  1. 1. Molnens påverkan på jordens strålningsbalans och klimatsystem

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Hans Jägfeldt; [2022]
    Nyckelord :moln; kondensation; aerosol; strålningsbalans; klimat; klimatsystem; kosmisk strålning; troposfären; Earth and Environmental Sciences;

    Sammanfattning : The role of clouds in the climate system has been studied and their impact on the Sun's impact on the Earth's energy balance. The Earth's albedo affects the energy balance by influencing how much of the Sun’s radiation is reflected or absorbed. Clouds affect the Earth's albedo and therefore play an important role in this balance. LÄS MER

  3. 2. X-ray Photoelectron Spectroscopy on Clusters: From Water Clusters to Metal & Metal-Oxide Nanoparticles

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Emmanouil Tzomos; [2021]
    Nyckelord :Nanoscience; Nanoparticles; Clusters; Synchrotron Radiation; Water Particles; Silver Particles; Silver Oxides; Ethylene Epoxidation; Radiotherapy; PES; XPS; Lund University; FlexPES; MAX IV; Physics and Astronomy;

    Sammanfattning : In the present work, two experimental setups aimed at the production of (1) water clusters and (2) metal-oxide nanoparticles were assembled and commissioned. The experiments on the cluster/nanoparticle beams were set up and performed at the FlexPES beamline of the MAX-IV synchrotron facility. LÄS MER

  4. 3. Optimization of solid-phase extraction (SPE) as sample preparation for oil samples in forensic investigations.

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Aamanda Chang; [2021]
    Nyckelord :Solid-phase extraction SPE ; heavy fuel oil HFO ; fingerprint; polycyclic aromatic hydrocarbons PAHs ; biomarkers.;

    Sammanfattning : Oil spills, especially in water have happened throughout the years. The consequences from this kind of incident have always been a threat to marine life and take a lot of money and time to clean up. LÄS MER

  5. 4. Building with pollution

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Zornitsa Hristova Kovacheva; [2021]
    Nyckelord :Arts and Architecture;

    Sammanfattning : Black carbon is an ever-growing global problem and one of the most important environmental issues of this generation. Black carbon, also known as soot, is a highly polluting substance and it is the second-largest polluter after carbon dioxide. LÄS MER

  7. 5. DEVELOPMENT OF RISK INFORMED METHODS FOR ESTIMATING RADIATION RELEASE FROM CABLE FIRES AT HIGH ENERGY PHYSICS FACILITIES

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Daniel Funk; [2020]
    Nyckelord :Fire Safety Engineering; CERN; Fire-induced Radiological release; particle accelerator; Fire Protection; Fire Risk Analysis; Technology and Engineering;

    Sammanfattning : CERN operates the Large Hadron Collider (LHC), the world’s largest and most powerful particle accelerator. The LHC was built to advance the state of knowledge in particle physics by increasing the energy of colliding particles to the TeV range. LÄS MER
