Micro and Nanoplastic Contamination and Its Effects on Freshwater Mussels Caged in an Urban Area

Journal of Xenobiotics, 2023
Plastic-based contamination has become a major cause of concern as it pervades many environments such as air, water, sediments, and soils. This study sought to examine the presence of microplastics (MPs) and nanoplastics (NPs) in freshwater mussels ...

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

NH3 release during the evaporation of different types of atmospheric precipitation: A case study in Changchun, China

Scientific Reports
Ammonia (NH3) is a key precursor of secondary inorganic aerosols. During precipitation, NH3 in the atmosphere can be captured by rain and converted to NH4 +, whereas during evaporation, NH4 + can become NH3 and be released again.

Removal of Steroid Hormone Micropollutants by an Electrochemical Carbon Nanotube Membrane Flow‐Through Reactor: Role of Concentration and Degradation Mechanisms

Advanced Functional Materials, EarlyView.
A flow‐through electrochemical membrane reactor equipped with a carbon nanotube membrane eliminates the mass transfer limitation, achieving removals >97.5% for steroid hormone (SH) micropollutants through electrochemical adsorption and degradation, over a broad initial concentration varying from 50 to 106 ng L−1.

Continuous‐Flow Photocatalytic Degradation of Glyphosate and Aminomethylphosphonic Acid Under Simulated Sunlight with TiO2‐Coated Poly(vinylidene fluoride) Membrane

Advanced Functional Materials, EarlyView.
Glyphosate (GLY) and its primary metabolite, aminomethylphosphonic acid (AMPA), are photodegraded using a poly(vinylidene fluoride) membrane with immobilized titanium dioxide (PVDF‐TiO2) in a continuous flow‐through operation under solar light. At optimized conditions, the PVDF‐TiO2 membrane achieved 95% GLY and 80% AMPA removal with •O2− as the ...
