    Keywords : Microsystems; harsh environments; high pressures; high temperatures; supercritical microfluidics; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Abstract : When operating microsystems in harsh environments, many conventionally used techniques are limiting. Further, depending on if the demands arise from the environment or the conditions inside the system, different approaches have to be used. READ MORE

  4. 2. Industrial Application of Sulfur Concrete An Environment-friendly Construction Material

    Author : Amon Raphael Makenya; KTH; []
    Keywords : Sulfur binder; Chempruf modifyer; Sulfur Concrete SC ; Durability; SC market survey; SC Applications; Environment.;

    Abstract : Sulfur Concrete (SC) is a thermoplastic constructionmaterial, of mineral aggregates and modified sulfur as binder.Elemental sulfur has now a low smelting point (120oC) and appears in two solid allotropic forms,separated by considerable contraction. Hence, the need formodification to delay the transition. READ MORE

  5. 3. Energy Harvesting and Energy Storage for Wireless and Less-Wired Sensors in Harsh Environments
