Aerogels: production, characterization, and applications ...

Apr 01, 1997  It just so happened that aerogels covered a range of η-values unattainable by either compressed gases or liquids.The index of refraction for aerogels spans from η≅1.006 to 1.1, corresponding to densities from 3 to 500 kg m −3.. The subsequent demand for this material prompted two groups to begin large scale aerogel production in the 1970's. D. Poelz produced 1.5 m 3 of silica

Use Flowchart for Better Production Management

Production management needs the assistance of flowcharts. Flowcharts help production managers better plan and coordinate the production process. For example, with flowcharts, they can easily recognize which part of the process leads to a poor efficency, so that they can make a decision to improve accordingly. Also, as flowchart shows every step ...
