  1. 6. User-Centred Design and Technology-Mediated Services- Identifying and Addressing Challenges by Analysing Activities

    Författare :Oskar Rexfelt; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; technology-mediated services; product development; user requirements; User-centred design; service development; user studies;

    Sammanfattning : User-centred design has a focus on designing products to satisfy user needs rather than emanating from a technological starting point. Understanding user needs when developing products is considered a key component to achieve market success today.User-centred design is almost always described as a way to design products that satisfy user needs.

  3. 7. Guiding Sustainability Transitions: Backcasting, Experimentation and Social learning

    Författare :Johan Larsson; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sustainability transitions; transdisciplinarity; reflexive governance; experimentation; backcasting; Education for Sustainable Development ESD ; social learning;

    Sammanfattning : Sustainability challenges including climate change, social injustice, resource depletion and biodiversity loss are becoming increasingly apparent. These challenges can be understood as partly resulting from unsustainable socio-technical systems in society, assumed to require transitions to become sustainable in time. LÄS MER

  4. 8. Up close and personal: How relational dynamics in founding teams are shaped by the context of entrepreneurship

    Författare :Pamela Nowell; Chalmers tekniska högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; family theory; trust; close relationships; entrepreneurship; founding team; new venture team;

    Sammanfattning : Despite increased interest in the phenomena of team-based entrepreneurship, we still don’t know why some teams are more effective than others in their entrepreneurial pursuits. In fact, scholars acknowledge that we have yet to get a firm grasp on what teams ‘are’ in this unique work context, not least because their emotional and relational dynamics remain understudied.

  5. 9. Ultra-sensitive measurements of magnetically labelled RCA products in a microfluidic channel using a high-Tc SQUID

    Författare :Sobhan Sepehri; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diagnostics.; high-Tc SQUID; biosensor; magnetic nanoparticle; rolling circle amplification; magnetic bioassay;

    Sammanfattning : The development of a nucleic acid (deoxyribonucleic acid (DNA), ribonucleic acid (RNA)) bioassay based on magnetic nanoparticles (MNPs) with a high-Tc superconducting quantum interference device (SQUID) gradiometer as a magnetic readout is described. The specific binding of the MNPs to the target DNA molecules changes the MNPs size distribution and, therefore, the relaxation dynamics and is measured by magnetic ac susceptometry. LÄS MER

  7. 10. Innovations in nanomaterials for proton exchange membrane fuel cells

    Författare :Robin Sandström; Thomas Wågberg; Ludvig Edman; Florian Nitze; Licheng Sun; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fuel Cells; Membrane Electrode Assembly; Oxygen Reduction Reaction; Platinum alloy catalyst; Nanoparticles; Gas Diffusion Electrode; Proton Exchange Membrane; Materials Science; materialvetenskap; fasta tillståndets fysik; Solid State Physics;

    Sammanfattning : Hydrogen technologies are rapidly receiving increased attention as it offers a renewable energy alternative to the current petroleum-based fuel infrastructure, considering that continued large-scale use of such fossil fuels will lead to disastrous impacts on our environment. The proton exchange membrane fuel cell should play a significant role in a hydrogen economy since it enables convenient and direct conversion of hydrogen into electricity, thus allowing the use of hydrogen in applications particularly suited for the transportation industry.
