... attempts in this study to synthesize chloro-amphiboles without A cations, such as chloro-ferro-hornblende [ Ca 2 ( Fe 4 2 + Al ) ( Al Si 7 ) O 22 Cl 2 ] and chloro-ferro-actinolite ( Ca 2 Fe 5 2 + Si 8 O 22...

... are unknown. Even the putative natural hydroxylapatite end-member from Holly Springs, Georgia, U.S.A., has been shown to contain both F and Cl in the anion column, obviating direct comparisons to human dental apatite ( Dykes and Elliott 1971 ). For this reason, Hughes et al. ( 2018 ) attempted to synthesize...

... to synthesize magnetite and gold/magnetite nanoparticles. The authors found that a high concentration of monomers (i.e., Fe 2+ , Au 3+ ) can promote the generation of small particles through homogeneous crystallization, which compete for monomers with the added magnetite seeds (i.e., heterogeneous...

...+ concentrations using a multi-anvil press. Using single-crystal X-ray diffraction (XRD) and Raman and FTIR vibrational spectroscopy, the hydrogen behavior in TiO 2 polymorphs was systematically investigated, providing new insight into hydrous SiO 2 polymorphs as isostructural analogs. To synthesize...

... homogeneous (PY3 = 17.3 ± 0.9‰, PY4 = 17.7 ± 0.8‰, PY5 = 17.9 ± 0.8‰, PY6 = 17.7 ± 0.6‰, ±2SD), and are consistent with IRMS δ 34 S values (17.8 ± 0.2‰ for PY3, 18.3 ± 0.9‰ for PY4, 18.2 ± 0.3‰ for PY5, 18.1 ± 0.1‰ for PY6, ±2SD). The homogeneity of 34 S/ 32 S suggests that CVT has the potential to synthesize...

... expensive computations to provide sufficient high‐resolution frequency. Nowadays, with the assistance of supercomputers, it is possible to synthesize broadband ground motions up to 10 Hz ( Rodgers et al. , 2020 ); however, such computational resources are not available for most engineering projects. (3...

... occurrence of natural hydrohematite with Fe occupancies near 0.85. Here, we provide a recipe to synthesize Fe-deficient hematite as a metastable product. Combining the natural discoveries of hydrohematite ( Chen et al. 2021 ) and our laboratory synthesis of hydrohematite, we interpret our results to indicate...

..., feiite is synthesized at lower pressures ( Fig. 5 ). This result suggests that the incorporation of Ti into the Fe 4 O 5 structure expands the stability of the mineral to lower pressures. We were not able to synthesize the end-member Fe 3 TiO 5 from a mixture of FeO and TiO 2 , indicating the pure Fe 3...

... to the variable compositions, fine crystallite sizes, difficulty to synthesize single crystals, and the widespread turbostratically disordered layers ( Ufer et al. 2004 ), XRD patterns of smectites contain no 3D information, and therefore, it is inapplicable to determine their crystal structures by traditional...
