  2. 11. Strategies for Performance Improvement of Quantum Dot Sensitized Solar Cells

    Author : Jing Huang; Hans Ågren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; quantum dot sensitized solar cells; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : Quantum dot sensitized solar cells (QDSCs) constitute one of the most promising low-cost solutions that are explored for the world’s needs of clean and renewable energy. Efficient, low-toxic and stable QDSCs for large-scale applications have formed the subject for the solar cell research during recent years. READ MORE

  4. 12. Nuclear envelope protein interaction studies

    Author : Mohammed Hakim Jaffer Ali; Einar Hallberg; Anki Östlund-Farrants; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Samp1; Nuclear envelope; protein interactions; chemical crosslinking; proteomics; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : The nuclear envelope (NE) separating the nucleoplasm from cytoplasm consists of two concentric lipid membranes, the outer (ONM) and inner (INM) nuclear membranes, the nuclear pore complexes (NPCs) and an underlying nuclear lamina network. The INM contains more than 100 unique transmembrane proteins of which only a few have been characterized. READ MORE

  5. 13. Membrane morphology and homeostasis: An electron microscopy approach

    Author : Dimitra Panagaki; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nuclear envelope bud; AdipoR2; membrane homeostasis;

    Abstract : Biological membranes allow life as we know it to exist. Primarily assembled from lipids and proteins, their morphology and function can greatly vary between species or even within the same cell. They create physical boundaries, separating different cells from each other and forming functional compartments within the cells. READ MORE

  6. 14. Characterization of RNA exosome in Insect Cells : Role in mRNA Surveillance

    Author : Viktoria Hessle; Neus Visa; Maria Carmo-Fonseca; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cell nucleus; nuclear bodies; mRNA surveillance; cotranscriptional assembly; Rrp6; Rrp4; mRNP; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Abstract : The exosome, an evolutionarily conserved protein complex with exoribonucleolytic activity, is one of the key players in mRNA quality control. Little is known about the functions of the exosome in metazoans. We have studied the role of the exosome in nuclear mRNA surveillance using Chironomus tentans and Drosophila melanogaster as model systems. READ MORE

  7. 15. Increased Productivity of Ferrous Alloys Produced by Powder Bed Fusion - Laser Beam

    Author : Rasmus Gunnerek; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; additive manufacturing; process optimization; build rate; build speed; powder bed fusion – laser beam; porosity; low alloy steel; 316L stainless steel; productivity in AM;

    Abstract : Low production speeds limit wider adoption of powder bed fusion – laser beam (PBF-LB) in cost sensitive industries as it correlates directly with high production costs. The main process parameters such as scan speed, hatch distance and layer thickness can be scaled up to increase build speed, but it often comes at a trade off in lower quality, i. READ MORE
