  1. 1. Visualization, modeling and consequences of residual stresses in glass frit sealing of a UV light source

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Mikrosystemteknik

    Författare :Vilma Hurtigh Grabe; [2023]
    Nyckelord :bonding; micro system; glass frit; sealing; finite element; modeling; glass; mikrosystem; sammanfogning; glasfog; fog; finita element; modellering; glas;

    Sammanfattning : PureFize Technologies AB develops and manufactures a broadband ultraviolet (UVC) light technology device that is mercury-free and based on nanotechnology, using the principle of field emission. The light source is made of Ti and glass, which are hermetically bonded, using a low-temperature glass frit, at elevated temperatures. LÄS MER

  3. 2. 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

  4. 3. Lignin in Cosmetics: State of the Art : Discerning the value of lignin in the cosmetic industry

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Industriell teknik; Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Nellie Henriksson; Klas Nordell; [2023]
    Nyckelord :Lignin; Cosmetics; Personal care; Innovation; Cosmetic industry; Functional materials. Biotechnology; functional materials; green chemistry; Lignin; kosmetik; kosmetikaindustrin; Bioteknik; Nanomaterial; SPF; UV;

    Sammanfattning : This study was carried out at the Department of Nanotechnology and Functional Materials,Uppsala University, one of several places where the interest of lignin in cosmetics is constantly growing. The functionalities of lignin have been studied to a great extent revealing its potential as a natural biopolymer to serve as a replacement for environmentally hazardous components in cosmetic formulations, namely UV-filters in sunscreens.

  5. 4. Poor risk management or external factors, what caused the semiconductor shortage within the automotive industry?

    Kandidat-uppsats, Göteborgs universitet/Företagsekonomiska institutionen

    Författare :Ebba Rimsäter; Simon Reinbro; [2022-04-07]
    Nyckelord :Risk management; Semiconductor shortage; Different risks; Buffer; Just-in-time; Supply chain management; Enterprise Risk Management and Traditional Risk Management;

    Sammanfattning : The purpose of this study is to investigate if and how risk management within the automotive industry has contributed to the outcome of semiconductor shortage, which has been affecting the industry since the beginning of 2020. The thesis is conducted as a qualitative interview study where data is gathered through interviews with people of interest, such as experts in the field of risk management, professors in nanotechnology and persons who work at automotive companies that have been directly affected by the semiconductor crisis.

    Sammanfattning : Derek Parfit är kanske en av vår tids mest kända moralfilosofer. Parfit inleder sin första bok Reasons and Persons med att ställa frågan: vad har vi mest skäl att göra? Hans fråga berör vad som egentligen har betydelse, en fråga som han fortsätter att beröra i sin andra bok On What Matters. LÄS MER
