1. 16. Elucidating Chemical and Electrochemical Side-Reaction Mechanisms in Li-ion Batteries

   Författare :Neeha Gogoi; Erik Berg; M. Rosa Palacín; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion battery; solid electrolyte interphase; electrolyte additives; reaction mechanism; ethylene carbonate; vinylene carbonate; tris trimethylsilyl phosphate; surface enhanced Raman spectroscopy; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Sammanfattning : Lithium-ion batteries constitute a leading technology that plays a major role in the transition towards sustainable transportation and power generation. The stability of modern batteries relies on a passivation layer formed on the negative electrode known as the solid electrolyte interphase (SEI). LÄS MER

3. 17. Anti-Ageing Strategies : How to avoid failure in sodium-ion batteries

   Författare :Le Anh Ma; Reza Younesi; Daniel Brandell; Laurent Duda; Philipp Adelhelm; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sodium-ion batteries; manganese-based cathodes; solid electrolyte interphase; ageing mechanism; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

   Sammanfattning : In order to move away from fossil fuels, batteries are one of the most important technologies to store energy from renewable sources. The rapid demands of battery applications put pressure on supply chains of raw materials, such as lithium, nickel, copper, aluminium and cobalt. LÄS MER

4. 18. The Complex Nature of the Electrode/Electrolyte Interfaces in Li-ion Batteries : Towards Understanding the Role of Electrolytes and Additives Using Photoelectron Spectroscopy

   Författare :Katarzyna Ciosek Högström; Kristina Edström; Håkan Rensmo; Leif Nyholm; John Owen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Li-ion battery; LiFePO4 graphite cell; interface; electrolyte additives; solid electrolyte interphase SEI ; photoelectron spectroscopy PES ; synchrotron; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

   Sammanfattning : The stability of electrode/electrolyte interfaces in Li-ion batteries is crucial to the performance, lifetime and safety of the entire battery system. In this work, interface processes have been studied in LiFePO4/graphite Li-ion battery cells. LÄS MER

5. 19. Characterisation of chromosomal aberrations in childhood leukaemia

   Författare :Ann Nordgren; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Chromosome aberrations; SKY; interphase-FISH; Childhood ALL;

   Sammanfattning : Acute lymphoblastic leukaemia (ALL) is the most common malignancy in childhood, accounting for approximately 25% of all paediatric malignancies. Based on clinical risk criteria and modem laboratory investigations including immunophenotyping, cytogenetics, and molecular genetics, patients can be divided into prognostic groups and assigned to risk- adjusted treatment protocols.

7. 20. Mitotic failure and genome stability in benign, premalignant and malignant human tissues

   Författare :Rüdiger G Steinbeck; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :aneuploidy; CDF; clonal selection; DNA content; image microphotometry; interphase; microsection; nondisjunction; unbalanced telophase;

   Sammanfattning : Mitotic failure may occur throughout the human lifespan. Individual nuclear mistakes will escape detection within the mass of somatic cells. The probability of nondetection increases with progression in development. LÄS MER
