1. 1. Investigating the potential correlations between metal and metalloid concentrations and soil color : A Minor Field Study on the island province of Marinduque, Philippines

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Ivana Pia Saric Söderholm; Erik Readwin; [2023]
   Keywords : Marinduque; Metal and Metalloid; Nix Pro 2 Color Sensor; Philippines; Soil color; X-Ray Fluorescence XRF ; Filippinerna; Jordfärg; Marinduque; Metall och Metalloid; Nix Pro 2 Color Sensor; Röntgenfluorescens XRF ;

   Abstract : This study was carried out as a bachelor's thesis at KTH Royal Institute of Technology during the spring of 2023, investigating the correlation between the color with the concentration of various metal and metalloids (MMs) in the soil of Marinduque, The Philippines. With a history of mineral exploitation, notably copper and gold, the island has faced persistent environmental challenges, exemplified by the catastrophic waste spills in 1993 and 1996 that contaminated the Boac and Mogpog Rivers.

3. 2. Identification of Vanadium-Binding Ligands in White Wine

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Freja T Trybom; [2023]
   Keywords : Vanadium; LD converter slag; wine; food waste; recycling.;

   Abstract : Vanadin är en värdefull metall och kan lakas ur LD (Linz-Donawitz)-slagg med hjälp av vin. Ligander i vinet som lakar vanadin från LD-slagg studerades i denna rapport med mål att identifiera några av deras egenskaper såsom apparent molekylmassa och spektral information. READ MORE

4. 3. Synthesis and Characterization of NCN Pincer Nickel Complexes

   University essay from Lunds universitet/Kemiska institutionen

   Author : Joel Klarén; [2023]
   Keywords : Pincer complexes; Nickel; organometallic chemistry; synthesis; NCN Pincer Nickel Complexes; organic chemistry; Chemistry;

   Abstract : In this work, a series of nickel NCN complexes and ligands have been synthesized with the goal of determining whether they can perform so-called CO2-insertion reactions into Ni-C bonds. So far, only the synthesis of the Ni-Br precursor complexes to the previously mentioned Ni-C complexes have been synthesized. READ MORE

5. 4. Automatic Recycling Sorting Unit: A platform designed to sort glass, plastic and metal

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Anni Li; Agnes Agåker Karlsson; [2023]
   Keywords : Mechatronics; Recycling; Inductive sensor; Capacitive sensor; Loadcell; Mekatronik; Återvinning; Induktivsensor; Kapacitivsensor; Viktcell;

   Abstract : This report describes the design and construction of a tilting platform for sorting household waste, limited to plastic, glass, and metal. The platform utilizes a capacitive sensor to identify if an object is placed on the platform, an inductive sensor to detect metal, and a load cell to differentiate between plastic and glass based on their weight difference.

6. 5. Dependence of Degradation Mechanisms in Magnesium Alloys on Grain Orientation and Interfaces in 3D

   University essay from Lunds universitet/Materialteknik

   Author : Johan Ranstad; [2023]
   Keywords : Mg-Zn alloys; Diffraction contrast tomography; Isothermal Calorimetry; Immersion testing; Corrosion Rate; Microgalvanic coupling.; Technology and Engineering;

   Abstract : Magnesium alloys are promising candidates as biomedical implants. However, a good understanding of their degradation processes is lacking. In this work, degradation in two magnesium alloys were studied in a simple physiological-fluid electrolyte of H2O+0.9wt%NaCl, Mg-5wt%Zn (Z5) & Mg-5wt%Zn-0. READ MORE
