  1. 21. Mesoporous magnesium carbonate as a drug delivery vehicle for stabilising amorphous drugs and regulating their release rate

    Författare :Peng Zhang; Maria Strømme; Niklas Hedin; Uppsala universitet; []
    Nyckelord :mesoporous; magnesium carbonate; drug delivery; solubility enhancement; bioavailability; pharmacokinetics; diffusion release; controlled release; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

    Sammanfattning : In today’s drug discovery, the number of candidate drugs based on new molecular entities with poor aqueous solubility is increasing. Since poor aqueous solubility of an active pharmaceutical ingredients (APIs) is associated with low bioavailability and thus limite their therapeutic effect, this is often a great challenge in the development of new drugs when oral administration is the preferred route of administration.

  3. 22. Designing out waste - Exploring barriers for material recirculation

    Författare :Isabel Ordonez Pizarro; Chalmers tekniska högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste sorting; sustainable development; Water; Waste; Urban; waste management; Resources; resource recovery; ​Recycling; designing with waste; recycling;

    Sammanfattning : This doctoral thesis has investigated what hinders material recirculation in society, to later suggest possible ways to support material recirculation in the future. Since material recirculation is proposed as a way to use waste materials for new production, it was deemed relevant to investigate two separate case studies that enabled recirculation from production systems and waste management.

  4. 23. Generic Modelling of Integrated Material Flows and Energy Systems

    Författare :Johan Sundberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This dissertation describes MIMES, a nonlinear model for the optimization of linked material and energy flow systems. The model is generic, intended for systems that can be described by material and energy balances. LÄS MER

  5. 24. Energy efficiency in heritage buildings : Conservation approaches and their impact on energy efficiency measures

    Författare :Tomas Örn; Agatino Rizzo; Sofia Lidelöw; Andrea Luciani; Elena Lucchi; Luleå tekniska universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency heritage buildings; Arkitektur; Architecture;

    Sammanfattning : The impeding climate change challenge urges for a reduction of energy use in the built environment. Buildings account for nearly 40% of the total energy use and about 35% of the greenhouse gas emissions in Europe. LÄS MER

  7. 25. Design Beyond Interventions – Supporting Less Energy-reliant Activities in the Everyday

    Författare :Anneli Selvefors; Chalmers tekniska högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Activities; Energy use; Enabling preconditions; Design for Sustainability; Everyday life; Energy conservation;

    Sammanfattning : This thesis addresses challenges and opportunities for product design to contribute to domestic energy conservation. The overall aim of the thesis is that of increasing the understanding of people’s energy use and their use of energy-reliant artefacts in the everyday in order to propose ways of supporting energy conservation through design.
