The design of metal-organic framework-derived metal oxides/sulfides is an effective approach for water remediation. A series of Fe-Ce composites (Fe-Ce-S-N) with cluster-like morphology were prepared with prussian blue analogue (PBA) as the precursor in a hydrothermal process. S doping promoted the conversion of Fe(III) to Fe(II), which greatly improved the performance of the Fenton-like reaction.

Black phosphorus (BP) nanomaterials are promising for biomedical applications owing to their extraordinary biodegradability. Although previous research has demonstrated changes in the physicochemical properties of BP due to degradation, the impact of degradation on BP interactions with biological systems remains unclear. In this study, we designed a set of BP nanomaterials with varying degrees of degradation

Nanoplastics (NPs) in the environment have attracted attention worldwide as a new class of pollutant. However, their impacts on aquatic organisms are only beginning to be unraveled. The current study investigated the toxic effects and mechanisms of action of polystyrene NPs (PS-NPs) on liver apoptosis and the intestinal histological structure and flora of the economically important eel Monopterus albus

While the use of engineered nanomaterials (ENMs) is expanding to various applications and commercial products, public concerns are raising on their potential hazards to the exposed humans. Dermal absorption is the principal entry route for ENMs derived from various consumer products whose direct contacts with skin are often inevitable. Rapid nanosafety assessment of ENMs at their early development

Wildfire causes detrimental problems to animals and plants. Nanoparticles with enzymatic activities were applied to repair the damage caused by fire and potentially degrade the produced pollutants. Kinetic studies revealed for the first time an allosteric mechanism of the nanozyme. The present work aims to reveal the advantage offered by the phosphatase-like (PL) nanozyme formed by baking L-cysteine

Microplastics pollution has aroused considerable attentions. Here, we develop a visible-light-driven photocatalysis and photothermal Fenton-like reaction method for their removal, utilizing α-Fe2O3 nanoflower on TiO2 with a hierarchical structure of inverse opal-like layer/nanotube arrays (α-Fe2O3/TiO2HNTAs film). Without external H2O2 dosage, nearly 100% degradation of 310 nm polystyrene (PS) sphere

Despite laws prohibiting its usage, butyltin (TBT) is a legacy pollutant and antifouling agent that is still prevalent in marine systems and has been shown to have negative effects on the ecosystem. The purpose of this study is to fill a vacuum in the literature by determining whether nanoplastic (NPs, <1000nm) can carry TBT, which might provides a new TBT exposure pathway to marine organisms. Adsorption

Organic ammonium salts which are formed from heterogeneous reactions are one of the important components of Nitrogen-containing organic compounds (NOCs) in atmosphere. In order to investigate the formation process of organic ammonium salts, a gas-flow system with Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) technique was applied to monitor the influence of simulated illumination

The growing application of nanocellulose in various industrial sectors with potential release into the natural environment demands for safety assessment and thus ecotoxicity. Here we tested two types of cellulose nanofibers, non-oxidized (CNF) and TEMPO-oxidized (TOCNF), by means of acute in vivo studies with the marine bivalve Mytilus galloprovincialis at 1 µg L−1 and 1 mgL−1 as respectively resembling
