16. Tailoring of Transition Metal Silicides as Protective Thin Films on Austenitic Stainless Steel
Sammanfattning : The objective of this study is to make use of transition metal silicides in a novel way as protective thin films on engineering metals. It can then be possible to take advantage of the potentially good corrosion resistance of metal silicides while compensating for their brittle nature by the ductile bulk material. LÄS MER
17. Process development and Reliability Study for System-in-a-Package by using a Liquid Crystal Polymer Substrate
Sammanfattning : System-in-a-package (SiP) aims to integrate all of the system functions within a system-level package, containing multiple ICs and other components interconnected through a high-density substrate. SiP is characterized by dividing chip functions among several smaller chips, by connecting chips in the first stage of board manufacture, and by integrating passive components in the substrate.

18. Hydrometallurgical Treatment of Neodymium Magnet Waste
Sammanfattning : Recent decades have seen a considerable increase in the usage of rare-earth elements (REEs) in modern technologies and green energy sources. Recycling of REEs out of end-of-life products and E-scrap has become an alternative to mining them out of primary ores due to their supply risk in some countries and the development towards circular economies.

19. Nonstoichiometric Multicomponent Nitride Thin Films
Sammanfattning : High entropy ceramics have rapidly developed as a class of materials based on high entropy alloys; the latter being materials that contain five or more elements in near-equal proportions. Their unconventional compositions and chemical structures hold promise for achieving unprecedented combinations of mechanical, electrical and chemical properties. LÄS MER
20. Aqueous Organic Redox Flow Batteries - Electrochemical Studies of Quinonoid Compounds
Sammanfattning : Society faces a large challenge in transitioning to sustainably generating electricity from renewable energy sources such as wind and solar. One of the biggest obstacles to this transition is the intermittence of the sources, leading to a mismatch of supply and demand, a problem most commonly solved by installing large‐scale energy storage.
