  1. 21. Dye sensitzation effects on lanthanide upconversion nanoparticles

    University essay from KTH/Fysik

    Author : Dag Albin Bäck; Andreas Jörgensen; [2022]
    Keywords : Dye sensitization; lanthanide upconversion nanoparticles; upconversion nanoparticles; UCNP; IR806;

    Abstract : In this report we studied the properties of the dye IR806 and possible mechanisms of the dye sensitization effect on ytterbium-erbium co-doped upconversion nanoparticles. We found that the dye IR806 has two primary emission peaks in the NIR spectral range at around 850 nm and at around 950 nm. READ MORE

  2. 22. Life cycle analysis and comparison of climate impact for two alternative floor systems for increased weight in high-rise timber buildings

    University essay from KTH/Byggnadsmaterial

    Author : Nir Kedem; [2022]
    Keywords : Life cycle assessment; LCA; Anavitor; Environmental impact; Building materials; Timber; Concrete; Gravel; Adding weight system.;

    Abstract : The aim of this Master Thesis is to investigate and quantify the climate impact for two floor system alternatives for the Cederhusen project, that is the 8 floors timber-based buildings located at Sankt Eriksplan in Stockholm. The overall motivation for this study is the fact that the construction industry is a major contributor to the total amount of the global greenhouse gas emissions. READ MORE

  3. 23. Contrastive Multimodal Image Representations for Deformable Image Registration

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Love Nordling; [2022]
    Keywords : ;

    Abstract : Image registration is the process of finding correspondences between images of the same or of similar scenes. Multimodal image registration is the specific case where the images are captured with different imaging systems. READ MORE

  4. 24. Real-time characterization of fuel by Near-Infrared spectroscopy : Quantitative measurements of moisture content, ash content, heating value, and elemental compositions in solid biofuel mixtures

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Kajsa Edlund; Ali Ahmad Shahnawazi; [2021]
    Keywords : NIR; spectroscopy; solid biofuel mixtures; moisture content; ash content; heating value; elemental composition; boiler; CHP pant; CCS; CO2; emissions; NIR; spektroskopi; fasta biobränsleblandningar; fukthalt; ask innehåll; värmevärde; elementär komposition; panna; kraftvärmeverk; CCS; CO2; utsläpp;

    Abstract : The global energy demand supplies mainly from fossil fuels, which is neither sustainable nor environmentally friendly and aims to global warming. Therefore, both more investments in renewable energy sources such as bioenergy are required, as well as new technologies such as carbon capture and storage (CCS) to handle the emissions from existing combined heat and power (CHP) plants.

  5. 25. Study of solution-based Cs0.1FA0.9Pb(I0.9Br0.1)3 perovskite deposition with scalable technology for solar cell production : Characterization of optical properties and function of the solar cell

    University essay from Uppsala universitet/Fysikalisk kemi

    Author : Tasnim Laskar; [2021]
    Keywords : ;

    Abstract : Climate change is one of the greatest challenges of the 21st century and is the reason for several environmental changes on earth. One reason behind climate change includes the rise ingreenhouse gas emissions in the atmosphere due to the burning of coal, gas and oil, i.e. fossil fuels. READ MORE
