Themed collection Best Papers 2020 – Environmental Science: Nano
Harmonizing across environmental nanomaterial testing media for increased comparability of nanomaterial datasets
The chemical composition and properties of environmental media determine nanomaterial (NM) transport, fate, biouptake, and organism response.
Strategies for determining heteroaggregation attachment efficiencies of engineered nanoparticles in aquatic environments
Heteroaggregation of engineered nanoparticles with suspended particulate matter in theory and practice: a roadmap for understanding and determining attachment efficiencies.
The gut barrier and the fate of engineered nanomaterials: a view from comparative physiology
Despite the diverse structures and functions of the gut barrier in the animal kingdom, some common features of gut lumen chemistry control the behaviour of engineered nanomaterials, and with some potentially novel uptake pathways in invertebrates.
What will happen when microorganisms “meet” photocatalysts and photocatalysis?
In recent years, photocatalytic technology has been widely studied as an environmental restoration technology and energy production technology to solve the two crises of energy shortage and environmental pollution.
Inorganic salts and organic matter effects on nanorod, nanowire, and nanoplate MoO3 aggregation, dissolution, and photocatalysis
Inorganic salts (NaCl and CaCl2) and organic material (humic acid and extracellular polymeric substances) have differing effects on the aquatic stability and photocatalytic activity of structurally different MoO3 materials.
Comparative physiological and metabolomics analysis reveals that single-walled carbon nanohorns and ZnO nanoparticles affect salt tolerance in Sophora alopecuroides
Using physiology and metabolome analyses, we showed the promoting effects of single-walled carbon nanohorns and ZnO nanoparticles on plant growth and salt tolerance in Sophora alopecuroides seedlings.
Curvature-induced hydrophobicity at imogolite–water interfaces
The curvature of the imogolite external surface induces changes in its hygroscopic properties as compared to its planar counterpart gibbsite.
Polystyrene nanoplastics accumulate in ZFL cell lysosomes and in zebrafish larvae after acute exposure, inducing a synergistic immune response in vitro without affecting larval survival in vivo
Polystyrene nanoplastics are internalized in zebrafish liver cells, accumulating in lysosomes, and in zebrafish larvae but do not affect the larval suvival to a lethal infection.
Hierarchically porous electrospun nanofibrous mats produced from intrinsically microporous fluorinated polyimide for the removal of oils and non-polar solvents
An electrospun nanofibrous adsorbent with micro-, meso- and macropores and surface area of 565 m2 g−1 was developed for the rapid removal of crude oil from seawater.
Exposure medium and particle ageing moderate the toxicological effects of nanomaterials to Daphnia magna over multiple generations: a case for standard test review?
Pristine engineered nanomaterials (NMs) entering the aquatic environment become ‘aged’ during their lifetime via chemical, physical and/or biological process.
Emerging investigator series: ion diffusivities in nanoconfined interfacial water films contribute to mineral carbonation thresholds
Mineral carbonation reactivity trends and thresholds in nanoconfined water films delineated with in situ X-ray diffraction and molecular simulations.
Smectite clay pillared with copper complexed polyhedral oligosilsesquioxane for adsorption of chloridazon and its metabolites
Copper complexed polyhedral oligomeric silsesquioxane pillared smectite clay (Cu2+@POSS_SWy-2) exhibits excellent adsorption properties for chloridazon and its metabolites.
Release of TiO2 nanoparticles from painted surfaces in cold climates: characterization using a high sensitivity single-particle ICP-MS
Wet, cold or freeze-thaw conditions enhanced the release of TiO2 nanoparticles from outdoor painted surfaces.
Efficient removal of metal ions by capacitive deionization with straw waste derived graphitic porous carbon nanosheets
Graphitic porous carbon nanosheets derived from straw waste were developed for capacitive deionization.
Nanoplastics as a potential environmental health factor: effects of polystyrene nanoparticles on human intestinal epithelial Caco-2 cells
Our results show that both nPS are easily internalized by Caco-2 cells in a concentration-dependent manner, but no relevant toxic effects are observed under the analyzed exposure conditions.
The distinct role of boron doping in Sn3O4 microspheres for synergistic removal of phenols and Cr(VI) in simulated wastewater
Boron doped Sn3O4 microspheres constructed from nanoplates with an unexpected synergistic effect upon simultaneous removal of phenols and Cr(VI) in simulated wastewater.
