Both ferroelectric and switchable dielectric behaviors are of great academic value and practical significance, but they usually exist alone. If combine the two properties into one compound, it will be more valuable in practical application.

The manipulation of structures and properties is a useful method in designing new materials. In this paper, two organic–inorganic hybrid compounds [(C6H15ClNO)2CoX4] (1, X = Cl; 2, X = Br) with reversible phase transition characteristics have been successfully synthesized. Systematic characterizations including crystal structure, thermal, dielectric, semiconducting, and photoluminescence properties were performed. Replacement of Cl with Br brings about not only the variation of the space group from C2/c to P21/c but also their properties. In comparison with Cl, the large Br atom could slow down the phase transition dynamics and give a larger thermal hysteresis of ∼25 K. Consequently, different shapes of switchable dielectric transition behavior are shown between 1 and 2. In addition, compound 2 has a smaller semiconducting band gap Eg than 1 (1.60 vs 1.65 eV). The results of this study will provide positive clues to manipulate the property of organic–inorganic hybrid compounds.

Solid-state UV/Vis diffuse reflectance spectroscopy shows that there is a wide optical band gap of 3.42 and 3.44 eV for 1 and 2. Photoluminescence measurement of solid-state samples revealed that 1 and 2 exhibit red or green emission, respectively.

Energy transfer mechanism is explained by the energy level diagram of the Eu3+ and Tb3+ ions and of the isonicotinic acid ligand. The complexes have CIE chromaticity coordinates of (0.59, 0.35) and (0.29, 0.48) for 1 and 2, respectively.

Organic–inorganic hybrid metal halides with temperature-triggered responsive switchable dielectric properties have evoked great attention for their potential application in the field of optoelectronic information.

The (H2TCPP)2+ cation displays a distorted saddle motif. A three-dimensional (3D) supramolecular framework is formed via hydrogen-bonding interactions. The compound shows a red photoluminescence emission.

Lung cancer is one of the most malignant cancers around the world, with high morbidity and mortality. Metastasis is the leading cause of lung cancer deaths and treatment failure. MicroRNAs (miRNAs) and long non-coding RNAs (lncRNAs), two groups of small non-coding RNAs (nc-RNAs), are confirmed to be lung cancer oncogenes or suppressors. Transforming growth factor-β (TGF-β) critically regulates lung cancer metastasis. In this review, we summarize the dual roles of miRNAs and lncRNAs in TGF-β signaling-regulated lung cancer epithelial-mesenchymal transition (EMT), invasion, migration, stemness, and metastasis. In addition, lncRNAs, competing endogenous RNAs (ceRNAs), and circular RNAs (circRNAs) can act as miRNA sponges to suppress miRNAs, thereby mediating TGF-β signaling-regulated lung cancer invasion, migration, and metastasis. Through this review, we hope to cast light on the regulatory mechanisms of miRNAs and lncRNAs in TGF-β signaling-regulated lung cancer metastasis and provide new insights for lung cancer treatment.

Two novel lanthanide-mercury compounds [Ln(IA)3(H2O)2]n(Hg3Cl9)n·4nH2O (Ln = Eu (1) and Tb (2); IA = isonicotinic acid) have been synthesized under solvothermal conditions and structurally characterized by single-crystal X-ray diffraction.

Wheat kernel morphology is a very important trait for wheat yield improvement. This is the first report of association analysis of kernel morphology traits in wheat breeding lines. In Qinghai, China, the research described here involved genome-wide association analysis in breeding lines derived from synthetic hexaploid wheat with a mixed linear model to identify the quantitative trait loci (QTLs) related to kernel morphology. The 8033 effective Diversity Array Technology (DArT) markers produced a genetic map of 5901.84 cM with an average density of 1.36 markers/cM. Population structure analysis classified 507 breeding lines into three groups by Bayesian structure analysis using unlinked markers. Linkage disequilibrium decay was observed with a map coverage of 2.78 cM. Marker-trait association analysis showed that 15 DArT markers for kernel morphology were detected, located on nine chromosomes, and explained 2.6%–4.0% of the phenotypic variation of kernel area (KA), kernel width (KW), kernel length (KL) and thousand-kernel weight (TKW). The marker 1139297 was related to both the KL and KA traits. Only six DArT markers were close to known QTLs. The parent SHW-L1 carried eight favored alleles, while other seven favored alleles were derived from elite common wheat cultivars. These QTLs, identified in elite breeding lines, should help us understand the kernel morphology trait better, and to provide germ-plasm for breeding new wheat cultivars for Qinghai Province or other regions.

The porphyrin macrocycles adopt a saddle-distorted nonplanar conformation with an embedded cobalt ion binding to four pyrrole nitrogen atoms. As revealed by the photoluminescence measurement, they exhibit blue emission. Variable-temperature magnetic susceptibility reveals that complexes 1–3 are antiferromagnetic. Their FTIR, CV, DPV, and UV/vis results are also studied in detail.
