    Abstract : In most of the industrialised world, the proportion of older and retired people in the population is continuously increasing. This will have budgetary implications for maintaining the welfare state, because the active working section of the population must fund the non-active and old population. READ MORE

  4. 2. Macro-, Micro- and Nanospheres from Cellulose : Their Preparation, Characterization and Utilization

    Author : Christopher Carrick; Lars Wågberg; Derek Gray; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose; sphere; capsule; functionalization; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The structure of a polymeric material has a great influence in many fundamental scientific areas as well as in more applied science, since it affects the diffusion, permeability, mechanical strength, elasticity, and colloidal properties of the materials. The results in this thesis demonstrate that it is possible to fabricate solid and hollow cellulose spheres with a cellulose shell and encapsulated gas, liquid or solid particles and with a sphere size ranging from a few hundreds of nanometres to several millimetres, all with a tailored design and purpose.

    Abstract : Today, the growing and aging population, and the rise of new global threats on human health puts an increasing demand on the healthcare system and calls for preventive actions. To make existing medical treatments more efficient and widely accessible and to prevent the emergence of new threats such as drug-resistant bacteria, improved diagnostic technologies are needed.

  6. 4. Micro-Structure Modelling of Acoustics of Open Porous Material

    Author : Eva Lundberg; Peter Göransson; Per Wennhage; Ulf Orrenius; Camille Perrot; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustics; porous material; flow resistivity; micro-structure; anisotropic; foam; strut; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : Transportation is a large and growing part of the world’s energy consumption. This drives a need for reduced weight of rail vehicles, just as it does for road vehicles. In spite of weight reductions, the vehicle still has to provide the same level of acoustic comfort for the passengers. READ MORE

  7. 5. Numerical study of flow boiling in micro/mini channels

    Author : Qingming Liu; Björn Palm; Satish Kandlikar; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical; boiling; micro channel; phase change.; Energiteknik; Energy Technology;

    Abstract : Boiling phenomena in micro scale has emerged as an interesting topic due to its complexity and increasing usage in micro electronic and mechanical systems (MEMS). Experimental visualization has discovered five main flow regimes: nucleate boiling, isolated bubbles, confine bubbly flow, elongated bubbly (or slug) flow, and annular flow. READ MORE
