The structures of the narrowest carbon nanotubes ever made have been assigned for the first time on the basis of atomically resolved transmission electron microscope images
Researchers from Japan are at the forefront of international efforts to establish standards for assessing the risks associated with nanomaterials. Adarsh Sandhu reports.
Is it possible to reconcile the caution of most scientists about their results with the demands of the media for headlines and the growing emphasis placed by funding agencies on the economic impact of research? Richard Jones urges scientists to be careful in their claims.
It is essential that governments continue to fund research that does not appear to have any obvious economic benefits, even in a field as focused on applications as nanotechnology.
The increasing emphasis on commercialization and market forces in modern universities is fundamentally at odds with core academic principles. Publicly funded academics have an obligation to carry out science for the public good, and this responsibility is not compatible with the entrepreneurial ethos increasingly expected of university research by governments and funding agencies.
Assembling long carbon nanotubes vertically in a low-density array has resulted in a near-ideal black material that may have light-harvesting applications
Theoretical calculations show that stable growth of single-walled carbon nanotubes requires strong bonds between them and the metal clusters from which they grow
