Due to global warming, an electrochromic smart window which is effective for energy saving has been gaining a lot of attention. However, high production cost and durability issues are limiting its widespread use. Various studies have been conducted on counter electrode and electrolyte materials to improve electrochromic performance and durability as well as productivity. In addition, research on optimizing the device structure through the passivation layer and on film-type electrochromic devices using flexible substrates have also been conducted. These recent research results are expected to enable the global distribution of smart windows.","PeriodicalId":9738,"journal":{"name":"Ceramist","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82308343","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}

Therefore, eco-friendly and lead-free halide perovskites (EHPs), which are superior to LHPs, should be developed.

To endow glass with such a foldability, while keeping its merits over polymeric materials, tons of complicated issues need to be resolved in addition to thickness reduction. Since UTG is subjected to repeated deformations during its service as a flexible cover window, extra care is required to minimize microcracks during the whole preparation process. Here, it is noteworthy that chemical strengthening via ion exchange should be performed to UTG for better durability. In this article, after briefly reviewing the current status of UTG in terms of production and process, its chemical strengthening is highlighted as a viable option to further innovate its functionalities. A new ion-exchange technique which is not adopting the molten-salt-bath is proposed, and some experimental demonstrations exemplifying the concept of ‘actively stress-managed glass’ are delineated.","PeriodicalId":9738,"journal":{"name":"Ceramist","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75376461","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}

There is another type of waste glass recently emerged, namely, display waste glass derived from LCD and OLED industry. There are three main sources where the waste glass is generated: 1) LCD/OLED glass manufacturers, 2) LCD/OLED panel manufacturers and 3) end-of-life LCD/OELD devices. Both first and second sources are the onsite manufacturing of LCD/OLED glass or panels in four Asian countries. Whereas, the third one is anywhere LCD/OLED devices are used. Therefore, the disposal of the end LCD/OLED waste glass from the third source is not a local but a global issue. In the present paper, the recycling possibility of such waste glass is reviewed based on literatures and their results are discussed from the viewpoint of valuable recycling.","PeriodicalId":9738,"journal":{"name":"Ceramist","volume":"52 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82260836","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}

Especially, the increasing demands for high alloy steels production and high speed casting reveals serious contradiction between two principal functions of mold flux: lubrication and controlling heat transfer. In order to overcome this problematic needs, some innovative research activities are being carried out. MAE (Mixed Alkali Effect) has been examined in alumino-borosilicate-based mold system to stabilize alkali cation and aluminum association, which enables chemically stable glassy mold flux film during casting of high alloy steels. Non-Newtonian mold fluxes could be developed by addition of Si3N4 or SiC due to the increase of stiffness of polymeric structure, which would be beneficial to satisfy the contradictory requirements of viscosity at mold top surface and mold wall. Some innovative ideas for controlling mold heat transfer without deteriorating the lubrication have been examined by dispersion of nano-size metallic particles and by modification of prenucleation motif. All these trials are closely related with glass science and engineering. Therefore, it should be highly beneficial to enhance the collaborative research activities between glass and metallurgy society for further development of advanced functional mold flux systems.","PeriodicalId":9738,"journal":{"name":"Ceramist","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74157550","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}

Due to these advantages, NiO is widely used in various industrial fields such as gas sensors. In this paper, various synthesis methods of NiO will be briefly reviewed.

The regioselective confinement effect of small-pore, cage-type zeolites on hydrocarbon pool intermediates results in strong shape selectivity determining the product olefin distribution. Despite decades of effort, a direct correlation between zeolite cage topologies and olefin selectivity distributions had remained elusive. The cage-defining ring theory is the first general catalytic shape selectivity theory that can predict the selectivity distribution of product light olefins from the given crystallographic information of the small pore zeolite catalysts. This article outlines the development procedure of the cagedefining ring theory.

The physical and chemical characteristics of the catalyst were analyzed using field emission scanning electron microscopy, X-ray diffractometry, electrochemical impedance spectroscopy, etc. It was observed that the surface area of NiCoS, the sulfur content, and hydrogen evolution reaction activity of NiCoS increased together as the off time increased at a constant on time.
