  1. 26. In conversation with simulation: The application of numerical simulation to the design of structural nodal connections

    Författare :Jens Olsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; 3D Printing; Design theory; Structural design; Structural efficiency; Simulation; Peridynamics; Force flux density; Nodal connections; Conceptual design; Steel structures; Design process; Digital design;

    Sammanfattning : The thesis explores methods for integration of structural analysis, design and production in a digital design environment. The somewhat ambiguous title implies the ambition to make such integration in relation to the explorative phase of the design process which is described by Donald Schön as having a conversational character.

  3. 27. Additive Manufacturing and Integration of 3D MEMS using Ultrafast Lasers and Magnetic Assembly

    Författare :Simone Pagliano; Frank Niklaus; Göran Stemme; Gijs Krijnen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; additive manufacturing; 3D printing; 3D micromachining; two-photon polymerization; MEMS; polyimide; ultrafast laser; laser micromachining; vertical integration; magnetic assembly; stochastic assembly; diminutive chips;

    Sammanfattning : The geometry of MEMS devices is limited by the technologies used to fabricate them. Today, microsystems are manufactured with patterning technologies that allow only for 2D and 2.5D geometries. LÄS MER

  4. 28. Osteocytes as indicators of bone quality - multiscale structure-composition characterisation of the bone-implant interface

    Författare :Furqan A. Shah; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D printing; apatite; biomaterials; biomineralisation; bone; bone quality; canaliculi; CoCr; collagen; electron beam melting; electron microscopy; implant; interface; in vivo; lacuna; micropetrosis; osseointegration; osteocyte; Raman spectroscopy; surface modification; Ti6Al4V; titanium; ultrastructure; whitlockite;

    Sammanfattning : By virtue of certain design features, bone anchored metal implants can be made to elicit a strong initial osteogenic response, i.e., the amount of bone formed. LÄS MER

  5. 29. Porous Sorbents for Environmental Applications and Selective Laser Sintering 3D Printing of Dosage Forms

    Författare :Michelle Åhlén; Ocean Cheung; Maria Strömme; Jonas Lindh; Christel Bergström; Carlos Grande; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metal-organic frameworks; zeolitic imidazolate frameworks; mesoporous magnesium carbonate; greenhouse gas capture; adsorption; adsorption kinetics; additive manufacturing; selective laser sintering; personalized medicines; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : The rising levels of greenhouse gas emissions from vehicular and industrial pollution constitute a serious concern not only for the environment but for our entire society. Traditional gas capture and separation techniques, such as amine scrubbing for CO2 gas separation, have been commonly used at a commercial scale, however issues relating to high costs and high energy requirements for sorbent regeneration have limited the efficiency of many of these techniques.

  7. 30. Transcalar Design : biological principles in architecture through computational design and additive fabrication

    Författare :Ana Goidea; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :HUMANIORA; HUMANITIES; architecture; additive manufacturing 3D printing ; additive manufacturing; biotechnology; Biofabrication; biodesign; generative design;

    Sammanfattning : Architecture is currently facing a period of transformational change which is driven by an increasing awareness of sustainability imperatives combined with technological advancements in the form of digitalisation of design and fabrication processes. These issues both introduce new layers of complexity and necessitate strategies to navigate them. LÄS MER
