Accuracy limits of pair distribution function analysis in structural characterization of nanocrystalline powders by X-ray diffraction
Baloochiyan, Abolfazl; Batyrow, Merdan; Öztürk, Hande (Turkish Chemical Society, 2022)We report the minimum errors of structural parameters, namely lattice parameter, crystallite size, and atomic displacement parameters, expected from Pair Distribution Function (PDF) analysis of nanocrystalline gold powders ... -
Colloidal aluminum antimonide quantum dots
Jalali, H. B.; Sadeghi, S.; Şahin, M.; Öztürk, Hande; Ow-Yang, C. W.; Nizamoglu, S. (American Chemical Society, 2019-07-09)AlSb is a less studied member of the III–V semiconductor family, and herein, we report the colloidal synthesis of AlSb quantum dots (QDs) for the first time. Different sizes of colloidal AlSb QDs (5 to 9 nm) were produced ... -

Lower uncertainty bounds of diffraction-based nanoparticle sizes
Noyan, İ. C.; Öztürk, Hande (Wiley, 2022-06)A self-consistent analysis is reported of traditional diffraction-based particle size determination techniques applied to synthetic diffraction profiles generated with the Patterson approach. The results show that dimensions ... -
Microstructural examination of black seawater mixed sulfate-resistant cement concrete
Aydoǧan, O. G.; Akca, A. H.; Bilici, S.; Öztürk, Hande; Dilber, A. A.; Özyurt, N. (ASCE, 2024-01-01)The use of seawater as the mix water has been thought to be inevitable for the near future as a result of increasing water scarcity. Hundreds of papers related to seawater mixed cement-based materials were published in ... -
Resolving 500 nm axial separation by multi-slice X-ray ptychography
Huang, X.; Yan, H.; Ge, M.; Öztürk, Hande; Fang, Y.-L. L.; Ha, S.; Lin, M.; Lu, M.; Nazaretski, E.; Robinson, I. K.; Chu, Y. S. (International Union of Crystallography, 2019-03)Multi-slice X-ray ptychography offers an approach to achieve images with a nanometre-scale resolution from samples with thicknesses larger than the depth of field of the imaging system by modeling a thick sample as a set ... -
Size dependent change of mean square displacement in gold nanocrystals: A molecular dynamics simulation
Batyrow, Merdan; Fındıkçı, İlknur Eruçar; Öztürk, Hande (Wiley, 2023-11-01)Thermally activated atomic vibrations significantly decrease the x-ray diffraction intensities of nanocrystalline powders. Hence their quantification is critical for accurate structural characterization of small nanocrystals ...
