1. Design, Simulation and Characterization of Some Planar Lightwave Circuits
Sammanfattning : Optical devices based on planar lightwave circuit (PLC) technology have the advantages of small size, high reliability, possibility for large scale production, and potential integration with electronics. These devices are widely employed in optical telecommunications, sensing, data storage, imaging, and signal processing. LÄS MER
2. Top-down Fabrication Technologies for High Quality III-V Nanostructures
Sammanfattning : III-V nanostructures have attracted substantial research effort due to their interesting physical properties and their applications in new generation of ultrafast and high efficiency nanoscale electronic and photonic components. The advances in nanofabrication methods including growth/synthesis have opened up new possibilities of realizing one dimensional (1D) nanostructures as building blocks of future nanoscale devices.

3. CO2 Capture using Chemical-Looping Combustion – Operational Experience with Gaseous and Solid Fuels
Sammanfattning : CO2 capture and storage has been proposed as an alternative to mitigate global warming. Chemical-looping combustion (CLC) is an unmixed combustion concept where fuel and combustion air are kept separate by means of an oxygen carrier, and the CO2 capture is inherently achieved. LÄS MER
4. Chemical-Looping Combustion with Natural Gas Using NiO-Based Oxygen Carriers
Sammanfattning : CO2 capture and storage has been proposed as an alternative to mitigate global warming. Chemical-looping combustion is an unmixed combustion concept where fuel and combustion air are kept separate by means of an oxygen carrier and the CO2 capture is inherently achieved. LÄS MER
5. Millimeter-wave Communication and Radar Sensing — Opportunities, Challenges, and Solutions
Sammanfattning : With the development of communication and radar sensing technology, people are able to seek for a more convenient life and better experiences.
