Electric ‘Smart’ Paper Picks Up on Pipe Leaks

Although spills inside a lab can often spell trouble, a University of Washington scientist found a way to turn an accidentally doused conductive material into an inventive new sensor. The lab mishap led to a “smart” paper that conducts electricity and provides wireless detection of water pipe leaks.

Synergistic Coatings Meet Demanding Aerospace Challenges

Aerospace and airframe manufacturers know how difficult it is to design components that can withstand extreme environments while providing corrosion and wear protection. Making things even more complicated is the need to comply with international standards, such as REACH. While engineers favor composites, aluminum, titanium and magnesium for their light weight, most of these metals are highly susceptible to corrosion if left unprotected. A new white paper explores how applying synergistic surface enhancement coatings can address and overcome these industry challenges.

A Semiconductor Breakthrough: Carbon Nanotubes Boost Thermoelectric Performance

In a report published in October, scientists from the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) used single-walled carbon nanotubes (SWNCTs) to advance the thermoelectric performance of organic semiconductors. The carbon nanotube thin films, they said, could ultimately be integrated into fabrics to convert waste heat into electricity or serve as a small power source.

Specialized Materials Meet Critical Packaging Needs in MEMS Devices

The unique requirements of microelectromechanical systems (MEMS) call for specialized materials. Versatile epoxy adhesives are often capable of providing the necessary properties to ensure support and protection from thermal and mechanical shock, vibration, high acceleration, particles, and other physical damage. Download Master Bond’s white paper to find out how these materials are used and their benefits for MEMs applications.

Specifying & Achieving Desired Extrusion Performance

Since 2012, the usage of extruded aluminum shapes in North American light vehicles has grown by more than 50%, to over 25 pounds per vehicle. Today, aluminum extrusions can be found in applications as varied as crush cans, trim members, rocker sections and seat backs – each with a unique set of performance requirements. As automotive aluminum extrusion applications continue to grow, engineers seeking optimized performance are increasingly going beyond the “shorthand” of alloy and temper designation and specifying the desired microstructure for the final component.
