1. 26. Development of corrosion resistant coatings using natural biopolymer and pollen

   University essay from KTH/Materialvetenskap

   Author : Alessandro Armani; [2020]
   Keywords : ;

   Abstract : Corrosion is a mechanism that highly reduces the lifetime of metals in different environments, especially in water or moisture environment. The worldwide maintenance cost due to corrosion is estimated in billions of dollars per year, and actual solutions in terms of coating usually contains toxic or environmentally harmful species.

3. 27. Theoretical and Experimental Characterizationof a Soft Polymer Heat Exchanger forWastewater Heat Recovery

   University essay from KTH/Energiteknik

   Author : Sixiang Lyu; [2020]
   Keywords : polymer heat exchanger; wastewater; heat recovery; heat transfer enhancement; oscillation i; polymervärmeväxlare; avloppsvatten; värmeåtervinning; förbättring av värmeöverföring; svängning;

   Abstract : Wastewater released from showers, sinks, and washers contains a considerable amount of wasteheat that can be recovered by using a heat exchanger. Conventional metal heat exchangers for wastewater heat recovery have common problems of corrosion, fouling and clogging, which makes it necessary to develop a new type of heat exchanger for such low-grade thermalenergy recovery applications.

4. 28. Sustainable corrosion protection for metallic materials by Mussel adhesive protein modified lignin film

   University essay from KTH/Materialvetenskap

   Author : Di Wang; [2020]
   Keywords : ;

   Abstract : Lignin has the potential to be used as green material to inhibit the corrosion of metallic substrates. Mussel adhesive protein is used to modify lignin due to its great adhesive and film forming abilities. READ MORE

5. 29. Safety Assessment of Cracked Buttress Dams

   University essay from KTH/Betongbyggnad

   Author : Robel Tekeste Fekadu; Sujata Kayastha; [2020]
   Keywords : Concrete buttress dam; finite element analysis; safety factor; global failure; reinforcement; corrosion; combined failure; traditional stability analysis;

   Abstract : Most of the concrete buttress dams in Sweden were built from the 1950s till the1980s based on the traditional method of analyses. Those structures are reinforced and heavy in structure. Their height to thickness ratio being large makes them prone to crack during their lifespan. READ MORE

6. 30. Spectroscopic evaluation of stability and homogeneity of formulated lubricant

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

   Author : Amir Vranjkovina; [2019]
   Keywords : Lubricants; Base oil; ICP-AES; FTIR; Method validation; Smörjmedel; Basoljor; ICP-AES; FTIR; Metodvalidering;

   Abstract : Lubricant is a common name for a large group of products that are essential for almost every engine or other machinery equipment that include mechanical part movements. Their main application is reduction of the friction between two rubbing surfaces by interposing a lubricating film between them. READ MORE
