Size at which Materials gain 'Nanospecific Properties' unclear, says Study endorsed by RIVM

chinese academy scienc 20120920A study commissioned by the Dutch National Institute for Public Health and the Environment (RIVM) has found that there is neither 'the experimental data nor the theoretical explanations' to determine the size at which 'properties [of materials] are changed to "nanospecific properties"'. The authority had funded this study so it could create 'size thresholds [that] can then be used to prepare the Dutch input into the foreseen review of the nanomaterial definition'.

The report, entitled What Defines Nanomaterials? concluded 'that physical chemical parameters...do depend on particle size at the nanoscale'. However, 'the particle size at which effects occur can vary with the property, the material tested, and the experimental conditions'.

nanoparticles in dangerNGOs recommend legislation for nanomaterials produced in 10 kg quantities. We recall the similar activities called "stop dihydrogen monoxide!".

No general nanomaterials legislation, EU concludes

europe flag-1350059751945A relief to a variety of companies regardless of their involvement in nanomaterials manufacturing or use: first week of October 2012, the European Commission came to a conclusion that no new legislation dedicated to nanotechnology is needed. The varying nature of nanomaterials does not allow putting all of them in one basket. Case-by-case studies are needed to assess risks associated with the use or production of each specific type of nanoparticles. The communication, which responds to a 2009 demand by the European Parliament, was jointly presented by European Commissioners Antonio Tajani, Janez Potočnik, John Dalli, and Máire Geoghegan-Quinn.

Despite of the frustration of Greenpeace and consumer organizations, which are happy to ring the bell at any occasion, the decision of the European Commission sounds well thought and duly motivated. It does not either claim that all nanomaterials are not hazardous, rather concludes that no general claim on the increased risk due to the small size of the particles can be made.

Fresh Talent Program to Boost Sci-tech

Beijing, 20 September 2012

chinese academy scienc 20120920The Chinese government has launched a ten-year campaign to cultivate more than 10,000 talented individuals in scientific and technological fields in its latest effort to consolidate a foundation for the country's development.

The project, titled "National Plan for the Special Support of High-level Talent," aims to support 100 scientists who have made breakthroughs in leading fields and have the potential to become "world-class scientists," according to a statement released Wednesday after a meeting of the Central Coordination Group for Talent Work.

Other talent to be aided in the program will include 8,000 people who have made innovative achievements in science and technology, as well as leading figures in the philosophical and social sciences, education and engineering.

Another 2,000 people under the age of 35 who are deemed to have outstanding potential in research and technology innovation will also be covered by the program.

In addition to financial support for research projects and team construction efforts, the program will also require employers and related governmental departments to create more favorable policies regarding research, work evaluation and stimulus benefits.

The program is being jointly carried out by 11 Communist Party of China (CPC) and government departments, including the Organization Department of the CPC Central Committee and the Ministry of Human Resources and Social Security.

Describing the program as an important part of the country's strategy to boost national strength, Li Yuanchao, head of the Organization Department of the CPC Central Committee, called for strict selection criteria and procedures that will be convincing for insiders, as well as the public.

According to the statement, five departments, including the ministries of education and science and technology, will be responsible for reviewing applications and selecting program beneficiaries.
