Hearing impairment is one of the most common physical disabilities in the world. Conductive hearing loss results from dysfunction of the middle ear, and sensorineural hearing loss results from abnormalities within the cochlea or central nervous system. To improve the diagnosis of hearing loss and develop new technologies for restoration of hearing, changes of the middle ear and cochlear functions in relation to ear structural disorders in hearing impaired ears need to be characterized. This...

난청인은 난청의 정도, 종류, 유형에 따라 각기 다른 정도의 의사소통의 한계를 가질 수 있고 더 나아가 사회적인 고립, 소외감, 열등감 등의 다양한 심리적인 문제까지도 경험할 수 있다. 특히 난청아동의 경우 난청이 단순히 듣지 못함의 문제를 유발할 뿐 아니라 언어, 지각, 인지 능력 등의 저하로 연결되어 더 복합적인 문제가 유발될 수 있다. 따라서 많은 청각장애인들은 원활한 의사소통 및 사회생활을 위해 보청기라는 보조기기의 도움을 받아 소리를 증폭해 들음으로써 도움을 받으며 살아가고 있다. 하지만 고심도...

Graphite fibers are materials with a high specific modulus that have attracted much interest in the aerospace industry, but their high manufacturing cost and low yield are still problems that prevent their wide applications in practice. This paper presents a laser-based process for graphitization of carbon fiber (CF) and explores the effect of laser radiation on the microstructure of CF. The obtained Raman spectra indicate that the outer surface of CF evolves from turbostratic structures into a...

With continuous development in the field of sample preparation technology, solid phase micro-extraction (SPME) has been widely used in analytical chemistry for high extraction efficiency and convenient operation. Different materials lead to different extraction results. Among existing materials, carbon-based materials are still attracting attention from scientists due to their excellent physical and chemical properties as well as their modifiable surfaces, which could enhance the adsorption...

Carbon materials are widely used in various industry applications, such as a carbon fibers, graphite brushes, aluminum engineering and binders, because carbon materials have high specific strength, high conductivity, excellent thermal shock resistance, and other favorable properties [1-4]. These carbon materials are prepared from various precursors, such as polyacrylonitrile (PAN), phenolic resins and pitches. Among these precursors, pitches are more economical than PAN and phenol resin, and it...

In this study, magnetite (Fe3O4) nanoparticles were electrochemically synthesized in an aqueous electrolyte at a given potential of -1.3 V for 180 s. Scanning electron microscopy revealed that dendrite-like Fe3O4 nanoparticles with a mean size of < 80 nm were electrodeposited on a glassy carbon electrode (GCE). The Fe3O4/GCE was utilized for sensing chloramphenicol (CAP) by cyclic voltammetry and square wave voltammetry. A reduction peak of CAP at the Fe3O4/GCE was observed at 0.62 V, whereas...

This study synthesized pure anatase carbon doped TiO₂ photocatalysts supported on a stainless steel mesh using a sol-gel solution of 8% polyacrylonitrile (PAN)/dimethylformamide (DMF)/TiCl₄. The influence of the pyrolysis temperature and holding time on the morphological characteristics, particle sizes and surface area of the prepared catalyst was investigated. The prepared catalysts were characterized by several analytical methods: high resolution scanning electron microscopy (HRSEM), energy...

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...
