Effect of Thermal Properties of Die Attach Materials on Performance of High Power Blue Leds
InGaN-based High Power blue LEDs exhibit a maximum light conversion efficiency of 40%, which decreases further at high drive currents. Thus, more than 60% of the electrical input power is dissipated as heat in an LED chip, leading to a rise in the junction temperature of the LED. Junction temperature has a significant impact on the light conversion efficiency of the LEDs. Also, it reduces LED l...
متن کاملFast Blue RR—Siloxane Derivatized Materials Indicate Wound Infection Due to a Deep Blue Color Development
There is a strong need for simple and fast methods for wound infection determination. Myeloperoxidase, an immune system-derived enzyme was found to be a suitable biomarker for wound infection. Hence, alkoxysilane-derivatized Fast Blue RR was immobilized via simple hydrolytic polymerization. The resulting enzyme-responsive siloxane layers were incubated with myeloperoxidase, wound fluid or hemog...

متن کاملDeep Blue
Deep Blue was the first chess computer to defeat a reigning human world chess champion in a regulation match. A number of factors contributed to the system's success, including its ability to extract useful knowledge from a database of 700,000 Grandmaster chess games—a process that has implications for any non-chess knowledge-discovery application involv-A vast database of human experience can ...
متن کاملBlue fluorescent OLED materials and their application for high-performance devices
The authors applied two technologies to improve the efficiency of fluorescent blue organic light-emitting diodes (OLEDs). First, an efficiency-enhancement layer (EEL) was introduced to boost triplet-triplet fusion (TTF). Second, new blue dopants with a higher orientation factor in the emitting layer were developed. Consequently, the external quantum efficiency (EQE) was increased up to 11.5% wi...
