PM helped shave nearly 20 percent off the cost of a lawn mower blade-stop assembly, which won the grand prize in the competition's lawn-and-garden category. Previously, the assembly's drum and pulleys had been machined, cast and stamped. Burgess-Norton Mfg. Co. used PM to add features that ease assembly to the mower blade. Among them are a molded key on the pulleys and hexagonal pockets on the drum. The pulleys are also sinter bonded together into a single component. Burgess-Norton forms the parts to a density of 6.9 g/cm3 with an ultimate tensile strength of 280 MPa and an apparent hardness of 50-80 HRB.

Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.

Cigarette companies are fighting back by buying up e-cigarette manufacturers.
