A program is proposed to investigate acoustic and mechanical properties off a class of materials for use as acoustic lens devices. the materials, syntactic foams, can be compositionally varied over wide ranges to affect the acoustic impedence, sound velocity, and attenuation. futhermore, this class… More

Versar proposes to examine the effectiveness of commercially available clays suspended in liquid media to remove organophosphorus poison, mustard, proteinaceous material, and polynucleotides from contaminated objects. this effectiveness will be evaluated by measuring and comparing the components of… More

Small particle coating technology recently developed at versar, inc. makes it possible to apply cobalt\iron alloys to the surface of small carbon particles in amounts approximately the size of individual magnetic domains. a 50\50 cobalt\iron alloy is a high permeability alloy that also has high… More
