    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Johanna Swanelius; [2022]
    Keywords : Microfibrillated cellulose; MFC; waxy maize starch; rheology; temperature; viscosity; complex viscosity; stready shear viscosity curve; amplitude sweep; dry content; dynamic rotational rheometer; Mikrofibrillerad cellulosa; MFC; vaxartad majsstärkelse; reologi; temperatur; viskositet; komplex viskositet; flödeskurva; amplitudsvep; torrhalt; dynamisk reometer;

    Abstract : Today, the focus lies on the state of the environment and how we can choose more sustainable alternatives to oil based materials. One material of interest is microfibrillated cellulose (MFC). READ MORE

  4. 3. Thermal Initiation of Energetic Materials Caused by Hot Fragments

    University essay from KTH/Matematik (Avd.)

    Author : Sirak Ghebreamlak; [2022]
    Keywords : Applied mathematics; computational mathematics; heat equation; thermal initiation; chemical kinetics; energetic materials; Tillämpad matematik; beräkningsteknik; värmeledningsekvationen; termisk initiering; kinetik; energetiska material;

    Abstract : The cause of unintentional initiations of energetic materials is an important area of study due to the risks that comes with storing energetic materials such as high explosives. The current models used to simulate the process of heating energetic materials by a hot metal fragment do not give reliable predictions. READ MORE

  5. 4. Unveiling structural heterogeneities in aqueous solutions using dynamic light scattering

    University essay from Stockholms universitet/Fysikum

    Author : Oskar Eklund; [2021]
    Keywords : ;

    Abstract : To investigate the existence  of  molecular heterogeneties in mixtures of DMSO-water, the dynamics were measured with the method of dynamic light scattering (DLS). Three different compositions (20 mol %, 33 mol% and 60 mol%) were included in the study and measured at room temperature (295 K) and for one composition (33 mol %) also a temperature dependence (from 295 K down to 263 K) was measured.

  6. 5. Control of marine plankton respiration : High temperature sensitivity at low temperatures influenced by substrate availability

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Katharina Amundsson; [2016]
    Keywords : plankton respiration; temperature; substrate; limiting factors; Q10; Baltic Sea;

    Abstract : Temperature dependence of marine plankton respiration is an important factor in understanding the function and changes in the ecosystem of the ocean. The aim of this study is to test the temperature sensitivity (Q10) of plankton respiration. The oxygen optode method was used to measure plankton respiration. READ MORE
