Nanometer-sized structures, surfaces and sub-surface phenomena have played an enormous role in science and technological applications and represent a driving

Quantum for Pressure

Author(s)
Jay H. Hendricks, Patrick F. Egan, Jacob E. Ricker, Jack A. Stone Jr., Kevin O. Douglass, Gregory F. Strouse
A team of NIST scientists is working to fundamentally change the way that the unit of pressure is realized and disseminated, an effort that will lead to the

Perspectives for a new realization of the pascal by optical methods

Author(s)
Jay H. Hendricks, Karl Jousten, Jack A. Stone Jr., Patrick F. Egan, Tom Rubin, Christof Gaiser, Rene Schodel, James A. Fedchak, Jacob E. Ricker, Jens Fluegge, Stephen P. Eckel, Julia K. Scherschligt, Daniel S. Barker, Kevin O. Douglass, Gregory F. Strouse, Uwe Sterr, Waldimir Sabuga
Since the beginning of measurement of pressure in the 17th century, the unit of pressure has been defined by the relationship of force per unit area. The

An integrated and automated calibration system for pneumatic piston gauges

Author(s)
Yuanchao Yang, Robert G. Driver, John S. Quintavalle, Julia K. Scherschligt, Katie M. Schlatter, Jacob E. Ricker, Gregory F. Strouse, Douglas A. Olson, Jay H. Hendricks
Recently, a transducer-aided crossfloat (TAC) method for pneumatic piston gauges was proposed. The concept is to use a pressure transducer as a very short-term

Cell-based refractometer for pascal realization

Author(s)
Patrick F. Egan, Jack A. Stone Jr., Jacob E. Ricker, Jay H. Hendricks, Gregory F. Strouse
We describe a method for determining density of helium via measurements of optical refractivity. In combination with the nist-equation of state, this allows

Optimizing Data Logger Setup for Vaccine Temperature Monitoring

Author(s)
Michal J. Chojnacky, Luis Chaves Santacruz, W Wyatt Miller, Gregory F. Strouse
Accidental freezing of refrigerated vaccine represents a significant public and private healthcare cost. Freeze-damaged vaccines lose their effectiveness

Performance of a dual Fabry-Perot cavity refractometer

Author(s)
Patrick F. Egan, Jack A. Stone Jr., Jay H. Hendricks, Jacob E. Ricker, Gregory E. Scace, Gregory F. Strouse
We have built and characterized a refractometer that utilizes two Fabry-Perot cavities formed on a dimensionally stable spacer. In the typical mode of operation

Developing Microwave Photonic Temperature Sensors

Author(s)
John S. Quintavalle, Bernard J. Filla, Gregory F. Strouse, Zeeshan Ahmed
