Performance and emission characteristics of a diesel engine fueled with functionalized multi-wall carbon nanotubes (MWCNTs-OH) and diesel-biodiesel-bioethanol blends
Shekofteh, Mohammad; Gundoshmian, Tarahom Mesri; … - In: Energy Reports 6 (2020), pp. 1438-1447
Biodiesel is one of the renewable fuels which is similar to diesel fuel. Biodiesel fuel has more oxygen than diesel fuel and this leads to better combustion and thereby, decreases PM, CO, and UHC emissions. On the other hand, biodiesel has a higher viscosity and density than diesel fuel which...

A CNT (carbon nanotube) paper as cathode gas diffusion electrode for water management of passive μ-DMFC (micro-direct methanol fuel cell) with highly concentrated methanol
Deng, Huichao; Zhang, Yufeng; Zheng, Xue; Li, Yang; … - In: Energy 82 (2015) C, pp. 236-241
A novel MEA (membrane electrode assembly) structure of passive μ-DMFC (micro-direct methanol fuel cell) controls water management and decreases methanol crossover. The CNT (carbon nanotube) paper replacing CP (carbon paper) as GDL (gas diffusion paper) enhances water back diffusion which...

CONTACT EFFECTS ON TRANSPORT PROPERTIES OF SEMICONDUCTING CARBON NANOTUBES CONNECTED TO METALLIC ELECTRODES
KOBAYASHI, NOBUHIKO; OZAKI, TAISUKE; HIROSE, KENJI - In: Surface Review and Letters (SRL) 13 (2006) 02, pp. 309-311
We present the first-principles calculation of transport properties of a semiconducting carbon nanotube connected to aluminum metallic electrodes. The transmission spectrum of the nanotube shows a decrease in the band-gap energy level but has a finite value due to the hybridization of the...

Phase behavior and fluid–solid surface tension of argon in slit pores and carbon nanotubes
Hamada, Yoshinobu; Koga, Kenichiro; Tanaka, Hideki - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 12, pp. 2289-2298
Phase behaviors of argon in several types of cylindrical and slit pores are examined by grand-canonical Monte Carlo simulations. Condensation processes in single- and multi-walled carbon nanotubes along with those in hard-wall tubes are compared. Effects of the pore size on pressure–tensor...

Translocation of DNA oligonucleotide through carbon nanotube channels under induced pressure difference
Lim, Melvin C.G.; Pei, Q.X.; Zhong, Z.W. - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 13, pp. 3111-3120
This paper presents molecular dynamics (MD) simulations of DNA oligonucleotide and water molecules translocating through carbon nanotube (CNT) channels. Induced pressure difference is applied to the system by pushing a layer of water molecules towards the flow direction to drive the...
