‘Nano-Kebab’ Fabric Breaks Down Chemical Warfare Agents

Researchers deposited a thin film of titanium oxide onto a fabric made of nanoscale fibers using a vapor-phase technology called atomic layer deposition. Researchers have created a fabric material containing nanoscale fibers that are capable of degrading chemical warfare agents (CWAs). Uniform coatings of metal-organic frameworks (MOFs) were synthesized on top of the nanofibers, forming unique kebab-like structures. These MOFs are what break down the CWAs, rendering them harmless.

Fragment Tracking Gives Insights Into What Happens In Explosions

Sandia National Laboratories researchers are doing a series of tests that are studying fragmenting explosives in ways that haven’t been possible in the past. The project observes explosively driven fragments with flash X-ray and high-speed cameras. (Photo courtesy of Sandia National Laboratories) A bang and a swirl of dust from detonating 9 pounds of plastic explosive in the desert signaled the beginning of tests that — thanks to advances in high-speed cameras, imaging techniques and computer modeling — will help Sandia National Laboratories researchers study fragmenting explosives in ways that weren’t possible before.

Optimize Production for Agile Manufacturing

This e-book will show how 3D printing can make dramatic improvements in both time and cost efficiency when compared with traditional production methods associated with these applications. Real world examples are also provided to show that these aren’t just hypothetical scenarios. The companies highlighted in this e-book found a way to transform traditional manufacturing applications using FDM technology and bring their operation to a new level.

3D Printed Jigs and Fixtures Save Time and Reduce Cost

There is an often-overlooked additive manufacturing (AM) application with potentially huge financial returns: jig and fixture making. Replacing conventionally manufactured jigs and fixtures with additively manufactured ones will reduce the fabrication expense, while reducing labor and speeding delivery. But that financial advantage is tiny when compared to the profit gains that result from production-floor reductions in labor and time to market. Learn how four owners of Stratasys Fortus 3D printers justified new AM systems based solely on jigs and fixtures.

Composites Self-Heal at Very Low Temperatures

Scientists developed a method of allowing materials, commonly used in aircraft, to self-heal cracks at temperatures well below freezing. A healing efficiency of more than 100% at temperatures of -60 °C was obtained in a glass fiber-reinforced laminate, but the technique could be applied across a majority of self-healing composites.

Navigation System Uses Existing Cell Signals – Not GPS

Simulation results for an unmanned drone flying over downtown Los Angeles showing the true trajectory (red line), with GPS navigation only (yellow line), and GPS aided with cellular signals (blue line). (Aspin Laboratory at UC Riverside) Researchers developed a highly reliable and accurate navigation system that exploits existing environmental signals such as cellular and Wi-Fi, rather than the Global Positioning System (GPS). The technology can be used as a standalone alternative to GPS, or complement current GPS-based systems to enable highly reliable, consistent, and tamper-proof navigation in autonomous vehicles such as unmanned drones.

NASA’s Folding Wing Reduces Drag and Increases Efficiency

The Spanwise Adaptive Wing concept seeks to enhance aircraft performance by allowing the outboard portions of wings to adapt, or fold, according to different flight condition demands. (NASA) NASA’s Spanwise Adaptive Wing (SAW) concept permits the outboard portions of the wings to move to the optimal position during operation. This could increase efficiency by reducing drag, and increasing lift and performance. The ability to achieve an optimal wing position for different aspects of flight may also produce enough yaw control to allow for rudder reduction on subsonic and supersonic aircraft.
