Phenomena related to global warming have been of particular interest among researchers, strongly encouraging them to identify various methods of adsorbing contributing gases, such as CH4 and CO2 [1,2]. Many adsorbents have been widely proposed and studied to remove greenhouse gases from the atmosphere and protect the environment [3,4]. Carbon-based materials for adsorption are an intriguing subject owing to their very high specific surface area, low weight, and elasticity [5,6]. Among various...

In this work, we studied the effects of electrochemical oxidation treatments of carbon fibers (CFs) on interfacial adhesion between CF and epoxy resin with various current densities. The surface morphologies and properties of the CFs before and after electrochemical-oxidation-treatment were characterized using field emission scanning electron microscopy, atomic force microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and single-fiber contact angle. The...

This review presents current progress in the preparation methods of liquid crystalline nanocarbon materials and the liquid crystalline spinning method for producing nano-carbon fibers. In particular, we focus on the fabrication of liquid crystalline carbon nanotubes by spinning from superacids, and the continuous production of macroscopic fiber from liquid crystalline graphene oxide.

Carbon-supported Pt catalyst systems containing defect adsorption sites on the anode of direct methanol fuel cells were investigated, to elucidate the mechanisms of H2 dissociation and carbon monoxide (CO) poisoning. Density functional theory calculations were carried out to determine the effect of defect sites located neighboring to or distant from the Pt catalyst on H2 and CO adsorption properties, based on electronic properties such as adsorption energy and electronic band gap. Interestingly,...

Impact damages induced by a low-velocity impact load on carbon fiber reinforced polymer (CFRP) composite plates fabricated with various stacking sequences were studied experimentally. The impact responses of the CFRP composite plates were significantly affected by the laminate stacking sequences. Three types of specimens, specifically quasi-isotropic, unidirectional, and cross-ply, were tested by a constant impact carrying the same impact energy level. An impact load of 3.44 kg, corresponding to...

The development of global citizenship among teachers needs to begin even before teachers sign their first contract. Global citizenship development should start when teacher candidates are being prepared to teach. Using the Critical Cosmopolitan Theory (Byker, 2013), this article examines the integration of a global citizenship curricula in teacher education programs in North Carolina and Texas. The article describes and compares the teacher candidates’ (n=136) perceptions of the global...

This article examines the place of global citizenship education in schools by critically analyzing the official curriculum in one US state, Georgia. Data in the study includes Georgia Department of Education documentation about the implementation of the K-8 Georgia Performance Standards for Social Studies, particularly the 6th and 7th grade “world studies standards”. An interpretive document analysis is used to identify patterns of inclusion and exclusion which are then examined to assess...

The Korean government’s move to implement criterion-referenced assessment in secondary schools has impacted the nation socially and politically as well as educationally. Since education policy is a matter not of only education itself but of a nation’s politics, culture and economy, the issue of criterion-referenced assessment in secondary schools has been hotly debated before and even during its implementation. With the government’s interest in implementing criterion-referenced assessment in...

Objectives: This study investigated life stressors as risk factors for manifestations of adolescent Internet addiction, as well as the mediating roles of self-efficacy and perceived parental support/affection. It examined the influence from each parent, which has been addressed minimally in previous studies. Methods: The 4th wave of data from the Korean Education and Employment Panel Survey was used for the analysis. Our model includes six stressor risk factors including academic stressors,...
