11. Enhancing material and biological properties of calcium phosphate bone substitute
Sammanfattning : Calcium phosphate materials (CaPs) have proven biocompatible and useful in clinical situations. One CaP showing promise in the clinic is alpha phase tricalcium phosphate ([alpha]-TCP). [alpha]-TCP in powder form can be hydrated and undergoes a reaction resulting in calcium deficient hydroxyapatite (CDHA). LÄS MER
12. Free Volume Determination in Polymers and Polymer Blends
Sammanfattning : The free volume of a polymer, which corresponds to the unoccupied regions accessible to segmental motions, is an important parameter for understanding and predicting many of its characteristic properties. The concept of free volume is the basis for understanding the molecular mobility in polymers. LÄS MER
13. Multivariate Analysis of 2D-NMR Spectroscopy : Applications in wood science and metabolomics
Sammanfattning : Wood is our most important renewable resource. We need better quality and quantity both according to the wood itself and the processes that are using wood as a raw material. Hence, the understanding of the chemical composition of the wood is of high importance. LÄS MER
14. Engineering of Native Cellulose Structure for Pharmaceutical Applications : Influence of Cellulose Crystallinity Index, Surface Area and Pore Volume on Sorption Phenomena
Sammanfattning : Cellulose powders from various sources were manufactured and characterized to investigate the influence of their crystallinity index, surface area, and pore volume on sorption phenomena and the relevant pharmaceutical functionality. The influence of the cellulose crystallinity index on moisture sorption was important at low and intermediate relative humidities. LÄS MER
15. Melt spinning of poly(vinylidene fluoride) mono- and bicomponent fibres and yarns : the formation of piezoelectric beta-phase crystallinity
Sammanfattning : The present study investigates the possibilities of manufacturing piezoelectric polymer fibres or yarns for integration into textile materials. The polymers known to give the strongest piezoelectric effects are poly(vinylidene fluoride) (PVDF) and some of its copolymers. LÄS MER
