4. 2. Engineering Surfaces of Solid-State Nanopores for Biomolecule Sensing

   Author : Shiyu Li; Shi-Li Zhang; Michael Mayer; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solid-state nanopores; surface engineering; DNA sensing; DNA polymerase; optical detection; lipid bilayer; hafnium oxide; electron beam induced deposition;

   Abstract : Nanopores have emerged as a special class of single-molecule analytical tool that offers immense potential for sensing and characterizing biomolecules such as nucleic acids and proteins. As an alternative to biological nanopores, solid-state nanopores present remarkable versatility due to their wide-range tunability in pore geometry and dimension as well as their excellent mechanical robustness and stability.

5. 3. Directed Energy Deposition Additive Manufacturing and Welding of Duplex Stainless Steel using Laser Beam

   Author : Amir Baghdadchi; Leif Karlsson; Joel Andersson; Vahid Hosseini; Dirk Engelberg; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Duplex stainless steel; Laser welding; Additive manufacturing; Direct Energy Deposition using a Laser Beam; Microstructure characterization; Duplexa rostfria stål; Lasersvetsning; Additiv tillverkning; Metalldeponering med laser; Mikrostruktur; Production Technology; Produktionsteknik;

   Abstract : Duplex stainless steels (DSSs), with a ferritic-austenitic microstructure, are used in a wide range of applications thanks to their high corrosion resistance and good mechanical properties. However, efficient and successful production and joining of DSS require precise control of processes and an in-depth understanding of the relations between composition, processing thermal cycles, resulting microstructures and properties.

   Abstract : Nanofabrication techniques were used to manufacture nanometer scale protein templates. The fabrication approach employs electron beam lithography (EBL) patterning on poly(ethylene glycol) (PEG) thiol (CH3O(CH2CH2O)17NHCO(CH2)2SH) self-assembled monolayers (SAM) on Au. READ MORE

7. 5. Raman and Fluorescence Spectroscopy of Single Molecules and Metal Particles

   Author : Jerk Bjerneld; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser-induced; single-molecule spectroscopy; surface-enhanced Raman scattering; nanoparticles;

   Abstract : Technological and conceptual advances have led to the realization of single-molecule spectroscopy. This permit detailed investigations of heterogeneous systems in fields ranging from condensed matter physics to biochemistry. It was recently discovered that surface-enhanced Raman scattering (SERS) can be used to study single molecules. READ MORE
