1. 3D Reconstruction of Porous and Poorly Conductive Soft Materials using FIB-SEM Tomography
Sammanfattning : Focused ion beam combined with scanning electron microscope (FIB-SEM) is a powerful tool that can be utilised to reveal the internal microstructure of materials. It basically uses ions to make cross-sections with high precision and electrons to image the cross-section surface with high spatial resolution. LÄS MER
2. Diabetes in 3D : β-cell mass assessments in disease models & evaluation of SPECT based imaging
Sammanfattning : Diabetes is a rapidly growing disease with 415 million affected adults worldwide. The pancreatic endocrine cells, most importantly the insulin producing β-cells, play an important role in regulating blood glucose homeostasis. LÄS MER
3. Contributions to 3D Image Analysis using Discrete Methods and Fuzzy Techniques : With Focus on Images from Cryo-Electron Tomography
Sammanfattning : With the emergence of new imaging techniques, researchers are always eager to push the boundaries by examining objects either smaller or further away than what was previously possible. The development of image analysis techniques has greatly helped to introduce objectivity and coherence in measurements and decision making. LÄS MER
4. Quantitative 3D reconstruction of porous polymers using FIB-SEM tomography -correlating materials structures to properties of coatings for controlled drug release
Sammanfattning : Porous networks are found in a wide range of different advanced and technologically important materials and influence the materials properties. The networks are active components in for example batteries, food and pharmaceuticals. The interconnectivity of a network strongly influences the transport properties. LÄS MER
5. 3D nano-tomography using coherent X-rays
Sammanfattning : X-rays allow to non-destructively investigate biological, chemical or physical processes at the nano-scale. Their high penetration depth in matter allows to investigate samples even inside sample environments, which would be difficult with complementary methods such as transmission electron microscopy (TEM).
