  • On the vibration assisted fluidisation of silica nanoparticles

    An experimental study was undertaken to investigate the process of vibration-assisted nanoparticle fluidisation. Fluidisation characteristics were assessed by measuring pressure drop, bed expansion and bed collapse behaviour at vibrational intensities between 0 Hz and 34 Hz, for silica nanoparticles with particle densities between 25 kg/m? and 38 kg/m?, and particle sizes of 7 nm and 16 nm. Two ...

  • Critical Review to Address Nanoparticles and Environment

    For a cautionary example of the paradox of innovation, look no further than asbestos, says Pratim Biswas, Ph.D. Asbestos—because of its unmatched strength, durability, and heat resistance—was long favored by the construction industry in a wide range of uses, ...


  • Influence of nanoparticles on the polymer-conditioned dewatering of wastewater sludges

    The effect of using small-scale, high surface area, nanoparticles to supplement polymer-conditioned wastewater sludge dewatering was investigated. Aerobically digested sludge and waste activated sludge sourced from the Hunter Valley, NSW, Australia, were tested with titanium dioxide nanoparticles. The sludge samples were dosed with the nanoparticles in an attempt to adsorb a component of the ...

  • Nanotechnology Briefing Paper Clean Water Act

    The purpose of this briefing paper is to evaluate the existing statutory authority under the Clean Water Act (CWA or Act) to regulate nanotechnology and nanoparticles.2 One of the stated national goals of the CWA is the elimination of the discharge of pollutants into the navigable waters. Accordingly, the CWA generally provides the U.S. Environmental Protection Agency (EPA) with authority to ...

  • Dangers of nanotechnology: potential fire concerns and safety frameworks

    The benefits of engineering of functional systems at the nanometre-scale as one of the key technologies of the 21st century almost always imply grave risks. The increasing speed of nanotechnology commercialisation and development has apparently outstripped the study of health and safety data. A potential hazard of nanopowders that appears to have received little attention so far is their ...

  • Nanotechnology – what is it? are there hazards?

    This is the first of a series articles on the emerging field of Nanotechnology. What is it? In short – small! Very small! Very, very small! Nanotechnology comes from the prefix Nano which, in English, means 1/billionth, just as micro means 1/millionth. So Nanotechnology involves 2 things: 1) extremely small man-made materials – some even as small as 1 atom thick, ...

  • Exploring Innovative Solutions

    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 ...


  • Green Nanotechnology: Straddling promise and uncertainty

    Nanotechnology has been called the second Industrial Revolution. Its seemingly limitless potential will continue to inspire innovations in a dizzying array of beneficial applications and briskly transform society. Despite the hope and promise nanotechnology brings, engineered nanoparticles, the tiny engines driving this new transformative technology, also generate a palpable apprehension due to ...

  • Thematic Issue: Nanomaterials’ Functionality

    Nanomaterials: addressing the challenges, benefiting from the opportunities Some of the deepest challenges we will face in the coming decades derive from the opportunities offered by emerging technological advances. Many of these will improve our quality of life, and develop our economies, but all will be measured against the overarching principle that we do not make some error, and harm ...

  • Opinion: Not such a small matter after all - Nanotechnology and the European Parliament

    By this time next year, the European Unions first provision on nano-Iabelling will be in force. From 11 July 2013, the new Regulation on cosmetic products1 will replace the old Cosmetics Directive,2 bringing with it the requirement that cosmetic products containing nanomaterials are labelled 'nano' before being placed on the EU market. Nanotechnology is an umbrella term used to describe the ...


  • 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 ...

  • FIFRA Scientific Advisory Panel considers nanosilver

    On November 3-5, 2009, the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Scientific Advisory Panel (SAP) met “to consider and review a set of scientific issues related to the assessment of hazard and exposure associated with nanosilver and other nanometal pesticide products.” The decision to convene an SAP was nominally motivated by the U.S. Environmental Protection Agency’s (EPA’s) ...

  • Reaching underground resources

    Accessing critical resources such as geothermal energy and natural gas requires drilling — an expensive, energy-intensive, messy process with today's technology. An MIT team has been looking into a more elegant approach. Instead of grinding rock to bits, they would use a continuous beam of energy to vaporize it and then blow out the tiny particles that form with a high-pressure stream of ...
