  1. 6. Real- and Quasi-Atomic Layer Etching for Ultra-High Resolution Patterning

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Yoana Ilarionova; [2023]
    Keywords : Physics and Astronomy;

    Abstract : An attempt was made at developing atomic layer etching from a cyclic etching process in an ICP-RIE tool. During the process OES was used for contamination monitoring and estimation of the relative amount of Cl2 left in the chamber during the etch step of cyclic etching processes. READ MORE

  3. 7. Model-Observation Comparisons of O+ Concentrations in the Martian Ionosphere

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Chinmaya Nagar; [2023]
    Keywords : MAVEN; NGIMS; Martian; Ionosphere; Fehsenfeld; Tenewitz;

    Abstract : A few years ago, the charge-transfer reaction CO2+  +  O ⟶ O+ + CO2 was investigated experimentally for the first time since the study by Fehsenfeld et al., (1970). This new investigation was conducted by Tenewitz et al., (2018). READ MORE

  4. 8. Cytokine capture with beads in cytotoxicity assays in microwells

    University essay from KTH/Tillämpad fysik

    Author : Maxime Simon; [2023]
    Keywords : Microbead; Inteferon gamma; Natural Killer cells; microwell; binding-reaction model; Mikrokula; Interferon gamma; Naturliga Mördarceller; Mikrobrunn; modell för bindningsreaktion;

    Abstract : Cytokines are small, secreted proteins that are important for cell signalling in theimmune system. Interferon gamma (IFN-γ) is one of the most potent cytokines thatnatural killer (NK) cells of the innate immune system secrete with both antiviral,antibacterial, and antitumoral activity. READ MORE

  5. 9. The effect of material properties on PEM fuel cell catalysts on durable oxidation reduction activity

    University essay from KTH/Kemiteknik

    Author : Xiaoling Jiang; [2023]
    Keywords : PEM fuel cell; catalyst; ORR activity; particle size; degradation; PEM-bränslecell; katalysator; syrgasreduktionsaktivitet; partikelstorlek; åldring;

    Abstract : I detta examensarbete utforskas påverkan av partikelstorleken hos Pt-katalysatorer på kolbärare på syrereduktionen i polymerelektrolytmembran (PEM)-bränsleceller. Den elektrokemiskt aktiva ytarean, aktiviteten för syrereduktion och tillhörande degraderingshastigheter för de undersökta katalysatorerna beräknas och jämförs. READ MORE

  6. 10. The transition of reaction-to-fire behavior from biomass to corresponding biochar

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jacob Johansson; [2023]
    Keywords : biochar; biomass; heat release rate; reaction-to-fire;

    Abstract : As of now, the environmental issue is very topical and there is also an underutilization of different biological material where these can be used in ways that are typically not thought of. One way to increase the degree of utilization is to convert various biomasses such as natural rubber, olive pits, wood chips, and reed pellets into biochar. READ MORE
