The main goal is to optimize the SPS process for titanium carbide (TiC) ceramics, with a particular focus on the effects of insulation and die geometry (height and thickness). For the TiC material, the ideal sintering temperature is set at 2000 °C. The study analyzes eight case studies, involving a base case, an insulating case, and six cases with various thicknesses and heights, in order to evaluate the effectiveness of the suggested optimization. The results show that using insulation on the die surface reduces heat transfer from the die surface significantly, which leads to a 63% decrease in input power consumption when compared to the basic scenario. Based on a correlation study between energy and electricity, increasing die thickness raises the cross-sectional area of the electric current, which raises the amount of electric power required to attain the 2000 °C sintering temperature. The results indicate the temperature distribution in the sample is more sensitive to changes in die height than to changes in die thickness.","PeriodicalId":22113,"journal":{"name":"Synthesis and Sintering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140385843","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}

According to Photo Luminescence spectrums of both glasses there were emissions in the range of 466 and 435 nm wavelengths related to cerium ions. It was shown that by heating treatment, garnet crystal (in sulfated sample) formed less than the sample with cerium oxide. The emission spectra of both glass-ceramics, when excited at 240 nm, fall within the wavelength range of 460 nm. Also, the 534 and 660 nm emissions wavelengths were obtained by 340 nm wavelength excitation. Heat treatments were done by oxide atmosphere in tubular furnace (single step), SPS sintered powder and in hydrogen atmosphere (by two steps heating). According to XRD results the 24 hrs. heat treating time and the 1060 °C temperature affect the entry of cerium into the garnet structure. Finally, by comparing the spectroscopic results the optical response of the garnet glass-ceramic synthesized in the hydrogen atmosphere was obtained at 400 nm wavelength that indicated this garnet can be applied in the LED industry.","PeriodicalId":22113,"journal":{"name":"Synthesis and Sintering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140385899","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}

While entrapment of highly toxic yet beautiful chromophores in the spinel structure diminishes the toxicity and improves the thermal resistance, a high surface area provided by the nano-scale pigments results in a uniform bright coating with a sufficiently high color strength and enhanced light transmission. Although the spinel nano pigments are promising for the coating and ceramic industries, the applications are limited, mostly due to the required high sintering temperature. Various synthesis processes have been tried for these pigments with the sol-gel method being the most frequent one. Many elements have been considered as dopants for these spinel systems to enhance, change, or improve the optical and physical properties.

The focus is on understanding the temperature distribution during the SPS of a ZrB2 sample in a graphite die. Heat diffusion equations, augmented with Joule heating considerations, are utilized to simulate temperature variations within the system over time. Critical boundary conditions at the system's extremities are modeled as convection cooling. The Analysis of Variance (ANOVA) reveals that the diameter of the sample is the most significant factor influencing the peak temperature at the center of the ZrB2 sample. It is found that the sample diameter's variance accounts for a predominant impact on temperature, markedly more than other factors such as the die's outer diameter and sample thickness. Notably, the standard deviation of the temperature in the axial direction across all samples is less than 4 °C, a value that is statistically minor in comparison to the sintering temperatures, which are around 2000 °C. These findings are instrumental in providing an in-depth understanding of the SPS process, which is essential for the optimization of sintering parameters for ZrB2 ceramics.","PeriodicalId":22113,"journal":{"name":"Synthesis and Sintering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138966254","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}

Estrogen and aromatase play pivotal roles in hormone-responsive breast cancer, with 80% of patients exhibiting estrogen receptor-positive tumors. Aromatase inhibitors (AIs), notably non-steroidal inhibitors like anastrozole and letrozole, have significantly improved outcomes, yet challenges persist, including side effects. This review focuses on recent developments in AIs, exploring xanthone derivatives, imidazole derivatives, and curcumin derivatives as potential inhibitors of aromatase. Molecular docking studies, employing Auto Dock and other tools, reveal the binding affinities and interactions of these compounds with the aromatase enzyme. Among xanthones, Erythrommone emerges as a potent inhibitor, holding promise for clinical trials. Imidazole derivatives, synthesized through the Debus-Radziszewski reaction, demonstrate anticancer potential, with compounds like 1a exhibiting superior efficacy against MCF7 cells. ADME-Tox analyses indicate promising drug-likeness but reveal potential mutagenic effects and environmental impacts. Curcumin derivatives, particularly 1,5-diaryl-1,4-pentadien-3-ones, present alternatives to address curcumin's bioavailability challenges. A study of 25 compounds (DKC) identifies DKC-10 as a potent inhibitor, outperforming established breast cancer drugs in terms of binding affinity and interactions with aromatase and ERα+ receptors. These findings underscore the importance of exploring diverse chemical structures in developing AIs, paving the way for more effective and well-tolerated therapeutics. The integration of computational techniques, such as molecular docking studies, accelerates drug discovery by predicting interactions at the molecular level. Overall, this comprehensive review provides valuable insights into the evolving landscape of aromatase inhibitors, offering a roadmap for future research and the development of advanced breast cancer therapeutics.","PeriodicalId":22113,"journal":{"name":"Synthesis and Sintering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138607027","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}
