  • Nanotech and Jobs: Congress Weighs In

    The new Republication-led House of Representatives has expressed its concerns with what it refers to as the adverse impact of regulations on jobs and the economy. On February 10, 2011, this concern reached a new pitch. On this date, during a hearing on "Regulatory Impediments to Job Creation," the House Committee on Oversight and Government Reform released a preliminary staff report entitled ...

  • Genotoxicity assays analysis for carbon nanotubes: friends or foes? Preliminary results on human peripheral leukocytes

    The literature is full of information on the biological effects, both in vitro and in vivo, of Carbon Nanotubes (CNTs) and almost all the data published are in agreement on the toxicity related to physicochemical properties. The gap in the knowledge of the effects of CNTs on biological systems is instead evident when approaching the damage induced to DNA by CNTs. In fact, genotoxicity data is ...

    Progress in environmental management relies on innovation. Whether it's novel applications of new technologies, pioneering public policies, or groundbreaking partnerships – innovation leads to advances. Looking toward tomorrow's advances, the theme of A&WMA's ...


  • Tiny materials in countless products raise big questions for environment and health

    Nanotechnology opens a universe of possibilities — but also creates a world of unknowns. In recent years, efforts to develop the Next Big Thing — whether in medicine, computer technology, pollution prevention or high-performance materials — have turned to some really, really small things: nanomaterials. Working at the ...

  • Visible-light-driven photocatalytic water splitting on nanostructured semiconducting materials

    In view of the unlimited resource of solar energy and the abundance of water on earth, producing hydrogen through photocatalytic splitting of water under solar irradiation has the great potential to offer a low cost, environmentally friendly green fuel that does not contribute to greenhouse gas emissions. Since the pioneering work of Fujisima and Honda in 1972, tremendous research on ...

  • Reclamation of unconventional water using nano zero–valent iron particles: an application for groundwater

    Nano zero–valent iron (nZVI) is one of the most prominent examples of a rapidly emerging technology for the treatment of contaminated soil and groundwater. These particles were used successfully to absorb various heavy metals (e.g., Pb2+, Ba2+, As5+, As3+, Cr6+, Co2+, Cd2+, Cu2+), chlorinated organic contaminants (e.g., ...

  • Small concerns: Nanoscale materials as CECs

    Products are being designed, tested and sold today tluit make use of nanoscale materials and nanoscale properties. The more commonly discussed applications include nanoscale electronics, more efficient water and wastewater membranes, and other materials with tailor-made physical properties (such as weight, strength, etc.) unavailable by their 'macro' counterparts. Due to the explosive growth of ...

  • Effects of metallic and metal oxide nanoparticles in aquatic and terrestrial food chains. Biomarkers responses in invertebrates and bacteria

    Although the market of nanoparticles (NPs) is rapidly expanding, the environmental and health impact of manufactured NPs and nanomaterials is still poorly understood and predictable. Hence, several laboratories of the PACA region have unified their skills to address this issue with an interdisciplinary approach. We present an outline of the ecological impact of metallic and metal oxide NPs span ...

  • Good governance: evolution of the nanoscale materials stewardship program

    Governance issues are seldom the subject of wide consensus, and the question of how best the U.S. Environmental Protection Agency (“EPA”) should obtain needed information and data on the human health and environmental implications of nanoscale materials is no exception. EPA has considered the issue carefully and believes, with good reason, that a voluntary approach makes the most sense at this ...

  • Stable dispersions of single-walled carbon nanotubes

    The degree of dispersion of Single-Walled Carbon Nanotubes (SWCNTs) in different solvents is an issue in all studies where applications (in microelectronics, as well as in biological in vitro and in vivo systems) are envisaged. We performed long-term dispersion studies of SWCNTs in four different solvents: phosphate buffer solution (PBS), poly(sodium 4-styrene-sulfonate) (NaPSS), Gum Arabic (GA), ...

  • Equilibrium adsorption isotherm of U(VI) at pH 4 and pH 5 onto synthetic magnetite nanoparticles

    The adsorption features of synthetic magnetite nanoparticles have been investigated for removal of uranyl ions from nitric solutions. These magnetic nanoparticles can be used to adsorb contaminants in wastewater and can subsequently be removed from the medium by a magnetic process because of their superparamagnetic behaviour. The magnetite nanoparticles were synthesised by simultaneous ...
