1. 16. Investigation of the binding effect of fungal fiber (grown on apple pomace) in the formation of lyocell nonwoven textiles and their potential applications

   Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Författare :Xue Luo; [2021]
   Nyckelord :lyocell; nonwovens; binder; filamentous fungi; wet-laid; fungal microfibers; apple pomace; cellulose;

   Sammanfattning : This project combines nonwoven technology, biological technology and food waste management and seeks for this feasibility to use fungal microfiber (FM) as a binder for lyocell pro-duction and the characterizations for possible applications. Rhizopus delemar was cultivated apple pomace in liquid-state fermentation to obtain mycelia biomass. LÄS MER

3. 17. Optical characterisation of AAO/CsPbBr3 perovskite nanocomposites

   Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Författare :Klára Nováková; [2021]
   Nyckelord :perovskite; scintillator; optoelectronics; semiconductor; X-ray detection; Physics and Astronomy;

   Sammanfattning : Direct bandgap metal lead halide perovskites offer promising optoelectronic properties desirable in a wide range of applications including photodetection. However, the incomplete and poor understanding of the photophysical processes taking place in these materials, along with their poor stability, is the bottleneck for optimisation and further development of metal halide perovskite devices.

4. 18. Modelling the impacts of organic matter quality on soil carbon turnover and storage : continued testing of a novel dual-pore model against data collected from a long-term study site in Offer, Sweden

   Master-uppsats, SLU/Dept. of Soil and Environment

   Författare :Mikael Sasha Dooha; [2021]
   Nyckelord :soil; soil organic matter; carbon; carbon sequestration; tillage; land-use; soil structure; porosity; modelling; humification;

   Sammanfattning : As we look for solutions to the worsening climate crisis, carbon sequestration has become a popular strategy to mitigate CO2 emissions. Carbon models are used to predict or emulate changes in future soil organic carbon (SOC) stocks, but most fail to account for the influence of pore size on soil structure and SOC storage. LÄS MER

5. 19. Convolutional neural networks for semantic segmentation of FIB-SEM volumetric image data

   Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

   Författare :Fredrik Skärberg; [2020-11-26]
   Nyckelord :Deep learning; convolutional neural networks; image analysis; semantic segmentation; focused ion beam scanning electron microscopy; porous materials; controlled drug release;

   Sammanfattning : Focused ion beam scanning electron microscopy (FIB-SEM) is a well-established microscopy technique for 3D imaging of porous materials. We investigate three porous samples of ethyl cellulose microporous films made from ethyl cellulose and hydroxypropyl cellulose (EC/HPC) polymer blends. LÄS MER

7. 20. Linkage of Macro- and Micro-scale Modelling Tools for Additive Manufacturing

   Master-uppsats, KTH/Materialvetenskap

   Författare :Julia Sjöström; [2020]
   Nyckelord :Maraging steel; selective laser melting; temperature evolution; macro-scale modelling; segregation; ICME.;

   Sammanfattning : Additive manufacturing methods for steel are competing against commercial production in an increasing pace. The geometry freedom together with the high strength and toughness due to extreme cooling rates make this method viable to use for high-performance components. The desirable material properties originate from the ultrafine grain structures. LÄS MER
