This paper introduces a nitrogen-doped ordered mesoporous carbon (NOMC) derived from glucosamine with hybrid capacitive behaviors, achieved by successfully combining electrical double-layer capacitance with pseudo-capacitance behaviors. The nitrogen doping content of the fabricated NOMC reached 7.4 at% while its specific surface area (SBET) and total pore volume reached 778 m2 g?1 and 1.17 cm3 g?1, respectively. A dual mesoporous structure with small mesopores centered at 3.6 nm and large...

a substrate used for several chemical transformations, including its reduction to related materials, such as rGO and graphene. The rGO has been used recently to increase catalytic activity in the o-nitroaniline reduction to NaBH4 and Raman activity in test molecules as p-aminothiophenol [1]. Other authors showed that the rGO in combination with carbon nanotubes has the properties of supercapacitors [2]. Mao et al. [3] obtained a gas sensor type field defect transistor of high sensitivity at low...

Polyacrylonitrile (PAN)-based carbon fibers have high specific strength, elastic modulus, thermal resistance, and thermal conductivity. Due to these properties, they have been increasingly widely used in various spheres including leisure, aviation, aerospace, military, and energy applications. However, if exposed to air at high temperatures, they are oxidized, thus weakening the properties of carbon fibers and carbon composite materials. As such, it is important to understand the oxidation...

People have been concerned about mercury emissions for decades because of the extreme toxicity, persistence, and bioaccumulation of methyl Hg transformed from emitted Hg. This paper presents an overview of research related to mercury control technology and identifies areas requiring additional research and development. It critically reviews measured mercury emissions progress in the development of promising control technologies. This review provides useful information to scientists and engineers...

The element carbon has been used as a source of energy for the past few hundred years, and now in this era of technology, carbon has played a significant and very prominent role in almost all fields of science and technology. So as an honour to this marvellous element, we humans should know about its various forms of existence. In this review article, we shed light on all possible carbon-allotropes; similarities in their synthesis techniques and the starting materials; their wide range of...

My introduction to carbon science was unplanned and unexpected. After I received my B.A. in physics from the University of Cambridge (UK) in 1960, I agreed to take an appointment at the United Kingdom Atomic Energy Authority (UKAEA) Atomic Energy Research Establishment (AERE), Harwell, UK. Starting September 1, I was to work on a project studying focused collision sequences in metals. For personal reasons, I was not able to report until a month later, when I was informed that my original...

using X-ray diffraction and transmission electron microscopy. The results showed successful deposition of Pt nano-particles, with crystallite size of about 2.7 nm, on the PPy-RGO support film. Catalytic activity for methanol electrooxidation in fuel cells was investigated using cyclic voltammetry. The fundamental electrochemical test results indicated that the electro-catalytic activity, for methanol oxidation, of the Pt/PPy-RGO combination was much better than for commercial catalyst.

이 연구는 리듬청각자극으로 제공된 사물놀이의 자진모리장단이 노인의 즉각적 상지근육 활동에 미치는 영향을 알아보고자 한 것이었다. 즉각적 상지근육 활동은 상지근육의 전기적 에너지 주파수와 전반적 활동도로 측정되었다. 연구의 대상은 Y시 소재의 노인시설에 거주하고 있는 60-89세의 남녀노인 10명으로 구성되었다. 연구절차는 피험자가 북을 치는 동안 1) 외부적인 청각자극이 없을 때 2) 피험자의 내재박(Limit Cycle)과 일치하는 빠르기의 기본리듬을 청각자극으로 제공할 때 3) 피험자의 내재박(Limit Cycle)과 일치하는...
