A Characteristic Analysis of Bio-ethanol produced on Fruit wastes for Direct Ethanol Fuel Cell (DEFC)

Kim H., Lee N., Cha I., Choi J., Center for Organic Agrifood industrialization, KR

This Study is aimed to produce bio-ethanol based on the fruit wastes and optimize the bio-ethanol production for a direct ethanol fuel cell(DEFC). Fruit wastes such as pear, apple, persimmon were used in the conditions [...]

Effect of Dynamic Environment on the Interaction between Nanoparticles and A549 Monolayer

Patel H., Kim H., Kwon S., Utah State University, US

The carbon nanotube (CNT) has been well explored for many proven applications, but very little explored to understand its potential toxic effects. It is crucial to develop viable alternatives to in vivo tests to evaluate [...]

Thin film solar cell based on microcrystalline nanostructure silicon grown in low temperature condition

Single-layer, multi-layer, and patterned nanostructures were fabricated with aids of substrates from various material systems (polymers, diblock copolymers, polymer blends, alumina precursors, silane precursor, etc.) using wet spin-coating and subsequent dry and thermal process, chemical [...]

Biocompatibilities of some synthetic polymers in films

Kim G., Kim H., Yoon J., Ree M., Kim G., Kim H., Pohang University of Science and Technology, KR

Materials for artificial devices require biocompatibility with the human body. Moreover, it has been well known that the implants are facilely tainted with pathogenic bacteria during surgical processes and that a few bacteria circulate in [...]

Ab Initio Calculations on Magnetic Properties of Diluted Magnetic Semiconductors

Kim H., Kim Y-S, Kim H., Kim Y-S, Chung Y-C, Hanyang University, KR

Some diluted magnetic semiconductors (DMS), in which magnetic elements are substituted for a small fraction (~5%) of host elements in a semiconductor lattice, show ferromagnetism, and thus possess potential applicability in spintronics. To obtain quantum-mechanical [...]
