Recently, with continuous developments in the field of materials science, graphene oxide (GO) has emerged as a promising material with excellent electrical, thermal, mechanical, and optical properties, which play important roles in most fields. Researchers have achieved considerable progress with graphene. Chitosan (CS) is a natural polymer that has been studied intensively owing to its specific formation, high chemical resistance, and excellent physical properties. These outstanding properties...

In this work, thermal treatment accompanied with different acid treatments was applied to a commercial coal tar pitch (CTP) to obtain a spinnable precursor pitch for carbon fiber. In the case of thermal treatment only, a relatively high reaction temperature of between 380°C and 400°C was required to obtain a softening point (SP) range of 220°C-260°C and many meso-phase particles were created during the application of high reaction temperature. When nitric acid or sulfuric acid treatment was...

Three dimensional self-assembled graphene hydrogels were easily fabricated by electron beam irradiation (EBI) using an aqueous solution of wool/poly(vinyl alcohol) and graphene oxide (GO). After exposure to various levels of EBI radiation, the highly porous, self-assembled, wool-based graphene hydrogels were characterized using scanning electron microscopy and Fourier-transform infrared spectroscopy; to determine the gel fraction, degree of swelling, gel strength, kinetics-of-swelling analyses...

Hughes 등은 철 도가니 안에서 수소와 메탄의 혼합물로부터 모발형상의 기상성장 탄소섬유가 생성한 것을 발견하였고, 섬유는 화학기상증착법에 의해 형성된 직경이 약 20m의 탄소 필라멘트형태임을 보고하였다. 이후에 Davis 등이 전자 현미경을 사용하여 나노 크기의 직경을 가진 탄소 필라멘드를 처음으로 관찰하였고, 현재까지 많은 연구자들이 Ni,Fe,Co 및 이러한 금속들의 합금을 촉매로 이용하여 탄소나노섬유를 성장 시키는 기술을 확립하였다.

Empirical research is warranted to determine effective ways to utilize paired associate music to facilitate recall and learning. The purpose of this study was to isolate and determine the effects of mode and rhythm on working memory as measured by sequential digit recall performance. Participants were music majors (n = 30) and nonmusic majors (n = 30) at a large comprehensive university. Participants listened to six different treatment stimuli of monosyllabic digits paired with: (a) a major...
