   Sammanfattning : Currently metal nanoparticles (NPs) are a subject of interest regarding many applications, in particular chemical gas sensing, as the associated environmental issues are of substantial importance. Metal NPs are attractive due to their fascinating optical properties and primarily, localized surface plasmon resonance (LSPR) which strongly depends on size and shape of NPs. LÄS MER

4. 33. Nanocellulose and Metal-Organic Framework-Based Composites : Synthesis, Characterization, and Applications

   Författare :Shengyang Zhou; Chao Xu; Maria Strömme; Lars Wågberg; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocellulose; Metal–organic frameworks; Nanocomposites; Interfacial synthesis; Porous materials; Energy storage; Water purification;

   Sammanfattning : Nanocellulose is one of the most promising of the green materials available for use in a sustainable economy because of its natural abundance and renewability. Compared to petroleum‒derived synthetic polymers, nanocellulose has many unparalleled advantages such as its unique nanofibrous structure, high thermal stability, mechanical flexibility, rich surface chemistry, biocompatibility, and biodegradability.
