1. Membrane evaluation and thermal modelling of the vanadium redox flow battery
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : In this study, different membranes were tested for their use in a vanadium redox flow battery (VRB). The membranes were first tested under charge-discharge operation of the VRB over four charge-discharge cycles at different current densities (20 mAcm-2, 40 mA cm-2 and 60 mAcm-2) and the corresponding cell performance was evaluated in terms of total energy efficiency (EE), coulombic efficiency (CE) and voltage efficiency (VE).

2. Vanadium Redox Flow Battery : Sizing of VRB in electrified heavy construction equipment
Master-uppsats, Mälardalens högskola/Framtidens energiSammanfattning : In an effort to reduce global emissions by electrifying vehicles and machines with internal combustion engines has led to the development of batteries that are more powerful and efficient than the common lead acid battery. One of the most popular batteries being used for such an installation is lithium ion, but due to its short effective usable lifetime, charging time, and costs has driven researcher to other technologies to replace it.

3. Flow batteries : Status and potential
Master-uppsats, Akademin för hållbar samhälls- och teknikutvecklingSammanfattning : New ideas and solutions are necessary to face challenges in the electricity industry. The application of electricity storage systems (ESS) can improve the quality and stability of the existing electricity network. LÄS MER
4. Kan man fastställa hållbarheten på en maträtt med hjälp av prognosmikrobiologi?
L2-uppsats, Lunds universitet/LivsmedelsteknikSammanfattning : Sammanfattning Cook-chill är en tillagningsmetod utvecklad för att tillgodose konsumenternas bekvämlighetskrav på färdigmaträtter. Cook-chill är tillagning av mat i stora kvantiteter med snabb efterföljande nedkylning. Nedkylningen ska snabbt till rekommenderad temperatur, från 90 °C till 3 °C inom 90 minuter. LÄS MER
