4X Better Insulation for High-Power Electronic Devices: High Thermal Conductivity Silicon Nitride
With thermal conductivity of 100 W/mK -- four times higher than standard silicon nitride -- high thermal conductivity silicon nitride has emerged as a preferred insulating substrate for next-generation power modules, high-frequency circuits and LED mounting. Nearly as light as silicon carbide but significantly stronger, its high fracture toughness makes it resistant to impact and shocks. It can be polished to a surface roughness of Ra=0.02μm and is exceptionally wear resistant.

World's largest jet engine takes maiden flight
The world's largest jet engine took its first flight over the Mojave Desert on March 13. The GE9X is a showstopper. At 134 in., its fan diameter is so tall and wide that Shaquille O'Neil would fit inside the engine's cover with Kobe Bryant sitting on his shoulders. The whole engine is as wide as the body of an entire Boeing 737. By Tomas Kellner, GE Reports.

Top Tech Tip: How specialized coatings can make mechanical parts harder for extreme industrial applications
Although bearings, gears, rollers, and other precision components are generally made of hardened steel or metal alloys, those used in high-load applications still can fail due to excessive wear, surface fatigue, pitting, galling, and corrosion. To address this problem, product engineers and component manufacturers often turn to specialized PVD (physical vapor deposition) coatings that can further harden the surface of these parts. Oerlikon Balzers provides solid solutions.

Top Tech Tip: Choosing between brush and brushless DC motors -- What are the tradeoffs?
Designing a system that involves motion and performs as intended requires choosing the right motor. The most fundamental decision involves commutation type. In some cases, mechanically commutated brush motors provide the best solution for the budget. In other cases, only brushless DC (BLDC) motors will do. Allied Motion provides a comprehensive review of the technology, along with tips and tricks for choosing the right solution for a given application.

Top Product: World's darkest spray paint
A whole range of products can now take advantage of the world's blackest coating, Vantablack, thanks to the development of a new spray version called Vantablack S-VIS. It is easily applied at large scale to virtually any surface. Vantablack's carbon nanotube matrix structure absorbs virtually all (99.8 percent) incident light, enabling precision optical systems to be optimized. The material's developer, UK-based Surrey NanoSystems, has mimicked the performance of its original Vantablack with this new version that can be sprayed onto objects, rather than deposited using a chemical vapor deposition (CVD) process.

Top Product: Spinning flare nuts eliminate loose fasteners in thin metal sheet applications
PEM SFN spinning flare nuts from PennEngineering become permanently captivated upon installation in thin metal sheets and, when paired with a self-clinching stud or other fixed externally threaded hardware, can eliminate all loose fasteners (including flange nuts) in attachment applications. These one-piece, flanged hex nuts additionally will spin freely in a sheet enabling quick attachment to mating hardware. Their use ultimately promotes savings in assembly time and costs.

50 years ago: NASA solves the 'pogo effect' -- gets one step closer to moon landing
On July 18, 1968, NASA announced that engineers had found a solution to the problem that occurred near the end of the Saturn V rocket's first stage during the uncrewed Apollo 6 mission. During the last 10 seconds of that first-stage burn, the rocket experienced longitudinal oscillations called "pogo effect." Had a crew been onboard, they would have experienced severe vibrations and even possible injury.

12 principles of modern military leadership
Leadership is paramount to the success of any army -- and any organization in general. Leaders not only make life and death decisions sometimes, but directly control the climate and quality of life of their subordinates. But what is the real definition of leadership? Capt. Ron Roberts of the U.S. Army's Asymmetric Warfare Group discusses 12 fundamental leadership principles, as well as several educational and inspirational historical examples. How much do they apply to what you do?

Videos+: Technologies and inspiration in action
Opposed-piston diesel engines are crazy efficient
Jason Fenske from Engineering Explained takes a look at the Achates Power opposed-piston engine, which is packed full of unique technology. The supercharged, turbocharged, diesel three cylinder makes use of six pistons, two of which operate in each cylinder. It's a two-stroke design, meaning every time the pistons come together a power stroke occurs, forcing both pistons away from one another and rotating their respective crankshafts. The two crankshafts are geared together to a common output shaft, which powers the vehicle. Research has shown two-stroke opposed-piston engines to be wildly efficient. Three-cylinder designs are the most efficient, and it's possible to achieve brake thermal efficiencies as high as 55 percent, a massive improvement for road car engines.

Pilot recounts tales of SR-71 Blackbird
The SR-71 reconnaissance aircraft flew missions around the globe at speeds above Mach 3 and altitudes of 85,000 ft or more. Although its many contributions to national security will never be fully revealed to the public, the Skunk Works marvel holds many world aviation records for its speed and altitude. In this interview with former SR-71 pilot Col. Buzz Carpenter, you'll hear a first-hand account of the aircraft's power and majesty.

Festo creates rolling spider-like bot
The pneumatics wizards at Festo, famous for creating nature-inspired bionic creature concepts that also often include electromechanical drives, motors and controllers, and grippers, have unveiled the cartwheeling BionicWheelBot at Hannover Messe 2018. Like its biological model, the flic-flac spider discovered at the edge of the Sahara, the BionicWheelBot can both walk and roll. This machine rolls along the ground by forming a wheel with three legs on each side of its body. Two more legs, which are retracted during running, are then extended. When the spider is rolled up like a ball, these legs push it off the ground and propel it forward in a continuous rolling motion.
