 | Can hydrogen paste power motorcycles and scooters?
High-pressure hydrogen fuel tanks are not a viable alternative-fuel option for motorcycles and scooters, but researchers in Germany have another plan: POWERPASTE. This experimental material -- which sports a huge energy density -- stores hydrogen in a chemical form at atmospheric pressure and is activated simply by adding water.

 | Top Tech Tip: HVACR -- How to properly clean a condenser coil
Condenser coil cleaning is one of those subjects where there is a fair amount of confusion. Parker Hannifin provides answers to common questions to set the record straight. Why do condenser coil cleaners foam, and evaporator coils usually don't? What is the difference between the acid and non-acid condenser coil cleaners? Learn these things and more in this informative post.

 | Top Tech Tip: 5 top reasons for solder joint failure
Solder joint reliability is often a pain point in the design of an electronic system. According to Tyler Ferris at ANSYS, a wide variety of factors affect solder joint reliability, and any one of them can drastically reduce joint lifetime. Properly identifying and mitigating potential causes of solder joint failure during the design and manufacturing process can prevent costly and difficult-to-solve problems later in a product lifecycle.

 | Top Tech Tip: Stepper or servo motor -- Which should it be?
Bring out the full capacity of your machines through the most efficient mechatronic design. Hurley Gill, Senior Applications/Systems at Kollmorgen, outlines servo and stepper motor baseline capabilities for selection criteria like torque, speed, accuracy, and repeatability. Technical advantages and disadvantages are discussed, helping machine designers select the best motor drive system for their application.

 | Top Product: Alternative to traditional drive systems
Nexen Group has introduced a stainless steel version of its patented precision roller pinion system (RPS). The Nexen RPS engages two teeth simultaneously to achieve superior accuracy with zero backlash at any length. The system is also extremely quiet and 99% efficient. Stainless steel makes the system corrosion resistant, with a long life of up to 36 million meters. Nexen's RPS provides a low-maintenance, durable alternative to rack and pinion, ball screw, and belt drive technology. The RPS is used for a wide range of applications including laser cutting, plasma cutting, and gantry applications.

 | Good beer. Zero packaging accidents.
The Danish division of Carlsberg, one of the leading brewery groups in the world, has significantly improved staff safety and taken steps toward achieving zero accidents since integrating Universal Robots cobots into its Fredericia-based factory. The company invested in two cobots, the space-friendly UR3 and the powerful UR10, to tackle carrying packaging cartons from the pallet to the magazine -- a monotonous and strenuous task that often left staff with repetitive strain or severe cuts. Working in tandem, the cobots can handle up to 500 packaging cartons per hour. Now the company has purchased four additional cobots to further automate its production lines.

Honey, I shrunk the V-8 engine!
Piezo V-8 Linear Motor: Borrowing from the classic design of a V-8 engine to achieve high push/pull and holding forces, patented piezo actuator technology and linear stepping motion design principles come together to create the fastest and strongest non-magnetic drive of its class size. These piezoelectric motors are self-clamping, i.e., at rest or in steady-state mode, they automatically hold the position without any need for power. Learn how this technology can be used in your application.
