1. 1. Exocomets in the β Pictoris system

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Klaudia Jaworska; [2024]
   Keywords : Physics and Astronomy;

   Abstract : Comets have been a source of fascination throughout the history of man. In recent years, advances in technology have opened up for the study of extrasolar objects, among them exocomets. The first exocomets were observed in the β Pictoris system almost 50 years ago and the system has been of interest ever since. READ MORE

3. 2. Synergistic fire- and mechanical effect of biochar and ammonium polyphosphate in epoxy composite

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Anton Olausson; Ludvig Jönsson; [2023]
   Keywords : Ammonium polyphosphate; Biochar; Composite; Epoxy; Synergistic effect;

   Abstract : Polymer composites are used in a varying extent and are challenging the use of traditional materials due to the push towards sustainable development. They have replaced steels and aluminum alloys in applications. READ MORE

4. 3. Characterisation of Poly(trimethylene carbonate) and f-BTI2g-TVTCN blends for the use in Biosensors

   University essay from KTH/Kemiteknik

   Author : Sara El Ghamri; Ed Kammeby; Herman Göransson; Arvid Stjerngren; [2023]

   Abstract : This report aims to study the degradation of poly(trimethylene carbonate) (PTMC) caused by the enzyme carboxylesterase in vitro. As well as to characterise polymer blends of f-BTI2g-TVTCN and poly(3-hydroxybutyric acid) as core components for organic electrochemical transistors (OETCs). READ MORE

5. 4. Experimental and computational analysis of the thermal degradation and the loss of strength of engineered wood-based panels

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Wickramasooriyage Devmini Kularatne; [2022]
   Keywords : Oriented strand board; thermal decomposition; mechanical degradation; heat transfer modelling; Technology and Engineering;

   Abstract : The current trends in the construction industry push toward materials that are more sustainable and environmentally friendlier than more traditional building materials such as concrete and steel. Timber and timber composites are one of the most popular materials on this list, due to both their mechanical strength and pleasant aesthetics. READ MORE

6. 5. Effects of plastic pollution on leaf litter decomposition in Swedish freshwater ecosystems : a field study addressing recently and globally emerging pollutants

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Martina Stangl; [2022]
   Keywords : Microplastics; Face masks; Ecosystem functioning; Leaf decomposition; Field study;

   Abstract : Plastic pollution is recognized as an increasing environmental problem, but few studies have addressed impacts on ecosystem functions, and very few have been conducted in the field. This study investigated the effects of polypropylene particles derived from disposable face masks on in-situ leaf litter decomposition processes in freshwater ecosystems. READ MORE
