impact on its interaction with water; in
fact, it enhanced the copper’s thermal effectiveness by 30 to 40 percent.
“The finding is interesting from a fun-
damental point of view as well as for prac-
tical uses,” Ajayan said. “Graphene could
be one of a kind as a coating, allowing the
intrinsic physical nature of surfaces, such
as wetting and optical properties, to be re-
tained while altering other specific func-
tionalities like conductivity.”

Bluff Manufacturing Extends
its Powder Coat Capabilities
Bluff Manufacturing has been an innovative
provider of material handling and warehouse safety equipment to companies
throughout the U.S, Mexico, Canada,
Caribbean and South America since 1968.
The company is continuing this tradition by
taking its already successful powder coat
process and extending its capabilities from
12 feet up to 40 feet in height or length for
both the structural products such as mezzanines, stairways and handrails, and the
Crash Guard safety line. The powder coat
technology offers a higher quality, longer
lasting gloss finish than the standard spray
painting processes said the company. CW
