  2. 1. Crack-junctions : Bridging the gap between nano electronics and giga manufacturing

    Author : Valentin Dubois; Göran Stemme; Christofer Hierold; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanotechnology; nanoelectronics; nanogap electrodes; molecular electronics; nanoplasmonics; crack-junctions; break junctions; nanowires; parallel fabrication; lithography; fracture; crack; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Obtaining both nanometer precision of patterning and parallel fabrication on wafer-scale is currently not possible in conventional fabrication schemes. Just as we are looking beyond semiconductor technologies for next-generation electronics and photonics, our efforts turn to new ways of producing electronic and photonic interfaces with the nanoscale.

  4. 2. A Quantum Chemical View of Molecular and Nano-Electronics

    Author : Jun Jiang; Yi Luo; Jim Greer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi;

    Abstract : This dissertation presents a generalized quantum chemical approach for electron transport in molecular electronic devices based on Green's function scattering theory. It allows to describe both elastic and inelastic electron transport processes at first principles levels of theory, and to treat devices with metal electrodes either chemically or physically bonded to the molecules on equal footing.

  5. 3. Technology for biocomputational devices based on molecular motors

    Author : Frida Lindberg; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular motors; Nanofabrication; Biocomputation; Nanostructures; Fysicumarkivet A:2019:Lindberg;

    Abstract : For many multivariable problems there are no efficient algorithms for finding solutions. To this day, conventional electronic computers mainly solve problems in a sequential manner. This sequential operation prevents problem-solving within a reasonable time-frame due to superpolynomial, and sometimes even exponential, time complexities. READ MORE

  6. 4. Function and targets of the Urm1/Uba4 conjugation machinery in Drosophila melanogaster

    Author : Behzad Khoshnood; Caroline Grabbe; Tor Erik Rusten; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drosophila; Urm1; Uba4; MOCS3; Tax; HTLV; Posttranslational modification; ubiquitin-like modifiers; UBL; PTM; JNK; neuromuscular junctions; signaling; molekylärbiologi; Molecular Biology;

    Abstract : Posttranslational modification (PTM) of proteins is essential to maintain homeostasis and viability in all eukaryotic cells. Hence, besides the sequence and 3D folding of a polypeptide, modification by multiple types of PTMs, ranging from small molecular groups to entire protein modules, adds another layer of complexity to protein function and regulation.

  7. 5. Molecular mechanisms of nerve-tumor interactions : the intersection of cancer and neurodevelopment

    Author : Luz Maria Gonzalez-Castrillon; Sara I Wilson; Daniel Öhlund; Nisha D’Silva; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Perineural invasion; cancer; PDAC; axonogenesis; neurodevelopment; spinal cord; axon guidance; bioinformatics.; biomedical laboratory science; biomedicinsk laboratorievetenskap;

    Abstract : A wide range of cancers throughout the body are characterized by high nerve density and invasion of cancer cells within the nerves, a process called perineural invasion (PNI). Work in the field has shown that blocking nerves in organs with tumors leads to improved disease outcomes suggesting that finding ways to block tumor nerves could lead to new treatment approaches.
