1. 6. SUSTAINABLE LUBRICATION FOR FUTURE TRANSMISSIONS : Micropitting performance of Glycerol-based lubricants

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Zapata Tamayo Juan Guillermo; [2021]
   Nyckelord :micropitting; mild sliding wear; surface coating; diamond-like carbon DLC; glycerol-based lubrication; green lubricant; rolling contact fatigue; rolling-sliding;

   Sammanfattning : Achieving sustainable lubrication by using environmentally friendly formulated lubricants has became an essential component of the transition process from fossil-powered vehicles to electrified transportation. Mixtures, or aqueous solutions of molecules such as polyhydroxy alcohols, and glycols usually known as green lubricants make it possible to achieve low friction coefficients under different lubrication conditions, which constitutes a potential alternative to improve the tribological performance of moving parts in automotive systems, at the same time that the environmental requirements are satisfied.

3. 7. Declining abundance and shifting distribution for Antarctic krill, Euphausia superba, in the western Antarctic Peninsula

   Master-uppsats, Lunds universitet/Examensarbeten i biologi

   Författare :Kerstin Holmström; [2020]
   Nyckelord :Biology and Life Sciences;

   Sammanfattning : Antarctic krill, Euphausia superba, a polar ocean specialist, thrives in the Antarctic severe physical conditions. The krill life cycle consists of strategies that have enabled and supported the species’ dominance of the Antarctic Ocean. Sea Ice extent and duration creates condition that are crucial for survival of the Furcilia larvae. LÄS MER

4. 8. Characterization of graphene-based sensors for forensic applications : Evaluating suitability of CVD graphene-based resistive sensor for detection of amphetamine

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Ülle-Linda Talts; [2019]
   Nyckelord :Sensor systems; Chemical sensors; Nanosensors; Drug screening; Nanomaterials; Sensorsystem; Kemiska sensorer; Nanosensorer; Drug screening; Nanomaterial;

   Sammanfattning : Recent improvements in sensor technology and applications can be partly attributed to the advancements in microand nanoscale fabrication processes and discovery of novel materials. The emergence of reliable and inexpensive methods of production of monolayer materials, such as graphene, has revealed the advantageous electronic properties which when utilized in sensory elements can significantly enhance response to the input signal.

5. 9. Influence of microstructure on surface characteristics in cold-deformed stainless steel tubes

   Master-uppsats, Lunds universitet/Materialteknik

   Författare :Fredrik Ottenklev; [2019]
   Nyckelord :Cold deformation; surface roughness; strain; microstructure; austenitic stainless steel; grain rotation; Technology and Engineering;

   Sammanfattning : Cold deformation of metals is known to induce roughness on their free surface. In some of the processing equipment of Tetra Pak processing systems, tubes of austenitic stainless steel 316L are used. During the production of this processing equipment, such tubes are occasionally cold-deformed. LÄS MER

7. 10. Intercoat adhesion : How can intercoat adhesion be studied and what influences intercoat adhesion

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Amanda Kessler; [2018]
   Nyckelord :;

   Sammanfattning : Coatings cover most objects in our daily lives. They can have functional properties such as protecting the coated material or esthetic properties to decorate and provide pleasant appearance. Coatings have historically dried by evaporation of solvents, but now, UV curing coatings are on the uprising. LÄS MER
