With an emphasis on assessment of reproducibility and precision of results, the technique of Mossbauer spectroscopy is applied to three groups of materials with increasing structural complexity: simple mineral standards, multivalent and multisite ferruginous micas, and multisite silicate glasses. In order to study the underlying accuracy of Mossbauer measurements of minerals, two mineral standa...

Crystal engineering, the design of molecular solids, is the synthesis of functional solid-state structures from neutral or ionic building blocks, using intermolecular interactions in the design strategy. Hydrogen bonds, coordination bonds, and other less directed interactions define substructural patterns, referred to in the literature as supramolecular synthons and secondary building units. Cr...

Antiferroelectric (AFE) materials are of great interest owing to their scientific richness and utility in high-energy density capacitors. Here, the history AFEs is reviewed, characteristics antiferroelectricity phase transition an AFE material described. energetically close ferroelectric (FE) phases, thus both electric field strength applied stress (pressure) influence nature transition. With c...

Programming the reaction chemistry for superseding the formation of Sm2O3 in a competitive process of formation and dissolution, the crystal growth patterns are varied and two different nanostructures of Sm2O3 in 2D confinement regime are designed. Among these, the regular and self-assembled square platelets nanostructures exhibit paramagnetic behavior analogous to the bulk Sm2O3. But, the othe...
