Recently, the National Nanotechnology Standardization Technical Committee officially issued a document. With the approval of the National Standardization Administration Committee and the Chinese Academy of Sciences, it approved the establishment of a low-dimensional nanostructure and performance working group on the Taizhou Graphene Research and Testing Platform, numbered SAC/TC279/WG9, responsible and coordinated National standardization work on low-dimensional nanostructures and properties.

The recent work of the working group includes: organizing the formulation of a series of national standards for low-dimensional nanostructures, including general terminology for low-dimensional nanostructures, optical methods to determine the layer number distribution of low-dimensional nanostructures, transmission electron microscopy to determine the number of layers of low-dimensional nanostructures, Atomic force microscopy (AFM) method to determine the number of layers of low-dimensional nanostructures, testing methods for electrical properties of low-dimensional nanostructures, etc. Low-dimensional nanomaterials include zero-, one-, and two-dimensional materials. Zero-dimensional: all three dimensions are in nanometer size, such as clusters, quantum dots, nanoparticles, etc.; one-dimensional: two dimensions are in nanometer size, such as nanowires, nanorods, nanofibers, nanotubes, etc.; two-dimensional: one The dimension is in the nanometer size, such as ultrathin film, superlattice, graphene, molybdenum disulfide, hexagonal boron nitride, WS2, black phosphorus BP, WTe2, ReS2, ReSe2, InSe, etc.

At present, the website of Jiangsu Quality Supervision Bureau is openly soliciting members of the low-dimensional nanostructure and performance working group of the National Standards Commission. Deadline: December 29, 2016.
