A technology for fabricating solid-state targets from 10B-enriched powder by free sintering under reduced pressure has been developed. Nanoparticles were synthesized via femtosecond laser ablation in liquid. The influence of the sintering conditions of the targets on the productivity of the process and the characteristics of the resulting nanoparticles was investigated. Colloidal solutions of nanoparticles with average sizes of 50–60 nm and a narrow size distribution were obtained. It was found that optimizing the sintering parameters allows for a twofold increase in the productivity of the laser ablation synthesis. The results demonstrate the potential of the developed approach for producing elemental boron-10 nanoparticles required for effective boron neutron capture therapy.","PeriodicalId":585,"journal":{"name":"Inorganic Materials","volume":"61 7-15","pages":"643 - 648"},"PeriodicalIF":0.7,"publicationDate":"2026-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147968124","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}

Their surface has been modified with organic radicals derived from fatty acids: stearic and oleic (18:0 and 18:1n-9cis, respectively). IR spectra of the synthesized xerogels contain characteristic peaks of silica and, after modification, those of organic molecules adsorbed on the xerogel surface. Analogous investigation has been carried out for silica aerogel. We have studied structural and surface properties of the xerogels and compared them to those of the aerogel. The results demonstrate that the specific surface area of all the materials studied is below 500 m2/g, but the aerogel has a larger pore diameter and its pore diameter distribution is shifted toward macroscopic pores, whereas a mesoporous structure prevails in the xerogels prepared from nepheline. In addition, the steric factor for the surface modifiers has been shown to play an important role in adsorption on the materials we obtained. In particular, the specific surface area of the sorbent prepared via surface modification of 18:1n-9cis is 30% smaller than that of the parent xerogel, and the one of the surface-modified 18:0 is 14% smaller, which suggests that, in the former case, the access to pores is spatially blocked for the adsorbate gas in larger measure.","PeriodicalId":585,"journal":{"name":"Inorganic Materials","volume":"61 7-15","pages":"431 - 440"},"PeriodicalIF":0.7,"publicationDate":"2026-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147967969","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}

Films with various relative contents of titanium and niobium atoms are shown to be formed by varying the metal cathode evaporator currents. The films are found to have a columnar multilayered structure. The thickness of niobium-rich layers is 3–4 nm and that of titanium-rich layers, 7–35 nm. The main phase of the films is β-TiNb. The microhardness and wear parameter of the deposited films are determined. The dependence of the microhardness and wear parameter on the ratio of the metal cathode evaporator currents has been revealed. The relation between the microhardness and wear resistance of the TiNb films has been found, and it can be used to predict the behavior of the material under operating conditions.","PeriodicalId":585,"journal":{"name":"Inorganic Materials","volume":"61 7-15","pages":"550 - 555"},"PeriodicalIF":0.7,"publicationDate":"2026-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147967977","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 resin has been used to prepare a thermally stable epoxyimide composite with flame-retardant properties. The amount of the curing agent has been optimized using thermogravimetry: from weight loss data. The optimal amount of the curing agent in the epoxyimide composite has been determined to be 20 parts by weight for 100 parts by weight of the resin. The curing process requires no cure accelerator and occurs in the temperature range 56–128°C. Under optimal cure conditions, the degree of cure reaches 96%. The thermal properties of the epoxy composite and related coatings have been studied by differential thermal analysis and derivative thermogravimetry, and some of their physicomechanical properties have been investigated.

Comprehensive mechanical testing, including tensile behavior and elongation at break, was conducted to assess the influence of nanoparticle addition on the functional performance of the composites. The introduction of nickel oxide nanoparticles markedly enhanced the thermal stability of the hybrid systems relative to the unmodified blend. This effect is attributed to improved phase compatibility and stronger interfacial interactions between the nanoparticles and the polymer phases. AFM observations further revealed that even a minimal nanofiller loading (1.0 wt %) serves as an efficient nucleating agent, stimulating the formation of a fine, highly ordered spherulitic microstructure.

A mechanical mixture of polypropylene with 30 wt % butadiene-styrene copolymer was used as a thermoplastic elastomer. To improve the technological compatibility of the mixed components of the mixture, a compatibilizer was used, which was modified with 1.5 wt % maleic anhydride content. The content of fibrous basalt in the composition of the thermoplastic elastomer varied within the range of 5.0–20 wt %. It was shown that for composites with 5.0–15 wt % fibrous basalt content, the first-order phase transition occurs at a temperature of 159°C. For a sample with 20 wt % fibrous basalt content, the value of this indicator increases to 168°C. Based on the data of dilatometric curves constructed in the temperature range of 20–210°C, a decrease in the specific volume or an increase in the density of composites with an increase in the content of fibrous basalt was recorded. Only at 20 wt % filler content did the specific volume increase in this temperature range. By extrapolating the dilatometric curves to the region of absolute zero (–273°C) for composites with different fiber filler contents, the “occupied” specific volume was found. This made it possible to construct a dependence of the “free” specific volume on temperature. At the temperature of the first-order phase transition, i.e. from a viscous-flowing to a solid state, the mechanism and kinetic regularities of crystallization were studied in Kolmogorov–Avrami coordinates under the condition of continuous formation of nucleation centers. It was established that in filled thermoplastic elastomers the isothermal crystallization process proceeds according to the linear (rod-like) type of growth of crystalline formations.","PeriodicalId":585,"journal":{"name":"Inorganic Materials","volume":"61 7-15","pages":"335 - 340"},"PeriodicalIF":0.7,"publicationDate":"2026-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147967979","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}
