  3. 2. Mitigation of supply chain uncertainties caused by material shortage : A case study with Loccioni

    Master-uppsats, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Författare :Juliane Wloch; [2023]
    Nyckelord :Supply chain risk management; supply disruption management; semiconductor shortage; Small- and Medium-sized Enterprises;

    Sammanfattning : The ongoing semiconductor shortage impacts organizations throughout the supply chain operationally and financially. Limited material for a sudden increase in demand during the Covid-19 pandemic led to a heightened supplier power and result in the prioritization of customers. LÄS MER

  4. 3. Assessing current state and potential direction of fossil-free hydrogen development in Sweden

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Sammanfattning : Plastic waste has brought a severe pollution problem that demands immediate attention. Promoted by policymakers, academia, and corporations alike, the circular economy model presents a viable path to sustainable development. Likewise, the emergence of disruptive technologies promises a profound and imminent socio-technical transformation. LÄS MER

  7. 5. Method development of an in vitro vertical Franz diffusion cell system to assess permeation of cosmetic active ingredients

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för kemi - Ångström

    Författare :Johanna Mattiasson; [2020]
    Nyckelord :chemistry; method development; Upsalite; Disruptive Materials; Franz; diffusion; penetration; permeation; skin; pharmaceuticals; cosmeceuticals; skincare; cosmetics; actives; mesoporous; material chemistry; kemi; kosmetika; Upsalite; Disruptive Materials; Franzcell; diffusion; läkemedel; metodutveckling; hud; penetration;

    Sammanfattning : For evaluation of potential skincare ingredients, an in-house method using Static Franz diffusion cells and dialysis membranes was developed. Benzoic acid was chosen as a model substance along with L-ascorbic acid and α-Tocopherol. The cell conditions were tailored to encourage transmembrane diffusion. LÄS MER
