<P>In this work, we propose a general template-free strategy for fabricating two-dimensional mesoporous mixed oxide nanosheets, such as metal cobaltites (MCo2O4, M = Ni, Zn) through the self-deconstruction/reconstruction of highly uniform Co-based metal glycerate nanospheres into 2D Co-based metal glycerate/hydroxide nanosheets, induced by the so-called “water treatment” process at room temperature followed by their calcination in air at 260 °C. The proposed ‘self-deconstruction/reconstruction’ strategy is highly advantageous as the resulting 2D metal cobaltite nanosheets possess very high surface areas (150-200 m<SUP>2</SUP>g<SUP>−1</SUP>) and mesoporous features with narrow pore size distribution. In addition, our proposed method also enables the crystallization temperature to achieve pure metal cobaltite phase from the precursor phase to be lowered by 50 °C. Using the 2D mesoporous NiCo2O4nanosheets as a representative sample, we found that they exhibit 6-20 times higher specific capacitance and greatly enhanced capacitance retention compared to the NiCo2O4nanospheres achieved through the direct calcination of the Ni-Co glycerate nanospheres. This highlights another advantage of the proposed strategy for enhancing the electrochemical performance of the mixed oxide products for supercapacitor applications. Furthermore, the asymmetric supercapacitor (ASC) assembled using the 2D NiCo2O4nanosheets//graphene oxide (GO) exhibits a maximum energy density of 38.53 W h kg<SUP>−1</SUP>, while also showing a high capacitance retention of 91% after 2000 cycles at 5 A g<SUP>−1</SUP>. It is expected that the proposed general method may be extended to other transition metal elements for creating 2D mixed oxide nanosheets with enhanced surface areas and improved electrochemical performance.</P>

Investigation on the Dispersion Characteristics in Optical Fiber Telecommunication

Ni Yan Rong,Min Ru 보안공학연구지원센터 2015 International Journal of Future Generation Communi Vol.8 No.4

Dispersion is widely existed in the optical fiber. The reason is various, such as material dispersion, waveguide dispersion, mode dispersion, and so on. It will lead to the signal waveform distortion and pulse broadening and then limit the transmission capacity and bandwidth in the optical fiber. With the rapid development, transmission rate can reach even hundreds of Gb/s, and it may lead to many problems. Correspondingly, compensation methods have been paid much attention, and there are also many methods proposed for the compensation. However, we should know the characteristics of the dispersion in order to get compensation algorithms with much higher efficiency. Optical fiber systems with better performance will be designed and manufactured. In this paper, appropriate methods are adopted to analyze the photonic crystal fiber. With the adjusting of the structure parameters, we can design a highly nonlinear photonic crystal fiber with different dispersion characteristics. We study the characteristics of the dispersion of optical fiber communication. According to the analysis to obtain the dispersion characteristics of optical fiber under different parameters.

MUJI 디자인의 지속가능한 생태융합적 특성에 관한 연구

판옌니(Fan, Yan Ni),송만용(Song, Man Yong) 한국전시산업융합연구원 2021 한국과학예술융합학회 Vol.39 No.4

오늘날 유엔의 SDGs프로그램에서도 볼 수 있듯이, 생태적 위기와 환경 문제는 지속 가능적 사고에 대한 관심을 증대시키고 있다. 이제 건축뿐만 아니라 디자인에서도 생태적 윤리성을 고려한 디자이너의 역할이 중요해졌다. 그래서 본 소고는 지속가능한 디자인에 주목하고자 한다. 그러나 생태학의 지속 가능적 관점은 서양의 인간 중심적이기보다는 동양철학의 인류와 자연이 조화롭게 지내는 세계 특히 선(禪)사상과 매우 밀접하다. 즉 선사상의 ‘자연무위(自然無為)’, ‘생생불식(生生不息)’, ‘유무상생(有無相生)’, ‘만물동정(萬物同情)’ 개념과 유사하기 때문이다. 더욱이 선사상은 일본의 ‘와비·사비’로 나타나게 되었고 이것이 일본디자인 특히 MUJI 디자인에 많은 영향을 주고 있다. 그리하여 본 연구의 목적은 선사상과 MUJI 디자인에 나타난 지속가능한 생태적 특성을 고찰하는 것이다. 그래서 본 연구는 먼저 문헌연구를 통해 선사상이 일본 디자인에 적용된 원인을 살펴본 뒤, 동양 선사상의 자연관과 지속가능성과의 공통점과 차이점을 비교한다. 다음으로 “와비·사비”의 특징과 지속가능한 디자인의 개념화를 시도한다. 연구결과는 다음과 같다. 첫째, 자연적인 행위에 부합하는 디자인. 둘째, 전형적인 디자인. 셋째, 폐기물을 활용한 리디자인. 넷째, 전통 민예에 근거한 디자인의 네 가지의 특성으로 제시할 수 있음을 알게 되었다. 이러한 연구결과를 바탕으로 MUJI 디자인을 넘어 인간과 생태환경, 그리고 디자인이 자연스럽게 공존하고 융합된 디자인이 확대되길 기대한다. It can also be seen from the current UN SDGs plan that ecological crises and environmental issues have increased attention to sustainable thinking. Nowadays, not only architecture, but also the role of designers who consider ecological ethics in design is becoming more and more important. Therefore, the research will focus on sustainable designing. However, the ecological sustainability view is not so much the human center of the West, as it is the world that is in harmony with the human and nature of Eastern philosophy, especially Zen thought. That is, it is similar to the concepts of “Natural inaction(自然無為)”, “life and growth in nature(生生不息)”, “Existence and nonexistence give birth to one another(有無相生)”, and “Compassion for All Things(萬物同情)” in Zen thought. In particular, Zen thought appeared in the form of Japanese “WABI·SABI”, which had a great influence on Japanese design, especially MUJI design. Therefore, the purpose of this research is to investigate the sustainable ecological characteristics of Zen thought and MUJI design. Firstly explores the reasons why Zen thought was applied to Japanese design through literature researches, and then compares the common and different points of nature view and sustainability of Oriental Zen thought, finally tries to conceptualize the character and sustainable design of “WABI·SABI”. According to the current research status, the research on the sustainable characteristics of MUJI design is not enough. The research results are as follows. This study will propose four sustainable ecological characteristics embodied in MUJI design: design that conforms to natural behavior, typical design, redesigning employing waste, and the traditional folk art design. Based on the results of such research, we look forward to the emergence of designs that go beyond MUJI design, expand the human and ecological environment, and design the coexistence and integration of nature.
