  2. 11. Perinatal regenerative medicine : development of autologous constructs for soft tissue defects

    Author : Åsa Ekblad; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Disrupted organogenesis leads to permanent malformations that may require surgical correction. Affected new-borns without spare tissue for the primary closure are dependent of other solutions. Because of the perinatal tissue shortage, synthetic or biological prosthetic materials are being used, which may be associated with complications. READ MORE

  4. 12. Epitaxial Growth and Characterization of SiC for High Power Devices

    Author : Jawad ul Hassan; Peder Bergman; Hidekazu Tsuchida; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Silicon Carbide (SiC) is a semiconductor with a set of superior properties, including wide bandgap, high thermal conductivity, high critical electric field and high electron mobility. This makes it an excellent material for unipolar and bipolar electronic device applications that can operate under high temperature and high power conditions. READ MORE

  5. 13. Copper germanide schottky contacts to silicon and electrically active defects in n-type 6H-SiC and 4H-SiC epitaxial layers

    Author : James P. Doyle; KTH; []
    Keywords : ;

    Abstract : Metallization for contacts to silicon devices presents amajor challenge as the linewidths are further reduced into thesub-micron regime. Copper germanide due to its relatively lowroom temperature resistivity ( ~ 10 µΩ - cm) has beenexamined as a potential contact metallixation. READ MORE

  6. 14. Source and drain engineering in SiGe-based pMOS transistors

    Author : Christian Isheden; Mikael Östling; Simon Deleonibus; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; SiGe; source drain; shallow junctions; pMOS; process integration; CVD; epitaxy; etching; Ni silicide; contact resistivity; Elektronik; Electronics; Elektronik;

    Abstract : A new shallow junction formation process, based on selective silicon etching followed by selective growth of in situ B-doped SiGe, is presented. The approach is advantageous compared to conventional ion implantation followed by thermal activation, because perfectly abrupt, low resistivity junctions of arbitrary depth can be obtained.

  7. 15. Dissecting gene expression regulation in mouse embryonic stems

    Author : Sandhya Malla; Francesca Aguilo; Filipe Pereira; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; molekylärbiologi; Molecular Biology;

    Abstract : Every cell within an organism is derived from a single fertilized egg that undergoes cellular differentiation and development to generate mature specialized cells. Mouse embryonic stem cells (ESCs) derived from the inner cell mass (ICM) of the pre-implantation blastocyst have proven to be a model to study gene expression during differentiation and development.
