The shape of aggregates, from whatever source, plays a crucial role in determining the properties of the composite material in which they are embedded (e.g...
An outline of NIST research in the area of structural performance of housing systems is presented in this paper. The performance of wood-frame houses in past...
Passive energy dissipation devices are used to reduce the damage from earthquakes by absorbing a portion of the earthquake-induced energy in structures. Wide...
The concept of an interphase region between an adherent and a matrix or adhesive was first introduced in 1972 by Sharpe. Since this introduction, the role of...
In 1963, Donald McIntyre of the NBS Polymers Division produced the first polymer molecular mass standards to be issued by NBS as Standard Reference Materials...
Dielectric constant and morphology of BaTiO3-polymer composite films were studied as a function of the filler concentration. The morphology of the films was...
The lifetime prediction model that has been developed for brittle materials implicitly assumes an initial flaw population from which, under the influence of an...
A novel methodology using a combination of high energy ion scattering x-ray reflectivity, and small angle neutron scattering is used to characterize the...
Calcium phosphate are funding increasing use as biomaterials, e.g. in the treatment of defective mineralized tissues. Crystaline hydroxyapatite (HAP) is...
To design nanocrystal nanosystems, a theory for nanocrystals is needed which can be applied to nanocrystals with atomic-scale variations in composition...
We condider the spontaneous emission of a quantum dot embedded in a cavity. Purcell and local-field effects are investigated using the coupled dipole method and...
