Rare Material Could Shorten Air Travel Times

An average flight from Miami to Seattle takes about six hours and 40 minutes, but imagine being able to reduce that time to 50 minutes or less. A recent study by NASA and Binghamton University researchers focuses on boron nitride nanotubes (BNNTs).

Strong and Stretchable “Super Steel”

In aerospace applications of materials, increasing strength often leads to a decrease in ductility. Engineers have developed a Super Steel that addresses this strength-ductility tradeoff. In addition to the substantial improvement of tensile properties, the steel has low raw-material cost and simple industrial processing.

Energized Fabrics Could Keep Soldiers Warm in Frigid Climates

Soldiering in arctic conditions is tough. Protective clothing can be heavy and cause overheating and sweating upon exertion. And hands and feet can grow numb despite wearing such gear. To keep military personnel more comfortable and battle-ready in bitterly cold climes, scientists are conducting research aimed at creating high-tech fabrics that heat up when powered and capture sweat.

Optical Method Detects Weak Spots in Jet Engine Coatings

Researchers have demonstrated, for the first time, that an optical analysis method can reveal weak areas in ceramic thermal barrier coatings that protect jet engine turbines from high temperatures and wear. The technique could be used to predict how long coatings would last on an airplane. The lifetime of a thermal barrier coating used on airplane turbine blades can range from as little as 1,000 hours up to 10,000 hours at full turbine thrust, even when the coating is applied in the exact same way.

Researchers Achieve Breakthrough in Nuclear Threat Detection Science

Taking inspiration from an unusual source, a Sandia National Laboratories team has dramatically improved the science of scintillators — objects that detect nuclear threats. According to the team, using organic glass scintillators could soon make it even harder to smuggle nuclear materials through America’s ports and borders.
