  1. 11. Modified cellulose synthesized by different deep eutectic solvents as an additive in paper making process

    University essay from Karlstads universitet

    Author : Shiniar Said Saleh; [2023]
    Keywords : green chemistry; dry strength additives; deep eutectic solvents; sodium periodate oxidation; charge density; dewatering; mechanical strength.;

    Abstract : The environmental concerns that come with the currently used traditional papermaking process where petroleum-based additives are used, has tempted researchers to study “green” additives by introducing environmentally friendly modifications of cellulose as an additive in the papermaking process. This thesis will spin further on that by producing additives with different charge densities and focus on to incorporate an etherification reaction into potentially greens systems based on non-toxic and readily biodegradable deep eutectic solvent (DES).

  3. 12. Crisis Management in Theory and Practice: How and Why Organizations Work the Way They Do

    University essay from Jönköping University/Internationella Handelshögskolan

    Author : Linus Johansson; Lukas Pihl; [2023]
    Keywords : crisis management; traditional crisis management; resilience; robustness; antifragility; contingency theory; Scandinavian institutionalism; organizational types;

    Abstract : We live in a turbulent environment in which the unpredictability of crises is unprecedented. Following this, crisis management literature has shifted from traditional planned and process-based approaches to contemporary concepts that emphasize reactivity. READ MORE

  4. 13. Desulphurisation of cement flue gases

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Ellen Sjöstrand; [2023]
    Keywords : Flue Gas Desulphurisation; FGD; gypsum; cement;

    Abstract : Flue gas desulphurisation (FGD) is a crucial method to minimise the SO2 emissions from industrial processes. The FGD system utilise an alkaline sorbent to remove SO2 from the flue gases. Calcium in form of limestone is a commonly used sorbent where gypsum is produced asa by-product. READ MORE

  5. 14. Comparison of different approaches for modelling the beam-target reactivity in fusion plasmas

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Marcus Petersson; [2022]
    Keywords : JET; Fusion; Fusion Diagnostics; Computational Physics; Modelling; NBI; Beam-Target Reactivity;

    Abstract : Fusion research has been an ongoing research endeavour for many decades and it has the potential of providing an important part in the future of energy production. An important part of this process is to understand and control the various heating systems of the reactor where one of the most important systems being the Neutral Beam Injector (NBI) which injects particles at high velocities into the plasma.

  6. 15. Unspecific interactions in different batch variations of agarose based base matrices at different NaCl concentrations.

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

    Author : Kejvan Ghofranpanah; [2022]
    Keywords : Lysozyme; hydrophobicity; size exclusion chromatography; NaCl concentrations; isocratic elution; Lysozym; hydrofobicitet; size exclusion chromatography; NaCl-koncentrationer; isokratisk eluering;

    Abstract : Size exclusion chromatography (SEC) separates molecules based on their actual size rather than their molecular weight. This indicates that the smaller a molecule is, the longer it will be held in the column since it can penetrate the pores more effectively than a bigger molecule, resulting in a longer retention time, whereas the larger molecule has a shorter retention time.
