Passive samplers, for instance Chemcatcher, Microporous Polyethylene Tube passive samplers (MPTs) and Diffusive Gradients in Thin Films (DGT), are widely used for monitoring time-weighted average concentrations (CTWA) of contaminants in waters. This study presents ChemTRAP, a novel passive sampler using two macroporous filters (MFs) as both sorbent suppor ...

Co-pollution of nitrate and tetracycline (TC) poses a critical barrier to efficient biological treatment due to impaired electron transfer, diminished microbial metabolic activity, and disrupted community structure. To address this challenge, this study synthesized an iron-nitrogen-doped carbon material (Fe-NC) featuring electron-withdrawing pyridinic nit ...

Marine oil spills are one of the most severe anthropogenic threats to oceanic ecosystems, coastal communities, and global economic stability. While traditional monitoring and response approaches have played a foundational role in oil spill management, their effectiveness is often constrained by l ...

Non-electrically driven samplers, commonly known as passive samplers, are widely used in surface water monitoring to determine the Time-Weighted Average Concentration (CTWA) of contaminants. In this study, we developed an evaporation-driven sampling system and methodology, comprising an Evaporation-Driven Sampler (EDS) for sampling and its standard versio ...

Biological denitrification is limited by slow nitrate (NO3-) reduction due to low electron transfer efficiency, unsatisfactory community functional efficiency and insufficient metabolic activity of microbial communities. To overcome these challenges, Ni2+ and Fe2+ were incorporated with gallic acid (GA) to form bimetallic polyphenol networks (NiFeGA BPNs) ...

The widespread use of plastics and their improper disposal have released a large number of micro- and nano-plastics (MNPs) into various environmental media. Although the release of MNPs from individual plastic products has been widely reported, there is a lack of a holistic assessment framework to determine the overall release of plastic products to soil, ...

Plastic pollution in aquatic environments has become a growing global concern, with floating macroplastics posing serious ecological, economic, and health risks from inland water bodies to remote coastal zones. Despite advances in satellite remote sensing, reliable and scalable detection of floating plastics remains limited by spectral confusion and the l ...

Indexable face milling tools are often used to machine workpieces with large axial and radial depth of cuts, and thus, the inserts quickly wear out in machining. A kernel technique of smart machining is tool wear compensation, which is to regularly and automatically measure the insert radius/length with a laser tool setter on the machine table during mach ...

Inefficient electron transfer is one of the main challenges in practical denitrification applications. To address this issue, a novel ternary mediator functional material (Mxene@Fe-TA) was successfully synthesized, which exhibited pseudocapacitive properties to facilitate electron mediation and distribution. Batch experiments revealed that 50 mg/L MXene@F ...
