In this work, we report the room-temperature synthesis of pure calcium tungstate (CaWO4) and copper-doped calcium tungstate solid solution (Ca0.99Cu0.01WO4) by using a sonochemistry method. These materials were structurally characterized by X-ray diffraction (XRD) and Raman spectroscopy. The obtained XRD patterns were submitted to a Rietveld refinement showing, in both materials, a tetragonal phase with space group and point group of I41/a and C4h6, respectively. Microscopy images of both materials, ...

Abstract Among Neotropical freshwater ecoregions, the Mid-Northeastern Caatinga (MNCE) is a fish knowledge gap. Its temporary drainages are receptors of the São Francisco interbasin water transfer project (SFR-IWT) in the Brazilian semiarid. We provide a comprehensive baseline of fish richness of the five SFR-IWT basins. Species richness, shared, endemic, threatened and non-native species were obtained using sampling, ichthyologic collections, literature and online repositories (306 localities). In ...

Phosphorus is an essential element for all living organisms and important also for agricultural production. The content of P in most agricultural soils in Brazil is low. In order to supply the plant needs and the soil fixation, application of P fertilizer is required. Among the various options of P fertilizers in the market, the totally acidified phosphates are usually commercialized. The evaluation of the efficiency of the reactive natural phosphates as P fertilizers is important due to the increase ...

Drought is by far the most important environmental factor contributing to yield losses in crops, including soybeans [Glycine max (L.) Merr.]. To address this problem, a gene that encodes an osmotin-like protein isolated from Solanum nigrum var. americanum (SnOLP) driven by the UBQ3 promoter from Arabidopsis thaliana was transferred into the soybean genome by particle bombardment. Two independently transformed soybean lines expressing SnOLP were produced. Segregation analyses indicated single-locus ...

Corner-truncated cubic β-Ag1.94Cu0.06MoO4 microcrystals were synthesized using the hydrothermal method. These were investigated by X-ray diffraction, confirming obtention of the spinel structure Fd3̅m. Through Raman spectroscopy are confirmed all modes for the point group of Oh7. The Egap shows a decrease of the band gap from 3.20 to 3.07 eV, with reduction of the conduction band occurring from -0.20 eV (β-Ag2MoO4) to -0.13 eV (β-Ag1.94Cu0.06MoO4), suggesting a p-type behavior for the Cu2+ ion.

The plant materials included seven parents from the Solo and Formosa groups and three hybrids from the cross between these two groups. Some genotypes could be fingerprinted by the presence or absence alone of some bands, but in general the DNA fingerprint could only be obtained by a set of RAPD markers.
