Multifunctional Micropatterned Nanofiber Capable of Cell Patterning, Metabolite Detection, and Growth Factor Delivery

Koh W.G., Lee H.J., Lee H.W., Lee H.J., Lee H.W., Park S., Yonsei University, KR

This study describes the development of multifunctional nanofiber scaffolds consisting of multiple layers of nanofiber scaffolds and nanofiber-incorporated PEG hydrogels. We fabricated double-layered nanofiber scaffolds that were micropatterned with PEG hydrogels by combining two-step sequential [...]

Design and Analysis of The CMOS Spatial Light Modulators with Flat Beam Profiles

Hsu C-P, Shih C-T, Wen S-Y, Chien Y-H, Hu C-C, Lee H.W., Industrial Technology Research Institute, TW

Two new types of electrostatic grating light modulators (GLMs) are proposed, designed, and analyzed here for improvement on optical wavefront distortion. The proposed GLMs consist different microbeam structures with spring-like legs to improve the flatness [...]

A Study on the Fabrication of Micro Structure using Chemical Mechanical Micro Machining Process

Park J.M., Lee H.W., Jeong H.D., Pusan National University, KR

Single crystal silicon is widely used in the microelectronic industry. Recent advances in ultra precision machining have enabled the possibility of direct diamond turning of high quality surfaces on the brittle materials. As a brittle [...]
