1. Wood-derived lignin-based fibers as supercapacitor electrodes
Abstract : Today, in order to replace fossil energy sources with renewable energy sources such as solar and wind, reliable energy storage systems that can provide power regardless of the intermittent nature of the energy sources must be created. Especially with the future’s rising energy demands the development of such energy storage systems from green-collar materials with the least negative environmental impact is pressing. READ MORE

2. Functionalized Porous Carbon Fiber Electrodes for Applications in Electrochemical Flow Cells
Abstract : Corrosion of metals in close-loop cooling or heating systems originates from tiny leakages at joints releasing oxygen into the thermal fluids. The presence of dissolved oxygen (DO) in thermal fluids, such as water with various additives forms a rust coating and some rust particles are released in the fluids and accumulate in an undesired place.

3. Carbon nanomaterial-based interconnects, integrated capacitors and supercapacitors
Abstract : The constant miniaturization and steady performance improvement of electronics devices have generated innovative ideas such as internet of thing (IoT), which also includes devices with integrated energy sources. The high performance is conceived by the high density of the devices on a chip leading to a high density of interconnects, to connect these devices to outside world. READ MORE

4. Conjoined piezoelectric harvesters and carbon supercapacitors for powering intelligent wireless sensors
Abstract : To achieve total freedom of location for intelligent wireless sensors (IWS), these need to be autonomous. To achive this today there is a need of broadband piezoelectric energy harvesting and a long-lasting energy. The Harvester need to be able to provide sufficient amount of energy for the intelligent wireless sensor to perform its task. READ MORE

5. Properties and applications of materials based on graphite oxide
Abstract : Graphite oxide (GO) is a hydrophilic, layered material prepared by oxidation of graphite. In the first part of this thesis, we studied materials produced from GO by intercalation and functionalization. The second part of the thesis was focused on supercapacitor applications of high surface area carbons prepared from GO using chemical activation. READ MORE
