With a surface composed of tightly packed nanostructures that resemble tiny nails, thus the term “nanonails,” University of Wisconsin–Madison engineers and their colleagues from Bell Laboratories have created a material that can repel almost any liquid. But with a jolt of electricity, the liquid on the surface slips past the heads of the nanonails and spreads out between their shanks, wetting the surface completely.

It is not uncommon for engineers to develop a new compound for maintenance or manufacturing purposes, but then find that they cannot control processes well enough to produce large enough batches to make it cost-effective. That was the case recently when the U.S. Air Force (USAF) developed a replacement material for tape around access panels on the B-2 bomber.

Operating helicopters in very difficult climatic conditions in Iraq and Afghanistan can result in the need to replace rotor blades after only 400 flying hours’ time because sand, grit, and gravel have such a severe abrasive effect. To improve the operating life span of the BERP III blades fitted to AgustaWestland Lynx helicopters, the type operated in both countries by British Forces, 3M has developed a protective polyurethane coating.

Article
The family of Parylene conformal coatings (N, C, and D) has been used as a rugged, reliable protection solution for a wide range of aerospace applications for more than 35 years. However, while these standard formulations still meet the coating requirements of most applications, some of the leading-edge technology in aerospace devices often need a little more.

The designers of a diesel-electric locomotive that Vossloh Locomotives debuted in 2007 reduced the chassis weight by 25% by using high-strength steels. The result is a locomotive that the company says provides better transport economics, more evenly distributed axle loads with lower wear of the rails, and better protection for the driver, due to improved deformation properties in the event of a crash.

The trend in the marketplace for molded silicone rubber parts clearly favors the increased use of injectable liquid silicone rubber (LSR) due to its ease of processability, design versatility, excellent quality, and lower system costs. A new class of highly fluorinated LSRs provides added fuel, oil, and solvent resistance for the most demanding mobility applications.

Composites have replaced metals in a wide range of applications, realizing considerable weight savings as well as associated cost and performance improvements. One factor that can limit the use of composites is their thermal or electrical conductivity properties. In particular, composites based on unidirectional tapes or 2-D laminates are often not suitable in areas where heat is generated.
