Nanotechnology
- J. Gilman
- 1 June 2001
Nanotechnology is the set of technologies that enables the manipulation, study or exploitation of very small (typically less than 100 nanometres) structures and systems. To put this into perspective,… Expand
Mechanism of shear-induced metallization
- J. Gilman
- Materials Science
- 1 November 1995
It is well-known that volumetric compression converts insulators into metals (the Herzfeld-Mott transition). Not so well-known is the fact that finite shear strains have a similar effect. For… Expand
Designing Superhard Materials
- R. Kaner, J. Gilman, S. Tolbert
- Materials Science
- Science
- 27 May 2005
In their Perspective, [ Kaner et al. ][1] describe recent efforts to make a material that matches or exceeds the hardness of diamond. Such a material must contain highly directional, short, and… Expand
Design of hard crystals
- J. Gilman, Robert W. Cumberland, R. Kaner
- Materials Science
- 2006
Abstract Hardness is measured by indenting, or by scratching, a solid. In general, it is a measure of structural stability which, in turn, is determined by elastic stiffness, plastic resistance,… Expand
Disclination Loops in Polymers
Similar to the dislocations in polymers caused by chain displacement, disclinations are caused by chain kinking and twisting. Two simple kinds are considered, a twist disclination loop (due to chain… Expand
Osmium diboride, an ultra-incompressible, hard material.
- Robert W. Cumberland, Michelle B. Weinberger, J. Gilman, S. Clark, S. Tolbert, R. Kaner
- Chemistry, Medicine
- Journal of the American Chemical Society
- 27 April 2005
The need for wear- and scratch-resistant materials drives the quest for new superhard materials. In this work, we apply two design parameters to identify ultra-incompressible, superhard… Expand
Shear-induced metallization
- J. Gilman
- Chemistry
- 1 February 1993
Abstract It is well known that compression causes insulators and semiconductors to become metallic when the concentration of the matrix atoms (or of impurity atoms) reaches a critical value given by… Expand
Why Silicon Is Hard
- J. Gilman
- Chemistry, Medicine
- Science
- 10 September 1993
Compared with pure metals and ionic salts, covalent solids such as silicon are hard and brittle because dislocations do not move in them except at high temperatures. A satisfactory explanation for… Expand
