16. Temperature-dependent waterbinding on potassiumbirnessite : A potential sorbent for atmospheric water harvesting
Kandidat-uppsats, Umeå universitet/Kemiska institutionenSammanfattning : The nanolayered manganese oxide birnessite (MnO2) is a naturally occurring mineralin soils and sediments. Its ability to capture and store water within its interlayers, andits great solar absorptivity, could be a part of the solution to global water shortage. LÄS MER
17. Investigation of Heat Treatment and Quenching Cycles on Microstructure and Mechanical Properties of Hadfield Steel
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Hadfield steel is a material used in different industrial application, when a good resistance to severe impact loads and abrasion is expected. Its high ductility, high toughness, good work hardening capacity and high fatigue resistance make it especially suitable for theses conditions. LÄS MER
18. Determination of bio-accessible amounts of metal trace elements in baby food using In vitro artificial digestion
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Prefabricated baby food is under strict EU legislation by Commission Regulation (EC) 1881/2006 Setting maximum levels for certain contaminants in foodstuffs regarding the maximum allowed content of potentially harmful elements. For potentially toxic trace elements the regulated maximum content is regulated for lead, cadmium, mercury, inorganic tin, inorganic arsenic, cesium, copper and manganese. LÄS MER
19. High entropy oxide electrodes with ionic liquid electrolyte
Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : Metal-based high entropy oxides are considered promising electrode materials for use in Li- ion batteries. In this work, the most widely studied high entropy oxide Mg0.2Ni0.2Cu0. LÄS MER
20. Multivariable analysis for studies of the origin of residual peroxide
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : På pappersmaskin 11 i Hallsta pappersbruk tillverkas högglansigt papper som bleks med väteperoxid. Om väteperoxiden som finns kvar efter blekningen, kallat restperoxid, kommer ut på pappersmaskinen sliter detta på termovalsarna, vilket påverkar slutprodukten. LÄS MER
