  1. 1. The O2 electrode performance in the Li-O2 battery

    Författare :Jia Liu; Jiefang Zhu; Kristina Edström; Poul Norby; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Li-oxygen battery; X-ray irradiation; Electrocatalyst; Synchrotron radiation powder X-ray diffraction; Time-resolved kinetics; Binder-free cathode; Bird’s nest microstructure.;

    Sammanfattning : Li-O2 batteries have been attracting increasing attention and R&D efforts as promising power sources for electric vehicles (EVs) due to their significantly higher theoretical energy densities compared to conventional Li-ion batteries. The research presented in this thesis covers the investigation of factors influencing the decomposition of Li2O2, the development of highly active electrocatalysts, and the design of low-cost and easy-operation binder-free O2 electrodes for Li-O2 batteries.

  2. 2. Raising the (roll)bar : exploring barriers and facilitators to research translation in US public health

    Författare :Pamela J. Tinc; Kristina Lindvall; Lars Weinehall; Julie Sorensen; Paul Jenkins; Per Nilsen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; implementation science; research to practice; scale-up; Consolidated Framework for Implementation Research; Proctor taxonomy of implementation outcomes; evidence-based practices; stakeholder engagement; rollover protective systems; tractor overturns; farm safety; occupational safety; injury prevention; Public health; folkhälsa;

    Sammanfattning : Background In public health, implementation science work is crucial to protecting the safety and health of populations. Despite this, such efforts have been extremely limited within the specific public health field of occupational safety and health. LÄS MER

  3. 3. Modeling the Lunar plasma wake

    Författare :Shahab Fatemi; Bengt Eliasson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rymdteknik; Space Technology;

    Sammanfattning : This thesis discusses the solar wind interaction with the Moon and the formation of the lunar plasma wake from a kinetic perspective. The Moon is essentially a non-conducting body which has a tenuous atmosphere and no global magnetic fields. The solar wind plasma impacts directly the lunar day-side and is absorbed by the lunar surface. LÄS MER

  4. 4. Kademlia on the Open Internet : How to Achieve Sub-Second Lookups in a Multimillion-Node DHT Overlay

    Författare :Raúl Jimenez; Seif Haridi; Björn Knutsson; Arnaud Legout; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dht; p2p; distributed systems; kademlia;

    Sammanfattning : Distributed hash tables (DHTs) have gained much attention from the research community in the last years. Formal analysis and evaluations on simulators and small-scale deployments have shown good scalability and performance. LÄS MER

  5. 5. Gut microbiota in colorectal cancer : The importance of Parvimonas micra

    Författare :Thyra Löwenmark; Richard Palmqvist; Sofia Edin; Pär Larsson; Michael Dahlberg; Per Hellström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; mucosal microbiota; Parvimonas micra; Fusobacterium nucleatum; immunity; survival; biomedical laboratory science; biomedicinsk laboratorievetenskap;

    Sammanfattning : Colorectal cancer (CRC) is a heterogenous disease consisting of multiple molecular subtypes, each of which has diverse treatment responses and prognoses. The importance of the gut microbiota in CRC development and progression has undergone increasing recognition in recent years, with a structural segregation in terms of microbial composition between CRC patients and healthy controls.
