Stabilization of δ-like BiO Phase at Room Temperature in Binary and Ternary Bismuthate Glass Systems with AlO, SiO, GeO, and BO.

Recently, it was shown that the nanocrystallization of Bi2O3 glasses with the addition of SiO2 and Al2O3 leads to the stabilization of the δ-like Bi2O3 phase at least down to room temperature, which is significantly below its stability range in bulk form. In this research, we investigated the properties of bismuthate glasses synthesized with various glass-forming agents such as SiO2, GeO2, B2O3, and Al2O3. It was demonstrated that vitrification of all these systems is possible using a standard melt quenching route.

Molecular characterization and functional analysis of the ecdysone receptor isoform (EcR) from the oriental fruit moth Grapholita molesta (Lepidoptera: Tortricidae).

20-Hydroxyecdysone (20E) plays a vital role in a series of biological processes, via the nuclear receptors, EcR/USP by activating the ecdysone regulatory cascade. To clarify the role of EcR during the development of Grapholita molesta, the complementary DNA of ecdysone receptor isoform B1 (GmEcR-B1) was obtained from the transcriptome of G. molesta and verified by PCR.

Improving sensitivity of XANES structural fit to the bridged metal-metal coordination.

Hard X-ray absorption spectroscopy is a valuable in situ probe for non-destructive diagnostics of metal sites. The low-energy interval of a spectrum (XANES) contains information about the metal oxidation state, ligand type, symmetry and distances in the first coordination shell but shows almost no dependency on the bridged metal-metal bond length. The higher-energy interval (EXAFS), on the contrary, is more sensitive to the coordination numbers and can decouple the contribution from distances in different coordination shells.

Temporal orientation of positive reappraisal.

Although it is well established that positive reappraisal-changing the way one thinks about an emotional event to feel more positive about it-is an effective emotion regulation strategy, researchers have only recently begun to characterize the relative utility and effectiveness of different forms of positive reappraisal. We propose that temporal orientation-thinking about the past versus the future-may be one particularly useful characterization of positive reappraisal. In three studies, participants were instructed to use positive reappraisal to feel better about a stressor and we either measured (Studies 1 and 3) or manipulated (Study 2) the orientation of those reappraisals to the future or to the past.
