A vacuum manifold for rapid world-to-chip connectivity of complex PDMS microdevices

January 1, 2009
Author(s)
Gregory A. Cooksey, Anne L. Plant, Francisco J. Atencia
The lack of simple interfaces for microfluidic devices with a large number of inlets significantly limits production and utilization of these devices. In this paper, we describe the fabrication of a reusable manifold that provides rapid world-to-chip

Advice from the CCL on the use of unstabilized lasers as standards of wavelength: the helium-neon laser at 633 nm

Edward F. Kelley
Measurement of a small black area on a white electronic display screen is often accompanied by serious contamination from veiling glare in the detector. The black measurement can be thousands of percent in error. Character-stroke-contrast or small-area

Clean Agent Suppression of Energized Electrical Equipment Fires

January 1, 2009
Author(s)
Gregory T. Linteris
The NFPA 2001 standard on the use of clean agents for the suppression of fires arose from the phase-out of Halon 1301. Standard methods exists for specifying the amount of clean agent required for Class A and Class B fires, but the recommendation for Class
