GaN-Based Power Flip-Chip LEDs With SILAR and Hydrothermal ZnO Nanorods
Shoou-Jinn Chang

For practical solid-state lighting, one needs to deliver large power into large-size devices. The inputted electrical power will be partially converted into output light while the remaining power will be converted into heat. Without a good thermal property, the generated heat can easily fail the devices. Thus, it is extremely important to enhance thermal properties of high power LEDs. However, …

Evidence for stable Sr isotope fractionation by silicate weathering in a small sedimentary watershed in southwestern Taiwan
Chen-Feng You

Radiogenic Sr isotopes (87Sr/86Sr) are robust for provenance identification in hydrology, affected mainly by the age of background lithologies and the degree of chemical weathering. However, there is limited knowledge concerning the fractionation mechanism of stable Sr isotopes (88Sr/86Sr) in rivers. In this study, river water was collected on a weekly …

Thrombomodulin promotes diabetic wound healing by regulating toll-like receptor 4 expression
Hua-Lin Wu

An explosive global increase in the number of people diagnosed with diabetes mellitus has occurred during the past 20 years, and more than 340 million people were diagnosed with the disease in 2011. Chronic limb ulcer, a major complication of diabetes, occurs in 15% of the diabetic patients and precedes 84% of diabetes-related amputations. One of the well-known causes of this complication is …

Analysis of optically anisotropic materials by using optical coherence tomography
Yu-Lung Lo

Optical coherence tomography (OCT) is a powerful technique for performing in-depth cross-sectional imaging in scattering-type media [1]. Recent enhancements to the traditional OCT structure have enabled the incorporation of polarized control into the system to evaluate the polarization effect or anisotropic properties of certain optical materials. Several researches have been proposed and …
