The photocatalytic proficiency of BiTiO is hindered by its inadequate solar energy harnessing capability and swift electron-hole recombination dynamics. In the investigation, the study innovated Bi metal oxide heterostructures by embedding Bi nanoparticle-modified BiTiO composites, systematically synthesizing a suite of Bi/BT materials through meticulous tuning of the Bi and Ti precursor ratios. Notably, the Bi/BT-2 series was examined for its photocatalytic performance in tetracycline (TC) degradation. The findings revealed that Bi/BT-2 exhibited remarkable TC degradation efficiency, achieving a removal rate of 99.6 %, which surpasses BT-2 by a factor of 3.25 and TiO by 1.67 times. Mechanistic probing unveiled that the incorporation of nanostructured Bi onto the BiTiO surface introduced fresh active sites, dramatically bolstering the photocatalytic activity by augmenting the light absorption spectrum and refining charge separation processes. Moreover, an exhaustive examination of the TC degradation mechanism facilitated by Bi/BT-2 demonstrated sustained efficiency exceeding 80 % across a pH range spanning from 3 to 9, emphasizing its promising potential for practical applications. This study contributes invaluable perspectives for the design of cutting-edge metal-oxide photocatalysts tailored for environmental remediation purposes. Synopsis: The low degradation efficiency of tetracycline has posed a major challenge in bismuth titanate research. To address this, a novel approach was implemented by developing a BiTiO composite catalyst modified with Bi nanoparticles. This modification forms a metal-oxide heterojunction, which significantly enhances the degradation efficiency.
Background: Drought is one of main critical factors that limits sugarcane productivity and juice quality in tropical regions. The unprecedented changes in climate such as monsoon failure, increase in temperature and other factors warrant the need for development of stress tolerant cultivars to sustain sugar production. Plant Nuclear factor (NF-Y) is one of the major classes of transcription factors that have a major role in plant development and abiotic stress response.
Background: Increased ribosome biogenesis is required for tumor growth. In this study, we investigated the function and underlying molecular mechanism of ribosome biogenesis factor (RBIS) in the progression of non-small cell lung cancer (NSCLC).
Methods: In our study, we conducted a comprehensive analysis to identify key genes implicated in ribosome biogenesis by leveraging a Gene Set Enrichment Analysis (GSEA) dataset.
The visible-light-mediated continuous dehydration condensation and oxidative radical dimerization, featuring sulfur hexafluoride (SF) as both a condensation agent and oxidant, have been developed. This photocatalytic method uses commercially available N-protected amino acids as substrates and enables the formation of azlactone monomers and dimers, facilitating efficient utilization and degradation of greenhouse gas SF.
Replacing traditional plastic mulch with fully biodegradable mulch is an important research direction to solve the problem of "white pollution," but whether it can truly realize biodegradation is still the focus of many scholars. In this study, field and indoor experiments were carried out in Pingluo County, Ningxia Hui Autonomous Region, using poly（butyleneadipate-co-terephthalate） （PBAT） fully biodegradable mulch film and ordinary polyethylene （PE） mulch film, with no mulch film （CK） as the control. Macroscopic characteristics such as the degree of apparent cracking of the mulch film, loss of the mulch film area, and the rate of weight loss were observed, and the results were combined with the results of scanning electron microscopy （SEM）, Fourier transform infrared spectroscopy （FTIR）, and thermogravimetry （TGR）.
To efficiently remediate oil-contaminated soil, the degradation characteristics of petroleum hydrocarbons were explored using composite petroleum-degrading flora. The results showed that the degradation rates of the J0, H, HN, HK, and HKN groups were 9.82%, 33.
