Article Synopsis
- The substitution of Ru by Ta in SrYbRuO leads to changes in its magnetic properties, showing stronger antiferromagnetic interactions in pure SrYbRuO compared to its Ta-substituted variants.
- As the concentration of Ta increases, the band gap of the material increases nearly linearly, indicating shifts in electronic structure and orbital ordering.
- The photoelectrocatalytic studies reveal that SrYbRuO has the highest photocurrent density and optimal performance for oxygen evolution reactions, with structural insights gained from techniques like XPS and EPR confirming the oxidation states and the presence of oxygen vacancies.
The single crystals of a quaternary sulfide, BaFeAgS, have been synthesized by reacting elements at 873 K inside a sealed fused silica tube. The title phase is the first ordered quaternary compound of the Ba-Ag-Fe-S system. The crystal structure of BaFeAgS is characterized by a single-crystal X-ray diffraction study at 298(2) K.

- GdFeO nanoparticles were created using a straightforward method involving citric acid, resulting in a highly crystalline orthorhombic structure as confirmed by X-ray diffraction and FTIR analysis.!* -
- Electron microscopy revealed worm-shaped nanoparticles with an average size of 95 nm and a distinct interplanar spacing of 0.12 nm on the (112) crystalline plane.!* -
- Notably, these nanoparticles exhibited room-temperature ferroelectricity and high dielectric properties, making them promising candidates for use in multistate memory devices.!*
Three new isostructural quaternary tellurides, BaLnMnTe (Ln = Pr, Gd, and Yb), have been synthesized by the molten-flux method at 1273 K. The single-crystal X-ray diffraction studies at 298(2) K showed that BaLnMnTe crystallize in the space group -C2/m of the monoclinic crystal system. There are six unique crystallographic sites in this structure's asymmetric unit: one Ba site, one Ln site, one Mn site, and three Te sites.

G-quadruplex-specific ligands that stabilize the G-quadruplex have great potential to be developed as anticancer agents. Two crystal structures (an apo form of parallel stranded human telomeric G-quadruplex and its holo form in complex with BRACO19, a potent G-quadruplex ligand) have been solved, yet the binding mechanism and pathway remain elusive.
