Some people like plastic Christmas trees; others prefer real wood and needles. This year, NIST is printing a tree out of concrete. The tree is not only festive
Objective To improve residential and industrial building energy efficiency by decreasing measurement uncertainties of the thermal resistance of insulating materials and develop measurement techniques for innovative insulation materials and systems using PCMs. Technical Idea One of the most cost
Objective This project aims to improve techniques currently used for risk evaluation (including uncertainty quantification) and mitigation (including FRP retrofit) of structural systems and integrate them within the PBEE framework. The first phase of the project is focused on the development and
The intended impact of this project is to enable a rapid and convenient virtual computing environment for evaluating and optimizing cementitious materials. Substantial savings in time, materials (purchase and disposal), human resources, and money can be achieved by reducing the number of physical
Objective: Currently, it is impossible to accurately measurethe release of nanofillers from surface-damaged polymer nanocomposites. By 2014, this project will develop and implement measurement science to characterize, model, and predict surface damage and nanofiller release as a function of
