1. Towards Affordable Sodium-Ion Batteries : Mechanochemical Synthesis and Electrochemical Assessment of Iron-Based Fluorophosphate Cathode Material
Master-uppsats, KTH/MaterialvetenskapSammanfattning : An urgent transformation from fossil fuels to cleaner energy sources to combat climate change has led to the utilization of renewable energies like solar, wind, and tidal power. However, the intermittency of these sources hinders their wider implementation. To address this, large-scale electrical energy storage (EES) systems are needed. LÄS MER
2. Polymeric single Li+-ion conductors: preparation and characterisation
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : Lithium-ion batteries are a common type of light-weight, rechargeable batteries. There are safety concerns because these batteries typically use an organic solvent electrolyte which presents fire hazards. By using dry polymer electrolytes, the fire hazards can be eliminated.

3. Fabrication and evaluation of nickel containing nanofibres for solid oxide fuel cell anodes using electrospinning technique
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : The energy demand of the world continues to increase, while world's resources are exploited over its capacity. One way of facing these demands is to extend the use of fuel cells. A fuel cell converts chemical energy into electrical energy through a series of chemical and electrochemical reactions. LÄS MER
4. Patterning of Highly Conductive Conjugated Polymers for Actuator Fabrication
Master-uppsats, Linköpings universitet/Biosensorer och bioelektronikSammanfattning : Trilayer polypyrrole microactuators that can operate in air have previously been developed. They consist of two outer layers ofthe electroactive polymer polypyrrole (PPy) and one inner layer of a porous poly(vinylidene flouride) (PVDF) membranecontaining a liquid electrolyte. LÄS MER
5. A microtechnology-based sensor system for deepwater analysis from a miniaturized submersible
Uppsats för yrkesexamina på avancerad nivå, Ångström Space Technology Centre (ÅSTC)Sammanfattning : The aim of this master thesis has been to design, and partly manufacture and evaluate, a highly miniaturized, on-chip conductivity-temperature-depth (CTD) sensor system for deepwater analysis also including electrodes for pH and chloride ion concentration measurements. The microtechnology-based sensor system will be a vital instrument onboard the Deeper Access, Deeper Understanding submersible, which will be small enough for deployment through bore holes into the subglacial lakes of Antarctica.
