Use of visible light photocatalytic nanomaterials in water treatment can be promising in treating contaminants. However, little research has been conducted examining the effects of more complex chemistries in the nanomaterial’s performance. In this work, the effects of inorganic salts (NaCl and CaCl2) and natural organic matter (NOM) such as humic acid (HA) and extracellular polymeric substances (EPS)

Comprehensive thermodynamic understanding of nuclear materials is paramount for long-term management of legacy nuclear waste and commercial spent nuclear fuel. Actinide oxides (AnO2(s)) are ubiquitous materials throughout the nuclear fuel cycle, yet existing thermodynamic data has noticeable discrepancies, creating uncertainty in environmental prediction of the fate of nuclear materials. The microstructure

The science linking thermochemical conversion of the large-scale industry oily sludge with applied materials has been improved in the last ten years. However, the traditional converting methods are hard to precisely control the composition and structure of oily sludge-based products during pyrolysis due to the complexity of the composition of the oily sludge. Here, a chlorinating calcination method

Correction for ‘Curvature-induced hydrophobicity at imogolite–water interfaces’ by Alejandro Fernandez-Martinez et al., Environ. Sci.: Nano, 2020, DOI: 10.1039/d0en00304b.

Studies have shown that environmentally and biologically relevant coatings on nanoparticle (NP) surfaces can significantly alter the physicochemical properties (e.g. dissolution and aggregation) of particles yet there remain some questions on how these coatings impact reactivity. In this study, we investigated molecular-level details of surface adsorption and surface reactivity of titanium dioxide

Graphene quantum dots (GQDs) are 0D materials belonging to the carbon-based family that present some interesting characteristics of graphene combined to a tunable bandgap emerging from their reduced size, which gives them final outstanding physical-chemical properties. Furthermore, GQDs can be combined with other materials to produce nanocomposites with remarkable properties and superior performance

Chemical functionalization is widely adopted to increase the hydrophilicity of fullerene for various applications. Protein-nanomaterials (NM) interaction is one of the very first issues after NMs enter biological systems, which determines their bio-effects and toxicity. To better understand the biological and environmental effects of fullerene, we investigated the influence of surface modification

Sustainable and "green" technologies for hydrogen peroxide (H2O2) production have aroused increasing interests, yet challenges prevail in production of H2O2 for environmental applications. In this study, tungsten selenide (WSe2) with few-layered microstructure was used as a new co-catalyst to synthesize H2O2 under visible light irradiation. The ultrathin WSe2 nanosheets was anchored onto the g-C3N4

Abstract Ultrathin two-dimensional (2D) porous materials that can efficiently capture harmful pollutants from aqueous solution are highly desired yet scarcely reported. Herein, 2D zeolitic imidazolate framework-67 porous nanosheets (ZIF-67-NS) were first applied as a promising adsorbent for arsenic (III) removal from water. An ultrathin structure was observed for the as-prepared ZIF-67-NS with an average

With the increasing use of zinc oxide nanoparticles (ZnO NPs) in industry, the NPs released into ecosystem were on the rise; thus, it exerted a potential impact on the ecological environment. Here, we investigated the physiological and molecular mechanisms underlying ZnO NP-mediated plant growth in tomato plants. Foliar spraying with ZnO NPs (20 and 100 mg/L) improved tomato growth by increasing chlorophyll
