  1. 21. Molecular Insights into the Interactions of Monovalent Cations with Highly charged Fatty Acid Monolayers

    University essay from KTH/Kemi

    Author : Ran Carlhamn Rasmussen; [2023]
    Keywords : VSFS; Langmuir monolayer; ion specific effects; modified Poisson Boltzmann; carboxylic acid; VSFS; Langmuir monolager; jonspecifika effekter; modifierad Poisson Boltzmann; karboxylsyra;

    Abstract : Vibrational sum frequency spectroscopy har använts för att studera interaktionerna mellan monovalenta joner och laddade fettsyramonolager. Subfasen bestod av utvalda alkalihydroxidsaltlösningar med pH12, med huvudfokus på cesiumjonen. READ MORE

  3. 22. Flexural strength of dental restoratives

    University essay from Umeå universitet/Institutionen för odontologi

    Author : Mikael Blennow; Ahmed Al-Ahmed; [2023]
    Keywords : Flexural strength; porosity;

    Abstract : Background: New dental restorative material, “Cention Forte” and “Admira Fusion” have been available on the market for quite some time but are still new in comparison with traditional resin-based composite, “Ceram.x Spectra ST” and glass ionomer cement, “GC Fuji II LC”. READ MORE

  4. 23. Investigating self-discharge in a graphite dual-ion cell using in-situ Raman spectroscopy.

    University essay from Uppsala universitet/Strukturkemi

    Author : Ismail Yussuf Hassan; [2023]
    Keywords : graphite; dual-ion battery; parasitic reaction; cathode-electrolyte interface; anion intercalation; concentrated electrolyte; self-discharge; Raman spectroscopy;

    Abstract : Anion intercalation in the graphite positive electrode of a dual-ion battery requires high potential (> 4.3 V vs Li+/Li), which aggravates parasitic reactions involving electrolyte decomposition and Al corrosion, manifesting in poor coulombic efficiency, cycle life, and quick self-discharge.

  5. 24. A Machine Learning Approach on Analysis of Emission Spectra for Application in XFEL Experiments

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Harald Agelii; [2023]
    Keywords : Structural biology; Machine learning; Neural networks; emission spectrum; XFEL; X-ray free electron laser; SFX; Serial femtosecond X-ray crystallography; Proteins; Diagnostics;

    Abstract : In this thesis we investigate two potential applications of machine learning in the context of X-ray imaging and spectroscopy of biological samples, particularly such using X-ray free electron lasers (XFEL). We first investigate the possibility of using an emission spectrum, recorded from a sample after being probed by an incident X-ray, as a diagnostic tool. READ MORE

  6. 25. Combustibility study of resin for warm magnet coils used at CERN

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Juan Carlos Lopez Santiago; [2023]
    Keywords : Epoxy resin; flammability; radiation; aging; cone calorimeter; micro combustion calorimeter; thermogravimetric analysis; lateral ignition and flame spread test; chemical composition of polymers; polymers; epoxy composite; polymer composite; failure of epoxy resins; magnetic coil; Technology and Engineering;

    Abstract : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. READ MORE
