  • Conceptions of the nature of science and worldviews of preservice elementary science teachers in Taiwan

    Creator:
    Liu, Shiang-Yao
    Abstract:
    This exploratory investigation aimed to identify preservice science teachers' conceptions of the nature of science (NOS), and worldviews that represent their culturally dependent beliefs about the world, in the context of Taiwan. The interrelationships between the responses elicited from both the assessments of NOS understandings and worldviews were examined. Participants...

  • IC-Antenna Co-Integration for Efficient and Scalable Millimeter-Wave Antenna Interfaces

    Creator:
    Liu,Yao
    Abstract:
    Millimeter-wave (mm-wave) technology promises high speed, high system capacity and low latency interconnects with reduced cost. Applications like high data-rate wireless links, next generation automotive sensors and security body scanners highly depend on mm-wave technology innovations. As operating frequency moves to higher mm-wave bands, shrinking antenna dimensions enable co-integration of...

  • Fluidized-bed nitridation of silicon : direct use of very fine powder for [α]-silicon nitride production

    Creator:
    Liu, Yao-Dian
    Abstract:
    2 μm average sized silicon powder was nitrided with 90% N₂/10% H₂ in a fluidized-bed reactor, operated at 1200°C, 1250°C and 1300°C. To fluidize silicon powder, alumina particles with an average size of 300 μm were used as an inert fluidizing conditioner. The feasibility and operating conditions of the fluidization...
