    Sammanfattning : 3D IC packaging technology extends Moore’s law and shifts the IC field into a new generation of smaller, but more powerful devices. Interconnection and thermal management as two critical parts of 3D IC integration packaging, are facing harsh challenges due to the miniaturization of IC devices. LÄS MER

    Sammanfattning : Fuel cells are devices which convert chemical energy into electrical energy cleanly and efficiently. Development of fuel cells compatible with hydrocarbon fuels would make more efficient use of present fossil and renewable fuels, and also enable progress towards a future hydrogen economy. LÄS MER

  7. 5. Thermoelectric Ba8Ga16Ge30 clathrates for waste heat recovery

    Sammanfattning : The modern, highly industrialized, society of today requires huge amounts of energy to function. This has resulted in a heavy dependence on the very energy efficient fossil fuels, a source of energy which of course is not infinite and we are slowly approaching the day when oil runs out. LÄS MER
