We have investigated the surface effect of colloidally prepared CdSe nanocrystals (NCs) with the size range of 23-40 Å on their structural properties by changing the organic capping ligands. The TOPO/HDA-passivated NCs reveal a size-dependent behavi

Kaolinite content of 10 raw Florida clays examined in this study was determined to be in the range of 70 to 90 mass %. This kaolinite content is sufficiently high for production of a potentially reactive pozzolanic material. The majority of the clays

An iterative Rietveld–PONKCS (partial or no known crystal structure) technique has been developed for precise and accurate determination of the weight percentages of predominantly amorphous supplementary cementitious materials (SCMs) contained in P

Increasing incorporation of metakaolin (MK) into field concrete mixtures necessitates careful study of the portland cement/MK hydrating systems. While a number of studies have been conducted on MK blends with cement, the current knowledge on its effe

Sulfate resistance of Portland cement-slag mixtures was compared at 30, 50 and 70% cement replacement levels for slags with variable Al2O3 and MgO content and variable fineness in combination with moderate- and high-C3A cements. Sulfate resistance ge

The iterative Born approximation is derived for three-wave dynamical X-ray diffraction. Dependence of the three-wave diffraction profiles of the diffracted wave on the polarization state of a linearly polarized incident wave is theoretically and expe

Multiple diffraction techniques for quantitative phase determination of macromolecular crystals are briefly described and overviewed. The modified second-order iterative approximation [Chang, S. L.; Tang, M. T.: Acta Cryst. A44 (1988) 1065] is employ

The polarization suppression of the interfering components in X-ray multiple-wave interaction is observed for the first time by using a polarization analyzer with an arbitrary inclination of the diffraction plane with respect to that of the investiga

A quasi-universal function describing the intensity distribution of three-wave X-ray interaction in single crystals is derived for the first time from X-ray dynamical theory under the Bethe approximation for inversion-symmetry related reflections. Th
