1. 11. Tactile sensing of prostate cancer : a resonance sensor method evaluated using human prostate tissue in vitro

   Författare :Ville Jalkanen; Olof Lindahl; Britt Andersson; Tomas Jansson; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tactile resonance sensor; prostate tissue; prostate cancer; stiffness; density; elastic; variations; tissue histology; Medical engineering; Medicinsk teknik;

   Sammanfattning : Prostate cancer is the most frequent type of cancer in men in Europe and the USA. The methods presently used to detect and diagnose prostate cancer are inexact, and new techniques are needed. LÄS MER

3. 12. On the Diluent and Solvent Effects in Liquid-Liquid Extraction Systems based on Bis-triazine-bipyridine (BTBP) ligands

   Författare :Elin Löfström Engdahl; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Solvent effects; Diluent effects; GANEX; Interfacial tension; Density;

   Sammanfattning : Used nuclear fuel is dangerous for mankind and her environment for a long time. If however, the minor actinides together with uranium and plutonium could be transmuted, i.e. transformed, into more shortlived or stable isotopes the volume of the waste could be significantly reduced together with a reduction in the radiotoxicity.

4. 13. Diluent and Solvent Effects in Liquid-Liquid Extraction Systems based on bis-triazine-bipyrididine (BTBP)-class Ligands

   Författare :Elin Löfström Engdahl; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Used nuclear fuel; Density; Solvent; Extraction vs. time; BTBP; GANEX; Liquid-Liquid Extraction; Interfacial tension; Diluent;

   Sammanfattning : Used nuclear fuel taken directly from a reactor is radiotoxic for mankind and its environment for a long time. One of the major contributions to the long time radiotoxicity is the presence of a group of elements called the actinides. LÄS MER

5. 14. Thermally stable electrical contacts to 6H silicon carbide

   Författare :Nils Lundberg; Mikael Östling; Claude Jaussaud; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; I-V current -voltage ; C-V capacitance-voltage ; rectifying; ohmic; interface; silicide; carbide; epilayer; Schottky barrier height; current rectification ratio CRR ; specific contact resistivity; transmission line model TLM ; contact resistance; transfer length; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Silicon Carbide (SiC) are at present being developed for use in high temperature (≥ 500◦C) and high-power environments under which conventional semiconductors can hardly perform.  Thermally stable electrical contacts are essential to the ability of SiC to function under such extreme conditions.

7. 15. GENOME2QUNOME : Interfacing Molecules with Nanomaterials

   Författare :Pritam Kumar Panda; Rajeev Ahuja; Yogendra Kumar Mishra; Helder Almeida Santos; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Electronic transport; Contact electrification; Nanomaterials; Zinc Oxide; Tetrapods; 2D-materials; Density functional theory; Non-equilibrium Green s function; Molecular docking; Molecular dynamics simulation; Materialvetenskap; Materials Science; Theoretical Physics; Teoretisk fysik; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

   Sammanfattning : The advent of technological furtherance in the biomedical sector and the renaissance of interdisciplinary science enable us to comprehend human lifestyle, and diseases at molecular and nanoscale levels. Lacking a shared theoretical foundation and terminological lexicon between various scientific domains might impede efforts to incorporate biological principles into nanoscience. LÄS MER
