  1. 1. Everything you wanted to know about the TPA molecule adsorbed on Au(111)

    University essay from Uppsala universitet/Materialteori

    Author : Pamela H.W. Svensson; [2020]
    Keywords : Everything; you; wanted; to; know; about; TPA; molecule; adsrobed; on; Au; Au 111 ; Triphenylamin; Triphenylamine; DFT; Quantum; Espresso; QE; Generating; Pseudopotentials; NEXAFS; DOS; PDOS; simulations; organic; solar; cell; perovskite; HTM; HCH; NCH; FCH; PP; geometry; optimization;

    Abstract : The electronic properties of Triphenylamine (TPA) in gas phase and adsorbed on gold(111) have been simulated with Quantum Espresso using Density Functional Theory (DFT). To better understand how the presence of a gold surface affects sunlight absorption in the system, partial Density Of States (pDOS) and Near Edge X-ray Absorption Fine Structure (NEXAFS) of the system have been calculated.

  3. 2. Miljögifters påverkan på delfiners hälsa och överlevnad : individ och populationsnivå

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

    Author : Elvira Palmborg; [2016]
    Keywords : delfiner; miljögifter; PCB; DDT; PBDE; HCH; PFC; PAH; kadmium; kvicksilver; dolphins; environmental contaminants; cadmium;

    Abstract : Delfiner är utsatta för många antropogena hot, där en av dessa är miljögifter. Bioackumulering och biomagnifiering uppstår ofta på grund av delfinernas höga position i näringskedjan och miljögifternas persistens, vilket resulterar i höga nivåer av föroreningar i späck. Detta kan i sin tur leda till olika toxiska effekter. READ MORE

  4. 3. Atmospheric Deposition of Legacy and Emerging Persistent Organic Pollutants in Northern Sweden

    University essay from Kemiska institutionen

    Author : Seth Newton; [2011]
    Keywords : ;

    Abstract : Bulk atmospheric deposition samples using Amberlite IRA- 743 as an absorbent for hydrophobic pollutants were taken every two months for one year at two different locations in northern Sweden. A method was developed for the analysis of various legacy and emerging POPs in these samples based on GC-HRMS. READ MORE

  5. 4. Hypertrofisk kardiomyopati hos en familj brittiska korthårskatter

    University essay from SLU/Dept. of Clinical Sciences

    Author : Victoria Welander; [2008]
    Keywords : HCM; hypertrofisk kardiomyopati;

    Abstract : The objectives of this study was to examine the prevalence of hypertrophic cardiomyopathy in a family of British Shorthaircats to determine the mode of inheritance and to investigate if the disease was associated with a mutation in myosin binding proteinC (MyBPC3). The family comprised 28 cats, seven male and 21 females. READ MORE

  6. 5. Water and pollutant flows through the Mejdurechye Reservoir, Uzbekistan

    University essay from Institutionen för naturgeografi och kvartärgeologi (INK)

    Author : Alexander Koutsouris; [2008]
    Keywords : Central Asia; Uzbekistan; hydrology; Amudarya; Mejdurechye; water; water reservoir; pollutant;

    Abstract : Karakalpakstan, Uzbekistan, has faced water scarcity and low water during several years as a consequence of Uzbekistan’s extensive irrigation of cotton fields. The environmental status of the Mejdurechye Reservoir, which is the largest in the lower Amudarya Delta, is therefore of great local importance. READ MORE
