   Abstract : This thesis deals with novel aspects of Nanomaterials,Nanoscience and Nanotechnology. On the materials side, novelmethods were developed for the fabrication of nano-sizedbuilding blocks, such as nanoparticles, nanorods and nanowireswith defined structures and high homogeneity. Nanoparticleswere consolidated to nanostructured materials. READ MORE

5. 3. Metal-assisted chemical etching for nanofabrication of hard X-ray zone plates

   Author : Rabia Akan; Ulrich Vogt; Muhammet Toprak; Carmen Vogt; Lucia Romano; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; metal-assisted chemical etching; zone plate; high-aspect ratio; silicon; nanostructures; Material and Nano Physics; Material- och nanofysik; Optik och fotonik; Optics and Photonics;

   Abstract : Hard X-ray scanning microscopes, or nanoprobes, make it possible to image samples and probe their chemical, elemental and structural properties at nanoscale resolution. This is enabled by the use of nanofocusing optics. Commonly used optics in nanoprobes for high resolution X-ray experiments are zone plates. READ MORE
