1. 1. DRR in Colombia: The risk of reproducing rather than reducing disasters : A discourse analysis on the local sense-making of DRR in Huila, Colombia

   University essay from Försvarshögskolan

   Author : Daniel Magnil; [2024]
   Keywords : Disaster Risk Reduction; Vulnerability; Knowledge; Discourse Analysis;

   Abstract : The international community has been working on reducing disaster risks for decades, investing millions of dollars and implementing hundreds of projects in Disaster Risk Reduction (DRR). There is a broad consensus nowadays between academia and practitioners of how disasters result from exposure and vulnerabilities, where it’s essential to reduce these vulnerabilities. READ MORE

3. 2. Investigating self-discharge in a graphite dual-ion cell using in-situ Raman spectroscopy.

   University essay from Uppsala universitet/Strukturkemi

   Author : Ismail Yussuf Hassan; [2023]
   Keywords : graphite; dual-ion battery; parasitic reaction; cathode-electrolyte interface; anion intercalation; concentrated electrolyte; self-discharge; Raman spectroscopy;

   Abstract : Anion intercalation in the graphite positive electrode of a dual-ion battery requires high potential (> 4.3 V vs Li+/Li), which aggravates parasitic reactions involving electrolyte decomposition and Al corrosion, manifesting in poor coulombic efficiency, cycle life, and quick self-discharge.

4. 3. Real- and Quasi-Atomic Layer Etching for Ultra-High Resolution Patterning

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Yoana Ilarionova; [2023]
   Keywords : Physics and Astronomy;

   Abstract : An attempt was made at developing atomic layer etching from a cyclic etching process in an ICP-RIE tool. During the process OES was used for contamination monitoring and estimation of the relative amount of Cl2 left in the chamber during the etch step of cyclic etching processes. READ MORE

5. 4. Sustainable Recycling of Electrolytes for Vanadium Redox Flow Batteries : Method development and Review (Bachelor Thesis)

   University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Author : Reza Doulati; [2023]
   Keywords : vanadium redox flow batteries VRFB; eco-friendly recycling; precipitation of vanadium; vanadium oxides; Energy storage system; ESS; circular economy; sustainable recycling method;

   Abstract : Vanadium Redox Flow Batteries VRFBs are promising energy storage systems with highly recyclable electrolytes. The recycling of these systems usually involves ammonium-based salt precipitation steps, which produce toxicgases and contaminated water as waste. READ MORE

6. 5. The effects of fishing on stability of a food web under climate warming

   University essay from SLU/Dept. Of Aquatic Resources

   Author : Gabriel Nordström; [2023]
   Keywords : fishing; climate change; temperature; predator; consumer; resource; stage-specific; food webs; ontogenetic assymetry; biomass overcompensation; emergent Allee effects; limit cycles;

   Abstract : Predicting the effects of fishing in a warmer environment caused by climate change requires knowledge of what trophic level is fished on, the physiological effects of temperature on fish, and how these two affect ecological interactions. Both temperature and fishing are known to affect the stability of food webs in several ways. READ MORE
