  1. 1. Amorphous magnesium carbonate nanomaterials Synthesis, characterization and applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jiaojiao Yang; Uppsala universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high surface-to-volume ratio; nanoparticles; mesoporous; magnesium carbonate; amorphous drugs; supersaturated concentration; general adhesives; UV-shielding;

    Abstract : High surface-to-volume ratio materials, including nanoparticles and mesoporous materials, have a number of applications due to their large surface area and special structures. Traditional approaches for synthesizing high surface-to-volume ratio nanomaterials are often complicated, expensive or environmentally unfriendly. READ MORE

  2. 2. Metal Hydrogen Interaction and Structural Characterization of Amorphous Materials from first principles

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Robert Johansson; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrogen; vanadium; zintl; laves; strain; diffusion; amorphous; dft; molecular dynamics; md; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : In this thesis, first-principles calculations based on density functional theory have been employed to investigate metal hydrogen interaction in transition, p-block and rare earth metals. Furthermore, the accuracy of the stochastic quenching method was tested in describing the structure of amorphous Fe(1-x)Zrx. READ MORE

    Abstract : Structural characterization is essential for the understanding of the magnetic properties of thin films and multilayers. In this thesis, both crystalline and amorphous thin films and multilayers were analyzed utilizing transmission electron microscopy (TEM). READ MORE

  4. 4. On-site wastewater treatment Polonite and other filter materials for removal of metals, nitrogen and phosphorus

    University dissertation from Stockholm : KTH

    Author : Agnieszka Renman; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkaline materials; heavy metals; mechanisms; nutrient removal; sorption; speciation modelling; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik;

    Abstract : Bed filters using reactive materials are an emerging technology for on-site wastewater treatment. Chemical reactions transfer contaminants from the aqueous to the solid phase. Phosphorus is removed from domestic wastewater by sorption to filter materials, which can then be recycled to agriculture as fertilisers and soil amendments. READ MORE
