  1. 1. Multifunctional ice and snow repellent coatings for photovoltaic modules

    University essay from Uppsala universitet/Solcellsteknik

    Author : Gunnar Sandkvist; [2023]
    Keywords : sol-gel; superhydrophobic; dip-coating; anti-reflective; silica;

    Abstract : Implementation of solar power by photovoltaic modules in cold climates, such as northern Sweden, implies several challenges. Ice and snow coverage not only leads to reduction in energy production due to shading, but it also puts equipment at risk from additional weight. READ MORE

  3. 2. A new generation ofsmart food packaging : A combination of releasing anti-microbial and generation carbon dioxide inmeat packaging

    University essay from Karlstads universitet

    Author : samar salahieh; [2023]
    Keywords : adsorption isotherms; desorption kinetics; benzoic acid; thymol; modified calcium carbonate; silica gel; carbon dioxide; food pad.; adsorptionsisotermer; desorptionskinetiken; bensoesyra; tymol; modifierat kalciumkarbonat; kisel gel; koldioxid; food pad.;

    Abstract : Abstract Food sustainability depends significantly on packaging since it helps maintainfood safe and fresh throughout its shelf life, resulting in the least amount ofwaste and the least negative environmental impact. The main objective of thisstudy is to determine the adsorbed and released amount of antimicrobial agents(benzoic acid and thymol) on modified calcium carbonate (MCC) by investigating adsorption isotherm at 25°C and desorption kinetics at both 22°C and5°C of anti-microbial to identify potential solutions to enhance the long-termsustainability of fresh products such as meat.

  4. 3. Synthetic gel particle formation for acoustofluidic applications

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Thibaut Valery; [2022]
    Keywords : agarose gel particles; acoustofluidics; droplet generation; microfluidic chip; Technology and Engineering;

    Abstract : Cancer cell detection by particle sorting systems is a very challenging field which could help to discover cancers at an earlier stage. Acoustophoresis used as a particle sorting system is based on the difference between the acoustic properties of particles and the medium. READ MORE

  5. 4. Optimization of solid-phase extraction (SPE) as sample preparation for oil samples in forensic investigations.

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Aamanda Chang; [2021]
    Keywords : Solid-phase extraction SPE ; heavy fuel oil HFO ; fingerprint; polycyclic aromatic hydrocarbons PAHs ; biomarkers.;

    Abstract : Oil spills, especially in water have happened throughout the years. The consequences from this kind of incident have always been a threat to marine life and take a lot of money and time to clean up. READ MORE

  6. 5. Easy-to-clean properties in coatings for automotive applications

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Weyni Ghebreamlak; [2021]
    Keywords : Easy-to-clean surface; sol-gel; superhydrophobicity; superoleophobicity; nanoparticles; Lätt-att-rengöra yta ”Easy-to-clean” ; sol-gel; superhydrofobicitet; superoleofobicitet; nanopartiklar;

    Abstract : En ”lätt-att-rengöra” yta definieras som en yta som stöter bort vatten och smuts. I detta projekt har klarlack med olika sammansättningar studerats i syfte att introducera egenskapen ”lätt-att-rengöra”. För att uppnå denna egenskap måste beläggningen vara superhydrofob och oleofob. READ MORE
