Piercing sheet glass under high pressure.

High performance under pressure.

Nanomaterials under high-pressure.

The use of high-pressure for the study and elaboration of homogeneous nanostructures is critically reviewed. Size effects, the interaction between nanostructures and guest species or the interaction of the nanosystem with the pressure transmitting medium are emphasized. Phase diagrams and the possibilities opened by the combination of pressure and temperature for the elaboration of new nanomate...

Fretting wear in self-piercing riveted aluminium alloy sheet

Fretting wear in aluminium alloy AA5754 joined by self-pierce riveting (SPR), a relatively new fastening technique increasingly used in vehicle structures, has been investigated in this paper. Surface damages have been induced when a joint experienced a sinusoidal cyclic tension-tension load. Various degradation zones have been characterised in the contact surfaces between the aluminium sheets,...

Breathing under high ambient pressure.

LORD, GEORGE P., GEORGE F. BOND, AND KARL E. SCHAEFER. Breathing under high ambient pressure. J. Appl. Physiol. 21 (6): 1833-1838. 1966.—The acute effect of high ambient pressure on expiratory airflow was studied in healthy adult males in the ambient pressure range from 1.0 to 7.0 atmospheres absolute pressure (Ata) using a hyperbaric chamber. Changes in flow were assessed with the maximum expi...

Reducing the warp of sheet glass

Mireille Akilian Mark L. Schattenburg Abstract — Many leading technologies, such as flat-panel displays and precision optics, require sheet glass with exceptional surface qualities. Commercially available sheet glass of <1-mm thickness typically has a surface warp on the order of hundreds of microns, rendering it a challenge to utilize progressively thinner sheets. A novel method of shaping ind...
