Hotter Cements, Cooler Concretes

Author(s)
Dale P. Bentz, Casimir Bognacki, Kyle Riding, Victor Villarreal
In the past 50 years, portland cements have become progressively finer, in order to meet increasing demands for fast-track construction, etc. While finer

On-chip CO2 control for microfluidic cell culture

Author(s)
Samuel P. Forry, Laurie E. Locascio
Carbon dioxide partial pressure (PCO2) was controlled on-chip by flowing pre-equilibrated aqueous solutions through control channels across the device. Elevated

A Compact Variable-Temperature Broadband Series-Resistor Calibration

Author(s)
Nathan D. Orloff, Jordi Mateu, Arkadiusz C. Lewandowski, Eduard Rocas, Joshua P. King, Dazhen Gu, Juan C. Collado Gomez, Ichiro Takeuchi, Xiaoli Lu, James C. Booth
We present a method to obtain a broadband on wafer calibration from 45 MHz to 40 GHz for variable temperature, which requires three standards: a thru-reflect

This article describes an investigation of the transient behavior of a small (2.0 W at 85 K) Pulse Tube cryocooler operating at 120 Hz with an average pressure

Urban trees and the risk of poor birth outcomes

Author(s)
Geoffrey Donovan, Yvonne Michael, David Butry, Amy Sullivan, John Chase
This paper investigated whether greater tree-canopy cover is associated with reduced risk of poor birth outcomes in Portland, Oregon. Residential addresses were

Evaluation of Sustainable High-Volume Fly Ash Concretes

Author(s)

Effects of Polymeric Nanogratings on Cell Orientation

Author(s)
Nancy J. Lin, Sheng Lin-Gibson, Jirun Sun, Yifu Ding
Surface topography is known to play a critical role in the biological response to materials, with surface features on the order of both microns and nanometers

Development of a Four-channel System for Johnson Noise Thermometry

Author(s)
Alessio Pollarolo, Chiharu Urano, Paul Dresselhaus, Jifeng Qu, Horst Rogalla, Samuel Benz
Long integration time is necessary to reach low uncertainty when measuring temperature through Johnson Noise Thermometry (JNT). The main goal of the NIST JNT
