The Republic of Türkiye will celebrate its centennial, the Turkish Naval Academy (TNA) will celebrate its quarter-millennial, and the Journal of Naval Sciences and Engineering (JNSE) will celebrate its vicennial in 2023. Undoubtedly, the historical intersection is a source of praise and pride for our academy and for our journal. \u0000 \u000099 years ago, the Turkish nation created an epic of independence under the leadership of Gazi Mustafa Kemal Atatürk and his comrades in the War of Independence. The 100th anniversary of the Republic will be celebrated in 2023 to cherish the deep-rooted memory of our struggle for independence. \u0000 \u0000Founded in 1773 by Mustafa III, the 26th Sultan of the Ottoman Empire, the Imperial School of Naval Engineering (Mühendishane-i Bahr-i Hümâyûn), considered the first engineering school of the Empire, became the foundation of both the TNA and the Istanbul Technical University (ITU). TNA and ITU have special positions in terms of Turkish modernization history as the institutions where engineering and technical education have continued since the Ottoman period with their 249 years of distinguished history. 2023 will mark these exceptional institutions’ 250th anniversary. \u0000 \u00002023 will also mark the 20th anniversary of the international journal of the TNA, i.e., JNSE. The journal aims to provide a scientific contribution to the theory and applications of naval sciences and engineering and share knowledge in relevant fields since its first issue in 2003. \u0000 \u0000As we are entering this historically significant year, it is an honor and privilege for me to have been appointed as the Editor-in-Chief (EIC) of the scientific journal of our prestigious 250-year-old academy. As an Editorial Board Member since 2013, as well as an Editor in both 2018 and 2019, and as an Administrative Board Member of the Naval Sciences and Engineering Institute from 2013 to 2022, I have seen the continued improvement that JNSE has experienced. I inherit the role of Editor-in-Chief of the JNSE at a special time when our journal has been included within the scope of the ULAKBIM TR Index. \u0000 \u0000The journal must, first and foremost, continue to provide a contribution to science and engineering in fields aligned with the areas of interest of the JNSE, e.g., electrical and electronics engineering, naval/mechanical engineering, naval architecture and marine engineering, industrial engineering, computer science and engineering, and basic/social sciences. In the meantime, we will do our best to make our journal ready to be a candidate to be indexed in Science Citation Indexes. Raising the quality of the accepted papers by introducing strict review criteria will be instrumental in achieving this goal by increasing the impact of the journal. \u0000 \u0000To this end, we recently applied to join Crossref as a member under the sponsorship of TUBITAK ULAKBIM DergiPark, and consequently, the JNSE will be ","PeriodicalId":413796,"journal":{"name":"Journal of Naval Sciences and Engineering","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131176327","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}

In this study, non-aqueous-based tape casting of alumina was carried out in a non-continuous single blade tape casting machine. A slurry, dependence on the alumina powder in a solvent with additives like binders, , plasticizers and dispersants was cast on a stationary surface. After the green strips were freed, they were sintered to obtain the final desired shape. Hyraulic pressing method was used to optimize the microstructure and increase the density of the alumina green tapes. Layered alumina ceramics were produced at 5 different temperatures by pressureless sintering method (1450°C, 1500°C, 1550°C, 1600°C and 1650°C) for 5 h to observe the effect of sintering temperature on the microstructure. Results revealed the sintering conditions for obtaining translucent alumina, with the utilized slurry composition.","PeriodicalId":413796,"journal":{"name":"Journal of Naval Sciences and Engineering","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128721176","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}
