2. 1. Thermal Stability of Electrodeposited Nanocrystalline Ni- and Co-Based Materials

   Author : Melina da Silva; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanocrystalline materials; 3DAP; nanocomposite; thermal stability; TEM; nickel; texture; DSC; cobalt; grain growth; EBSD;

   Abstract : The attractive properties associated with nanocrystalline materials are to a large extent a result of their high intercrystalline volume fraction. However, the intrinsic instability of the nanostructured state may compromise the gain in properties by the occurrence of grain growth during exposure at elevated temperatures. READ MORE

4. 2. Copper and Silver Metallization for High Temperature Applications

   Author : Shabnam Mardani; Shili Zhang; Hans Norström; Jörgen Olsson; Christophe Detavernier Detavernier; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallization; Copper; Silver; Tantalum; High tempreture; Diffussion; Electromigration; Stability;

   Abstract : High-temperature electrical- and morphological-stability of interconnect is critical for electronic systems based on wide band gap (WBG) semiconductors. In this context, the thermal stability of both Ag and Cu films with Ta and TaN films as diffusion barriers and/or surface-capping layers at high temperatures up to 800 oC is investigated in this thesis.

5. 3. Interaction of Ni with SiGe for electrical contacts in CMOS technology

   Author : Johan Seger; Shi-Li Zhang; Christian Lavoie; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; MOSFET; NiSi; SiGe; phase formation; morphological stability; Fysik; Physics; Fysik;

   Abstract : This thesis investigates the reactive formation of Ni mono-gernanosilicide, NiSi1-uGeu, for contact metallization of future CMOS devices where Si1-xGex can be present in the gate, source and drain of a MOSFET. Although the investigation has been pursued with a strong focus on materials aspects, issues related to process integration in MOSFETs both on conventional bulk Si and ultra-thin body SOI have been taken into consideration.

6. 4. Cell-penetrating peptides : Uptake, stability and biological activity

   Author : Tina Holm; Ülo Langel; Roland Brock; Stockholms universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; Neurochemistry and Neurotoxicology; neurokemi och neurotoxikologi;

   Abstract : Cell-penetrating peptides (CPPs) have emerged as a group of remarkable delivery vectors for various hydrophilic macromolecules, otherwise excluded from cells due to the protective plasma membrane. Unbiased conclusions regarding e.g. READ MORE

7. 5. Atherosclerotic Plaque Stability and Vascular Repair

   Author : Anki Knutsson; Kärlväggsbiologi; []
   Keywords : atherosclerosis; diabetes; repair; inflammation; extracellular matrix;

   Abstract : Myocardial infarction and stroke are two of the most common causes of death in the world, mainly caused by a rupture of an atherosclerotic plaque. A vulnerable atherosclerotic plaque is a high-risk plaque that can form a thrombus by rupture. READ MORE
