Synergistic Adsorption-photocatalytic Activity using Z-Scheme Based Magnetic ZnFe2O4/CuWO4 Heterojunction for Tetracycline Removal
No full textDeveloping efficient and economical photocatalysts was considered as an efficient and economical strategy for pollution remediation. Herein, magnetically separable ZnFe2O4/CuWO4 composites (ZW) had been developed via combining ZnFe2O4 with CuWO4. The composite with a mass ratio of 40% CuWO4 (ZW-40) performed best, and the tetracycline hydrochloride (TC) removal by adsorption-photocatalysis of ZW-40 reached 86.5%. The photocatalytic degradation rated constant of it was 9.44 × 10−3 min−1, which was approximately 5.04 and 3.28 times compared to the ZnFe2O4 and CuWO4 samples, respectively. Pseudo-second-order kinetic models could describe well the TC adsorption process, in which chemisorption was the major driving factor, with the maximum adsorption at 23.56 mg g−1. The improved photo-catalytic capability owed to the formation of Z-scheme heterojunctions with ZnFe2O4 and CuWO4, which improved the intensity of visible light absorption and enhanced the separation electron-hole pairs as well as the redox capability of the composite. ZW-40 was high stability as its removal ability of TC in different water conditions slightly dropped about 15% after 5 cycles. ZW-40 could effectively remove TC in different water matrix, its removal ability for 40 mg/L was as follows: super-pure water\u3e municipal wastewater\u3e swine farm wastewater. Hence, the complexation of ZnFe2O4 with CuWO4 provides a valuable strategy to improve the photocatalytic potential for ZnFe2O4-based catalysts as well as providing a promising pathway for water clarification.https://opus.govst.edu/fac/1167/thumbnail.jp
High-Quality Reference Genome for an Arid-Adapted Mammal, the Banner-Tailed Kangaroo Rat (Dipodomys spectabilis)
No full textKangaroo rats in the genus Dipodomys are found in a variety of habitat types in western North America, including deserts, arid and semiarid grasslands, and scrublands. Many Dipodomys species are experiencing strong population declines due to increasing habitat fragmentation, with two species listed as federally endangered in the United States. The precarious state of many Dipodomys populations, including those occupying extreme environments, make species of this genus valuable subjects for studying the impacts of habitat degradation and fragmentation on population genomic patterns and for characterizing the genomic bases of adaptation to harsh conditions. To facilitate exploration of such questions, we assembled and annotated a reference genome for the banner-tailed kangaroo rat (Dipodomys spectabilis) using PacBio HiFi sequencing reads, providing a more contiguous genomic resource than two previously assembled Dipodomys genomes. Using the HiFi data for D. spectabilis and publicly available sequencing data for two other Dipodomys species (Dipodomys ordii and Dipodomys stephensi), we demonstrate the utility of this new assembly for studies of congeners by conducting inference of historic effective population sizes (Ne) and linking these patterns to the species’ current extinction risk statuses. The genome assembly presented here will serve as a valuable resource for population and conservation genomic studies of Dipodomys species, comparative genomic research within mammals and rodents, and investigations into genomic adaptation to extreme environments and changing landscapes.https://opus.govst.edu/fac/1100/thumbnail.jp
