Characteristics, sources, and concentration prediction of endocrine disruptors in a large reservoir driven by hydrological rhythms: A case study of the Danjiangkou Reservoir.

Herein, we present the first systematic investigation to clarify the effect of hydrological rhythms on the concentrations and distributions of polycyclic aromatic hydrocarbons (PAHs) and phthalate esters (PAEs) in the Danjiangkou Reservoir. The results revealed that hydrological rhythms remarkably affected the PAH and PAE concentrations and distributions in the water body, wherein the PAH concentration peaked in the flood season while the PAE concentration remarkably increased in the dry season. This study represents methodological innovation, revealing significant heterogeneity of PAHs and PAEs across different water layers.

Oxygen vacancy-rich Fe(MoO) combined with MWCNTs for electrochemical sensors of fentanyl and its analogs.

Hundreds of thousands of people dying from the abuse of fentanyl and its analogs. Hence, the development of an efficient and highly accurate detection method is extremely relevant and challenging. Therefore, we proposed the introduction of oxygen defects into Fe(MoO) nanoparticles for improving the catalyst performance and combining it with multi-walled carbon nanotubes (MWCNTs) for electrochemical detection of fentanyl and its analogs.

PVA/WO/AgWO Hydrogel for Enhanced Photocatalytic Disinfection and Accelerated Wound Healing.

Bacterial wound infections are one of the growing health and safety threats to the public. In this study, WO/AgWO photocatalysts were synthesized, and heterogeneous structures were constructed for non-antibiotic bactericidal use. Due to the heterostructure constructed with AgWO, the photogenerated carrier separation efficiency and reactive oxygen generation capacity of WO were improved, which in turn improved the inactivation rate of bacteria.

A series of ultrasensitive electrocatalysts Fe-MOF/MWCNTs for fentanyl determination.

Electrochemical determination of synthetic opioids such as fentanyl is meaningful but still challenging no matter from a social or academic perspective. Herein, we report a series of novel electrocatalysts based on Fe-containing metal-organic frameworks and multi-walled carbon nanotubes (Fe-MOF/MWCNTs). The obtained Fe-MOF/MWCNT electrode materials all show ultrasensitivity on fentanyl determination.

Chitosan Sponge/Cu-WO Composite for Photodynamic Therapy of Wound Infection.

One of the potential treatments for bacterial wound infections is photodynamic therapy. WO semiconductor materials can generate reactive oxygen species when exposed to light, which can inactivate bacteria. In this work, we improved their photocatalytic performance by doping WO with Cu.
