1. 1. Investigation of Novel Metal Gate and High-κ Dielectric Materials for CMOS Technologies

   Författare :Jörgen Westlinder; Jörgen Olsson; Stefan Bengtsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; metal gate; high-κ dielectics; titanium nitride; zirconium nitride; MOSFET; thin film; tantalum oxide; aluminum nitride; Elektronik; Electronics; Elektronik;

   Sammanfattning : The demands for faster, smaller, and less expensive electronic equipments are basically the driving forces for improving the speed and increasing the packing density of microelectronic components. Down-scaling of the devices is the principal method to realize these requests. LÄS MER

3. 2. Developmental Aspects of Drug Transport Across the Blood-Brain Barrier

   Författare :Jörgen Bengtsson; Margareta Hammarlund-Udenaes; Ann-Cathrin Engwall; Sven Björkman; Elizabeth C.M. de Lange; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; development; active transport; tight junction proteins; microdialysis; recovery; morphine; nitrofurantoin; Bcrp; microarray; real-time PCR; in vitro; in vivo; LC-MS MS; Biopharmacy; Biofarmaci; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

   Sammanfattning : The developmental aspect of drug transport across the blood-brain barrier (BBB) was investigated. Microdialysis was used to study unbound morphine BBB transport at different ages in sheep. An in vitro study was performed to find differentially expressed genes in brain capillary-rich fractions of the brain in rats of different ages. LÄS MER

4. 3. Diffractive Optics Design

   Författare :Jörgen Bengtsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computer-generated waveguide hologram; diffractive optics; fan-out; millimeter wave radiation; proximity effect; optimal-rotation-angle method; kinoform; integrated optics; beam shaping; outcoupling grating; scalar optics;

   Sammanfattning : Diffractive optical elements (kinoforms) change the way light propagates, and can perform very complex tasks. They can split an incident beam into any number of outgoing, and possibly focused, beams (fan-out). LÄS MER
