1. 1. Kadmiumhalter i svensk tång

   Kandidat-uppsats, Lunds universitet/Livsmedelsteknik (kandidat); Lunds universitet/Livsmedelteknisk högskoleutbildning - YTH

   Författare :Jonathan Laike Ståhle; Emil Jonsson; [2022]
   Nyckelord :Cadmium; Sea weed; Sacchariana latissima; Ulva intestinalis; Fusus serratur; Boiling; AAS; ICP-OES; Food Technology; Agriculture and Food Sciences; Chemistry;

   Sammanfattning : Seaweed along the Swedish coast contains both proteins, fats, vitamins and minerals, and could be part of the food supply of the future. It could also be described as climate smart as seaweed does not need to be watered, fertilized, or take up land for cultivation. LÄS MER

3. 2. Making wood durable. A sustainable approachwith linseed oil

   Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Helena Olsson; [2019]
   Nyckelord :Linseed oil; Wood preservation; Nuclear Magnetic Resonance NMR ; Diffusion Ordered Spectroscopy DOSY ; Time-resolved oxidation study; Linolja; Bevarande träbehandling; Nuclear Magnetic Resonance NMR ; Diffusion Ordered Spectroscopy DOSY ; Oxidationstidsstudie;

   Sammanfattning : Linseed oil has been and is used for vast number of applications, such as in food and paint industry, and wood preservation. It is a good environmental choice, as it originates from renewable sources. Linseed oil is mainly a mixture of triglyceride of fatty acids, both saturated and mono- or polyunsaturated, which allows the oil to oxidize. LÄS MER

4. 3. Spectroscopic evaluation of stability and homogeneity of formulated lubricant

   Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Amir Vranjkovina; [2019]
   Nyckelord :Lubricants; Base oil; ICP-AES; FTIR; Method validation; Smörjmedel; Basoljor; ICP-AES; FTIR; Metodvalidering;

   Sammanfattning : Lubricant is a common name for a large group of products that are essential for almost every engine or other machinery equipment that include mechanical part movements. Their main application is reduction of the friction between two rubbing surfaces by interposing a lubricating film between them. LÄS MER

5. 4. Determination of element composition in CoffeeBricks before and after incineration

   Kandidat-uppsats, Uppsala universitet/Analytisk kemi

   Författare :Annika Fröling; [2015]
   Nyckelord :ICP-AES; CoffeeBricks; briquettes;

   Sammanfattning : The purpose for this study was to determine the element composition in CoffeeBricks before and after incineration. The difference between element composition in CoffeeBricks (barbecue briquettes made out of spent coffee grounds) and regular barbecue briquettes was also evaluated in this study. LÄS MER

7. 5. How does urban discharge affect a lake in a recreational area in central Sweden? : a comparison of metals in the sediments of three similar lakes

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Madelene Holmblad; [2014]
   Nyckelord :Geografi; naturgeografi och ekosystemanalys; tungmetaller; smältvatten; sediment; Geography; physical geography and ecosystem science; heavy metals; melt water; sediments; Earth and Environmental Sciences;

   Sammanfattning : Metal contamination of lakes can bring negative effects to aquatic biota, and to the general health of the ecosystem. Urban discharge is a known source of common metals. In cold regions, snow disposal sites further enhances the risk of contaminating recipient lakes, due to accumulation of pollutants. LÄS MER
