11. Algorithms for Coherent Diffractive Imaging with X-ray Lasers
Abstract : Coherent diffractive imaging (CDI) has become a very popular technique over the past two decades. CDI is a "lensless" imaging method which replaces the objective lens of a conventional microscope by a computational image reconstruction procedure. READ MORE

12. The Structure of Chinese Timber Architecture Twelfth century design standards and construction principles
Abstract : This thesis examines the building standards and construction principles prescribed and used in the construction of state buildings of the Song Dynasty (960 - 1279), China, from the viewpoint of architectural design. It aims to answer three fundamental questions: (1) What measuring system was used in the carpentry design and construction? (2) What building scales and proportions were prescribed for and used in state buildings of the time? (3) What were the interrelations of the structural patterns and roof types, and what were their relationships to the building scales and proportions? The thesis begins by providing detailed explanations of the highly refined and unique Song period modular system which governed not only the sizes of each individual elements, but also the dimensions of structural grids and the proportion of entire building.

14. Nano-particulate Silica Hydrogels Imaged in 2D and 3D using TEM: Effects of local pore structure on mass transport and applications in aggregation dynamics
Abstract : 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.

15. 3D nano-tomography using coherent X-rays
Abstract : 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).
