  2. 21. Extreme Implementations of Wide-Bandgap Semiconductors in Power Electronics

    Author : Juan Colmenares; Hans-Peter Nee; Leon M. Tolbert; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cryogenic; Gallium Nitride; Gate Driver; Harsh Environments; High Efficiency Converter; High Temperature; MOSFETs; Normally- ON JFETs; Reliability; Silicon Carbide; Wide-Band Gap Semiconductors; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Wide-bandgap (WBG) semiconductor materials such as silicon carbide (SiC) and gallium-nitride (GaN) allow higher voltage ratings, lower on-state voltage drops, higher switching frequencies, and higher maximum temperatures. All these advantages make them an attractive choice when high-power density and high-efficiency converters are targeted. READ MORE

  4. 22. Silicon Carbide High Temperature Photodetectors and Image Sensor

    Author : Shuoben Hou; Mikael Östling; Carl-Mikael Zetterling; Per-Erik Hellström; Anthony O'Neill; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon Carbide SiC ; high temperature; photodetector; photodiode; phototransistor; ultraviolet UV ; transistor-transistor logic TTL ; bipolar junction transistor BJT ; integrated circuit IC ; pixel sensor; image sensor; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Silicon Carbide (SiC) has the advantages of ultraviolet (UV) sensing and high temperature characteristics because of its wide band gap. Both merits make SiC photodetectors very attractive in astronomy, oil drilling, combustion detection, biology and medical applications. READ MORE

  5. 23. Two novel combination therapies of glioblastoma multiforme from a Cx43 perspective : studies of in vitro models

    Author : Thomas Asklund; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Glioma; gap junction; Cx43; bystander effect; HSV-tk; HDAC inhibitor; tyrosine kinase inhibitor;

    Abstract : The group of patients suffering from the malignant brain tumour glioblastoma multiforme (GBM) have a median survival of only about one year. Thus, new treatment strategies are urgently needed. Gap junctions are intercellular channels, permitting intercellular transfer of water soluble substances. READ MORE

  6. 24. Neural stem cell-mediated enhanced gene therapy of malignant gliomas using a novel plant thymidine kinase

    Author : Zahidul Khan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Malignant glioma; suicide gene therapy; bystander effect; gap junction; neural stem cell; 4-phenylbutyrate; epigenetics; cell differentiation;

    Abstract : Malignant gliomas are the most common brain tumors in adults. Approximately, 190,000 new patients are diagnosed with malignant gliomas worldwide every year. Unfortunately, the prognosis of malignant gliomas still remains very poor, despite advances in management. READ MORE

  7. 25. The synthesis, characterization and device fabrication of ZnO, NiO and their composite nanostructures

    Author : Mazhar Ali Abbasi; Magnus Willander; Maxim Ryzhii; Linköpings universitet; []
    Keywords : Zinc oxide; Nickel Oxide; Composite nanostructures; Wide band gap; Low temperature growth; Luminescence; Photo-detector; Light emitting diode;

    Abstract : Electronics industry has been revolutionized since last few decades because of the fabrication of electronic devices by using nanoscale based materials. But the more innovative feature in the electronic devices is the use of transparent materials, which makes the transparent electronic devices as one of the most interesting research field in nanoscience and nano-technology now a days.
