Thermal Management Strategies for Low and High Voltage Retrofit LED Lamp Drivers
Several thermal management strategies for LED drivers designed for high lumen retrofit LED lamps are studied by simulation and experimentation means. Depending on the driver output, two scenarios are analyzed: Low Voltage-High Current (18V-620mA) and High Voltage-Low Current (110V-85mA).
Resistive Switching with Self-Rectifying Tunability and Influence of the Oxide Layer Thickness in Ni/HfO2/n+-Si RRAM Devices
The impact of the dielectric thickness, forming polarity, and current compliance on the self-rectifying current–voltage characteristics of Ni/HfO2/n+-Si RRAM devices has been investigated.
Impedimetric label-free sensor for specific bacteria endotoxin detection by surface charge registration
An impedimetric sensor based on a three dimensional electrode array modified with consecutive deposition of Con A-glycogen-Con A layers was used for label-free detection of bacterial endotoxin: lipopolysaccharide (LPS) from Escherichia coli.
