However, an important task is to study the toxicity of the materials used and the reaction products formed. The purpose of this study was to evaluate the impact of the proposed water treatment method on the ecosystem. Algae are excellent model organisms for studying the toxic effects of catalyst nanoparticles. This work investigates the toxicity of cobalt ferrite (CoFe2O4) and hydrogen peroxide (H2O2) on the microalgae Chlorella vulgaris Beij. (C. vulgaris). The growth rate of C. vulgaris depends on the residual concentration of H2O2, indicating a stressful physiological state of the microalgae. Exposure to sintered cobalt ferrite granules does not affect the growth of freshwater algae. At a residual H2O2 concentration of 11.9 mM, algal cells' morphology, membrane integrity, and viability were severely impaired. Hydrogen peroxide is known to cause oxidative stress, as evidenced by a decrease in the growth rate of C. vulgaris and an increase in the number of dead cells. The study showed that the high residual concentration of H2O2 is the main obstacle to the discharge of treated water into the natural ecosystem.","PeriodicalId":509433,"journal":{"name":"Physics and Chemistry of Solid State","volume":"80 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140368945","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 first reinforcement material (Al2O3) was used at a constant rate 10wt.%, while the second reinforcement material (tungsten carbide (WC) was used at different rates (0,5,10,15,20wt.%), and the base material is (Al). The three powders were ground together for two hours, and then they were poured into the mold. The compaction process was done with a hydraulic press at (5) tons for one minute. The resulting samples had green density, requiring a thermal sintering process in order to increase their durability and hardness. The sintering process was performed at 560°C for only two hours. Then, structural examinations (scanning electron microscope (SEM) and mechanical examinations (Brinell hardness, compressive strength, and wear) were performed on the sintered samples. The results showed that the best reinforcement rate was 20%, and after thermal sintering, the best Brinell hardness was 146.72 HB, with the highest compressive strength of 45.33MPa, while the lowest wear rate was 1.18×10-8g/cm.","PeriodicalId":509433,"journal":{"name":"Physics and Chemistry of Solid State","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140414774","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}

It is shown that in the range of concentrations x = 0–0.01, Al atoms mainly replace Ni atoms in the 4c position, generating acceptor states. It was established that at temperatures T = 80–160 K, the ratio of concentrations of ionized acceptor and donor states in n-Ti1-xAlxNiSn, х = 0–0.04, is unchanged, but the concentration of donors is greater. At higher temperatures, T ≥ 250 K, deep donor states that existed in n-TiNiSn as a result of \"a priori doping\" of the semiconductor are ionized. An additional mechanism for the generation of donor states in n-Ti1-xAlxNiSn when the tetrahedral voids of the structure are partially occupied by Al atoms was revealed. The concentration ratio of the generated donor-acceptor states determines the position of the Fermi level εF and the conductivity mechanisms of n-Ti1-xAlxNiSn. The studied semiconductor solid solution is a promising thermoelectric material.","PeriodicalId":509433,"journal":{"name":"Physics and Chemistry of Solid State","volume":"1 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140443440","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}
