Chementator: A new coating for steel

Researchers at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; edlinks.chemengonline.com/5830-537) have developed a ceramic-based coating for steel and superalloys that prevents corrosion, oxidation, carburization and sulfidization, which commonly occur in gas, liquid, steam and other environments. The low-cost, easy-to-apply material…

Chementator: Controlled polymerization

Warwick Effect Polymers (WEP; Coventry, U.K.; edlinks.chemengonline.com/5830-540) has licensed patented technology from Carnegie Mellon University (Pittsburg, Pa.; edlinks.chemengonline.com/5830-541) to exploit the commercial potential of atom-transfer radical polymerization (ATRP). ATRP is a controlled “living” polymerization involving radicals that can grow, but…

Important Determinants Of Solvent Selection  

    Early predictions suggested that solvents would eventually be eliminated from industrial applications because of health and environmental concerns. After a short period of a small decline in solvent use in 1990s, the solvent demand is now growing steadily…

Chementator: OLED breakthrough

DuPont (Wilmington, Del.; edlinks.chemengonline.com/5830-553) has demonstrated the ability to print small-molecule OLED (organic light-emitting diode) materials from solution. The printing process is said more scalable to large-display sizes and substantially less expensive than alternative processes, such as vapor deposition. DuPont…

Chementator: Pd catalyst

Sigma-Aldrich (St. Louis, Mo.; edlinks.chemengonline.com/5829-550) has commercialized an air- and water-stable palladium catalyst for performing intermolecular cross-coupling reactions, aminations and intermolecular Heck transformations. The catalyst, developed by Professor Michael Organ at York University (Toronto, Canada), is based on a Pd-NHC…

A multilayered, self-sensing diaphragm for metering pumps

Mechanically driven diaphragm pumps (MDDPs) are widely used for metering applications in the chemical process industries. But because the pressure difference between the drive and the delivery side gives rise to tensile loads in the flexing zone of the diaphragm,…

Don’t Overlook Composite FRP Pipe

    There are several reasons why composite fiberglass-reinforced-plastic (FRP) pipe has been replacing conventional pipe, and why this still relatively new material (see box, p. 46) should be kept in mind whenever piping is being specified for a new…
