  1. 1. Development of nitrogen-containing materials for capture and catalytic conversion of carbon dioxide to value-added chemicals

    Author : Thai Q. Bui; Jyri-Pekka Mikkola; Knut Irgum; William Siljebo; Riitta Keiski; Umeå universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCUS; PEHA; DBU; mesoporous melamine-formaldehyde; DMC; cyclic carbonate; flow reactor; Physical Chemistry; fysikalisk kemi; sustainable development; hållbar utveckling;

    Abstract : Anthropogenic carbon dioxide (CO2) emissions have become a critical environmental issue because a large amount of CO2 releasing into the atmosphere, particularly from the massive use of fossil fuels, is the major factor promoting the global warming and climate change. To mitigate the CO2 emissions, Carbon Capture, Utilization and Storage (CCUS) can be one of important solutions. READ MORE

  2. 2. Towards low-emitting and sustainable particle and fibreboards : Formaldehyde emission test methods and adhesives from biorefinery lignins

    Author : Venla Hemmilä; Stergios Adamopoulos; Luísa Maria Hora Carvalho; Linnéuniversitetet; []

    Abstract : High volumes, fast production speed, and low material costs have been historically the driving factors of the particle- and fibreboard industries. However, in recent years the fossil-fuel dependency and health issues of the formaldehyde-containing adhesives used in the production have gained attention from both legislators and consumers.

  3. 3. Immune cells in pregnant uterine mucosa : functional properties, cellular composition and tissue organization

    Author : Lucia Mincheva-Nilsson; Sten Hammarström; Rolf Kiessling; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immunologically privileged site; TCR γδ cells; CD56 cells; large granular lymphocytes; immunosuppression; cytokine; interleukin; lymphoid cell cluster; intraepithelial lymphocytes; glandular epithelium; immuno electron microscopy; pregnancy; decidua; lactoferrin; lactoferrin receptor; colostrum;

    Abstract : The pregnant uterus mucosa - decidua - is an "immunologically privileged" site. A semiallogeneic embryo is allowed to survive, develop, and grow while the same tissue implanted outside the uterus will be rejected. The decidua basalis, which participates in the placenta formation, is a tissue rich in lymphoid cells. READ MORE

  4. 4. Hip Revision Surgery : Identification of Genetic Markers and Evaluation of Novel Treatment Strategies

    Author : Anders Brüggemann; Nils Hailer; Hans Mallmin; Karl Michaëlsson; Olle Nilsson; Per Wretenberg; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Total hip arthroplasty (THA) is, despite its overall good outcome, for some patients followed by hip revision surgery. This seems in parts to be because of genetic susceptibility to revision surgery. The most common reason for revision surgery is aseptic loosening followed by periprosthetic joint infection and dislocation. READ MORE

  5. 5. Molecular Simulations of Microstructure, Thermodynamics, and Dynamics of Complex Liquid Mixtures at Interfaces and Confined Spaces

    Author : Qingwei Gao; Ji Xiaoyan; Nordholm Sture; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Abstract : In modern chemical engineering, process intensification is realised by introducing a nano- or micro-interface. The introduction of such an interface breaks the homogeneous nature of the fluid and forms a unique nano- or micro-interfacial structure, which has a significant impact on the properties of fluids.
