Wet-Etch Figuring Optical Figuring by Controlled Application of Liquid Etchant
WET-ETCH FIGURING (WEF) is an automated method of precisely figuring optical materials by the controlled application of aqueous etchant solution. This technology uses surface-tension-gradient-driven flow to confine and stabilize a wetted zone of an etchant solution or other aqueous processing fluid on the surface of an object. This wetted zone can be translated on the surface in a computer-controlled fashion for precise spatial control of the surface reactions occurring (e.g. chemical etching). WEF is particularly suitable for figuring very thin optical materials because it applies no thermal or mechanical stress to the material. Also, because the process is stress-free the workpiece can be monitored during figuring using interferometric metrology, and the measurements obtained can be used to control the figuring process in real-time--something that cannot be done with traditional figuring methods.

Aerosol Chemical Characteristion on Board the Doe g1 Aircraft Using a Particle Into Liquid Sampler During the Texaqs 2000 Experiment.
Knowledge of aerosol chemical composition is key to understanding a number of properties of ambient aerosol particles including sources, size/number distribution, chemical evolution, optical properties and human health effects. Although filter based techniques have been widely used to determine aerosol chemical constituents, they generally cannot provide sufficiently fast time resolution needed to investigate sources and chemical evolution that effect aerosol chemical, size and number changes. In order to gain an ability to describe and predict the life cycles of ambient aerosols as a basis for ambient air quality control, fast and sensitive determination of the aerosol chemical composition must be made available. To help to achieve this goal, we deployed a newly developed technique, referred to as PILS (particle-into-liquid-sampler), on the DOE G1 aircraft during the 2000 Texas Air Quality Study (TexAQS 2000) to characterize the major ionic species of aerosol particles with aerodynamic size smaller than 2.5 {micro}m (PM 2.5). The results obtained are examined in the context of other simultaneously collected data for insights into the measurement capability of the PILS system.

Oral History Interview with Robert Eustace, January 13, 2001
The National Museum of the Pacific War presents an oral interview with Robert Eustace. Eustace joined the Navy in 1943 and received basic training at Camp Farragut. He received further training at photography school in Pensacola. Upon completion, he was assigned to the USS Suwannee (ACV-27) as a photographer’s mate. Eustace flew in the backseat of a Douglas SBD Dauntless divebomber throughout the war in the Pacific. On 20 October 1944 the Suwannee was attacked by Japanese planes. Eustace contends that the antiaircraft fire did more damage to their sister ship than to the planes. On the 25th the Suwanee was hit by multiple kamikaze planes. Eustace photographed the attack and then tended to the wounded. He filled in as a helmsman and got the ship back to dry dock. He returned to the war and recalls pushing damaged planes into the water at Ishigaki. He then walked through Nagasaki after it was leveled by the atomic bomb and joined the occupation forces in Yokosuka. Eustace returned home and was discharged in May 1946.
