  1. 1. Formulation development, rheological characterization, and cosmetic evaluation of gel-creams

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

    Författare :Carl Pontén; [2024]
    Nyckelord :Rheology; Texture analysis; Viscometry; Semisolids; Design of Experiments; Critical Process Parameters; Critical Quality Atttibutes; Pharmaceutical Technology; Technology and Engineering;

    Sammanfattning : Oil in water (o/w) emulsions are thermodynamically unstable systems composed of small oil droplets dispersed in a continuous aqueous phase. This means that given enough time, the two phases will separate. Pharmaceutical emulsions are used as a method of administering the Active Pharmaceutical Ingredient (API) for topical applications.

  3. 2. Uranium nitride synthesis by gas/gas reaction of UF6 and NH3

    Master-uppsats, KTH/Fysik

    Författare :Serena Ambrosino; [2024]
    Nyckelord :Uranium nitride; synthesis; ammonolysis; uranium hexafluoride; uranium tetrafluoride; ammonia; X-ray diffraction; microscopy; Urannitrid; syntes; ammonolys; uranhexafluorid; urantetrafluorid; ammoniak; röntgendiffraktion; mikroskopi;

    Sammanfattning : This thesis project aims to develop an innovative technique for the production of high-purity uranium nitride (UN) through the ammonolysis of fluorides. The desired objective is to perform a controlled gas/gas reaction between uranium hexafluoride (UF6) and ammonia (NH3) at 800°C. LÄS MER

  4. 3. Screening pyrolysis bio-oil as binder for carbon anode in aluminium production

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Yazhe Wang; [2023]
    Nyckelord :Biomass; Bio-oil; Bio-pitch; Carbon Anode; Aluminum production; Biomassa; Bioolja; Biobeck; Kolanod; Aluminium Produktion;

    Sammanfattning : Den högkvalitativa stenkolstjäran, som används som anodbindemedel inom aluminiumindustrin, innebär utmaningar när det gäller att möta kraven på kolanod. Dess produktion är beroende av ohållbara fossila bränslen, vilket bidrar till ökade koldioxidutsläpp. LÄS MER

  5. 4. Possibilities of Reducing Internal Scrap Rates and Increase Scrap Recyclability of Dilute Copper Alloys from Vertical Upwards Continuous Cast (VUCC) Process

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Minna Olsson; [2023]
    Nyckelord :metallurgy; copper; alloy; continuous casting; materials chemistry; Technology and Engineering;

    Sammanfattning : Copper and copper alloys are important material systems for the electrification of society. The high workability of the materials makes them appropriate in numerous different applications which require highly conductive properties. LÄS MER

  7. 5. Extraction of Global Features for enhancing Machine Learning Performance

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

    Författare :Abyel Tesfay; [2023]
    Nyckelord :Machine Learning; Deep Learning; Feature Extraction; Global Features; Time-series data; Bioprocessing; Maskininlärning; Djupinlärning; Funktionsextraktion; Globala Funktioner; Tidsserie data; Biobearbetning;

    Sammanfattning : Data Science plays an essential role in many organizations and industries to become data-driven in their decision-making and workflow, as models can provide relevant input in areas such as social media, the stock market, and manufacturing industries. To train models of quality, data preparation methods such as feature extraction are used to extract relevant features. LÄS MER
