1. 11. Fabrication of Group IV Semiconductors on Insulator for Monolithic 3D Integration

   Författare :Ali Asadollahi; Mikael Östling; Paul R. Berger; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; monolithic three dimensional M3D integration; strained germanium on insulator sGeOI pMOSFETs; silicon silicon-germanium on insulator sSOI sSiGeOI nMOSFETs; Si0.5Ge0.5 strain-relaxed buffer SRB ; direct bonding; chemical mechanical polishing CMP ; compressively strained GeOI; tensile strained Si0.5Ge0.5OI;

   Sammanfattning : The conventional 2D geometrical scaling of transistors is now facing many challenges in order to continue the performance enhancement while decreasing power consumption. The decrease in the device power consumption is related to the scaling of the power supply voltage (Vdd) and interconnects wiring length. LÄS MER

3. 12. Decontamination of implant surfaces

   Författare :Yuki Ichioka; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental implant; peri-implantitis; surface decontamination;

   Sammanfattning : Peri-implantitis is a pathological condition occurring in tissues around dental implants. It is caused by microorganisms and characterized by inflammation in the peri-implant connective tissue and progressive loss of supporting bone. The goal of treatment of peri-implantitis is to resolve inflammation and to arrest further loss of supporting bone. LÄS MER

4. 13. On translucent yttria stabilized zirconia ceramics: Mechanical considerations, phase transformation and cement choices

   Författare :Sebastian Franco Tabares; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; zirconia; translucent; yttria; air-borne particle abrasion; 10-MDP; cement;

   Sammanfattning : New zirconia formulations (4Y and 5Y-zirconias) have been introduced for prosthodontic therapy and are commercialized as “translucent” zirconias. No clinical information providing their survival rates or complications has been provided to the date. LÄS MER

5. 14. Characterization of a Voltammetric Electronic Tongue

   Författare :John Olsson; Fredrik Winquis; Tautgirdas Ruzgas; Linköpings universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : Electronic tongues were developed some ten years ago. These systems consist of an array of nonspecific sensors and a signal processing unit. The sensor signals are processed by pattern recognition methods which makes possible the extraction of specific properties from the sample. LÄS MER

7. 15. On dental ceramics and their fracture : a laboratory and numerical study

   Författare :Wen Kou; Göran Sjögren; Tore Dérand; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental ceramics; Finite element analysis; Fixed partial denture; Fracture; Numerical modeling; Surface treatment; Biomaterials; Biomaterial; odontologi; Odontology;

   Sammanfattning : Background Surface treatments and irregularities in the surfaces may affect the fracture of ceramics. The effects of various treatments on the surface texture of different types of ceramic cores/substructures was therefore qualitatively, quantitatively and numerically evaluated. LÄS MER
