Structural Analysis of Molecular Materials Using the Pair Distribution Function

Maxwell W. Terban et al.

Summary: This article reviews the application of atomic pair distribution function (PDF) analysis in the study of molecular materials. The PDF method is a powerful tool for investigating short- and intermediate-range order in nanoscale materials. It can provide structural details that are obscured in reciprocal space by defects, disorder, or structural ambiguities. While its use in inorganic and nanomaterials research has been highlighted, significant progress has also been made in applying PDF analysis to molecular materials such as carbon, pharmaceuticals, polymers, liquids, coordination compounds, and composites. The article provides an overview of applications in a wide variety of molecular compounds and systems, and offers pedagogical descriptions and tips for implementation.

Bridging Structural Inhomogeneity to Functionality: Pair Distribution Function Methods for Functional Materials Development

He Zhu et al.

Summary: The correlation between structure and function is crucial in materials science and engineering. Modern functional materials often exhibit inhomogeneities at the atomic level, giving them unique properties related to electrons, phonons, and magnetic moments. The pair distribution function (PDF) technique has emerged as a powerful tool for detecting local structure away from average in functional materials, with the advancements in crystallographic techniques and the availability of synchrotron X-rays, spallation neutrons, and advanced computing power.

Synthesis and characterization of Gd2O3: Er3+, Yb3+ doped with Mg2+, Li+ ions-effect on the photoluminescence and biological applications

Izabela Kaminska et al.

Summary: Nanoparticles with efficient upconverting luminescence were synthesized, with a notable increase in red luminescence intensity for 2.5% Mg2+ doping. X-ray analysis showed that the largest crystallite size at 2.5% Mg concentration contributed to the enhancement of luminescence intensity, while the addition of Li+ ions decreased the crystallite size.

Correlating Local Structure and Sodium Storage in Hard Carbon Anodes: Insights from Pair Distribution Function Analysis and Solid-State NMR

Joshua M. Stratford et al.

Summary: Hard carbons are the primary candidate anode materials for sodium-ion batteries, with the sodium-insertion mechanisms and local atomic environments still being debated. Research findings indicate that the local structure of carbons is described by bilayers of curved graphene fragments, with fragment size and curvature correlated with storage capacity. Different hard carbons show variations in performance at high and low voltages, suggesting that the impact of local atomic structure and microstructure on storage capacity should be considered when engineering these materials.

Structural insights on Li+ doped P6 crystals of upconverting NaYF4:Yb3+/M3+ (M3+ = Er3+ or Tm3+) through extensive synchrotron radiation-based X-ray probing

Preeti Verma et al.

Summary: This paper investigates the influence of non-lanthanide dopant insertion on the structural attributes of UC crystals through synchrotron-based X-ray probing, revealing that Li+ doping leads to variations in crystal structures without predictable effects on UCL intensity behavior. The study highlights the existence of local lattice disorder reflected in lattice strain, which correlates with changes in UCL intensity regardless of activator ions, indicating a perturbation of local symmetry field connected with local disorder not always manifested through average structural attributes like lattice parameters.
