Conventional Fourier analysis is one of the most commonly used methods for localization of missing atoms in crystal structures from powder diffraction data. A “perfect” Fourier map would require a complete set of structure factors up to a resolution of at least sin/ = 5.0 Å. In the case of powder diffraction, accessible information is limited, as compared to single crystal diffraction, mainl...

LiNi2/3Sb1/3O2 has been prepared by ion-exchange from NaNi2/3Sb1/3O2. Powder X-ray diffraction (XRD) and single crystal electron diffraction y transmission electron microscopy (TEM) of the material indicate that it is isostructural with -NaFeO2. Electrochemical test shows that the eversible capacity for Li intercalation and deintercalation drops rapidly with the number of times cycled. Both exp...

Here we report a magnetic composite nanocatalyst (MP@NiSiO/Pd) with a rattle type nanostructure. The nickel silicate shell encapsulated magnetic core (MP@NiSiO) rattle particles were synthesized by using a facile templating method and the Pd nanocrystals with different sizes can be directly immobilized onto the MP@NiSiO rattles without using any surfactant or capping reagents. X-Ray powder Diff...

A possible application of a metal powder composition made high-temperature nickel-based alloy with high heat strength (the material is analogous to Inconel 718) in selective laser melting (SLM, an additive manufacturing technology) was considered. Peculiarities formation the course have been researched, and mechanical properties were determined. The effect thermal treatment mode on characterist...
