With production of nanocomposites, the product life cycle, including recycling, becomes critical.
Nanoproducts – what is actually available to European consumers?
It remains unclear which kinds of nanoproducts are available on the European market, although this information is a prerequisite for any kind of exposure and risk assessment.
Aggregation and interactions of chemical mechanical planarization nanoparticles with model biological membranes: role of phosphate adsorption
Adsorption of phosphate on chemical mechanical planarization nanoparticles can significantly impact the interactions between the nanoparticles and model cell membranes.
Accumulation of zinc, copper, or cerium in carrot (Daucus carota) exposed to metal oxide nanoparticles and metal ions
The ionic forms of Zn, Cu, and Ce are transported into carrot taproots, while nanomaterial forms of ZnO, CuO, and CeO2 were largely screened by the taproot outer periderm layer.
Surface engineering superparamagnetic nanoparticles for aqueous applications: design and characterization of tailored organic bilayers
This work describes the synthesis and characterization of a rational series of surface tailored superparamagnetic nanoparticles, which have broad potential as platform materials for advanced environmental imaging, sensing, and remediation technologies, among others.
Formation of supported lipid bilayers containing phase-segregated domains and their interaction with gold nanoparticles
Here we describe a method to form phase-segregated domain-containing supported lipid bilayers on silica substrates and demonstrate that the presence of these domains can alter nanoparticle interaction with bilayers.
Effects of dysprosium oxide nanoparticles on Escherichia coli
Determination of Dy2O3 nanoparticles toxicity on Escherichia coli at different water chemistry and metabolic conditions. The results of this study provide strong evidence that Dy ions, released from the nanoparticles, are the main cause for impairing of the bacteria functions.
Engineered manganese oxide nanocrystals for enhanced uranyl sorption and separation
For the first time, this work develops and demonstrates precisely engineered manganese oxide nanoscale particles for the sorption of uranium, as uranyl, in water.
Synthesis and catalytic, antimicrobial and cytotoxicity evaluation of gold and silver nanoparticles using biodegradable, Π-conjugated polyamic acid
We hereby report a rapid and simple synthesis of silver (AgNPs) and gold nanoparticles (AuNPs) using conductive, electroactive and biodegradable poly(amic)acid (PAA) polymer as both the reductant and stabilizer.
Economic analysis of CNT lithium-ion battery manufacturing
Although MWCNT lithium battery costs increase when proactively preventing manufacturing worker exposures, costs per unit of specific energy decrease overall.
Surface modification of thin film composite forward osmosis membrane by silver-decorated graphene-oxide nanosheets
Antimicrobial thin film composite forward osmosis membrane is developed using silver-decorated graphene-oxide nanosheets coating.
Comparative life cycle assessment of silver nanoparticle synthesis routes
Life cycle assessment of eight nanosilver synthesis routes, both physical and chemical, with results scaled by mass and function.
Toxicity of exfoliated-MoS2 and annealed exfoliated-MoS2 towards planktonic cells, biofilms, and mammalian cells in the presence of electron donor
EDTA, as an electron donor, used for the first time in the antibacterial study of MoS2.
An integrated methodology for the assessment of environmental health implications during thermal decomposition of nano-enabled products
The regulatory framework of nano-enabled products should be based on properties of the nano-emissions during the product life-cycle rather than the properties of raw materials used in the product synthesis.
About this collection
This collection of selected papers are from the Sustainable Nanotechnology Organization (SNO) 2014 conference and the SUN-SNO-GuideNano 2015 conference. They highlight how sustainable nanotechnology is leading the way to address economic development, global food supplies, as well as energy and water challenges while leaving minimal footprints that can give rise to environmental degradation.
