21. Time-resolved plasmonics in designed nanostructures
Sammanfattning : A metal nanoparticle can be considered as consisting of a base of positive ion cores and a sea of free electrons. When the free electrons are displaced, for example, by an incident electric field, a restoring force acts on the electrons. The electrons may then oscillate back and forth until equilibrium is reached. LÄS MER
22. Silicon Carbide BipolarTechnology for High Temperature Integrated Circuits
Sammanfattning : The availability of integrated circuits (ICs) capable of 500 or 600° C operation can be extremely beneficial for many important applications, such as transportation and energy sector industry. It can in fact enable the realization of improved sensing and control of turbine engine combustion leading to better fuel efficiency and reduced pollution. LÄS MER
23. Engine Knock: Characteristics and Mechanisms
Sammanfattning : Knock in SI engines limits both power density and fuel conversion efficiency. The main mechanisms with the potential to generate the cylinder pressure fluctuations generally observed during knocking combustion are discussed. It is reasoned that some mechanisms of flame acceleration can further amplify a shock wave generated by autoignition. LÄS MER
