  2. 16. Covalent functionalization of carbon nanomaterials for bioelectrochemical applications

    Author : Naoual Allali; Alexander Soldatov; Manuel Dossot; Victor Mamane; Silvia Giordani; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

    Abstract : Carbon nanotubes (CTNs) are renowned for their exceptional electronic and mechanical properties. Their structure can be considered as rolling up a graphene sheet along a specific crystallographic direction, leading to a 1D confinement of the electronic wavefunction of the delocalized electrons along the perimeter of the cylindrical structure thus obtained.

  4. 17. On the role of ppGpp and DksA mediated control of σ54-dependent transcription

    Author : Lisandro Bernardo; Victoria Shingler; Victor de Lorenzo; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ppGpp; DksA; σ54-transcription; global regulation; E. coli; P. putida; Molecular biology; Molekylärbiologi;

    Abstract : The σ54-dependent Po promoter drives transcription of an operon that encodes a suite of enzymes for (methyl)phenols catabolism. Transcription from Po is controlled by the sensor-activator DmpR that binds (methyl)phenol effectors to take up its active form. READ MORE

  5. 18. A study of the rail degradation process to predict rail breaks

    Author : Saurabh Kumar; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Rail infrastructure is a large and costly investment, and has a long life. To realize the benefits from this investment, effective maintenance is required. READ MORE

  6. 19. Life and Death of Mixed Metal Halide Perovskites : Mechanism and Consequences of Light Induced Halide Segregation in MAPb(I,Br)3

    Author : Klara Suchan; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phase segregation; X-ray diffraction; perovskite; solar cells; photoluminescence;

    Abstract : Metal halide perovskites have attracted immense scientific interest due to their outstanding optoelectronic properties over a widebandgap range. Applications cover a wide range of optoelectronic devices from solar cells, LEDs and lasers to X-ray detectors. READ MORE

  7. 20. Legg-Calvé-Perthes Disease – Is it just the hip? : Epidemiological, Clinical and Psychosocial Studies with special focus on Etiology

    Author : Yasmin D. Hailer; Olof Nilsson; Sharham Bahmanyar; Fritz Hefti; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Legg-Calvé-Perthes disease; hypertension; ischemic heart disease; coagulation; risk factors; etiology; injury; quality of life; EQ-5D; IPAQ; physical activity; ADHD; ASRS; depression; mortality; Orthopaedics; Ortopedi;

    Abstract : The overall aim of the thesis was to add some pieces to the etiological puzzle of LCPD with special focus on vascular origin and hyperactivity. Furthermore we wanted to evaluate some consequences of LCPD in adulthood.Swedish registry data were used to identify a cohort of patients with the diagnosis of LCPD. READ MORE
