  1. 6. A Study on Lignin or Zein Based Hydrophobic Coatings

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Filippa Wentz; Sandra Olofsson; [2023]
    Keywords : Lignin; Zein; Hydrophobic Coating; Dispersion; Chemical engineering; Technology and Engineering;

    Abstract : The two by-products lignin, from the paper industry, and zein, from starch production, have shown potential as hydrophobic barriers. Therefore, this study has aimed to produce and in-vestigate the hydrophobicity of lignin or zein dispersions coated on paper. READ MORE

  3. 7. Developing an Environmentally Friendly Approach for Ash Removal in Hard Carbon Anodes

    University essay from KTH/Materialvetenskap

    Author : Diwen Wang; [2023]
    Keywords : Hard carbon; Acid wash; Biochar; Sodium-ion battery; Hårt kol; Syratvätt; Biokol; Natriumjonbatteri;

    Abstract : Hard carbon is regarded as one of the most promising anode materials for sodium-ion battery. However, the ash content of the hard carbon anode inherited from the precursor have several negative impacts on the electrochemical performance of hard carbon. READ MORE

  4. 8. The effect of temperature on the chemical stability of Vitamin C in a cosmetic product – Development of an HPLC-method for quantitative analysis

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Sofia Thuresson; [2022]
    Keywords : Vitamin C; HPLC; Stability; Degradation; Antioxidant; Vitamin C; HPLC; Stabilitet; Nedbrytning; Antioxidant;

    Abstract : Vitamin C är en populär ingrediens i hudvårdsprodukter, bland annat på grund av dess positiva effekter på kollagen-produktionen i huden och dess antioxidativa egenskaper. Dessvärre är vitamin C en känslig ingrediens som lätt bryts ned av ljus, syre, hög temperatur eller fel pH-värde. READ MORE

  5. 9. Life Cycle Assessment of a small scale, solar driven HVR water purification system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Sharang Kolathur; [2022]
    Keywords : life cycle assessment; air gap membrane distillation; solar energy; levelized cost; grid operated system; livscykelanalys; luftgapmembrandestillation; solenergi; utjämnade kostnader; nätdrivet system;

    Abstract : Water purification systems have made access to drinking water easier by treating water sources which previously could not be used for drinking. Such systems however require energy and materials to build and operate which means they have environmental impacts. READ MORE

  6. 10. Effekter av livsmedelsförädling för lokalkorrosion på rostfritt stål 316L

    University essay from Lunds universitet/Industriell Produktion

    Author : Fredrik Waldur; [2022]
    Keywords : Technology and Engineering;

    Abstract : Pitting corrosion on 316L stainless steel has been widely studied, but knowledge is lacking within food processing environments. A new test setup was developed to enable electrochemical measurements inside a heat exchanger (pasteurizer) where solutions can be heated and cooled rapidly, allowing for corrosion tests of solutions that do not withstand high temperatures for a long period of time.
