BAM Federal Institute for Materials Research and Testing lists the world-wide available nano-scale reference materials on its website
BAM has listed the world-wide commercially available nano-scale reference materials on its website as well as links to manufacturers and vendors: http://www.nano refmat.bam.de
Nanotechnologies stand at the threshold to industrial use. Standards help convert innovations into marketable products. BAM intensively supports the international standardization for nanotechnologies (for example in ISO/TC 229 Nanotechnologies or CEN/TC 352 Nanotechnologies). New requirements arose for calibrating the highly sensitive measurement procedures used in nanotechnologies.
About 65 nano-scale reference materials of different categories (step grating, nanoobjects, porosity...) are currently listed under the above link. Certified reference materials (CRMs) of the highest quality are included and these are usually offered by the national and European metrological state institutes (PTB/BAM, IRMM, NIST, AIST,...). Reference materials offered by companies or research institutes where the data necessary from a metrological point of view may be incomplete are also included. The compilation is being updated regularly.
A data sheet in pdf format can be downloaded for each reference material. The sheets contain quantitative data on the mean value and uncertainty, information about the area of application and links to the respective manufacturer/vendor.
Suggestions, criticism or comments to the reference material list are welcome.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale
Researchers from the Institute of Organic Chemistry and Biochemistry of the CAS (IOCB Prague), Institute of Physics of the CAS (IP CAS) and Palacký University...
For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
