct as well as substitution products in which the isobutyl fragment is transferred to the acrylonitrile molecule. Photopolymerization of a polymeric precursor based on the aluminoimine and 1,6-hexanediol diacrylate yielded a macroporous aluminum nitride ceramic. X-ray diffraction (XRD) and thermogravimetric analysis (TGA) confirmed formation of aluminum nitride at temperatures from 1000°C; the most intensive mass loss occurred up to 1100°C, and removal of thermolysis products of the diacrylate took place in the 300–500°C range. The significant mass loss (78%) inherent to preceramic precursors, and the associated linear shrinkage, remain problems. The substantial reduction in linear dimensions did not disrupt the macroporous structure of the printed part, however residual carbon was observed in the fired ceramic. The results demonstrate the promise of using aluminoimines and products of their oligomerization for stereolithographic ceramic fabrication; however, further study and process optimization are required to achieve lower firing shrinkage and reduced residual carbon.","PeriodicalId":586,"journal":{"name":"Inorganic Materials: Applied Research","volume":"17 2","pages":"554 - 560"},"PeriodicalIF":0.3,"publicationDate":"2026-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147743656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The addition of plasticizer and annealing of the fiberglass do not lead to significant changes in the specimens’ strength and Young’s modulus; matrix cracking does not occur during tensile testing of the composite specimens when the plasticizer content exceeds 20 wt %; pre-tensioning of the reinforcing fiber increases Young’s modulus and tensile strength of the tested specimens by 10–20%.

The sorbent materials were prepared by hydrothermal carbonization of rapeseed meal (R/HTC) (grown in the Tambov region) followed by subsequent carbonization (R/HTC/C) and alkaline activation (R/HTC/C/KOH). Post-treatment of the HTC-char enables opening of the porous space of the carbon framework due to removal of amorphous organics and the formation of defects in the material structure. The physicochemical and morphological properties were investigated by scanning electron microscopy (SEM), FT‑IR spectroscopy and Raman (vibrational) spectroscopy, and X‑ray diffractometry (XRD). Adsorption studies showed that the phenol contact time differs among the materials: for the activated material within 10 min; for R/HTC and R/HTC/C within 60 min. The experimental adsorption capacity for phenol was 298 mg/g for R/HTC, 1236 mg/g for R/HTC/C and 1309 mg/g for R/HTC/C/KOH. To determine the likely adsorption mechanism, the kinetic experimental data were analyzed using pseudo-first-order and pseudo-second-order models, the Elovich model and the intraparticle-diffusion model, while the isotherms were fitted to the Langmuir, Freundlich, Temkin and Dubinin–Radushkevich models. The kinetics for all materials are described by the pseudo-second-order equation with a contribution from diffusion-controlled phenol adsorption. The Elovich model confirms chemical heterogeneity of the R/HTC adsorbent surface. The maximum adsorption capacity from the Langmuir model was 434.8 mg/g for R/HTC, 1429 mg/g for R/HTC/C and 1667 mg/g for R/HTC/C/KOH. Parameters of the Dubinin–Radushkevich model indicate that the interaction between the adsorbent active sites and phenol is physical in nature.","PeriodicalId":586,"journal":{"name":"Inorganic Materials: Applied Research","volume":"17 2","pages":"364 - 373"},"PeriodicalIF":0.3,"publicationDate":"2026-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147743722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper presents the results of a study covering a chain of successive processes: obtaining powders of graphene-containing nanostructured composites, characterizing their phase composition and morphology, sintering the resulting compositions by hot pressing, vacuum sintering, and spark plasma sintering, and comparative analysis of the microstructure of the obtained model ceramic samples. All the resulting ceramics consisted of stoichiometric monoclinic baddeleyite ZrO2. Distinctive features of the ceramics obtained by spark plasma sintering were a high relative density of 98% and a layered grain structure. The main result of the study can be considered the fact that graphene-zirconia nanostructured powder composites synthesized by the proposed method are promising for obtaining dense fine-grained ceramics.

It has been shown that the introduction of CHA in an amount of up to 40 wt % of polymers leads to a decrease in kinematic viscosity, and the introduction of 50 wt %. СНА significantly increases it. The dependence of the dynamic viscosity of PVP gels with Alg 1 : 1 and composite gels is in the nature of pseudoplastic liquids and to a lesser extent depends on the content of CHA. Highly porous composite materials were obtained from composite gels by lyophilization. Their microstructure and porosity were studied and the average pore size was determined. It is shown that the volume fraction of pores decreases from 95 to 70% by volume and the average pore size decreases from 325 to 166 urns when adding CHA to 40 wt %. The mechanical properties of composites during compression testing are investigated. They have been shown to exhibit behavior characteristic of macroporous structures. The modulus of elasticity increases from 8 to 184 kPa with an increase in the CHA content from 10 to 50 wt % It was found that composites exhibit reversible deformation at the level of 98%.
