Oxford Nanotechnology Summer School 2010

Oxford University has announced the dates for its 2010 Nanotechnology Summer School. The Summer School Programme offers five one-day courses designed to introduce participants to the advances that are being made in the rapidly developing field of nanotechnology. The courses focus on nanotechnology for energy, biomedical nanotechnology and nanosafety.

FramingNano report on current and future challenges in nanotechnology governance

After two years of consultation, the FramingNano Governance Platform as the final outcome of the corresponding FP7 research project has been published. The Platform describes a heuristic process of how current and future challenges in nanotechnology governance can be identified, assessed and decided on, and proposes a number of strucutal elements to achieve this.

Smart capsules for water treatment with recyclable carbon nanotube cores

Among various nanomaterial candidates for water treatment, metal oxides have been widely used as removal agents for various heavy metal ions and their removal capacity was found to be relatively reliable. The removal mechanism for heavy metal ions is thought to be the formation of a strong bond between metal ions and metal oxide surfaces. This strong complexation is advantageous for complete removal of heavy metal ions but it presents a drawback if one wants to design a reusable agent by reviving the reaction site for heavy metal ions. Precisely because the removal mechanism is based on the strong complex formation between metal ions and oxide surfaces, recycling of these removal agents has proved to be difficult. Offering a potential solution, researchers have demonstrated a recyclable removal agent for heavy metal ions by fabricating a core-in-shell structure based on a core of carbon nanotubes and an iron oxide microcapsule structure.

Light sculpts three-dimensional crystals in nonlinear optical materials

Scientists from the University of Muenster and the Indian Institute of Technology have experimentally demonstrated for the first time the creation of 3D photonic crystals and quasicrystals with a plethora of geometries and forms purely by the action of light in a nonlinear optical material, which allows reconfigurable as well as scalable crystal and quasicrystal formation.

What we know about engineered nanoparticles’ health and environmental safety

In 2008, the Joint Research Centre, Institute for Health and Consumer Protection of the European Commission funded the project Engineered Nanoparticles: Review of Health and Environmental Safety (ENRHES). Last month, the ENRHES project released its final report. The overall aim of the ENRHES project was to perform a comprehensive and critical scientific review of the health and environmental safety of four classes of nanomaterials: fullerenes, carbon nanotubes, metals and metal oxides. The review considers sources, pathways of exposure, the health and environmental outcomes of concern, illustrating the state-of-the-art and identifying knowledge gaps in the field, in order to coalesce the evidence which has emerged to date and inform regulators of the potential risks of engineered nanoparticles in these specific classes.

Trapping sunlight with silicon nanowires

Solar cells made from silicon are projected to be a prominent factor in future renewable green energy equations, but so far the promise has far exceeded the reality. While there are now silicon photovoltaics that can convert sunlight into electricity at impressive 20 percent efficiencies, the cost of this solar power is prohibitive for large-scale use. Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab), however, are developing a new approach that could substantially reduce these costs.
