  4. 2. Development of in silico methods to aid chemical risk assessment : focusing on kinetic interactions in mixtures

    Author : Elena Golosovskaia; Patrik L. Andersson; Stefan Örn; Patrik Rydén; Ester Papa; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QSAR; physiologically based kinetic; PBK; zebrafish; ADME; mixture; bisphenols; PFAS; toxicokinetics; environmental science; miljövetenskap; Toxicology; toxikologi;

    Abstract : The environment and biota are constantly exposed to numerous chemicals through contaminated food, soil, water, and air. These chemicals can be taken up and distributed to reach sensitive tissues where they may cause various effects. Many of these chemicals lack data on their environmental and human health effects.

  5. 3. Granular Materials for Transport Infrastructures : Mechanical performance of coarse–fine mixtures for unbound layers through DEM analysis

    Author : Ricardo de Frias Lopez; Johan Silfwerbrand; Jonas Ekblad; Björn Birgisson; Jörgen Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; discrete element method; force distribution; gap-graded mixtures; granular materials; particle-scale behaviour; permanent deformation; resilient modulus; soil fabric; binära blandningar; diskreta elementmetoden; grusmaterial; kraftöverföring; verkningssätt på partikelnivå; permanent deformation; skelettstruktur; styvhet; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Granular materials are widely used as unbound layers within the infrastructure system playing a significant role on performance and maintenance. However, fields like pavement and railway engineering still heavily rely on empirically-based models owing to the complex behaviour of these materials, which partly stems from their discrete nature.

  6. 4. Phase Equilibrium-aided Design of Phase Change Materials from Blends : For Thermal Energy Storage

    Author : Saman Nimali Gunasekara; Viktoria Martin; Justin NingWei Chiu; Torsten Fransson; Ana Ines Fernandez; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage TES ; phase change material PCM ; phase diagram; congruent melting; compound; solid solution; eutectic; peritectic; Energy Technology; Energiteknik; Teknisk materialvetenskap; Materials Science and Engineering; Chemical Engineering; Kemiteknik;

    Abstract : Climate change is no longer imminent but eminent. To combat climate change, effective, efficient and smart energy use is imperative. Thermal energy storage (TES) with phase change materials (PCMs) is one attractive choice to realize this. READ MORE

  7. 5. Wood hydrolysates- New concepts in renewable material design

    Author : Yingzhi Zhu Ryberg; Ulrica Edlund; Ann-Christine Albertsson; Dufresne Alain; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood hydrolysate; oxygen barrier; coatings; films; hemicellulose; lignin; CMC; chitosan; HSP; PALS; spray drying; SEM with tensile test; glyoxal crosslinking.; vedhydrolysat; syrebarriäregenskaper; ytbeläggningar; filmer; hemicellulosa; lignin; CMC; kitosan; HSP; PALS; spraytorkning; SEM med dragprovning; glyoxal tvärbindning.;

    Abstract : Wood hydrolysates (WHs) are biomasses obtained in processes involving hydrothermal treatments of wood. WHs are rich in hemicelluloses and lignin. Instead of complicated extraction processes, such as precipitation, or extensive purification, this work utilizes the crude WHs. READ MORE
