  1. 1. Development of a Method to Predict the Adhesion of Industrial Paint Coating

    University essay from KTH/Fiber- och polymerteknologi

    Author : Akheen Sadik; [2022]
    Keywords : Contact angle technique; optical tensiometer; paint coating; adhesion promoter; silane; kontaktvinkel; optisk tensiometer; ytbehandling; adhesion; silan;

    Abstract : I samarbete med Sherwin-Williams AB, utvecklades en metod med kontaktvinkelmätning för att teoretiskt uppskatta vätbarhet och vidhäftningsförmåga av industriella färger på stålsubstrat. Optisk tensiometer och Youngs ekvation kombinerat med OWRK beräkningsmodell användes för att bestämma ytenergier. READ MORE

  3. 2. Silicon surface passivation via ultra-thin SiO2, TiO2, and Al2O3 layers

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Anton Ek; [2019]
    Keywords : surface passivation; ALD; silicon; solar cell; SiO2; Al2O3; TiO2; stacks; characterization; optimization; RSM; temperature;

    Abstract : Energy traps at the silicon surface originating from discontinuities in the lattice is detrimental to the performance of solar cells. Acting as recombination centers, they offer a location where the charge carriers may easily return to their original energy band after excitation. READ MORE

  4. 3. Optical Properties of Silicon Nanopillar Arrays for Biosensing

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Inese Krasovska; [2014]
    Keywords : ;

    Abstract : Biosensing is currently a growing research field which is relevant for different applications, for instance in health care. Sensitive and cheap biosensors are required, preferably as simple as possible in their working principle. READ MORE

  5. 4. PROCESSUTVECKLING FÖR JÄRNBASERADE HÅRDMAGNETISKA PULVER UTAN SÄLLSYNTA JORDARTSMETALLER

    University essay from Lunds universitet/Materialteknik

    Author : Per-Olof Andersson; [2014]
    Keywords : Crystalline metals; Magnetic materials; Hard magnetic materials; Electro-magnetic applications; Single crystalline powder; Powder metallurgy; Fe2B; FeB; Water atomization; Gas Water atomization; non-RE hard magnetic material.; Technology and Engineering;

    Abstract : An experimental study was performed, aimed at finding a way to produce single crystalline powder of pure (Fe0.7Co0.3)2B with a particle size of 100-200nm. This was done with the ultimate goal of producing a hard magnetic ferrite powder for powder metallurgical production of permanent magnets. READ MORE

  6. 5. A process recipe for bonding a silicone membrane to a plastic substrate

    University essay from Institutionen för teknikvetenskaper
