  1. 1. Inkjet printed piezoelectric energy harvesters based on self-assembly of diphenylalanine peptide

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yujie Fu; [2023]
    Keywords : Inkjet printing; piezoelectric energy harvester; diphenylalanine peptide; self-assembly; Bläckstråleutskrift; piezoelektrisk energiskördare; difenylalaninpeptid; självmontering;

    Abstract : Diphenylalanine peptide (Phe-Phe or FF) is a very promising bio-material in the future wearable electronics application due to its self-assembly into nanotubes and nanoribbons with high shear piezoelectric coefficient which is comparable to traditional inorganic piezoelectric materials. In order to efficiently harvest piezoelectric response, alignment and unidirectional polarization of FF nanotubes are required. READ MORE

  3. 2. Kvalitetsförändringar i ’Elise’- äpplen efter öppning av ULO-lager

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Dag Pålsson; [2023]
    Keywords : Äpplen; lagring; shelf-life; kvalité; fasthet; sockerinnehåll; livsmedelsförluster;

    Abstract : För att kunna erbjuda konsumenter svenskproducerade äpplen över en stor del av året lagras frukten i sk ULO (ultra low oxygen) -lagring. Genom att temperatur, relativ fuktighet och atmosfär reglerass kan biologiska processer, såsom respiration och etylenproduktion, kontrolleras och sänkas vilket resulterar i att frukten håller längre och har bättre kvalité över en längre tid.

  4. 3. Operando detection of Li-plating by online gas analysis and acoustic emission monitoring

    University essay from Uppsala universitet/Strukturkemi

    Author : Inti Espinoza Ramos; [2023]
    Keywords : Li-ion batteries; graphite; solid electrolyte interphase; lithium plating; online gas analysis; operando acoustic emission monitoring;

    Abstract : Lithium ion batteries (LIBs) are widely used for storing and converting chemical energy into electrical energy. During battery operation, lithium ions move between electrode materials, enabling energy storage. However, aging mechanisms like lithium plating can negatively impact battery performance and lifetime. READ MORE

  5. 4. Crystallization, optimization, and crystal structure determination of ligands in complex with galectin-8N

    University essay from Lunds universitet/Kemiska institutionen

    Author : George Larsson; [2022]
    Keywords : Biochemistry; Structural Biochemistry; Galectin-8; Protein Crystallization; Chemistry;

    Abstract : This thesis focuses on the protein “galectin-8N” which is a lectin protein that takes part in several physiological functions such as inflammation, autophagy, cell migration, and more. The project has three objectives: to observe and increase the reproducibility of crystallization of two variants (wildtype and mutant) of the human protein galectin-8N and to analyze the binding site when three different novel ligands are each inserted.

  6. 5. Investigating Brønsted Acidic Deep Eutectic Solvents for Recycling of Lithium Cobalt Oxide

    University essay from Uppsala universitet/Strukturkemi

    Author : Mattias Lindgren; [2022]
    Keywords : Deep eutectic solvents; Recycling; Lithium-Ion Batteries; Cathode Materials; LCO;

    Abstract : Recently, the production of lithium-ion batteries (LIB) has grown rapidly, highlighting the need for efficient and environmentally friendly recycling of LIB waste. In this work, the usage of so-called deep eutectic solvents (DESs) for the leaching of the LIB cathode material lithium cobaltoxide is investigated. READ MORE
