The Material Measurement Laboratory (MML) and the NIST Center for Neutron Research (NCNR) encourage undergraduate STEM majors to participate in the Summer Undergraduate Research Fellowship (SURF) program at the NIST laboratories in Gaithersburg, MD. The MML/NCNR program is specifically designed to provide hands-on research experience in three topic areas. These are
Projects change every year according to MML/NCNR research needs. See below for examples of past SURF student project titles from recent years.
Students applying to the MML/NCNR SURF program are offered three programmatic choices: Chemical/Biochemical Sciences, or Materials Science (which includes projects at the NCNR), and Computational Materials Science.
Chemical/Biochemical Sciences: This concentration addresses the nation's needs for measurements, standards, technology development, and reference data in the areas broadly encompassed by chemistry, biotechnology, and chemical engineering.
Examples of past projects:
Project Description: In this project, we tested electrochemical sensors to be used in saliva or dental pulp tissues. Our goal was to measure the concentration of relevant biomarkers in order to provide more accurate and timely diagnosis of disease. The student worked with their mentor to prepare electrode sensors, test them in in physiologically-relevant relevant media, and then analyze the data, comparing results with calibration curves to determine parameters such as pH and concentration of protein biomarkers. The objective was to learn how to prepare and chemically modify electrodes as well as collect and analyze electrochemical data. (see page 63 of the 2019 student abstract book for results of this project).
Project Description: The student contributed to this project by assessing cell viability in scaffolds used for tissue engineering applications. They fabricated scaffolds, cultured cells in scaffolds, and conducted biochemical assays to assess cell viability in the scaffolds. The student worked with NIST scientists to design experiments and developed strategies for validating viability measurements. They prepared hydrogels, used microscopes, used plate readers, ran biochemical assays, analyzed data, generated plots, conducted statistical tests, and summarized findings. (see page 67 of the 2019 student abstract book for results of this project).
Project Description: To support an emerging program in food allergen measurements at NIST, the SURF student developed methods to quantify protein allergens in existing NIST food reference materials using antibody-based assays (ELISAs) and measurements using mass spectrometry (MS). The method development focused on using commercial antibody-based assays for milk proteins. Following immunoassay, mass spectrometry will be used to analyze the milk proteins, allowing for a direct comparison of measurement methods. The methods developed for milk protein allergens were then applied to measurements on existing NIST SRMs such a whole milk powder, infant formula, protein drink mix, and a food composite. (see page 75 of the 2019 student abstract book for results of this project).
Project Description: This project focused on developing and generalizing the metrology for characterizing cooperative rearrangements emerged universally in many condensed fluids, including glass-forming polymers of various architectures (linear, branched, star, and ring polymers), interfacial dynamics of crystals, internal dynamics of proteins, lipid membranes, superionic, driven granular fluids and colloidal hard sphere fluids. The objective was to learn the fundamentals of molecular dynamics simulations, glass-forming polymer and machine learning, and be involved in developing python codes to extract spatially correlated motion from molecular dynamics simulations of polymers in particular. (see page 60 of the 2019 student abstract book for results of this project).
Materials Science: This concentration focuses on synthesis, measurements, and theory of innovative materials and devices. Note: This concentration includes projects from the NCNR. Additionally, a limited number of projects are available at the NCNR for students with interest in nuclear engineering and/or reactor operations.
Examples of past projects:
Project Description: The student’s responsibility included the preparation and evaluation of electrochemically deposited Cu catalysts for In-situ Surface Enhanced Raman Spectroscopy/CO2 electroreduction experiments. This entails the preparation of electrolyte solutions, assembling electrochemical cells, and applying constant potential or current through gas-diffusion layers, which serve as the plating substrate. (see page 68 of the 2019 student abstract book for results of this project).
Project Description: The elemental characterization of glass evidence is an important tool in forensic science that allows practitioners to associate or discriminate a known and questioned glass sample. The micro-heterogeneity of glass is important when considering sampling and analysis strategies, since the analysis of small areas of a glass specimen should be representative of the bulk composition. This project focused on the elemental analysis of glass specimens to evaluate the micro-heterogeneity of the samples and ultimately assess the risk of false exclusions. (see page 70 of the 2019 student abstract book for results of this project).
Project Description: Marine plastic pollution is a growing issue, and researchers need the best methods for quantifying and characterizing plastic in complex environmental samples. The student analyzed Fourier transform infrared (FT-IR) spectra of plastic marine debris collected from Hawaiian beaches. The FT-IR spectra of over 3000 items contain a wealth of information that can help understand how old the debris is (when it was littered) and how toxic it might be to animals that eat it (additives). The existing spectra were examined for a carbonyl index to validate our visual weathering codes and for brominated flame retardant additives that are known to be toxic to the thyroid system. In addition to this project, the student also assisted four on-going plastic marine debris projects. (see page 69 of the 2019 student abstract book for results of this project).
Project Description: The Neutron and X-ray Tomography (NeXT) system provides the ability to produce simultaneous, dual-modality, tomography datasets. The Neutron Imaging Team has created a MATLAB based tool that allows users to draw polygons around regions of interest in the 2D bivariate histogram to isolate phases (materials) of interest. The tool will process an entire volume and produce individual binary volumes for each polygon drawn on the histogram. While this tool provides a convenient way to begin the segmentation process, it lacks the ability to distinguish individual peaks that would indicate a region of interest. For this project the student expanded on this segmentation tool through the exploration of methods to improve the identification of peaks and points of inflection. (see page 77 of the 2019 student abstract book for results of this project).
Computational Materials Science: This concentration includes the application of modeling, simulation, and computational methods to enhance our understanding of innovative materials and devices. Note: This concentration includes projects within the Materials Genome Initiative.
Examples of past projects:
Project description: The student learned to use the LAMMPS molecular dynamics simulation software and help develop Python scripts for testing interatomic models. The developed calculation methods then served as standard tests for evaluating and comparing the different models. (see page 66 of the 2019 student abstract book for results of this project).
The NIST SURF Program will have options for either in-person or remote for Summer 2023. Application packages will be submitted directly by the students through USAJOBS (Announcement #: Gaithersburg: SURF-2023, Boulder: SURF-2023). To apply for opportunities on USAJOBS, all applicants are required to have a profile (account creation details). When applying, students should indicate their first- and second-choice programs from among the possible choices. Applications may be considered by any of the programs, with preference given to the student's indicated first choice.

The NCNR is a major national user facility and resource for industry, universities, and government agencies with merit-based access made available to the entire U.S. technological community. Neutrons are powerful probes of the structure and dynamics of materials ranging from molecules inserted into membranes mimicking cell walls to protons migrating through fuel cells. The unique properties of neutrons can be exploited by a variety of measurement techniques to provide information not available by other means. They are particularly well suited to investigate all forms of magnetic materials such as those used in computer memory storage and retrieval. Atomic motion, especially that of hydrogen, can be measured and monitored, like that of water during the setting of cement. Residual stresses such as those inside stamped steel automobile parts can be mapped. Neutron-based research covers a broad spectrum of disciplines, including engineering, biology, materials science, chemistry, physics, and computer science. Current experimental and theoretical research is focused on materials such as polymers, metals, ceramics, magnetic materials, porous media, fluids and gels, and biological molecules.
