  1. 1. An Investigation of How Hydrophobicity, Water, and Surface Topography Influence Macroscopic Particle Accumulation on Surfaces : A Case Study of Grass Accumulation on Robotic Lawn Mower

    University essay from Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Author : Rasmus Brask-Nilsen; Petter Ydrestrand; [2023]
    Keywords : Macroscopic Particles; Accumulation; Hydrophobicity; Humidity; Topology; Adhesion; Experiments; Design of Experiments; Grass; Robotic Lawn Mower;

    Abstract : This master's thesis project investigates the impact of hydrophobicity and topology on dry and wet macroscopic particle accumulation on surfaces. The report begins by outlining the challenges associated with this phenomenon and the existing theories and methods used to study it, including adhesion, surface engineering, the Lotus effect, and humidity.

  3. 2. Quantum signatures in the work fluctuation-dissipation relation protocol

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Author : Jian Li; [2023]
    Keywords : Quantum entanglement; fluctuation; coherence; quantum information; quantum thermodynamics; Physics and Astronomy;

    Abstract : Quantum thermodynamics deals with the behavior of thermal machines that operate in the quantum regime, where coherences and entanglement can have a significant impact. However, detecting such quantum effects in thermal machines can be challenging, as they are primarily manifested as fluctuations. READ MORE

  4. 3. Statistics of Electric and Magnetic Fields at the Earth’s Bow Shock

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tsz-Kiu Wong-Chan; [2023]
    Keywords : MMS; Earth’s bow shock; Collisionless shocks; Correlation study; statistics; Space; Space plasma physics; MMS; Jordens bogchock; Kollisionsfria chocker; Korrelationsstudie; Statistik; Rymd; Rymdplasmafysik;

    Abstract : The interaction between the solar wind and Earth’s magnetic field creates the Earth’s bow shock. It is an ideal region for space probes like MMS, THEMIS or Clusters to study the collisionless shock phenomenon in space plasma. READ MORE

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

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