    as a plasticizer that reduces the interactions of polymer chains and allows for greater extension. WATER ABSORPTION. Researchers watched how the various postcured samples absorbed water at room temperature for up to one year. The water uptake of the ProtoTherm 12120 material was extremely low. The UV...
  • Drug Delivery: The "Great Equalizer"
    the polymer to release the active material. Access’ lead product, AP5346, a polymer-modified platinate oncology drug, is in Phase II testing. According to David Nowotnik, Ph.D., senior VP of R&D, this strategy allows 10-fold higher dosing compared with cisplatin, an old-line chemotherapy drug. Depomed...

    and minimizes metallic particle contamination. SIMS analysis is conducted to measure sodium, iron, and copper on the surface of stripped wafers. New Age nylon tubing features a moisture-absorption rate of 1.9% maximum @ 73 F. The tubing does not become brittle or swell as a result of contact with water...
  • Drug Delivery: The "Great Equalizer"
    the University of Kentucky School of Engineering, Cohen produced a multi-dose nasal delivery system which is as accurate as the Pfeiffer device, but provides up to 12 doses. ITI has applied this technology to four drugs: the anti-anxiety agents lorazepam and midazolam (both in Phase I testing), hydromorphone...

    reduces internal volumes to leave less surface area for moisture absorption to occur. No internal welds, seals, and fittings are needed, because all components and subsystems are mounted on common substrates.

  • No Such Thing as Too Quiet
    masks, for fiberglass installers. Polymer foams. High-density polymer foam is also a widely used insulator. Foam owes its acoustic absorption efficiency to its ability to fill the cavity into which sound waves propagate. The frequencies absorbed depend on the polymer material and the foam pore size, so...

    drop to a steady state. So they must be derived through actual testing. Frictional properties of thermoplastics differ from those of metals. Because thermoplastics have a lower modulus (more flexibility) and are softer than metals, they do not follow the classic laws of friction as applied to metals...
