16. Preparation and characterization of graphene/metal composites
Sammanfattning : Since the isolation of graphene in 2004, much research has been conducted to understand this novel material and how its properties can be utilized in different applications. One type of venture involves graphene as a reinforcing filler in metal matrix composites (MMC) which is becoming increasingly prevalent in the automotive and aerospace industries. LÄS MER
17. Characterization & modeling of chip flow angle & morphology in 2D & 3D turning process
Sammanfattning : Within manufacturing of metallic components, machining plays an important role and is of vital significance to ensure process reliability. From a cutting tool design perspective, tool macro geometry design based on physics based numerical modelling is highly needed that can predict chip morphology. LÄS MER
18. Processing, Characterization and Modeling of AlGaN/GaN HEMTs
Sammanfattning : III-Nitrides electronic properties make them currently the materials of choice for high-power high-frequency applications. Their wide bandgaps, high breakdown fields, the high electron peak and saturation velocities combined with the large conduction band offset and the high electron mobility observed in AlGaN/GaN heterostructures enable excellent microwave power performance of AlGaN/GaN high electron mobility transistors (HEMTs).
