New Nanostructures as novel electrodes in Capacitive deionization desalination Technology

Barakat, N.A.M., Chonbuk National University, KR

Among the various introduced technologies for water desalination, capacitive deionization (CDI) is a very promising process. CDI (also called Electrosorption) attracted enormous attention as an energy-saving and environmentally friendly desalination technique, because it can be [...]

Aqueous Dispersion of Single-Walled Carbon Nanotubes by using Self-doped Polyaniline as Dispersant

Hong, M.S., Hwang, J.H., Lee, H.J., Lee, H.S., Lee, M.H., Chonbuk National University, KR

In this research, a water-soluble self-doped polyaniline, poly(aniline N-butylsulfonate) (PAnBuS), was introduced to disperse SWNTs. Dispersion of SWNTs functionalized with PAnBuS was achieved ex-situ by simply mixing both components using ultrasonic treatment. The PAnBuS-functionalized SWNTs [...]

Determination of micro-structural properties with x-ray absorption fine structure

Han, S.-W., Jeong, E.-S., Kim, S-H, Kim, Y.J., Park, S.H., Yi, G.-C., Yu, H.-J., Chonbuk National University, KR

We studied the structural properties of ZnO nanostructures with x-ray absorption fine structure (XAFS) to understand the growth mechanism of vertically aligned ZnO nanorods of the average diameter of 50 - 150 nm. The orientation-dependent [...]

Fabrication of ZnO hybrid structures and light emitting diode applications

Han, S.-W., Kim, S-H, Kwak, C.-H., Lee, Y.B., Park, S.H., Seo, S.-Y., Chonbuk National University, KR

Vertically well aligned ZnO nanorod arrays with a diameter of 50 - 150 nm were fabricated on Al2O3 substrates with and without GaN interlayers, and consequently covered with a crystalline ZnO film in-situ by a [...]

Fabrication of electrochemical bio-sensors for the detection of glucose and hydrazine using ZnO nanonails grown by the thermal evaporation process

Hahn, Y.B., Kim, J.H., Kim, S-H, Park, Y.K., Umar, A., Chonbuk National University, KR

Well-crystallized zinc oxide nanonails have been synthesized in a large quantity via a thermal evaporation method using the metallic zinc powder without the use of any metal catalyst or additives. The detailed structural and optical [...]

Preparation of Functional LLDPE/LDPE/TiO2 Membranes

Hong, C-E, Lee, J-H., Wang, X-Y, Wang, X., Chonbuk National University, KR

Nano-scaled TiO2 has now been used in polymer industry due to its promising properties in light catalyst and UV light shielding[1-3]. In the present paper, functional LLDPE/LDPE/TiO2 membranes were successfully manufactured. To solve the poor [...]
