High-sensitive, direct and label-free detection technique of nanotoxic material using QCM

Jang K., You J., Park C., Park J., Park C., Park J., Na S., Korea university, KR
For the several decades, various nanomaterials are broadly used in industrial fields, research areas and commercialized products. Among many nanomaterials, silver ion, carbon nanotube, ZnO, and mercury ion etc are of the widely used nanomaterial [...]

Surfactant-Activated Microgels

Chari K., Hsu R., Bhargava P., Figura B., Yang W., Park J., Clifford T., Kadir M., Benedikt G., Lubrizol Advanced Materials, US
We describe a new class of nonionic (non-polyelectrolyte) microgels comprising crosslinked amphiphilic copolymers of alkyl acrylates and hydroxyalkyl esters that are activated by surfactant instead of pH. We discuss the mechanism of action of these [...]

Print Transferrable Large-Area Broadband Membrane Reflectors by Laser Interference Lithography

Seo J.-H., Park J., Zhao D., Yang H., Zhou W., Ju B.K., Ma Z., University of Wisconsin-Madison, US
Large-area broadband reflectors based on photonic crystals can enable a number of optoelectronic and photonics devices. To create nano patterns, nanoimprinting, electron-beam lithography and focused ion beam patterning techniques are commonly used. However, these methods [...]

Highly sensitive organic-inorganic heterojunction flexible photodetectors

Seo J.-H., Oh T.Y., Park J., Zhou W., Ju B.K., Ma Z., University of Wisconsin-Madison, US
Heterostructures formed between inorganic and organic materials could lead to many unique device applications due to their unique physical properties, such as mechanical flexibility, large area, low temperature processability and high performance. Since most n-type [...]

Development of Quantitative Adhesive Force Measurement Systems for Flexible Electronics

Kim M., Park J., Choi B., Sogang University, KR
In this paper, a novel adhesive force measurement system is developed to measure adhesive forces from interacting surfaces. In previous paper, the adhesive force was measured with tens/hundreds of uN, and the displacement was measured [...]

Reinforcement of Abrasion Resistance & Heat Buildup for Tire Tread filled with Multi-Wall Carbon Nanotubes (MWCNTs)

Oh W.S., Choi W.J., Choi Y.H., Choi W.J., Choi Y.H., Park J., Lee Y-S, NANOHUB Co., Ltd, KR
A tire tread composites containing SBR/NR rubber blend and varying proportions of multi-wall carbon nanotubes (MWCNTs)/carbon black (CB) including a silane-coupling agent [Bis-(3-triethoxysilylpropyl)tetrasulfane] have been investigated in order to reinforce abrasion resistance

Sensor application of ZnO nanowires on microheater

Park J., Kim G.-T., Maeng S., Udrea F., Milne W., ETRI, KR
We fabricated the ZnO nanowire network device using sol-gel synthesis method on the pre-patterned electrode and tested the electrical property for chemical sensing. The electrodes were prepared in various ways, for example, photolithographically defined interdigitated [...]

Active Sealing for Soft Poymer Microchips

Bang H., Lee J., Lee W.G., Park J., Yun H., Lee J., Lee W.G., Chung C., Chung S., Cho K., Chung C., Chung S., Han D-C, Chang J.K., Seoul National University, KR
This paper presents a universal sealing method for soft polymer (elastomer) microchips. A robust and reversible sealing method which allows various materials to be bonded and sealed tightly with each other even in aqueous solutions, [...]

System Identification for Motion of Proteins Using an AFM-based Nanorobotic Manipulation

Park J., Kim B-K., Kim D-H., Kim B-K., Kim D-H., Lee K-I., Korea Institute of Science and Technology, KR
It is greatly important to understand the mechanics of AFM-based nanorobotic manipulation for efficient and reliable handling of nanoparticles. Robust motion control of an AFM-based nanorobotic manipulation is much challenging due to uncertain mechanics in [...]
