  2. 21. Microstructure and properties of welds in the lean duplex stainless steel LDX 2101

    Author : Elin M. Westin; John Ågren; Hannu Hänninen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Duplex stainless steel; welding; HAZ; nitrogen; manganese; microstructure; austenite formation; phase balance; precipitates; element distribution; segregation; depletion; solidification; pitting corrosion resistance; solidification; element loss; evaporation; deposition; weld oxide; thermo-mechanical simulation; thermodynamic modelling; EPMA; XPS; post-weld cleaning; pickling; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : Duplex stainless steels can be very attractive alternatives to austenitic grades due to their almost double strength at equal pitting corrosion resistance. When welding, the duplex alloys normally require addition of filler metal, while the commodity austenitic grades can often be welded autogenously. READ MORE

  4. 22. Functionalization and Characterization of Carbon Based Nanomaterials for Electronics, Composite and Biomedical Applications

    Author : Nan Wang; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; carbon nanomaterials; flexible electronics; hybrid nanowires; functionalization; graphene;

    Abstract : Surface functionalization of nanomaterials to combine different material’s properties together opens up unlimited possibilities for both academic research and industrial applications. In this thesis, flexible and scalable chemical approaches to functionalize carbon nanomaterials (CNMs) are developed for different applications, including electronics, composite and biomedical applications.

  5. 23. Solution-Processable Conductive Graphene-Based Materials for Flexible Electronics

    Author : Jie Zhao; Zhi-Bin Zhang; Shi-Li Zhang; Matti Mäntysalo; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; Graphene oxide; Silver; Copper; Composite; Conductive inks; Flexible electronics; Printed electronics; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : This thesis work explores electrical conductors based on few-layer graphene flakes as an enabler for low-cost, mechanically flexible, and high-conductivity conductors in large area flexible and printed electronic devices. The flakes are deposited from aqueous solutions and processed at low temperature. READ MORE

  6. 24. Mesoporous Materials for Fast Charging Electrochemical Energy Storage

    Author : Giulio Calcagno; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; electrochemical energy storage; redox-active electrolytes; mesoporous carbon; hybrid supercapacitors; fast charging storage; ordered mesoporous materials; mesoporous titanium dioxide; lithium-ion battery;

    Abstract : High performing electrochemical energy storage (EES) devices are needed to cope with the increasing energy requirements of modern society. Electrode materials must store lots of energy, charge/discharge fast and be environmentally friendly. READ MORE

  7. 25. Chimeric gene delivery vectors : Design, synthesis, and mechanisms from transcriptomics analysis

    Author : Moataz Dowaidar; Ülo Langel; Sandrine Sagan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptides; magnetic nanoparticles; graphene oxide; autophagy; siRNA; SCO; QSAR; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : Delivery of nucleic acid is a promising approach for genetic diseases/disorders. However, gene therapy using oligonucleotides (ONs) suffers from low transfection efficacy due to negative charges, weak cellular permeability, and enzymatic degradation. READ MORE
