11. Fabrication of nanocellulose-based materials : Liquid crystalline phase formation and design of inorganic–nanocellulose hybrids
Sammanfattning : The increasing need to replace fossil fuels as a source of energy and raw material is resulting in extensive research efforts towards identifying and developing high performance materials and devices based on renewable sources. Cellulose being the most versatile and abundant biopolymer in nature is one of the obvious choices. LÄS MER
12. 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
13. Interaction of water with supplementary cementitious materials: Hydration mechanism, microstructure and moisture transport
Sammanfattning : Supplementary cementitious materials (SCMs) offer a sustainable solution to reduce carbon emissions from the production of cement and concrete. This dissertation explores the impact of SCMs and the related additives on the hydration process of cementitious materials, which can affect their microstructure and transport properties. LÄS MER
14. Extracellular Matrix Based Materials for Tissue Engineering
Sammanfattning : The extracellular matrix is (ECM) is a network of large, structural proteins and polysaccharides, important for cellular behavior, tissue development and maintenance. Present thesis describes work exploring ECM as scaffolds for tissue engineering by manipulating cells cultured in vitro or by influencing ECM expression in vivo. LÄS MER
15. Formation of mesostructured silica based on non-ionic interactions
Sammanfattning : Mesostructured silica is a material consisting of a silica matrix with an organization in the meso range of 2-50 nm. The silica matrix is most often amorphous while the organization, induced by a structure directing agent, may generate a long-range mesoorder. LÄS MER
