  1. 1. 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.

    Keywords : Philippines; Philippine Carabao Center; Sieve Machine; Smallholder farmer; Vermicompost; Filippinerna; maskkompostering; Philippine Carabao Center; siktmaskin; småskaliga bönder;

    Abstract : The Philippines has a primarily agricultural economy, with many rural residents relying on farming for their livelihoods. The Philippine Carabao Center (PCC) was established in 1992 to support smallholder farmers in the country through research and technology development related to carabaos. READ MORE

  6. 5. Life Cycle Assessment of Absolicon solar thermal collector field for district heating in Härnösand

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ohm Ariyakhajorn; [2023]
    Keywords : Life Cycle Assessment; Solar Thermal Energy; District Heating System; Livscykelanalys; Solvärme; Fjärrvärmesystem;

    Abstract : Global energy consumption has been increasing continuously every year. Many energy sources are utilized. Conventional fossil fuels are not sustainable, and their environmental impacts are more apparent than ever before. For heating purposes, most of the heat still comes from combustion of both non-renewable and renewable energy sources. READ MORE
