Blue light has outstanding transmission characteristics in the sea, and is known to cause the most sensitive visual response in common squid Todarodes pacificus. Application of a light emitting diode (LED) that can efficiently emit monochromatic light is expected to bring enormous energy...

A technical simulation and economic model was developed for a floating photovoltaic (PV)-battery system powering a submerged light emitting diode (LED) lighting system. The system was designed to provide around the equivalent of 1000 lumens (lm) of light of the existing light fishing technology...

LED (Light Emitting Diode) has been expected as the next generation of lighting system due to its high efficiency. However, the hot spot problem of the LED is very critical for its lifetime and efficiency. TIMs (Thermal Interface Materials) have been used to enhance the cooling performance of...

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...

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 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...

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...

Microbial fuel cells (MFCs) hold great promise as an alternative for direct biochemical energy extraction from both biomass and wastewater. However, the commercialization and scaling-up of MFCs is not completely feasible, due to the high price of platinum (Pt) as a cathode catalyst. In this...

Marine current turbine is one of the promising marine renewable energy technologies that could provide clean and sustainable energy. This field has undergone rapid growth in both industry and academia during the last decade. However, there was no study being done in incorporating nanotechnology...

Conductive and catalytic multiwalled carbon nanotube (MWCNT)/poly(3,4-ethylenedioxythiophene) polymerized with poly(4-styrenesulfonate) (PEDOT:PSS) composite films were prepared by dispersing MWCNT in the PEDOT:PSS aqueous solution using ultrasonication without any oxidation process. The effect...
