Calibration Data for Wafer 2 of SRM 3461 - MEMS Cantilever Stiffness

Data provided by  National Institute of Standards and Technology

SRM 3461 is an AFM sized chip with an array of seven cantilevers on each chip. The uniformity of the chips offered for sale from wafer 2 is excellent and the SRM certificate reports values and uncertainties for the entire lot of chips for sale; however, this dataset provides the raw data used to certify the SRM. Since each chip is serialized, the raw data for a specific SRM chip can be accessed from this dataset. In addition to the laser Doppler vibrometry data and optical micrograph, this dataset contains the Mathematica code used to process the data.

ANDiE: the Autonomous Neutron Diffraction Explorer.

Data provided by  National Institute of Standards and Technology

ANDiE the Autonomous Neutron Diffraction Explorer is a tool for autonomously discovering the magnetic transition temperature and transition dynamics of a material from neutron diffraction experiments. The Jupyter notebooks used to implement ANDiE can be found here: https://github.com/usnistgov/ANDiE-v1_0 The Jupyter notebooks contained therein are of ANDiE as implemented at the WAND2 instrument at the HB-2C beamline at the High-Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory (ORNL).

2019 Annual Business Survey: Characteristics of Business

Data provided by  United States Census Bureau

The Annual Business Survey (ABS) provides information on selected economic and demographic characteristics for businesses and business owners by sex, ethnicity, race, and veteran status. Further, the survey measures research and development (for microbusinesses), new business topics such as innovation and technology, as well as other business characteristics. The U.S. Census Bureau and the National Center conduct the ABS jointly for Science and Engineering Statistics within the National Science Foundation.

Current Population Survey Annual Social and Economic Supplement

Data provided by  United States Census Bureau

The Annual Social and Economic Supplement or March CPS supplement is the primary source of detailed information on income and work experience in the United States. Numerous publications based on this survey are issued each year by the Bureaus of Labor Statistics and Census. A public-use microdata file is available for private researchers, who also produce many academic and policy-related documents based on these data.
