Nanometrology - FY 2003 Program and Selected Accomplishments

December 15, 2003
Author(s)
Clare M. Allocca, Stephen W. Freiman
The emphasis on nanotechnology around the world is leading to the development and commercialization of unique products based upon significantly smaller devices and material ensembles. Materials at the nanoscale in three dimensions (NEMS, MEMS), two

VAMAS: Accomplishments and Future Directions

November 1, 2001
Author(s)
Stephen W. Freiman, E A. Early
The Versailles Project on Advanced Materials and Standards (VAMAS) was created in 1982 to support trade through international collaboration in pre-standards research in advanced materials. VAMAS has become self-sustaining through Memoranda of Understanding

Ceramics Division FY 2000 Programs and Accomplishments

January 1, 2001
Author(s)
Stephen W. Freiman, S J. Dapkunas
The mission of the Ceramics Division is: Work with industry, standards bodies, academia, and other government agencies in providing the leadership for the Nation's measurements and standards infrastructure for ceramic materials. The range of ceramic

Fracture and the Structure of Silica

July 1, 2000
Author(s)
Stephen W. Freiman
Not only because of its historic and widespread use in applications where its strength and brittle nature are significant factors, but also because it is homogeneous in composition and structure, and isotropic in its properties, glass is an ideal medium in

Apparent Correlation of Fracture Toughness and Strength

August 1, 1999
Author(s)
R G. Munro, Stephen W. Freiman
An extensive collection of fracture toughness (KIc) and strength ( f) data for brittle materials has been used to examine the relation between the mean measured values of KIc and f. The two properties have been found to have a weak, but useful, empirical

Author(s)
Stephen W. Freiman
The mission of the Ceramics Division can be stated as follows:Work with industry, standards bodies, academia, and other government agencies in providing the leadership for the Nation's measurements and standards infrastructure for ceramic materials.The

Fracture Toughness Data for Brittle Materials

April 1, 1998
Author(s)
R G. Munro, Stephen W. Freiman, T L. Baker
Fracture toughness data, as represented by the critical stress intensity factor, K Ic, and the fracture energy, γ, have been compiled from publicly accessible sources for a wide range of brittle materials with an emphasis on structural ceramics and closely

1997 NIST Ceramics Division Technical Activities

January 1, 1998
Author(s)
Stephen W. Freiman
The 1997 NIST Ceramics Division Report is organized in the form of programs, emphasizing a desire to develop more extensive collaborations among both Division and Materials Science and Engineering laboratory personnel, and to conduct focussed activities on
