6. Optical properties of water absorbing textiles for camouflage
Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologiSammanfattning : Background matching, a form of camouflage, involves species developing patterns and coloration that closely resemble their environment. Humans have utilized camouflage and background matching, particularly in military applications, to reduce detectable characteristics, known as signatures. LÄS MER
7. Development and Optimization of Near-infrared spectroscopy
M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : With the growing demand for sustainable options, the existing sorting capacities are limiting the potential for fiber-to-fiber recycling. With the help of near-infrared spectroscopy (NIRS), automated sorting of textiles with high accuracy is possible due to the easy access for polymer identification. LÄS MER
8. Prediction of Plastic Fragments in Recycled Paper Using Near-Infrared Spectroscopy
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Sustainability has gained a lot of attention in the field of research. Researchers and consumers both prioritize sustainability and environmental issues over previously dominant materials, such as plastic. Packaging and disposable items that used to be made of plastic have largely been replaced with paper. LÄS MER
9. The use of hyperspectral sensors for quality assessment : A quantitative study of moisture content in indoor vertical farming
Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknikSammanfattning : Purpose: This research will study how hyperspectral sensoring can assess the moisture content of lettuce by monitoring its growth in indoor vertical farming. Research questions: “What accuracy can be achieved when using hyperspectral sensoring for assessing the moisture content of lettuce leaves grown in vertical farming?” “How can vertical farming contribute to sustainability in conjunction with integration of NIR spectroscopy?” Methodology: This study is an experimental study with a deductive approach in which experiments have been performed using the hyperspectral technologies singlespot sensor and the hyperspectral camera Specim FX17 to collect spectral data.

10. Processing techniques of perovskite solar cells : Properties depending on material and manufacturing
Kandidat-uppsats, Uppsala universitet/Fysikalisk kemiSammanfattning : This project investigates how different types of perovskite solar cells, differentiated by choice of materials and processing techniques, compares to each other regarding performance and characterization. The purpose of the project is to further develop perovskite solar cells and to improve the method of manufacturing for better performance. LÄS MER
