  1. 1. Levande begravd : kan klimatförändringar ge mjältbrandssporer nya förutsättningar?

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Johanna Cavell; [2019]
    Keywords : mjältbrand; sporer; klimatförändringar;

    Abstract : Mjältbrand är en dödlig sjukdom som varit känd under en lång tid och som drabbar både djur och människor. En av anledningarna till att mjältbrand är fruktad är bakteriens förmåga att sporulera vid icke gynnsamma förhållanden och persistera i jorden under en lång tid. READ MORE

  2. 2. Chemical Stabilization of Arsenic in Contaminated Soil under Low Redox Conditions

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Eva Smedborn Pausson; [2019]
    Keywords : ;

    Abstract : Remediation techniques for arsenic contaminated soil have previously focused mostly on the surface soil layers where aerobic conditions are prevalent. In this master thesis, chemical stabilization by adding zero-valent iron (Fe(0)) and calcium oxide (CaO) to an arsenic-contaminated soil under low redox conditions have been studied through up-flow percolation tests.

  3. 3. Theoretical study of anisotropic effects in crystal growth on the example of concrete and calcium oxalate monohydrate

    University essay from Lunds universitet/Kemiska institutionen

    Author : Vilhelm Ekberg; [2019]
    Keywords : anisotropic crystal growth; COM; C-S-H; PM6; ReaxFF$_{ textrm{SiO}}$; organizing molecular matter; nanochemistry; nanokemi; Chemistry;

    Abstract : While many crystals, both natural and artificial, grow isotropically, there are examples of crystals growing anisotropically. The aim of this theoretical study was to confirm the growth modes displayed by three different crystals, representing 3D, 2D and 1D structures. READ MORE

  4. 4. Transfer Printing and Cellulose Based substrates for modern Textile Printing

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Mona Mrad; [2019]
    Keywords : ;

    Abstract : Digital printing technology is a technique that has been growing since the 1990s and has a high growth potential when it comes to using different ink types and transfer printing techniques. In comparison to screen printing, digital transfer printing techniques have shown to consume less ink and water and are therefore considered to be a more environmentally friendly alternative for textile printing.

  5. 5. Experimental Study of Mineral Carbonation of Wollastonite for Increased CO2 Uptake

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik; KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Dina Babiker; Matilda Ahlstrand; [2019]
    Keywords : Concrete; Mineral Carbonation; CO2 Sequestration; Wollastonite; Calcium Silicate; Betong; Mineral karbonatisering CO2-sekvestrering; Wollastonit; Kalciumsilicat;

    Abstract : The cement and concrete industry stand for approximately 8% of the global CO2 emissions. The demand of concrete and cement is expected to increase rapidly with the growing world population and increased urbanization. This makes it of the utmost importance for the industry to try to mitigate its emissions. READ MORE
