H2O2-free photo-Fenton system for antibiotics degradation in water via the synergism of oxygen-enriched graphitic carbon nitride polymer and nano manganese ferrite

The use of antibiotics for beings is a most significant milestone in present era. However, owing to the chemical diversity and complexity, antibiotics removal from water has been an issue...

Towards broad-operation window for stable CO2 electroreduction to HCOOH by upcycling design of electroplating sludge derived Sn@N/P-doped carbon

Electrochemical CO2 reduction reaction (CO2RR) to HCOOH offers a promising strategy for the carbon-neutral cycle. Sn-based materials have been demonstrated for extensive studies of CO2RR to HCOOH, but great challenges...

Nanocellulose enhances the dispersion and toxicity of ZnO NPs to green algae Eremosphaera viridis

The widespread cellulose nanomaterials from industrial production and natural plant degradation inevitably lead to the accumulation of nanocellulose in aquatic environment. However, the effect of nanocellulose on the fate, transport...

A Theoretical Perspective of the Structure and Thermodynamics of Secondary Organic Aerosols from Toluene: Molecular Hierarchical Synergistic Effects

Toluene is an important constituent of liquid fuel, and it contributes to the formation of secondary organic aerosol (SOA) under photochemical conditions. However, the underlying mechanism of toluene SOA is...

Gut-microbial adaptation and transformation of silver nanoparticles mediated the detoxification of Daphnia magna and offsprings.

Despite the extensive studies on the toxicity of antibacterial silver (either ionic Ag+ or nanoparticle - AgNPs) at the cellular or organismic levels, little is known about their differences in...

The bioaccumulation testing strategy for nanomaterials: correlations with particle properties and a meta-analysis of in vitro fish alternatives to in vivo fish tests

This meta-analysis identifies linkages between the tiers in the bioaccumulation testing strategy.

Fate of copper in soil: effect of agrochemical (nano)formulations and soil properties

Nanotechnology may be used to design more performant copper agrochemicals. Assessing the benefits and risks of the novel nano-products requires a good understanding of their fate in soil relative to...

Traffic-Derived Magnetite Pollution in Soils along a Highway on the Tibetan Plateau

Anthropogenic magnetite nanoparticles have been identified to present in human brain and circulatory system, which are potentially linked with the incidence of neurodegenerative and cardiovascular diseases. Specifically, magnetite nanoparticles originated...

In Situ Observations of the Occlusion of a Clay-Sugar Compound within Calcite

The stability of soil organic matter (SOM) plays a key role in controlling global climate change as soil stores a large amount of organic carbon, compared with other ecological systems....

Boost CO2 Electroreduction towards C2+ Products via CO* Intermediate Manipulation on Copper-based Catalysts

The global warming problem due to greenhouse gases (GHGs), mainly CO2, appears to be a serious concern in our global society. Electrocatalytic CO2 conversion provides an environment-friendly approach to reduce...
