  4. 7. Thin metal films on weakly-interacting substrates : Nanoscale growth dynamics, stress generation, and morphology manipulation

    Author : Andreas Jamnig; Kostas Sarakinos; Gregory Abadias; Gregory Thompson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thin films; magnetron sputter-deposition; in situ and real-time characterization; early film growth stages; residual stress; manipulation of morphology; Couches minces; pulvérisation magnétron; caractérisation in situ en temps réel; premiers stades de croissance; contraintes résiduelles; manipulation de morphologie;

    Abstract : Vapor-based growth of thin metal films with controlled morphology on weakly-interacting substrates (WIS), including oxides and van der Waals materials, is essential for the fabrication of multifunctional metal contacts in a wide array of optoelectronic devices. Achieving this entails a great challenge, since weak film/substrate interactions yield a pronounced and uncontrolled 3D morphology. READ MORE

  5. 8. Biogas generation in landfills : equilibria, rates & yields

    Author : Mattias Åkesson; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; model; limitation; volatile fatty acids; kinetics; biogas; thermodynamics; methane; Landfill; test cell; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : Landfilling in "cells" has become more common in recent years. Different waste streams are guided to different cells, among which the biocell is a landfill designed for biogas production. In this thesis, the dependence of biogas generation on waste composition was investigated. READ MORE

  6. 9. In-situ Investigations of Lithium-Sulfur Batteries

    Author : Matthew Sadd; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : As the demand for high energy-density storage devices increases, we must look beyond the current state of the art technology, the lithium-ion battery. Lithium-ion battery technologies are approaching their theoretical limit in terms of capacity, and now that the demand for longer-range electric vehicles (EVs) and the implementation of grid storage is increasing, we need to provide technologies that can go beyond what is currently possible.

  7. 10. Quantitative laser diagnostics of gas-phase potassium species in biomass combustion and gasification

    Author : Emil Thorin; Florian Schmidt; Markus Broström; Zhongshan Li; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermochemical conversion; pyrolysis; phosphorus; single pellet; entrained-flow; in situ; spectroscopy; photofragmentation; imaging; numerical modelling; fysik; Physics;

    Abstract : Thermochemical energy conversion processes, such as combustion and gasification, are applied worldwide for generation of electricity, heat and synthesis of chemicals. Today, these processes are mostly run on non-renewable, fossil fuels and constitute a major source of carbon dioxide emissions. READ MORE
