  2. 1. High-capacity short-reach optical communications

    Author : Rui Lin; Jiajia Chen; Lena Wosinska; Yu Yu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical communication; optical frequency comb; radio-over-fiber; optical interconnect; fiberoptisk kommunikation; optisk frekvenskams; Radio-över –fiber; passiva optiska interconnects; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : The global traffic is experiencing an exponential growth posing severe challenges to the communication networks in terms of capacity. As a future-proof technology fiber communication is widely implemented in different network segments, which can be categorized by transmission distance as long-haul and short-reach. READ MORE

  4. 2. Quantum Transport in Superconductor-Semiconductor Nanowire Hybrid Devices

    Author : Chunlin Yu; NanoLund: Centre for Nanoscience; []
    Keywords : Nanowire; InSb; Transport; Quantum dot; Majorana bound states; Andreev bound states; the Kondo effect; Superconductivity; Fysicumarkivet A:2018:Yu;

    Abstract : In this thesis, we study quantum transport properties of superconductor-semiconductor nanowire hybrid devices. We mainly focus on the quantum transport in InSb nanowire Josephson quantum dot devices, i.e. quantum dots coupled to two pieces of superconductors. READ MORE

  5. 3. Treatment of organic pollutants in high salinity wastewater : new catalysis systems

    Author : Han Yu; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High salinity wastewater; Electrochemical catalysis; Photo-electro catalysis; Degradation;

    Abstract : High salinity wastewater (HSW, NaCl mass fraction ≥ 1%) from industries and aquacultures contains massive organic matters with a wide variety. These organic matters have been considered as significant threaten to both human and environment. The removal and degradation of them before discharge emerge as necessity. READ MORE

  6. 4. Regulation of Human Papillomavirus Type 16 Early and Late Gene Expression

    Author : Haoran Yu; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HPV16; mRNA; Splicing; gene expression;

    Abstract : Human papillomavirus type 16 (HPV16) is a cancer-causing virus that contributes to at least 70% of cervical cancer as well as to other anogenital cancers and head and neck cancer. Understanding HPV16 gene regulation is important to enhance our understanding of HPV16 infections and may contribute to development of antiviral drugs. READ MORE

  7. 5. Synthesis of N-Containing Compounds: Development of Methodology and its Application in Total Synthesis

    Author : Lu Yu; Centrum för analys och syntes; []
