11. Measurement Science Needs for the Expanded Use of Green Concrete: Workshop Summary Report
Series: Technical Note (NIST TN)
Report Number: 1783
Topic: Chemistry
Published: 2/6/2013
Authors: Kenneth Alan Snyder, Dale P Bentz, Jeffrey W Bullard, Chiara F Ferraris, Nicos Martys, Paul E Stutzman
Abstract: In July 2012, NIST conducted the Green Concrete Workshop to bring together stakeholders from the concrete construction industry and identify critical needs for the expanded use of industrial by- product materials, such as fly ash and slag, in conc ...

12. Improving Concrete Bridge Decks with Internal Curing
Topic: Chemistry
Published: 2/1/2013
Authors: Jason Weiss, Dale P Bentz, Carmelo DiBella
Abstract: Transportation agencies strive to provide durable, long lasting concrete bridge decks. While high performance concrete is frequently desired due to its resistance to chloride ingress and corrosion, these mixtures are often accompanied with an increa ...

13. To Predict Vibrational Spectra, Are Anharmonic Calculations Worthwhile?
Topic: Chemistry
Published: 1/22/2013
Authors: Ruth Lafuente Jacobsen, Karl K Irikura, Russell D Johnson III, Raghu N Kacker
Abstract: Anharmonic calculations using vibrational perturbation theory are known to provide near-spectroscopic accuracy when combined with high-level ab initio potential energy functions. However, performance with economical, popular electronic structure meth ...

14. ELUCIDATING THE SURFACE COMPOSITION OF MECHANICALLY MODULATED COLLAGEN FIBRIL FILMS WITH TOF-SIMS
Topic: Chemistry
Published: 1/17/2013
Authors: Christopher R Anderton, Kiran Bhadriraju, Frank W DelRio, Anne L Plant
Abstract: The extracellular matrix (ECM) environment plays a critical role in organism development and disease. Consequently, developing complementary analytical techniques to study bioactive scaffolds can assist in understanding cell-ECM processes. We have ...

15. Weathering Patterns of Ignitable Liquids with the Advanced Distillation Curve Method
Series: Journal of Research (NIST JRES)
Report Number: 118.003
Topic: Chemistry
Published: 1/17/2013
Authors: Samuel Allen, Thomas J Bruno
Abstract: One can take advantage of the striking similarity of ignitable liquid vaporization (or weathering) patterns and the separation observed during distillation to predict the composition of residual compounds in fire debris. This is done with the ad ...

16. Identifying improved standardized tests for measuring cement particle size and surface area
Topic: Chemistry
Published: 1/14/2013
Authors: Chiara F Ferraris, Edward Joseph Garboczi
Abstract: The Blaine fineness (Blaine) of a cement powder is a single parameter that is meant to characterize the specific surface area of a cement, and is assumed to be linked to physical and mechanical properties such as strength, setting time, and rheology. ...

17. Protective performance of environmentally stressed fabrics containing melamine fiber blends
Topic: Chemistry
Published: 1/12/2013
Authors: Shonali Nazare, Shaun M. Flynn, Rick D Davis, Joannie W Chin
Abstract: In this study, environmentally stressed OS fabrics containing melamine fiber blends were evaluated for thermal and mechanical properties that are critical to the protective performance of firefighter turnout gear. Environmental stress factors that a ...

18. Quantifying Residual Stress Development and Reserve Strength in Restrained Internally Cured Concrete
Topic: Chemistry
Published: 1/1/2013
Authors: John Schlitter, Dale P Bentz, Jason Weiss
Abstract: Concrete can develop tensile stress when it is restrained from shrinking freely. Standard tests, like the restrained ring test (ASTM C1581-09) can be used to quantify how likely a mixture may be to crack under constant temperature conditions. The s ...

20. Low-frequency noise in gallium nitride nanowire mechanical resonators
Topic: Chemistry
Published: 12/7/2012
Authors: Jason Gray, Kristine A Bertness, Norman A Sanford, Charles T. Rogers
Abstract: We report on the low-frequency 1/f (flicker) parameter noise displayed by the resonance frequency and resistance of doubly clamped c-axis gallium nitride nanowire (NW) mechanical resonators. The resonators are electrostatically driven and their mech ...
