  1. 1. Effects of Immiscible Compressor Oil in a Flooded PSHE Evaporator : A Visual Study Approach

    University essay from KTH/Energiteknik

    Author : Joel Blomfelt; [2022]
    Keywords : ;

    Abstract : This paper deals with heat transfer in plate evaporators, with a focus on the effects caused by carried-over compressor oil ending up in the heat exchanger. A common standpoint in literature regarding the effect of immiscible oil contamination, in for example an ammonia PHE evaporator, is that the oil can accumulate as a layer on the plate surface causing an additional thermal conduction resistance.

  3. 2. 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

  4. 3. Formulation of nanoemulsions stabilized by cellulose nanocrystals

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

    Author : Marco Maccagno; [2020]
    Keywords : nanocellulose; hydroxypropyl methilcellulose; Pickering emulsions; microfluidization; drug delivery; nanocellulosa; hydroxipropylmetylcellulosa; Pickering emulsioner; microfluidization; drogleverans;

    Abstract : Cellulose nanocrystals (CNCs) are bio-based nanoparticles with the ability to stabilize oil and water emulsions thanks to their intermediate wettability and nanometric size. These and other types of particle-stabilized emulsions, commonly referred to as Pickering emulsions, are of great academic and industrial interest due to their superior stability against drop coalescence compared to classical surfactant-stabilized emulsions.

  5. 4. Inkjet deposition of electrolyte : Towards Fully Printed Light-emitting Electrochemical Cells

    University essay from Umeå universitet/Institutionen för fysik

    Author : Mattias Lindh; [2013]
    Keywords : inkjet printing; organic electronics; light-emitting electrochemical cell; solid electrolyte; coffee ring; stone ship; wettability; bläckstråleskrivare; organisk elektronik; ljusemitterande elektrokemiska celler; fast elektrolyt; kaffering; skeppssättning; vätbarhet;

    Abstract : Organic electronics is a hot and modern topic which holds great promise for present and future applications. One such application is the light-emitting electrochemical cell (LEC). It can be fully solution processed and driven at low voltage providing light emission from a large surface. READ MORE
