Hydroxyethyl Cellulose Filled with M2+ Chelate Complexes with EDTA as an Effective Electron-Injection Layer for PLEDs
Yun Chen

An effective electron-injection layer (EIL) is crucial to the development of highly efficient polymer light-emitting diodes (PLEDs) using stable, high work-function metals as the cathode. In this study, we demonstrate the use of a water-soluble natural-derived polymer, hydroxyethyl cellulose (HEC), mixed with organic salts (ethylenediaminetetraacetic acid tetrasodium or sodium acetate, …

Acute hypernatremia dampens stress-induced enhancement of long-term potentiation in the dentate gyrus of rat hippocampus
Kuei-Sen Hsu

Stress is a common experience in daily life. It initiates adaptive processes that allow the organism to physiologically cope with environmental perturbations in maintaining homeostasis and promoting survival. Stress often occurs within the context of homeostatic threat, requiring integration of physiological and psychological demands to trigger appropriate behavioral, autonomic and endocrine …

Cascaded GaN light-emitting diodes with hybrid tunnel junction layers
Shoou-Jinn Chang

GaN-based LEDs are also used for commercial solid-state lighting nowadays. However, GaN-based LEDs are still not cost effective. To further enhance the penetration rate of solid-state lighting, we thus need to reduce the production cost of these devices. One possible way to reduce the production cost is to serially grow two InGaN-GaN multiquantum well (MQW) structures on the same sapphire …

Determination of 87Sr/86Sr and δ88/86Sr ratios in plant materials using MC-ICP-MS
Chen-Feng You

Growth of higher plants extracts the bio-essential metals from the soils, chemical reactions in the rhizosphere facilitate the metal uptake through roots, and the metabolic processes continuously control the behavior of metals and their translocation between the reservoirs in plants. There are a number of reasons for studying uptake of metals and the associated effects on plant growth and …
