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

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Yoana Ilarionova; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Sammanfattning : 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. LÄS MER

  4. 3. Developing an Ar milling process to improve the contact quality to InAs nanowires

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Författare :Chris Mkolongo; [2023]
    Nyckelord :InAs nanowires; Argon milling; Technology and Engineering;

    Sammanfattning : The aim of this work was to develop a stable and reproducible argon milling process for InAs nanowires to remove the native oxide layer that increases electrical resistance. This was done by identifying a few milling parameters and studying them in relation to the milling rate of silicon dioxide (SiO2). LÄS MER

  5. 4. The effect of lactose fines, magnesium stearate, choice of mixer and mixing process on the performance of adhesive mixtures for inhalation

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Gabriela Ponce Aparicio; [2023]
    Nyckelord :High shear mixing; low shear mixing; lactose fines; coating agent; budesonide; mixing energy; dry powder inhaler; carrier-based formulations; mixing time; adhesive mixtures; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : Dry powder inhaler (DPI) formulation is a major area of interest since they are employed by the healthcare system to treat relevant chronic diseases like asthma. Previous research has established that the manufacturing process and formulation composition are key for the active pharmaceutical ingredient to reach the lungs and achieve therapeutic effects.
