1. Nano-particulate Silica Hydrogels Imaged in 2D and 3D using TEM: Effects of local pore structure on mass transport and applications in aggregation dynamics
Sammanfattning : Porous materials are frequently used in everyday applications including food science, pharmaceuticals, fuel cell membranes, batteries and solar cells. A key aspect in these porous materials is how their micro- and nano-structure affect the internal transport of for example water, particles or charges. The transport is a three-dimensional process.

2. From Silica Nano-Particles to Silica Gels and Beyond - Salt Induced Aggregation of Silica Nano-Particles and the Stability of Resultant Gels
Sammanfattning : Aqueous silica nanoparticle suspensions are widely available and used within a number of industries. A relatively new area of application is as a grouting material for sealing narrow fractures in tunnels. LÄS MER
3. Atom Probe Tomography Investigations of Biologically Relevant Nanoparticles
Sammanfattning : The study of materials at the nanoscale is essential in many scientific disciplines. For example, in materials science the size of the building blocks of a material is directly linked to its properties. LÄS MER
4. Synthesis of zeolites from economic raw materials
Sammanfattning : Synthesis methods using economic raw materials, such as kaolin and diatomite have been developed for the production of zeolites in the present work. Zeolite Y and ZSM-5 have been synthetized successfully from diatomite and kaolin, respectively. LÄS MER
5. Characterization of supported lipid membranes towards the development of nano-sized drug carriers for hyperthermia applications
Sammanfattning : So called thermosensitive liposomal drug carriers for temperature-controlled drug release under hyperthermal conditions have recently attracted great attention and advanced lipid membrane - nanoparticle assemblies are emerging at an increasing rate to meet the demands for multifunctional drug carriers in medicine. The rational design of these drug delivery systems will require understanding of lipid membrane physicochemical properties under conditions relevant to the medical treatment. LÄS MER
