    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanocellulose; nanofibril; nanofiber; CNF; nanoplatelet; nanostructure; tactoid; montmorillonite; MTM; foam; aerogel; porosity; PVA; poly vinyl alcohol ; epoxy; moisture; biocomposite; biomaterial; biobased; flame; cone calorimetry; gas barrier; coating; film.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Materials based on wood can offer sustainable alternatives to fossil-based plastics and composites, and show interesting mechanical properties. However, the issue of their flammability is generally unresolved. In this thesis, eco-friendly, fire retardant clay-cellulose nanofibril materials are investigated. READ MORE

  4. 2. On-chip electrochemical capacitors and piezoelectric energy harvesters for self-powering sensor nodes

    Author : Agin Vyas; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy storage; 2DOF; sensor node; Energy harvesting; piezoelectric energy harvesters; graphene oxide; spin coating; MEMS; Microsupercapacitors;

    Abstract : On-chip sensing and communications in the Internet of things platform have benefited from the miniaturization of faster and low power complementary-metal-oxide semiconductor (CMOS) microelectronics. Micro-electromechanical systems technology (MEMS) and development of novel nanomaterials have further improved the performance of sensors and transducers while also demonstrating reduction in size and power consumption.
