1. 1. From Ocean to Table: Microplastic contamination in Nordic salts

   Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

   Författare :Anna Nyika; [2023]
   Nyckelord :Microplastic MP ; MP pollution; plastic pollution; sea salt; rock salt; Nordics; Iceland; Denmark; plastic waste management; human health; marine environment.; Earth and Environmental Sciences;

   Sammanfattning : Large amounts of plastic in the oceans originate from mismanaged plastic waste, and microplastics (MPs) are the most common type of waste. They can be found in household products, such as sea salts. Therefore, monitoring pollution levels is essential to improve marine health and food safety. LÄS MER

3. 2. Explorative Scenarios for Future Lithium Supplies and Demand

   Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Aksel Rahman; [2023]
   Nyckelord :lithium mining; lithium future production; Gompertz models; Richards models; Logistic models;

   Sammanfattning : Because of its specific qualities, lithium is a key element for making lithium-ion batteries, which is of great relevance since the battery sector is the fastest growing user of lithium to date and with the transition towards a fully electrified transportation sector due to the current climate agenda and an even bigger increase in demand for lithium is anticipated for the coming decades. The two main sources for lithium to date are mines and brines, with brine water composing around 87 % of the world’s lithium reserves in terms of contained lithium. LÄS MER

4. 3. Sweet and Salty: Colonial and Modern Corporate Commodity Exploitation in Northeastern Brazil

   Master-uppsats, Lunds universitet/Mänskliga rättigheter

   Författare :Flavia Copia Sperandio; [2022]
   Nyckelord :modern corporation; sugar cane monoculture; coloniality; rock salt mines; extractivism; Brazil; decolonial theory; business human rights.; History and Archaeology;

   Sammanfattning : This thesis is a historical comparative analysis of the social and environmental impacts of past colonial exploitation and the modern corporate extraction and exploitation of natural resources and commodities. The thesis examines these issues through the case studies of sugar monoculture in the Northeast region of colonial Brazil (16th and 17th Century) and the sinking of Maceió (also in Northeastern Brazil) due to the corporate exploitation of rock salt mines (1976-2019).

5. 4. Electrochemical Behavior of the High Entropy Oxide (Mg,Co,Ni,Zn)1-xLixO (x=0,35)

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

   Författare :Rasmus Sandström Kinnane; [2022]
   Nyckelord :high entropy oxides; lithium-ion battery; x-ray diffraction; scanning electron microscopy; cyclic voltammetry;

   Sammanfattning : Today's society is currently developing lithium-ion batteries to eventually replace the use of fossil fuels. High entropy oxides is a new type of material to use as an anode in the lithium-ion battery. These high entropy oxides may consist of a few different transition metals including lithium and oxygen.
