  1. 1. Test setup for LDMX HCal readout

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Joshua Greaves; [2020]
    Keywords : Dark matter; LDMX; dark photon; hadronic calorimeter; photomultiplier tube; Physics and Astronomy;

    Abstract : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.

  2. 2. Banning Plastic Straw by Straw: Why California needs a more harmonized approach to plastics management

    University essay from Lunds universitet/Internationella miljöinstitutet

    Author : Rachel Adell; [2020]
    Keywords : Social Sciences;

    Abstract : Over 150 local communities in California have implemented plastic product bans as a way to decrease stress on landfills, reduce non-recyclable materials, and manage litter. Plastic product bans such as plastic bags, polystyrene, or single-use plastics, are used to address both local (e.g. litter reduction or community aesthetics), and global (e. READ MORE

  3. 3. Enhancing the degradation rate of microplastics and organizing a study visit about sustainability

    University essay from KTH/Lärande

    Author : Marianne Al-Ghorabi; [2020]
    Keywords : Accommodation; assimilation; Fenton reaction; microplastics; polypropylene; polystyrene; proximal development zone; study visit; visible light photocatalysis; zinc oxide nanorods; Ackommodation; assimilation; den proximala utvecklingszonen; Fenton reaktion; fotokatalys med synligt ljus; mikroplast; polypropalen; polystyren; studiebesök; zinkoxid nanorör.;

    Abstract : Microplastics take hundreds to thousands of years to degrade in nature, and pose a threat to the environment. A photocatalytical degradation method have been developed to take advantage of solar light to degrade microplastics, however it takes several months to degrade microplastics with the process.

  4. 4. Impacts on recyclability and sustainability in hanger production by replacing polystyrene with the biocomposite DuraSense® Pure S40 Impact D

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Luisa Fernanda Santiesteban García; [2020]
    Keywords : Gabi Envision; LCA; wood fibers; moulding; biocomposite;

    Abstract : Biocomposites have gained increasing attention in recent years. The environmental impacts of common plastics have led researchers and industrials to develop alternatives to fully petro-sourced materials (Beigbeder et al., 2019). READ MORE
