1. 1. SFEER Hydrogen Permeation : Finding a suitable coating for the PA6 liner

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Elsa Friis; Klara Karlsson; Rebecka Damgren; Emma Åkesson; Malin Johansson; [2023]
   Keywords : Hydrogen permeation; PA6; coating; hydrogen permeation barrier; polymer hydrogen permeation; permeation; protective coating; hydrogen embrittlement;

   Abstract : Water Stuff & Sun are developing a hydrogen battery based on a technology called SFEER’s. The SFEER’s are spherical high-pressure gas storage containers that are the size of a tennis ball. They consist of a carbon fiber-shell that is lined on the inside with a polymer called PA6.

3. 2. Design and Development of a Data Acquisition and Communication System for Point Absorber Tracking

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Balakrishnan Kannan; [2021]
   Keywords : Data Acquisition System; Raspberry Pi; Controller; Processor; Wave buoy; Lysekil; wave energy; measurements; IMU; GPS; Strain gauge; force; Solar energy; Battery; communication; 4G; internet; Remote tracking; Shell; Python;

   Abstract : The recent trend in generating energy from the waves has led to several advancements in the methods and the various research is conducted across the world, to study the behaviour of point absorbers on the waves. The point absorbers such as wave buoys are designed to move according to the waves and the generator that is mechanically coupled with the buoys, generate electricity. READ MORE

4. 3. Development of magnetic lignin nanoparticles from low-molecular-weight eucalyptus and spruce lignin fractions

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Anna Wessén; Eliot Diklev; Lejla Al-Tamimi; [2020]
   Keywords : Magnetic nanoparticles; Hardwood; Softwood; Self-assembly; Lignin;

   Abstract : Lignin is one of the most common biopolymers in the world. Together with cellulose andhemicellulose it constitutes the fibers in the wood. It has a high molecular weight due to its complexstructure consisting of crossed-linked phenolic monomers and is concatenated with different types ofcarbon and ether bonds. READ MORE

5. 4. Ultra-light weight design through additive manufacturing

   University essay from Mälardalens högskola/Akademin för innovation, design och teknik

   Author : Barrett Sauter; [2019]
   Keywords : additive manufacturing; AM; fused deposition modeling; FDM; polymer; buckling; post-processing treatments;

   Abstract : ABB Corporate Research was looking to redevelop one product to be manufactured via polymer additive manufacturing (AM), as opposed to its previously traditionally manufacturing method. The current product is cylindrical in shape and must withstand a certain amount of hydrostatic pressure. READ MORE

6. 5. Investigation of Bismuth Iodine as Light Absorbing Materials for Solar Cell Applications: From Synthesis to XPS Characterisation

   University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

   Author : Jonatan Fast; [2017]
   Keywords : Bismuth; Iodine; Light absorbing; Light absorbing materials; Solar; solar cell; Synthesis; XPS; Characterisation; synchrotron; energy; x-ray photoelectron spectroscopy; perovskite;

   Abstract : During the last years perovskite materials have taken the photovoltaic community by storm, bringing promises of solar cells with efficiencies comparable to conventional silicon devices but at a lower price. However perovskite solar cells so far are facing two main obstacles, they are unstable in the presence of air, moisture and heat and they are usually toxic due to being based on lead-halide materials.
