일반적으로 박물관이라 하면 수집된 고고학적 또는 역사적 유물이나 미술작품과 같은 예술품 등 을 박물관이라는 건축물에 전시실을 두고 습도나 조도 등을 맞추어 일반 대중에 단순히 보여주는 전시시설로 생각할 수 있다. 국제박물관협의회(ICOM : International Council of Museum)의 정관과전문직원윤리강령(Code of Professional Ethics, 1986)의하면,“ 박물관은사회와사회의 발전에 이바지하고, 공중에게 개방되는 비영리의 항구적인 기관으로서, 학습과 교육, 위락을 위해 서, 인간과 인간의 환경에 대한 물질적인 증거를 수집,...

We demonstrated an effective way of preparing melt spinnable mesophase pitches via catalytic hydrogenation of petroleum residue (fluidized catalytic cracking-decant oil) and their subsequent thermal soaking. The mesophase pitches thus obtained were analyzed in terms of their viscosity, elemental composition, solubility, molecular weight, softening point and optical texture. We found that zeolite-induced catalytic hydrogenation under high hydrogen pressure contributed to a large variation in the...

Global warming is rapidly becoming a major concern as a result of the continuing emissions of greenhouse gases generated by the combustion of fossil fuels. To resolve this problem, various studies on efficient energy storage devices have been undertaken. Electronic technologies are increasingly used in electronic products and systems, and they require effective energy storage [1,2]. Supercapacitors are energy storage devices with high power density and long cycle life, and have been spotlighted...

Carbon fibers (CFs) have a unique combination of outstanding mechanical, physical, and chemical properties and are among the materials most frequently used in the preparation of a large variety of composites [1-5]. CF-reinforced polymer composites have been widely used in many advanced technological fields, such as aerospace, engineering, sporting goods, automobiles, and marine industry during the past few decades due to their excellent properties, including high strength-to-weight ratios, light...

Fiber reinforced composites are being used in the automotive industry and other manufacturing fields. Their properties, including high specific stiffness, strength and weight reduction make fiber composite materials an attractive replacement for metal components. The development of composites like carbon fiber reinforced plastic and related production technologies have contributed to the increasing application of fiber composite materials. Many new components have recently been adapted,...

We have demonstrated the production of thin films containing multilayer graphene-coated copper nanoparticles (MGCNs) by a commercial electrodeposition method. The MGCNs were produced by electrical wire explosion, an easily applied technique for creating hybrid metal nanoparticles. The nanoparticles had average diameters of 10?120 nm and quasispherical morphologies. We made a complex-electrodeposited copper thin film (CETF) with a thickness of 4.8 μm by adding 300 ppm MGCNs to the electrolyte...

Isotropic pitch-based fibers produced from coal tar pitch with the melt-blowing method were carbonized at temperatures ranging from 800 to 1600oC to investigate their crystalline structure and physical properties as a function of the carbonization temperature. The in-plane crystallite size (La) of the carbonized pitch fiber from X-ray diffraction increased monotonously by increasing the carbonization temperature resulting in a gradual increase in the electrical conductivity from 169 to 3800...

A drop weight impact test was conducted in this study to analyze the mechanical and thermal properties caused by the changes in the ratio of carbon fiber reinforced plastic (CFRP) to ethylene vinyl acetate (EVA) laminations. The ratios of CFRP to EVA were changed from 10:0 (pure CFRP) to 9:1, 8:2, 6:4, and 5:5 by manufacturing five different types of samples, and at the same time, the mechanical/thermal properties were analyzed with thermo-graphic images. As the ratio of the CFRP lamination was...
