1. 3D Electron crystallography : Real space reconstruction and reciprocal space tomography
Abstract : Electron crystallography is an important technique for studying micro- and nano-sized materials. It has two important advantages over X-ray crystallography for structural studies: 1) crystals millions of times smaller than those needed for X-ray diffraction can be studied; 2) it is possible to; focus the electrons to form an image.

2. 3D Electron Microscopy Methods and Applications : Structures from Atomic Scale to Mesoscale
Abstract : The crystal structure determines the physical properties of a material. The structure can be analysed at different levels, from atomic level, mesoscale level, all the way up to the macroscale level. READ MORE

3. Contributions to 3D Image Analysis using Discrete Methods and Fuzzy Techniques : With Focus on Images from Cryo-Electron Tomography
Abstract : 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. READ MORE

4. Towards unbiased 3D reconstruction : in single-particle cryo-electron microscopy
Abstract : Cryo-electron microscopy of freestanding molecules (single-particles) plays a pivotal role in the difficult and pressing challenge of determining the structures of large macromolecular complexes. Molecular volumes are generated by aligning large sets of randomly oriented two-dimensional (2D) projection images in three dimensions (3D) before reconstruction is performed using tomographic techniques.

5. Visualising Functional Nanostructures of Organic Semiconductors using Electron Microscopy
Abstract : Organic semiconducting materials have enabled the solution-processable fabrication of light-weight and flexible electronic devices. In particular, doping using molecular dopants has enabled the fabrication of high-performance organic electronics. READ MORE
