Triply Ordered 6H Halide Perovskites: A Family of Triangular Lattice Antiferromagnets.
Inorg Chem
January 2025
Department of Chemistry and Biochemistry, The Ohio State University, Columbus, Ohio 43210, United States.
Three new hexagonal perovskites with CsMMRhCl (M = Na, Ag; M = Mn, Fe) stoichiometry have been synthesized from solution precipitation reactions. These air-stable compounds crystallize as triply cation-ordered variants of the 6H perovskite structure. This structure contains octahedra that share a common face to form MRhCl dimers that are arranged on a two-dimensional triangular network.

Background: Left ventricular assist device (LVAD) has been widely used as an alternative treatment for heart failure, however, aortic regurgitation is a common complication in patients with LVAD support. And the O-A angle (the angle between LVAD outflow graft and the aorta) is considered as a vital factor associated with the function of aortic valve. To date, the biomechanical effect of the O-A angle on the aortic valve remains largely unknown.

Current understanding of the histology of the dermoskeleton of tetrapods comes from fossilized and recent remains of skulls, osteoderms, carapace, plastron and other postcranial material which were always investigated using linear cross polarized light (LCPL) microscopy. The pectoral girdle of vast majority of non-amniote tetrapods, including temnospondyls evolved large ventrally located dermal bones- the interclavicle and a pair of clavicles. Despite that, there is a lack of information about the bone tissue structure from these postcranial dermal bones.

The ZSM-5 zeolite is the key active component in high-severity fluid catalytic cracking (FCC) catalysts and is routinely activated by phosphorus compounds in industrial production. To date, however, the detailed structure and function of the introduced phosphorus still remain ambiguous, which hampers the rational design of highly efficient catalysts. In this work, using advanced solid-state NMR techniques, we have quantitatively identified a total of seven types of P-containing complexes in P-modified ZSM-5 zeolite and clearly revealed their structure, location, and catalytic role.

Sorghum anthracnose is one of the major diseases that have negative impacts on sorghum production in Ethiopia. This study was conducted to evaluate the resistance response of sorghum genotypes against sorghum anthracnose and to determine yield performances of sorghum genotypes under field conditions in two consecutive cropping years. Forty-nine sorghum genotypes were tested for their reactions to anthracnose in the East and West Hararghe Zones, East Ethiopia, during the 2017 and 2018 main cropping seasons.
