| | Feature articles | U.S. Army 3D prints working grenade launcher and ammo
What's better than a 3D-printed prototype grenade launcher? One that works -- with 3D-printed ammo -- of course. Researchers at the U.S. Army Armament Research, Development and Engineering Center (ARDEC) and industry partners have been working hard to push the envelope in 3D-printing prototype technology. Did they succeed? Yup -- with a bang.

 | Heard of a supersolid? MIT researchers create new form of matter
MIT physicists have created a new form of matter, a supersolid, which combines the properties of solids with those of superfluids. Studies into this apparently contradictory phase of matter could yield deeper insights into superfluids and superconductors, which are important for improvements in technologies such as superconducting magnets and sensors.

 | Make the switch to eco-friendly switches with feeling
Leading consumer, industrial, medical, automotive, and enterprise technology device companies rely on C&K's switches to help them create lighting applications that are environmentally friendly and ideally suited for harsh environments. C&K's most popular tactile switches (the KSA, KSC and KSS models) offer engineers and designers excellent tactile feeling, low profiles, and actuator and sealing options to suit any design. For DIP switch options, the company offers low-profile and standard profile, coded rotary, SIP, and jumper DIP switches. The BD standard profile DIP switch is a popular choice, because it has an extended actuator and an open-bottom construction that allows for solder washing without the need for tape seal.

 | Mike Likes: Hybrid material creates impact-resistant carbon fiber
DSM, the developer and producer of Dyneema ultra-high-molecular-weight polyethylene (UHMwPE) fiber, has found a way to leverage the fiber's extraordinary properties in diversely different end uses. Combining Dyneema with carbon fiber yields a hybrid, thermoset resin-based composite called Dyneema Carbon. The resulting lightweight material can increase impact energy absorption by up to 100% while removing the risk of splintering. As part of a hybrid composite, Dyneema can bring its strengths to products currently using pure carbon fiber: from golf clubs and field hockey sticks to racing bike frames and steering wheels (like the racing steering wheel shown here from OMP).

 | Ultra-high-torque brushless slotless motor
The 22ECT brushless motor is Portescap's latest addition to its Ultra EC mini motor platform line, designed specifically to deliver high torque in a compact size. With its unique coil technology and a patent-pending multipolar rotor design, the 22ECT has been developed to be one of the most advanced and highest performing brushless slotless motors in its class. The 22ECT is specifically optimized for high continuous torque at low to medium speeds, maximizing power between 10 K and 20 K rpm. These motors are capable of delivering two times higher continuous torque than comparable BLDC motors of the same size over the entire low speed range when used with gears. It is available in 60-mm and 82-mm length versions, with hall sensors and 3 different coils to match your speed and voltage requirements.

 | IoT: Hardware cryptography-enabled microcontroller
One of the hardest challenges to solve in a connected system is the ability to ensure that the boot code has not been compromised. The CEC1702 hardware cryptography-enabled microcontroller from Microchip Technology eliminates this issue by making it easy for designers to verify pre-boot authentication and then provide firmware updated from known, trusted resources. This low-power, programmable ARM Cortex-M4-based 32-bit microcontroller offers easy-to-use encryption, authentication, and private and public key capabilities. It allows customer programming flexibility to minimize customer risk. It also provides significant performance improvements when compared to firmware-based solutions.

 | Weird Science: Metal conducts electricity but not heat
There's a known rule-breaker among materials, and a new discovery by an international team of scientists adds more evidence to back up the metal's nonconformist reputation. According to a new study led by scientists at the Department of Energy's Berkeley Lab, electrons in vanadium dioxide can conduct electricity without conducting heat.
