  1. 1. Cellulose Nanofibril-based Hybrid Materials : Eco-friendly design towards separation and packaging applications

    Författare :Luis Valencia; Aji Mathew; Olli Ikkala; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cellulose nanofibrils; hybrid materials; membranes; aerogels; separation; food packaging; Materials Chemistry; materialkemi;

    Sammanfattning : Nanocellulose has been lately considered as the “Holy-Grail” in the design of sustainable materials due to its bio-origin and an unprecedented combination of prominent features, including good mechanical properties, anisotropy and versatile surface chemistry. In addition, nanocellulose in the form of cellulose nanofibrils, can adopt variable structures and morphologies depending on the processing technique, such as aerogels, films and monoliths. LÄS MER

  3. 2. Mesoporous Materials for Fast Charging Electrochemical Energy Storage

    Sammanfattning : High performing electrochemical energy storage (EES) devices are needed to cope with the increasing energy requirements of modern society. Electrode materials must store lots of energy, charge/discharge fast and be environmentally friendly. LÄS MER

  4. 3. Novel framework materials : organically templated silicogermanates and hybrid fluorotitanates

    Författare :Liqiu Tang; Xiaodong Zou; Gunnar Svensson; Gies Hermann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; framework materials; silicogermanates; hybrid fluorotitananates; Chemistry; Kemi;

    Sammanfattning : Two types of novel framework materials, including six organically templated silicogermanates and five hybrid fluorotitanates, have been synthesized, and their structures have been determined by single crystal X-ray diffraction. Their structures and the interactions between the organic and inorganic species are discussed in some detail. LÄS MER

  5. 4. Polymer-Nanoparticle Hybrid Materials for Plasmonic Hydrogen Detection

    Författare :Iwan Darmadi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; hydrogen; nanofabrication; hybrid material; nanocomposite; polymer; alloy; sensor; nanoplasmonic; palladium;

    Sammanfattning : Plasmonic metal nanoparticles and polymer materials have independently undergone rapid development during the last two decades. More recently, it has been realized that combining these two systems in a hybrid or nanocomposite material comprised of plasmonically active metal nanoparticles dispersed in a polymer matrix leads to systems that exhibit fascinating properties, and some first attempts had been made to exploit them for optical spectroscopy, solar cells or even pure art.
