Interest in wearable electronics for continuous, long-term health and performance monitoring is rapidly increasing. The reduction in power levels consumed by sensors and electronic circuits accompanie...
Northwestern Engineering researchers have designed a quantum cascade laser (QCL) frequency comb that is dramatically more efficient than previous iterations. Led by Manijeh Razeghi, researchers i...
Current trends in energy consumption and biofuel manufacturing are neither secure nor sustainable, because they are not provided by necessary cost effective technologies. Further reductions of cost an...
During last two decades great attention was paid to materials with grains of diameter smaller than 1 μm. These materials were classified as Ultra Fine Grain (UFG) materials with diameter of grains of...
Total consumption of all types of energies is rather high nowadays with constant tendency of increasing. Transport section is one of the highest consumers of energy obtained from fossil fuels. It is a...
The parabolic taper structure was introduced which is smoother than the linear taper. The structure of the parabolic taper waveguides was optimized using the transition region theorty. By introducing ...
