  1. 1. Influence of pulsing on PVD TiAlN coating microstructure and mechanical properties : Master thesis project on the impact of deposition parameters on performance and properties of PVD titanium aluminum nitride.

    University essay from Karlstads universitet

    Author : Marcus Roseen; [2023]
    Keywords : ;

    Abstract : This thesis investigates the influence of pulsing on the mechanical properties of PVD TiAlN coatings. The thesis focuses on defects caused by droplets during the arc-evaporation technique by altering the duty time, which affects mechanical properties. READ MORE

  3. 2. GRAPHENE MODIFIED E-TEXTILE : AN INDUSTRY RELEVANT APPROACH OF DOPING AND VISUALISING A FULLY TEXTILE P-N JUNCTION DIODES

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Bilel Meskini; [2023]
    Keywords : E-textile; viscose; polyester; graphene; graphene oxide GO; reduced graphene oxide rGO; tannic acid; plasma treatment; electrochemical deposition; doping; semiconductor;

    Abstract : As a wonder material, graphene has been studied in various applications due to its exceptional properties. Recently it has been used in textile to obtain functionalised garments as E-textile. From an industry-relevant perspective, it is essential to introduce a process that could be scaled-up. READ MORE

  4. 3. Conceptualisation, Implementation and Commissioning of a Controlled Pyrolysis Rig : KTH Master Thesis Report

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Arjun Monga; [2023]
    Keywords : coke deposition; pyrolysis; catalysis; methane; sample; cooling channels; regenerative cooling; rocket engines; koksavsättning; pyrolys; katalys; metan; prov; kylkanaler; regenerativ kylning; raketmotorer;

    Abstract : Liquid methane has seen popular interest from industry and academia as a next-generation rocket fuel due to its favorable performance characteristics and potential for extra-terrestrial in-situ resource utilisation. Since the rocket combustion chamber and nozzle are subject to high heat loads, regenerative cooling is a standard method to achieve lower temperatures. READ MORE

  5. 4. Long-term Nitrogen Deposition and Recovery of Epiphytic Lichens : Concealed memory and implications

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Camille Volle; [2022]
    Keywords : epiphytic lichens; N deposition; boreal forest; recovery; critical load;

    Abstract : Anthropogenic activities have increased nitrogen (N) emissions. However, higher N deposition is associated with negative fallouts in ecosystems, highlighting the necessity to define its critical load (CLO). Lichens, with their lack of roots, stomata, and cuticles, are helpful air pollution indicators and can be used to establish N CLO. READ MORE

  6. 5. Synthesis and thermoelectric properties of Cr1-xMexN (Me = Mo, V)

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Victor Rutberg; [2022]
    Keywords : Chromium nitride; thin films; thermoelectrics; physical vapour deposition; medium entropy alloy;

    Abstract : Among emerging materials systems for thermoelectric applications, the early transition-metal nitrides based on ScN and CrN show unexpectedly promising properties. These properties are determined by high Seebeck coefficient, low thermal conductivity, and high electrical conductivity. READ MORE
