  1. 1. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : William Gulding; [2023]
    Keywords : Adsorption; D-Rainclean; metal removal; Reactive filter; stormwater treatment;

    Abstract : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. READ MORE

  3. 2. Characterization of NiMo catalysts with noble metal promoters

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Filip Hallböök; [2023]
    Keywords : Catalysis; Hydrodeoxygenation; TPR; NiMo-catalysts; Chemical engineering; Chemistry;

    Abstract : To be able to face the challenges brought on by climate change there is an urgent need to reduce the heavy dependence on fossil fuels. Bio-oil is one such renewable and carbon-neutral replacement that has shown promising potential. A key step in making bio-oil commercially feasible is improvements of the upgrading processes of the bio-oil. READ MORE

  4. 3. Nanoscale characterisation of model Ni-Mo catalyst active phases

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Jonas Elmroth Nordlander; [2022]
    Keywords : Ni-Mo catalysts; Hydrodeoxygenation; TEM; PXRD; Materials chemistry; Chemistry;

    Abstract : An important stepping stone in transitioning from a fossil-fuel based transportation system is the production of bio-fuels such as bio-oils. For bio-oils to be commercially viable, catalytic upgrading via hydrodeoxygenation is required, typically using Ni-Mo oxide or sulfide catalysts. READ MORE

  5. 4. Electrochemical corrosion analysis of nickel-based superalloys

    University essay from KTH/Yt- och korrosionsvetenskap

    Author : Robin Gonzalez; [2022]
    Keywords : Electrochemistry; corrosion; nickel; polarization; EIS; Elektrokemi; korrosion; nickel; polarisation; EIS;

    Abstract : Elektrokemisk korrosionsanalys av legeringar är en essentiell del av den större materialanalysen som måste utföras när en legerings lämplighet för en viss applikation evalueras. Nickelbaserade legeringar är kända för sin utmärkta korrosionsresistans, och de Ni-Cr-Mo-baserade legeringarna 59, 625, och 718 är också så kallade superlegeringar. READ MORE

  6. 5. ENSO teleconnections - Analysis of time lag between tropical Pacific sea surface temperature and climate and vegetation anomalies

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Jiri Navrátil; [2020]
    Keywords : Physical Geography and Ecosystem Analysis; ENSO; teleconnections; climate; NDVI; Earth and Environmental Sciences;

    Abstract : El Niño-Southern Oscillation (ENSO) affects weather and climate in regions spread all around the Earth via teleconnections. While quite a lot of research has been done on recognizing what regions are affected by these and what is the sign of the associated temperature, rainfall and vegetation anomalies, not that much attention has been paid to the timing of the impacts with respect to the ENSO state.
