1. 21. First-Principles Investigation of Bulk and Interfacial Properties of Cu-Co Binary System

   Författare :Changle Li; Levente Vitos; Hongbin Zhang; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Teknisk materialvetenskap; Materials Science and Engineering;

   Sammanfattning : Due to the complex nature of phase interfaces, acquiring precise interfacial energies is usually a big challenge for both experimental measurements and computational modelings. In this thesis, we put forward an efficient route for assessing the temperature dependence of the interfacial energy using density functional theory (DFT). LÄS MER

3. 22. Stretchable electronics using wood-based functional materials

   Författare :Mohsen Mohammadi; Klas Tybrandt; Magnus Berggren; Martin Kaltenbrunner; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stretchable electronics; Wood-based functional materials; Cellulose nanofibrils; Lignosulfonate; Sustainable electronics;

   Sammanfattning : Stretchable electronics allows for direct integration into deforming systems like clothing, skin, and tissue, thereby enabling novel applications in soft robotics, wearable electronics, health monitoring, therapeutics, and human-machine interfaces. However, achieving seamless integration with the human body poses significant challenges, necessitating the development of functional materials with a low Young’s modulus matching biological tissues to avoid any discomfort or immune response.

5. 24. Functional hybrid and composite porous membranes derived from imidazolium-type poly(ionic liquid)

   Författare :Atefeh Khorsand Kheirabad; Jiayin Yuan; Naser Tavajohi Hassan Kiadeh; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; poly ionic liquid ; porous polyelectrolyte membranes; composite materials; functional membranes; materialkemi; Materials Chemistry;

   Sammanfattning : Poly(ionic liquid)s (PIL)s, as a subclass of polyelectrolytes, are composed of polymeric backbones with ionic liquid (IL)-based species in each repeating unit. Recent studies have deepened the understanding of the PIL concept in terms of characteristics, functions and applications in comparison to classical ILs and traditional polyelectrolytes. LÄS MER
