1. Improvement of Pt-based catalyst supported on CeZrO2 used for the high-temperature water-gas shift reactionMaster-uppsats, Lunds universitet/Kemiteknik (CI)
Sammanfattning : The iron-chromium (Fe/Cr) catalyst is used for high-temperature water-gas shift (HT WGS) reaction. A major concern using the Fe/Cr catalyst is that it contains hexavalent chromium (Cr+6) which is a potent carcinogen causing health and environmental issues. LÄS MER
2. Comparative LCA between biobasedand petroleum-basedlubricants : Identification of data gaps to consider whenproviding decision supportMaster-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik
Sammanfattning : This report aimed to provide decision support regarding a potential switch from a petroleum-based lubricant to a bio-based lubricant. The support was supposed to be provided based on a comparative lifecycle assessment (LCA) adjusted to encompass the specific situation of the company under consideration. LÄS MER
3. Enhancement of Phenol Formaldehyde Adhesive with Crystalline Nano CelluloseUppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för skog och träteknik (SOT)
Sammanfattning : Abstract The wood industries to this day use almost exclusively petroleum derived adhesives that are based mainly on the reaction of formaldehyde with urea, melamine or phenol. These adhesives have low cost and good adjustable properties which makes it hard for bio-based alternatives to compete. LÄS MER
4. Glucosinolates in Lepidium campestre : method development and analysisMaster-uppsats, SLU/Department of Molecular Sciences
Sammanfattning : Field cress (Lepidium campestre) is today not a domesticated crop for public consumption. Lepidium campestre is a relative to rapeseed (Brassica napus) and both are producing oil. LÄS MER
5. A comparison between the effects of polylactic acid and polystyrene microplastics on Daphnia magnaMaster-uppsats, Stockholms universitet/Institutionen för miljövetenskap och analytisk kemi
Sammanfattning : The effects of microplastics on zooplankton are an increasing environmental concern. Both primary microplastics that are produced as constituents of cosmetic products, as well as secondary microplastics that are formed by degradation of larger plastic debris, are ubiquitous in aquatic environments.
