1. 1. Multi-functional Chromophores

   Författare :Fredrik Johansson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : As the push towards green energy become stronger, more efficient systems needs to be developed to compete with fossil fuel based systems. In modern Grätzel solar cells, most of the energy losses are inherited from the choice of chromophore and metal oxide surface. LÄS MER

5. 4. Development of Constituents for Multi-functional Composites Reinforced with Cellulosic Fibers

   Författare :Zainab Al-Maqdasi; Roberts Joffe; Nazanin Emami; Liva Pupure; Yvonne Aitomäki; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose fibers; multi-functional; composites; nano-reinforcement; thermoplastics; development; Polymeric Composite Materials; Polymera kompositmaterial;

   Sammanfattning : Bio-basedcomposites are being increasingly used in applications where weight saving,and environmental friendliness is as important as structural performance. Obviously, bio-based materials have their limitations regarding durability and stability of the properties,but their potential in use for advanced applications can be expanded if they were functionalized and considered beyond their structural performance.
