1. In Light of Ionic Materials : A short exploration of ionic materials for light-related applications
Sammanfattning : Ionic liquids (ILs) have been one of the most attractive classes of materials of the last decades. The reason behind this is their peculiar set of properties, which enable their possible application in several research fields. ILs are salts that exhibit a very low melting point, which has been arbitrarily defined to be below 100 °C. LÄS MER
2. Electrochromic Nickel – Tungsten Oxides : Optical, Electrochemical and Structural Characterization of Sputter-deposited Thin Films in the Whole Composition Range
Sammanfattning : This thesis investigates the electrochromic NixW1-x oxide thin film system, where 0 < x < 1. The thin films were deposited by reactive DC magnetron co-sputtering from one Ni and one W metal target. In addition, Ni oxide was deposited with water vapor added to the sputtering gas. LÄS MER
3. Experimental study and simulation of sintering of 316L components produced by binder jetting
Sammanfattning : Binder Jetting (BJT) is a multi-step Additive Manufacturing (AM) technique that is used for producing components with highly complex geometries and competitive final properties with high productivity when compared to other AM technologies. The first step provides the basic part geometric shape (BJT printing), and the next step (debinding and sintering) consolidates the part to reach final geometry and intended basic material properties.

4. 3D printing of Green Water Purification Filters : Design towards Sustainable and Scalable Biocomposite Materials
Sammanfattning : The globally escalating water pollution and water scarcity necessitates the development of efficient and sustainable water treatment technologies. This thesis investigates the feasibility of utilizing renewable and waste materials in the form of green composites for the fabrication of water purification filters via Fused Deposition Modelling (FDM).

5. Electrocatalyst materials for low-temperature hydrogen fuel cells
Sammanfattning : Fuel cells have emerged as one alternative to satisfy the need of energy systems with net-zero emissions. Although fuel cells date back to the 1800s, it is only during the last decades that their research has boosted to ease their commercialization. LÄS MER
