Here is a perfect example of how someone, who apparently doesn't understand or care much about the science, writes a sensational press release hyping nanotechnology by cherry-picking information and distorting issues. And all that to sell a product that doesn't even have to do with nanotechnology. Two days ago we ran a press release from Thomson Reuters about a brief report they compiled on patent data relating to nanotechnology in the cosmetics industry. Now, Thomson Reuters is in the business of selling information and information services products and applications. Their press release basically is advertising for their IP Market Reports. There is nothing wrong with that. What is very wrong, though, is the nonsense and unbalanced take on certain aspects on nanotechnologies. Let's take a closer look.
Tailing after emerging nanotechnology applications in biomedical and electronic industries, the construction industry recently started seeking out a way to advance conventional construction materials using a variety of manufactured nanomaterials. The use of nanotechnology materials and applications in the construction industry should be considered not only for enhancing material properties and functions but also in the context of energy conservation. This is a particularly important prospect since a high percentage of all energy used (e.g., 41% in the United States) is consumed by commercial buildings and residential houses by applications such as heating, lighting, and air conditioning. A recent review by scientists at Rice University has looked at the benefits of using nanomaterials in construction materials but also highlights the potentially harmful aspects of releasing nanomaterials into the environment.
Why does silicon, which usually shatters catastrophically like glass when fractured, suddenly change and show ductile fracture like metals when the temperature is increased? Large atomistic models that incorporate quantum mechanical effects of how atoms interact in the material have now unravelled the fundamental events that cause the sudden change from brittle cleavage to ductile dislocation emission at a crack tip in silicon. This research has revealed that at low temperatures, silicon fails under spreading of cracks, where atomic bonds are broken continuously such that fractures spread easily in the material. For temperatures beyond a critical point, however, this changes dramatically and rather than breaking atomic bonds, stacked planes of atoms in the silicon lattice are sheared altogether, shutting down the spreading of cracks and giving rise to a much more graceful mode of failure that resembles that of metals.
'You cannot have an appropriate social dialogue on nanotechnology without an open-minded, consistent and even audacious communication roadmap aiming to bring everyone in.' So begins the foreword to a new Communication Roadmap by the European Commission on communicating nanotechnology in Europe. The EC has now compiled a roadmap for communicating nanotechnology across Europe. It presents the focus, objectives, methodology and actions already in place and to be developed over the next few years. The 188-page document is structured into three main parts: Where are we now? Where do we want to be? and How do we get there? and provides a detailed overview of all relevant activities and initiatives existing or planned across Europe.
A European project has completed an extensive five-year study of the needs and opportunities for coordinating future research and development in nanomaterials science and nanotechnology for the advancement of technologies ranging from communication and information, health and medicine, future energy, environment and climate change to transport and cultural heritage. Based on the collaborative work of more than 600 experts from all over the world, the project has compiled an overall picture of the present and future developments in the large spectrum of nanomaterials. Although one of the foci was to highlight the important roles of advanced analytical equipment at European research infrastructures, especially at synchrotron radiation, laser and neutron facilities, the 500-page project report provides an excellent overview of the nanomaterials revolution that is upon us. This is one of the best, up-to-date primers on nanotechnologies!
One of the key issues in the young field of nanotoxicology is the lack of standards and definitions. Although there have been some efforts, there still is no coherent international approach to determining if and what risks are posed by what kind of nanotechnology materials. At the core of the problem are the serious challenges that are created when comparing test results and drawing conclusions without adequate standardization and nanomaterial characterization. Exemplifying this set of problems further, a new study shows that even the most basic set of data, the nanomaterial characterization information provided by the manufacturer, can't be relied on - something which shouldn't come as a complete surprise given the existing problems with characterization data.
Taking the patent land grab to a new level, the government of Greece today, April 1, filed a patent and trademark application for the term nanotechnology with the European Patent Office. The country is thereby seeking the right to prevent third parties from commercially exploiting these and related terms without paying royalties. Notwithstanding the moral high ground the Greek government is trying to occupy, observers note that the real reason for this surprising move is very simple and very down-to-earth: money. Cash-strapped Greece, on the brink of bankruptcy, is desperate for revenues. Greece's massive debt problem has shaken the entire euro zone and undermined the shared currency. Greece's public debt is so high that the country could default - with potentially dire results for the Euro.
Last year, NT-MDT Co. invited its AFM probe users to take part in an open contest of images obtained with their probes. Though equipment is important in gathering a great AFM image, the result also depends on the probe being used. The purpose of the contest was to compile the most intriguing images collected from ventures into the nano-universe with AFM tips. Another aim of the ProIMAGE Contest was to show a great variety of scientific and artistic results obtained with a wide range of specialized probes. A gallery of all images submitted to the contest, which now is closed, and the six winners can be seen on the ProIMAGE webpages. Here is a random selection of some visually stunning images from the 150 contest submissions.
