  • Industrial ceramic of Korean industrial design, especially tableware show different characteristics in their forms between 1940s-1960s, and 1970s-1990s. The shift of such changes can be verified objectively by module measurement. The validity of the results applying this method is supported by the investigation of the change of aesthetic modes in Korean society. The most obvious change in the figurative characteristics of tableware is in the outline of their external shapes. 'Module' is used to describe and analyze the changes of such an external shape more strictly as the objective method and measuring the module is employed. This method was developed by the combination of the method analyzing figurative art works by Re Corbuise who uses 'module' with Hambidge's method to describe and analyze the works by means of the golden section. The shift of flgurative changes of tableware could be examined objectively and elaborately by such a newly developed method. The industrialization of tableware production in Korea was begun in 1940s. Then its design was not activated, but as the society has been stabilized through the liberation and civil war, design was settled in 1960s. After that, the design has played the essential roles in 1970s. And as the importance of design in producing goods has been recognized according to the economic growth. The design of tableware shows a remarkable difference based on 1960s and 1970s in such an economic growth. It is resulted from the scientific data analysis of the design since 1940 without any preference. According to the results which analyze the external shapes of tableware for last 50 years, the tableware designs show much differences between 1940s-1960s, and 1970s-1990s. The figurative changes of Korean tableware show the similar trends to the transitional aspects of the society. Design is the manifestation of aesthetic modes which have been developed in a close relationship to society and especially economy. In Korea the development of design was initiated by the economic growth and the Korean aesthetic modes were also changed with the economic growth. The transitional shift of aesthetic modes shown in the figurative characteristics of tableware which are divided on the basis of 1960s and 1970s was peak in 1970s with the development of economy and design started in 1960s.

  • Active search for lead-free piezoceramics over the last decade has harvested a considerable amount of achievements both in theory and in practice. Few would deny that those achievements are highly beneficial, but agree that this quest of developing the lead-free piezoceramics in replace for PZTs is successfully completed. Nevertheless, few would clearly state where this quest should be directed in our next move. A source of this uncertainty may originate from the fact that it is still not clear how good is good enough to beat PZTs. In this short review, we analyzed the existing literature data to clearly locate the current state of the art of lead-free piezoceramics in comparison to PZT-based piezoceramics. Four strategies of a potential importance were suggested and discussed to help researchers plan and design their future research on lead-free piezoceramics with a recently reported exemplary work.

  • Continued miniaturization and increasingly exact requirements for thin film deposition in the semiconductor industry is driving the search for new effective, efficient, selective precursors and processes. The requirements of defect-free, conformal films, and precise thickness control have focused attention on atomic layer deposition (ALD). ALD precursors so far have been developed through a trial-and-error experimental approach, leveraging the expertise and tribal knowledge of individual research groups. Precursors can show significant variation in performance, depending on specific choice of co-reactant, deposition stage, and processing conditions. The chemical design space for reactive thin film precursors is enormous and there is urgent need for the development of computational approaches to help identify new ligand-metal architectures and functional co-reactants that deliver the required surface activity for next-generation thin-film deposition processes. In this paper we discuss quantum mechanical simulation (e.g. density functional theory, DFT) applied to ALD precursor reactivity and state-of-the-art automated screening approaches to assist experimental efforts leading toward optimized precursors for next-generation ALD processes.

  • Inorganic pigments have been received a great attention for various applications including paint, glazed ceramic ink, art tile, and building exterior due to their excellent thermal and chemical stability. Traditionally, the compositions of $PbCrO_4$, CdS and CdSe have been widely used as a yellow inorganic pigment. However, the use of these compositions has been restricted in recent years, because they contain harmful elements such as Cd, Cr, Pb and Se. In this study, new environment-friendly ceria-based pigment was synthesized using solid state reaction. Crystal structure and morphology of the obtained $Ce_{1-x}Zr_xBi_yO_{2-y/2}$ yellow pigment were analyzed using XRD and SEM, respectively. Substitutional effect of Zr and Bi on the pigment color was analyzed using UV-vis. spectrophotometer and CIE $L^*a^*b^*$ analysis. The crystal structure of the obtained pigments was dependent on the calcination temperature. The color characteristics and absorption band of the pigments were dependent on the calcination temperature and Zr, Bi contents. As a result, all the obtained yellow pigments showed the effective absorption ranged from ultraviolet to visible light, and $Ce_{0.44}Zr_{0.36}Bi_{0.20}O_{0.19}$ (x = 0.36, y = 0.20) pigment showed the most brilliant yellow color.

  • The lead-based perovskite (CH3NH3PbI3) material has a high molar coefficient, high crystallinity at low temperature, and long range of balanced electron-hole transport length. In addition, PCE of perovskite solar cells (PSCs) has been dramatically improved by over 22% by amending the electronic quality of perovskite and by using state-of-the-art hole transporting materials (HTMs) such as tetrakis(N,N-di-p-methoxyphenylamine)-9,9'-spirobifluorene (spiro-OMeTAD) due to enhanced charge transport toward the electrode via properly aligned energy levels with respect to the perovskite. Replacing the spiro-OMeTAD with new HTMs with the desired properties of appropriate energy levels, high hole mobility in its pristine form, low cost, and easy processable materials is necessary for attaining highly efficient and stable PSCs, which are anticipated to be truly compatible for practical application. Furthermore, Recently Pb-free perovskite materials much attention as an alternative light-harvesting active layer material instead of lead based perovskite in photovoltaic cells. In this work, we demonstrate a Pb-free perovskite material for the light harvesting and emitter as optoelectronic devices.
