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.

Stopping problem ice -- by cracking it

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...
Whispering gallery mode (WGM) resonators are used to make tiny micro-lasers, sensors, switches, routers and other devices. These tiny structures rely on a...
Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
