Exploring Novel, Hard, Acoustically Absorbent, Materials
… or ceiling material treatment that is more sound absorbent than other common surface treatments. To find a material answer to this desire an impedance tube was used to analyze the mid-frequency octave band absorption coefficients of various re-purposed existing materials and tiles created …

Oil Dries: A New Absorbent Material For Collection Of Ignitable Liquids From Semi-Porous Material
… For this purpose, two different solid oil dry absorbent materials, Instazorb and MAXXAbsorb, were researched for use of collection of ignitable liquid samples at a fire scene. These oil dries were spiked with different ignitable liquids (Coleman fuel, gasoline, kerosene, and diesel). Isolation …

Modeling of Herschel/Quincke-Liner Systems for the Control of Aft Fan Radiation in Turbofan Engines
… the most widely used technology is that of absorbent materials or liners. In recent investigations Alonso et al. have combined Herschel/Quincke (HQ) tubes with liners. This combination has the potential of effectively controlling pure tones and broadband noise in inlet sections of modern …

An Evaluation of Tape for the Collection of Ignitable Liquid Residues from Non-Porous and Porous Surfaces
… of hydrocarbons and include commonly encountered materials such as gasoline, diesel, and kerosene. In the event of a suspected arson, ILR may be found within the pores of materials at the crime scene such as concrete. Traditionally, the whole material is collected and packaged into air-tight …

Absorbent Household Materials For The Collection Of Ignitable Liquid Residues From Surfaces Of Varying Porosity
… (GC-MS). In this work, readily available absorbent household materials such as microfiber and paper-based products have shown to be effective in the collection of ILs from non-porous surfaces such as ceramic tile. Fibers from these materials are attached to a solid backing which ensures …
