investigation of the electronic properties of carbon and iii-v nanotubes

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...

Fundamental characteristics of material removal and surface formation in diamond turning of porous carbon

Porous carbon is an important material for manufacturing ultraprecision air bearings. This paper investigates the material removal mechanism and surface quality of porous carbon in diamond turning process. A total of 32 diamond turning tests were performed and the effects of feed rate, depth of cut, cutting speed, and tool rake angle were investigated. Scanning electron microscopy of the machin...

Evaluation of Toluene Adsorption Performance of Mortar Adhesives Using Porous Carbon Material as Adsorbent

Porous carbon materials are advantageous in adsorbing pollutants due to their wide range of specific surface areas, pore diameter, and pore volume. Among the porous carbon materials in the current study, expanded graphite, xGnP, xGnP C-300, xGnP C-500, and xGnP C-750 were prepared as adsorbent materials. Brunauer-Emmett-Teller (BET) analysis was conducted to select the adsorbent material throug...

English Language Teaching Material Development

The goal of language programs is to utilize language for effective communication. Due to the needs, interests, and motivations of language learners, they may show individual differences in their lan- guage learning. Materials used in language programs can be instructional, experiential, elucidative, or exploratory in that they can inform learners about the language, provide experience of the la...
