Resuable Moth-Eye nano-patterned PDMS sticker with a versatile function of coating for photovoltaics.

Jung A., Cho S., Kim H., Lee H.Y., Ghymn Y.H., SOOMBI Co., Ltd., KR
In solar photovoltaic systems, enhancing absorption of the incident light on the device surface through reducing reflection is crucial for improving the system performance. In the traditional layered method for anti-reflective coatings (ARCs), however, there [...]

Rapid compressive strength achievement of coal bottom ash based geopolymer by employing microwave energy

Kim H., Hong S., University of Seoul, KR
Geopolymer has been introduced as a green alternative to Portland cement to reduce CO2 from cement industry. Unlike coal fly ash, coal bottom ash has not been used widely as a source material for geopolymer [...]

Effect of elevated hot temperatures on hybrid geopolymer synthesized with coal fly and bottom ashes

Kim H., Park C.W., University of Seoul, KR
Ordinary Portland Cement (OPC) concrete has been most widely used for construction materials although the strength deterioration of OPC concrete in high temperature has been pointed out as its inherent flaw. Considering that fire is [...]

Azide-alkyne cycloaddition by recyclable heterogeneous Cu catalysts on reverse phase silica gel

Jang Y., Kim H., Lim M., Rhee H., Hanyang University, KR
Previously, we developed heterogeneous Pd catalysts immobilized onto functionalized reverse phase silica gel. These catalysts were applied to Suzuki cross coupling reactions and the hydrogenation reactions in water with good results. In this study, Cu [...]

Pd nanoparticles immobilized onto polymer-inorganic hybrid support: Synthesis, characterization and catalytic activity on Suzuki-Miyaura coupling reactions in water

Lim M., Kim H., Jang Y., Rhee H., Hanyang University, KR
The development of heterogeneous metal catalysts supported on a solid support has attracted attention. This catalyst system has the advantages of ease of catalyst separation and reusability, and has higher reactivity due to the larger [...]

Application of a Next Generation Hand Held Antimicrobial Cold Plasma Technology

Kim H., Izadjoo M., Izadjoo S., Marcel V., Truong H., Izadjoo M., Izadjoo S., Trideum Biociences and ChiScan LLC, US
Due to emergence of antibiotic and multi-drug resistant infectious agents, there is a growing need for development of novel and effective antimicrobial therapeutics and devices. Innovative anti-infective treatment modalities, particularly for multi-drug resistant infections and [...]

Application of a Novel Cold Atmospheric Plasma for Water Decontamination

Kim H., Izadjoo M., Izadjoo S., Truong H., Izadjoo M., Izadjoo S., Trideum Biosciences and ChiScan LLC, US
In recent years, non-thermal atmospheric plasma has been considered as potential decontamination technology. The plasma can interact with ambient atmosphere and generate a variety of reactive species such as ozone, hydrogen peroxide, radical, atomic and [...]

A Novel Device for In-Vitro Electromagnetic Modulation

Eckert B., Truong H., Kim H., Izadjoo M., Trideum Biosciences and ChiScan, US
Our in-vitro experiments with cold plasma discharge have demonstrated frequency dependent modulation effects. If a large number of cold plasma discharges with different modulation frequencies can be generated at the same time, the time required [...]

Thermoelectric temperature sensors by printing with a simple office inkjet printer

Chae H., Jung M., Soum V., Lee J., Kim H., Kim T., Cheong H., Kim H., Kim T., Jeon S., Kwon O-S, Shin K., Sogang University, KR
Recently, printing temperature sensors have been significantly demanded in the paper electronics, such as electronic skin for robots, polymer chain reaction for DNA amplification. Here we present printing thermoelectric temperature sensors by using a simple [...]

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 [...]
