Author(s)
Nathan Bossa, Sipe M. Joana, Alan Kennedy, Treye Thomas, Christine O. Hendren, Mark R. Wiesner, Keana Scott, William Berger
Manufactured nanomaterials (MNMs) are incorporated as "nanofillers" into consumer products to enhance properties of interest. Multiwalled carbon nanotubes (MWCNTs) are known for their unique properties and have many applications in polymers. However, the

Improving packet synchronization in an NTP server

January 29, 2018
Author(s)
Andrew N. Novick, Michael A. Lombardi, Kevin Franzen, John Clark
A computer or dedicated client can use the Network Time Protocol (NTP) to synchronize an internal clock to a server that is synchronized by a 1 pulse-per-second (pps) signal from a national timing laboratory. Measuring an NTP server on a local area network

Advances in Thermal Imaging Technology in the First Responder Arena

February 19, 2017
Author(s)
Francine K. Amon, Nelson P. Bryner
The Building and Fire Research Laboratory (BFRL) at the National Institute of Standards and Technology (NIST) has been conducting research that will provide a quantifiable physical and scientific basis upon which industry standards for imaging performance

Testing of Cementitious Materials Using a Dynamic MEMS Micro Rheometer

May 17, 2016
Author(s)
Yong Sik Kim, Nicholas G. Dagalakis, Chiara C. Ferraris, Nicos Martys
Incompatibility of cementitious materials with admixtures often requires time consuming testing. Usually, several mixtures need to be prepared either using concrete or paste to determine the optimum high range water reducer dosage (HRWRA) and type. The

Thermodynamic Properties of 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone: Vapor Pressure, (p, ?, T) Behavior, and Speed of Sound Measurements, and Equation of State

September 30, 2015
Author(s)
Mark O. McLinden, Richard A. Perkins, Eric W. Lemmon, Tara J. Fortin
We report comprehensive thermodynamic property measurements of 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone. The p–ρ–T behavior was measured from T = (225 to 470) K with pressures up to 36 MPa using a two-sinker densimeter. These
