Summary of Expertise: Listed with other top experts in: 
Expert has experience using activated carbon, zeolites, and aerogels to remove chemical moieties from fluid streams. He has knowledge of how activated carbon will absorb different materials from fluids based on the precurser activated. He has worked with aerogels to selectively adsorb and/or catalyze specific chemicals from the fluid stream, in essence, acting as a "smart material." Expert has produced chemical warfare barrier fabrics (under contract with US Army Natick Labs) using activated carbon fiber to produce a nonwoven fabric that could be ultrasonically bonded to the shell and inner lining fabrics.

Expert's experience with aerogels comes from market development work for a client company finding value-add applications for these materials. Applications being commercialized include blending with metals to extend the useful life of metal filters 4X by preferential sorption of acids, specific adsorption of chemical moieties from water to undetectable levels, and selective gas removal in hot gas environments.


absorbent material

Expert has worked with chemicals that will adsorb and retain at least 20 times their weight in fluid. These materials are produced from a number of chemistries, including salts of acrylic acid, polyurethanes (polyoxethylene), carboxy-methyl cellulose (CMC), and natural gums (guar, for example). They can be in a number of material formats including powders, fibers, liquids, and others and can be combined to target specific levels of absorption rate, capacity, free swell, and gel strength. Typical applications are baby diaper and feminine hygiene, but they are starting to find homes in a number of industrial applications including filtration, protective apparel, and agricultural markets. Expert believes these industrial market applications are embryonic and of high value-add and are worth the effort of developmental investment. The commercial applications that Expert has developed include SAP materials used to remove water from aviation fuel, phase change materials for moisture control and comfort in apparel applications (both sportswear and protective apparel), and chemical spill products for environmentally protective spill kits.

superabsorbent material

While at Fram, Expert developed the Fram ExtraLife air filter material used in carborated engines. He had responsibility for the filter material that became the Wearguard oil filter, judged a Consumer Report's Best Buy. He also developed a high-capacity, high-efficiency transmission filter material from felt that changed the playing field (patent applied for).

Expert is experienced with fabric materials constructed from fibers without weaving or knitting processes. These fabrics are usually engineered to meet a market need. Typical fabric producing processes are broken out as polymer-to-fabric (spunbond, meltblown, hybrids of these) and polymer-to-fiber-to-fabric (drylaid, airlaid, wetlaid, hydroentangled).

Expert has consolidated fabrics using mechanical, thermal, and chemical methods, with product properties very much affected by the product manufacturing techniques selected. He has created and improved many types of nonwovens throughout his career, including airlaid, drylaid, wetlaid, felt, hydroentangled, and spunbonded materials. Expert led a team that received the Allied Corporation Chairman's Award for improvement and cost reduction of the Fram in-house filter media manufacturing program using statistical process control techniques. He also led a team that installed a hydroentanglement line to produce medical fabrics in a foreign country. The line was delivered on-time and within budget and is sold-out today. Expert's nonwovens experience is broad as he has designed, produced, marketed, and sold these products.
