1. Water diffusion and free volume in hydrophilic polymers
Sammanfattning : During moisture uptake in polymers, the diffusion of the water molecules is believed to occur via unoccupied voids. These voids are called free volume cavities and their sizes are continuously altered when the moisture content in the polymer is enhanced. LÄS MER
2. Lithium-intercalated Carbon Fibres : Towards the Realisation of Multifunctional Composite Energy Storage Materials
Sammanfattning : Lightweight design is a major improvement path for sustainable transport asit contributes to lower vehicles energy consumption and gas emissions. Anovel solution to weight savings is to store energy directly in the mechanicalstructure of the vehicle with a multifunctional material, called structural battery,which could simultaneously bear mechanical loads and store electricalenergy.

3. Lightweight multifunctional composites : An investigation into ion-inserted carbon fibres for structural energy storage, shape-morphing, energy harvesting & strain-sensing
Sammanfattning : The transport sector accounts for around 26% of all greenhouse gas emissions in the European Union and United Kingdom. By reducing the mass of vehicles it is possible to reduce these emissions substantially.One way to reduce vehicle mass is to use multifunctional structures. LÄS MER
4. Process and properties of continuous fibers based on cellulose nanocrystals and nanofibers
Sammanfattning : In recent years, composites made from natural fibers based on cellulose have received increasing attention since they have a low environmental impact and good mechanical properties. However, these fibers are short and discontinuous and the conventional spinning techniques used for these fibers results in continuous yarns with mechanical properties considerably lower than that of the single fibers.

5. Computational modelling of structural battery composites
Sammanfattning : Batteries and surrounding structures (e.g. battery modules and packs) in electrical vehicles and devices are often designed in a way that prevents the electro-chemically active part of the battery cells from being exposed to mechanical loads during operation/service. LÄS MER
