  4. 22. Towards the Improvement of Salt Extraction from Lake Katwe Raw Materials in Uganda

    Author : Hillary Kasedde; Pär Jönsson; Anders Tilliander; Eric Forssberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake Katwe; salt extraction; brine; evaporites; saltpan; characterization; evaporation - crystallization; solubility; Pitzer ’s ion - interaction model; PHREEQC software; dissolution kinetics; Avrami model.;

    Abstract : Uganda is well endowed with economic quantities of mineral salts present in the interstitial brines and evaporite deposits of Lake Katwe, a closed (endorheic) saline lake located in the western branch of the great East African rift valley. Currently, rudimentally and artisanal methods continue to be used for salt extraction from the lake raw materials. READ MORE

  5. 23. Swelling and Mechanical Properties of Polymer Gels: Salt, Macroion and Network Topology Effects

    Author : Samuel Edgecombe; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; volume decrease upon uniaxial extension; interpenetrating networks; loose-end effects; polydispersity effects; macroion deswelling; salt deswelling; polymer gels; polyelectrolyte gels; Physical chemistry; Fysikalisk kemi;

    Abstract : The work in this thesis concerns polymer gels, especially their swelling and mechanical properties modelled using a coarse-grained model of polyelectrolytes. The method used to study polymer gels was molecular simulation utilising the simulation package MOLSIM. READ MORE

  6. 24. Household salt as an emergency radiation dosemeter for retrospective dose assessments using optically stimulated luminescence

    Author : Maria Christiansson; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Optically stimulated luminescence OSL ; household salt; NaCl; retrospective dosimetry; accident dosimetry;

    Abstract : In the event of a radiation accident, it is crucial to make rapid estimates of the absorbed dose received by both emergency workers, so-called first responders, and members of the public. Today, only personnel in rescue teams responding to nuclear emergencies have access to individual dosemeters. READ MORE

  7. 25. New Reactivity in Diaryliodonium Salt Chemistry

    Author : Erika Linde; Berit Olofsson; Thomas Wirth; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; organisk kemi;

    Abstract : Diaryliodonium salts (Ar2IX) have emerged as versatile multi-purpose reagents with desirable properties such as easy accessibility, low toxicity and applicability under mild and metal-free reaction conditions. Despite displaying broad utility in arylations of both carbon and heteroatom nucleophiles, the overall sustainability of these protocols is compromised by featuring poor atom economy due to the formation of stochiometric iodoarene byproducts.
