1. 6. Puerto Rico Renewable Energy Oasis : Enhancing Disaster Relief and Recovery Efforts Through a Renewable Energy Microgrid in the University of Puerto Rico's Mayagüez Campus

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Arturo Garcia Palou; Jacob Mason; [2023]
   Keywords : ;

   Abstract : With the global rise in temperatures fueling an increase in Severe Weather Events (SWE) such as hurricanes, many islands around the world who lie in their path are seeking alternatives to their frequently outdated grid systems. These are often composed of dated infrastructure prone to damage during such events that leaves the dependent population without power for extended periods of time. READ MORE

3. 7. Hydrogen Absorption in Metal Hydrides : Transmission of light in relation to hydrogen concentration and site occupancy of ultrathin vanadium films

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : David Sörme; [2022]
   Keywords : metal hydrides; iron-vanadium superlattice; hydrogen; hydrogen site occupancy; hydrogen concentrationm; hydrogen storage;

   Abstract : In this study the effect of hydrogenation on the optical properties in the wavelength range 400-1023 nm of an ultrathin iron-vanadium superlattice is investigated. Specifically, mea- surements of transmission are performed under different states of hydrogenation, along with measurements of absolute hydrogen concentration and hydrogen site occupancy. READ MORE

4. 8. The Fe-oxides (mineralogical, chemical, and textural) variation in the Leveäniemi deposit using micro-analytical tools for unraveling of primary features and metamorphic recrystallisation

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Adrian Larsson; [2022]
   Keywords : Leveäniemi; Magnetite; Hematite; Iron oxides; Iron oxide apatite;

   Abstract : The Leveäniemi iron oxide apatite (IOA) deposit, mined by LKAB, is located in Norrbotten, northern Sweden. The deposit has a partially more complex mineralogy than the neighbouring and more famous IOA deposits of Kiirunavaara and Malmberget. READ MORE

5. 9. Accelerated Testing of the End-plate Assembly of a Redox Flow Battery

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Saksham Jindal; [2022]
   Keywords : Energy Storage; Flow Batteries; Accelerated Testing; Contact Resistance; Endplate Assembly; Leak Rate; Stack Design; Energilagring; flödesbatterier; accelererad provning; kontaktmotstånd; montering av ändplattor; läckagehastighet; utformning av staplar.;

   Abstract : As the world transitions to intermittent renewable energy sources like solar and wind, the need for long-duration energy storage technologies is becoming more and more prominent. In this regard, flow batteries are seen as a promising solution, owing to their inherent advantages like decoupling of power and energy, extremely high cycle life and negligible self-discharge.

6. 10. A study of optical and structural properties of spin-coated V2O3 thin films on sapphire substrates

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Jennifer Silander; [2022]
   Keywords : Optical properties; transmittance; FTIR spectrometry; scanning electron microscopy; x-ray diffraction; metal-insulator transition; crystalline material; sol-gel; spin-coating; vanadium oxide; infrared light;

   Abstract : Many transition metal oxides exhibit a Metal-Insulator Transition (MIT). This is an interesting phenomenon where the material undergoes a structural phase transition, and the electronic charge is redistributed in the crystal lattice. READ MORE
